That is useful for provider-side support, abuse investigation, compatibility debugging, traffic analytics, and public app attribution where a provider exposes it. The harness only partially does this today: the hand-rolled DeepSeek adapter sends `User-Agent: deepseek-harness/0.0.1` (`packages/llm/llm-deepseek/src/adapter.ts`), while the pi-ai-backed twin has no harness-owned header path visible in this repo (`packages/llm/llm-pi-ai/src/adapter.ts`). New adapters can therefore omit attribution silently, and a library-backed adapter can drift from the hand-rolled adapter even though [the twin-adapter RFC](../../implemented/architecture/2026-06-13-twin-llm-adapters.md) exists to keep the provider seam honest across both implementations. + +The immediate prompt came from OpenRouter's [App Attribution](https://openrouter.ai/docs/app-attribution) docs. OpenRouter creates app pages and rankings from `HTTP-Referer` plus display/category headers. That is valuable, but it is not the HTTP standard for application identity. The risk is adopting OpenRouter's exact header set as if it were universal, then leaking provider-specific headers to direct DeepSeek requests, future OpenAI/Anthropic/Vertex adapters, test servers, or proxies that log unknown fields indefinitely. + +## Investigation + +- **OpenRouter's mechanism is provider-specific.** Their current docs say app attribution is tracked through `HTTP-Referer` (required), `X-OpenRouter-Title`, and `X-OpenRouter-Categories`; `X-Title` is only accepted for backward compatibility. Their API reference calls the headers optional and says they make the app discoverable on OpenRouter. This is a concrete OpenRouter contract, not an IETF or OpenAI-compatible API standard. +- **In agent tooling, `HTTP-Referer` is an OpenRouter-aware convention, not a general agent convention.** It is common enough that OpenRouter SDKs and OpenRouter examples expose it directly, and frameworks that target OpenRouter usually need a way to pass it through. But agent protocols such as ACP negotiate names, versions, and capabilities in their own initialize messages, while model-provider requests still need HTTP-level identity. "Accepted in the agent world" therefore means "recognized by OpenRouter integrations," not "portable across agent runtimes or providers." +- **Observed coding agents use product/version `User-Agent` strings, sometimes with environment context.** A non-exhaustive public-code survey found OpenAI Codex building `{originator}/{version} ({os} {os_version}; {arch}) ...` and carrying an `originator` header; Google Gemini CLI sending `GeminiCLI[-clientName]/{version}/{model} ({platform}; {arch}; {surface})` or a Cloud Code VS Code variant; Cline's Codex backend client sending `cline/{version} ({platform} {release}; {arch}) node/{nodeVersion}` plus `originator: cline`; SWE-agent setting `swe-agent/{version}` unless the user already supplied a header; Continue setting `Continue/{version}` for its ClawRouter provider plus `X-Continue-Provider`. Aider also appends `Aider/{version} +{website}` to browser-like user agents for web scraping, but that is not a model-provider request path. The pattern is not one exact format; it is product identity in `User-Agent`, with provider-specific side headers only where a provider/backend asks for them. +- **The standards-track general client identity header is `User-Agent`.** RFC 9110 section 10.1.5 defines `User-Agent` as the user-agent software identity, says it is used for interoperability reports and analytics, and says a user agent SHOULD send it on each request unless configured not to. This is the only standard header that directly matches "what product is making this HTTP request." +- **`Referer` is standard, but OpenRouter's `HTTP-Referer` is not the standard field.** RFC 9110 section 10.1.3 defines `Referer` as the URI from which the target URI was obtained and spends significant text on privacy restrictions. OpenRouter instead asks for `HTTP-Referer`, using it as an app URL identifier. That name and meaning are OpenRouter-specific even though it resembles the CGI environment variable form of the standard `Referer` header. +- **`From` is standard but not suitable as a mandatory default.** RFC 9110 section 10.1.2 defines `From` as an email address for the human responsible for a user agent. Robotic agents SHOULD send it so servers can contact an operator, but non-robotic agents should not send it without explicit user configuration because of privacy and security policy concerns. The harness can support an operator contact later, but must not invent one or require it globally. +- **Request-body `user` or `metadata` fields are not app attribution.** Some model APIs expose a stable end-user identifier, request metadata, labels, or project/account headers. Those are useful for abuse monitoring, internal billing, dashboards, or trace correlation, but they either identify the end user rather than the product, are provider-specific body schema, or are not guaranteed to be forwarded through OpenAI-compatible gateways. They are not a substitute for a static application identity header. +- **SDK telemetry headers identify the SDK, not the app.** Official and third-party SDKs often send library/version headers. Those help the SDK maintainer debug their client, but they do not identify "DeepSeek Code" as the application unless the application explicitly supplies a product attribution layer. + +## Proposal + +Make provider request attribution mandatory at the LLM adapter boundary, with a provider-neutral app identity and provider-specific wire mappings. The rule is: every product LLM adapter must send a static, non-secret application identity on every provider HTTP request, and every adapter must have tests proving the identity reaches the wire or, for a library-backed adapter, proving the configured library hook emits equivalent headers. + +For OpenRouter specifically, mandatory attribution means sending **both** the provider-neutral `User-Agent` and OpenRouter's required app identifier, `HTTP-Referer`. `User-Agent` identifies the client software in the standard HTTP way; `HTTP-Referer` is the OpenRouter-specific app URL key that creates the app page and ranking entry. `X-OpenRouter-Title` and `X-OpenRouter-Categories` refine that same OpenRouter app identity. + +The provider-neutral identity should be owned outside individual adapters, ideally in `dsh-llm` or a tiny support package if importing package metadata from `dsh-llm` is too awkward. It should contain only public product facts: + +- product token for `User-Agent`: `deepseek-code` or `deepseek-harness` (settle this when implementation chooses the public product name) +- version: the package/root version, not a manually duplicated constant +- app title: `DeepSeek Code` +- app URL: the public product or repository URL, not a local workspace path +- optional category list for providers that support public app marketplaces, initially `cli-agent` + +The default is mandatory and non-empty. Deployments may override the title/URL/category values for white-label products or forks, but omission must fall back to the harness default rather than suppress attribution. There is no per-request API for the model, user prompt, session id, cwd, user email, API key owner, or local machine identity to influence these fields. + +Wire mapping: + +| Target | Required mapping | +|---|---| +| All HTTP-based adapters | Send `User-Agent` with the product token and version. Include the app URL as a comment only if the final value stays within the conservative syntax in RFC 9110. | +| OpenRouter endpoints | Send `HTTP-Referer`, `X-OpenRouter-Title`, and, when configured, `X-OpenRouter-Categories` in addition to `User-Agent`. Use `X-OpenRouter-Title`, not legacy `X-Title`, for new code. | +| Direct DeepSeek endpoint | Send `User-Agent`; do not send OpenRouter-only headers unless DeepSeek documents an equivalent contract. | +| Future providers | Add a small provider-specific mapper only when that provider documents an app attribution mechanism. Do not reuse `HTTP-Referer` by analogy. | + +Endpoint detection should be explicit. If the adapter has an OpenRouter provider package later, that package always applies the OpenRouter mapper. If an existing OpenAI-compatible adapter can be pointed at arbitrary `baseURL` values, it may recognize `https://openrouter.ai/api/v1` exactly or expose an explicit `provider: 'openrouter'`/`attributionTarget: 'openrouter'` config. It should not infer OpenRouter from arbitrary path fragments or model names. + +For the current twin adapters, this means the pi-ai-backed adapter cannot remain a silent exception. Either configure `@earendil-works/pi-ai` with request headers if the library supports that, wrap or contribute the missing hook upstream, or retire the library-backed adapter from product use until it can honor the same attribution contract. The value of the twin is comparing real implementations under one contract; attribution is now part of that contract. + +## Acceptance criteria + +- `dsh-llm` documents the mandatory app-attribution contract for `LlmAdapter` authors. +- A shared helper constructs the default app identity and the standard `User-Agent` value from package metadata, so adapters do not hand-copy `deepseek-harness/0.0.1` constants. +- `dsh-llm-deepseek` sends the shared `User-Agent` on direct DeepSeek requests and keeps the existing mock-server assertion, updated to the shared value. +- The OpenRouter mapping, wherever implemented, sends `HTTP-Referer`, `X-OpenRouter-Title`, and optional `X-OpenRouter-Categories`, with a test that uses an OpenRouter base URL or explicit OpenRouter target and asserts the exact headers. +- `dsh-llm-pi-ai` either sends the same attribution headers through a real library hook or is removed from adapter registration paths with a follow-up RFC explaining why the twin contract no longer justifies the maintenance cost. +- No app-attribution field carries secrets, local paths, session ids, prompt text, model output, user email, or per-user stable identifiers. +- The relevant adapter READMEs mention the attribution policy and the OpenRouter-specific mapping only where that mapping can actually be enabled. + +## Alternatives considered + +**OpenRouter headers everywhere.** Rejected. It would satisfy OpenRouter rankings, but it treats a custom OpenRouter contract as a universal standard and sends fields with misleading semantics to providers that did not ask for them. It also risks using `HTTP-Referer` as a generic app URL field even though standard HTTP already has `User-Agent` for product identity and `Referer` for a different browsing-context concept. + +**Only `User-Agent`.** Rejected as incomplete. It is the correct baseline and the only standard mechanism, but it cannot create OpenRouter app pages or marketplace rankings because OpenRouter requires `HTTP-Referer` for that product feature. + +**Only provider account/project identity.** Rejected. Organization/project headers, API keys, cloud accounts, and billing projects identify who pays or owns the request, not which application is sending traffic. They also expose no public app title/category and do not help gateways like OpenRouter build app rankings. + +**End-user `user`/`metadata` fields.** Rejected for this RFC. Those are valuable for abuse monitoring and customer support but describe the human or tenant behind a request. App attribution must be static product identity and safe to send on every request. + +**Config-only opt-in attribution.** Rejected. A default-off setting is exactly how adapters keep drifting. This RFC's policy is mandatory default attribution with overrideable public values, not optional attribution. + +## Risks / what we give up + +**Providers see that traffic comes from DeepSeek Code.** That is the point, but it means deployments that previously blended into generic SDK traffic become identifiable as the harness. Mitigation: send only static public product data and allow forks/white-label deployments to override the public app title and URL. + +**Header support differs by client library.** The hand-rolled adapter can set headers directly; the pi-ai-backed adapter may require an upstream hook or wrapper. This is useful pressure on the abstraction: a provider adapter that cannot set mandatory headers cannot fully implement the harness LLM contract. + +**Version sourcing needs a clean implementation.** The existing `USER_AGENT = 'deepseek-harness/0.0.1'` constant is intentionally manual. Replacing it with package metadata may need a small build-time or runtime helper. That helper is worth it because stale attribution is a low-grade lie that tests can otherwise miss. + +**OpenRouter categorization might go stale.** `cli-agent` is correct for the coding-agent demos and terminal use, but future editor-only or cloud-hosted products might deserve `ide-extension` or `cloud-agent`. Keep categories overrideable and treat them as provider-specific presentation, not the core identity.

Search is the immediate pressure point: the first version should support at least Exa search and Perplexity search — two deliberately different provider shapes (Exa returns a flat `results[]` of `{title, url, highlights, publishedDate}`; Perplexity returns a generated answer plus citations), which is what proves the normalized seam does not just mirror one vendor. Fetch is a separate capability: an anonymous public HTTP(S) fetch backend has transport, security, redirect, decoding, and size-limit concerns that are not the same as provider-backed search. + +The model-facing surface should stay stable while backends change. A search provider swap should not change how the model asks for a query, and a fetch implementation swap should not change how the model asks for a URL. Conversely, a provider package should not expose its own model-facing tool schema just because it has extra provider-specific knobs. + +Putting search and fetch directly in `dsh-tool-web` would make the model-facing tool own provider selection, backend request mapping, transport policy, result normalization, prompt guidance, presentation, and schema registration at once. Letting each provider register its own tool has the opposite problem: tool availability, names, descriptions, and parameters would depend on whichever provider packages happen to load, and provider-specific fields would leak into the model contract. + +There is also a provider-selection question. Existing `tool-bash` and `tool-fs` can rely on Cordis `inject` because there is one backend service key. Web has two independent capabilities (`search` and `fetch`) and potentially multiple providers per capability. `inject: ['web']` proves the seam exists; it does not prove a usable search or fetch provider exists, and it does not define which provider should win when several are registered. + +## Proposal + +Introduce web access as a first-class capability seam following [the capability-seam RFC](../../implemented/architecture/2026-06-13-capability-seams.md): + +1. `@deepseek-ai/dsh-web` (`packages/web/web`) owns `ctx.web`, provider registration, provider selection, shared request/result vocabulary, and web-specific errors. +2. Provider packages implement concrete backends and register capabilities with `ctx.web`, for example `@deepseek-ai/dsh-web-search-exa`, `@deepseek-ai/dsh-web-search-perplexity`, and `@deepseek-ai/dsh-web-fetch-local`. +3. `@deepseek-ai/dsh-tool-web` (`packages/web/tool-web`) owns the model-facing `web_search` and `web_fetch` tool schemas, prompt sections, argument validation, result formatting, and tool-owned presentation over `ctx.web`. + +Providers do not register tools. Providers register capabilities. `dsh-tool-web` is the only owner of model-facing names, descriptions, prompt guidance, JSON schemas, and presentation. + +Search and fetch are separate capabilities and separate model-facing tools, but they are deliberately one seam. `ctx.web` is a single web-access middle layer between provider packages on one side and the tool consumer on the other: one service to inject, one provider-selection policy owner, one abort/error vocabulary, one place a product configures "how this harness reaches the web." The two halves do not share a request schema and have no shared business logic — search normalizes provider-backed discovery into a portable result with optional answer text and citeable sources, while fetch retrieves a concrete public HTTP(S) URL and returns a status code plus bounded decoded content — but they are parallel registries on one capability surface, not two surfaces. The cost is a `WebService` whose registry/status/exec methods come in `Search`/`Fetch` pairs; that parallelism is intentional, not a missed extraction. Splitting into `dsh-search` and `dsh-fetch` is the rejected alternative below. + +`dsh-tool-web` should register model-facing web tools when the product has enabled those tools and the `ctx.web` seam is present. Backend availability is an execution-time concern, not a schema-registration concern: + +- Register `web_search` when web search is enabled for the product/app. +- Register `web_fetch` when web fetch is enabled for the product/app. +- Do not unregister a tool merely because its selected provider is missing, misconfigured, missing credentials, ambiguous, or temporarily unavailable. +- Resolve the provider at execution time, and return a structured `WebError` when the selected capability cannot run. + +This keeps the model schema stable without making plugin load order, credential state, or HMR timing part of the model-facing contract. If web search is enabled but no usable search provider exists, `web_search` remains visible and execution fails with a structured `WebError` such as `WEB_PROVIDER_UNAVAILABLE` or `WEB_PROVIDER_CONFIGURED_UNAVAILABLE`. If a provider appears after `dsh-tool-web`, the next execution can use it without changing the schema. If a provider disappears mid-call, execution fails with a structured `WebError` instead of silently choosing another provider or falling through to `UNKNOWN_TOOL`. + +The first version's provider-change signal is intentionally small. `web/providers-change` has no payload, carries no capability graph, and does not expose provider metadata. It means only "the provider registry changed; observers may recompute status from `ctx.web`." `searchStatus()` and `fetchStatus()` remain derived, not stored, and they are diagnostics plus execution-resolution inputs rather than tool-schema visibility switches. + +## Package topology + +The three-package interface/implementation/consumer split follows bash and filesystem, but the *interface* package is closer to the LLM seam. `LlmService` (`packages/llm/llm/src/index.ts`) is a name-keyed provider registry: `registerAdapter(models, adapter)` stores adapters in a `Map`, returns a disposer, throws `DUPLICATE_ADAPTER` on duplicate keys, and throws `NO_ADAPTER` at resolution time. `ctx.web` follows that registry shape, but has two capability kinds and one small selection-status layer so diagnostics and execution can explain why a search or fetch capability can or cannot run. + +The dependency direction mirrors bash and filesystem: + +```text +@deepseek-ai/dsh-tool-web --depends on--> @deepseek-ai/dsh-web <--depends on-- @deepseek-ai/dsh-web-search-exa + consumer interface implementation + <--depends on-- @deepseek-ai/dsh-web-search-perplexity + implementation + <--depends on-- @deepseek-ai/dsh-web-fetch-local + implementation +``` + +At runtime, provider packages register capabilities with `ctx.web`; `tool-web` reads capability status and registers stable tools with `ctx.tools`: + +```mermaid +flowchart LR + exa["@deepseek-ai/dsh-web-search-exa"] -->|registerSearchProvider| web["@deepseek-ai/dsh-web / ctx.web"] + perplexity["@deepseek-ai/dsh-web-search-perplexity"] -->|registerSearchProvider| web + fetchLocal["@deepseek-ai/dsh-web-fetch-local"] -->|registerFetchProvider| web + toolWeb["@deepseek-ai/dsh-tool-web"] -->|searchStatus/fetchStatus| web + toolWeb -->|ctx.tools.register| webSearch["tool: web_search"] + toolWeb -->|ctx.tools.register| webFetch["tool: web_fetch"] +``` + +`@deepseek-ai/dsh-web` depends only on Cordis and low-level harness support.

It does not import tool, agent, session, LLM, or provider packages. + +Provider packages depend on `@deepseek-ai/dsh-web` and Cordis. They own credentials, endpoint config, provider-specific request mapping, provider-specific response parsing, and provider-specific error translation into `WebError`. They issue network requests with the platform-native `fetch` (Node 24), mirroring `@deepseek-ai/dsh-llm-deepseek`'s adapter, NOT a cordis HTTP-client service (`ctx.http`/`@cordisjs/plugin-http`) — even where a Perplexity provider's request is shaped like an OpenAI-compatible chat completion, that wire shape is a provider-private detail and does not make the provider depend on `ctx.llm`. + +`@deepseek-ai/dsh-tool-web` depends on `@deepseek-ai/dsh-web`, `@deepseek-ai/dsh-tools`, `@deepseek-ai/dsh-system-prompt`, and Cordis. It never imports concrete provider packages. + +## `ctx.web` contract + +`ctx.web` is a provider registry plus a provider-selecting execution surface. The registry half should stay close to `LlmService`: a `Map` per capability kind, `registerSearchProvider` / `registerFetchProvider` methods that return disposers, duplicate ids that throw `WebError`, and execution-time resolution that throws when the selected provider is absent or unusable. The exact TypeScript signatures belong to the implementation PR, but the seam should expose this shape: + +```ts +interface WebSearchProvider { + readonly id: string + status(): WebProviderStatus + search(request: WebSearchRequest, exec?: WebExecContext): Promise +} + +interface WebFetchProvider { + readonly id: string + status(): WebProviderStatus + fetch(request: WebFetchRequest, exec?: WebExecContext): Promise +} + +interface WebService { + registerSearchProvider(provider: WebSearchProvider): () => void + registerFetchProvider(provider: WebFetchProvider): () => void + + searchStatus(): WebCapabilityStatus + fetchStatus(): WebCapabilityStatus + + search(request: WebSearchRequest, exec?: WebExecContext): Promise + fetch(request: WebFetchRequest, exec?: WebExecContext): Promise +} + +interface WebExecContext { + readonly signal?: AbortSignal +} +``` + +`WebExecContext` is execution control, not business input. The first version should carry only `signal` so `tool-web` can propagate turn cancellation, tool timeout, and agent disposal into provider network requests, SSE readers, and expensive decoding. It should not pass `ToolExecution` through the seam, because that would make `dsh-web` depend on `dsh-tools`. + +`@deepseek-ai/dsh-web` should also declare a Cordis event named `web/providers-change`. Provider ids are stable strings and unique within their capability kind. Registering a duplicate search provider id or duplicate fetch provider id should fail rather than silently replace the old provider. Provider registration returns a disposer, emits `web/providers-change` after successful registration, and emits it again when the provider is disposed. The registry should follow the existing `ctx.tools.register()` / `ctx.systemPrompt.section()` pattern: wrap the mutation in `ctx.effect()`, install the rollback disposer before emitting `web/providers-change`, and let a throwing registration-time change listener roll back the just-added provider instead of leaking it into the registry. + +## Provider status and selection + +Provider status and capability selection are separate concepts, but both stay minimal. A provider reports only whether that concrete implementation is usable by cheap local checks such as credential presence or parseable endpoint config. A provider `status()` must not make network calls. The service reports whether the capability has a selected usable provider, or why execution would fail. + +`LlmService` has no status type at all: availability is expressed as registry membership plus a resolution-time throw. `ctx.web` needs a small status answer because product apps, diagnostics, tests, and execution can report precise provider-selection failures without probing individual providers from the tool layer. Status must be derived from the configured provider id, registered providers, and each provider's cheap local `status()` on each call; it must not be stored as mutable service state. + +`WebCapabilityStatus` stays intentionally small: `available` plus a `reason` discriminant, and the selected `providerId` on the available branch so diagnostics can report which provider won. It does NOT carry the per-reason payload (the unavailable provider id, the ambiguous candidate set, the underlying provider-unavailable reason). That branchable detail lives in the structured `WebError` thrown at execution time, which is the surface callers route on; duplicating it into the status union would give the same fact two homes that can disagree. `searchStatus()` / `fetchStatus()` answer "can this capability run, and if not, in which broad category does it fail" — enough for startup diagnostics and the execution-resolution decision — and the thrown error answers "exactly which provider/ids/reason." + +`WebProviderStatus` is an input to selection, not a health system. `tool-web` reads only the aggregated `searchStatus()` / `fetchStatus()`, never each provider's `status()` directly, so selection policy has one owner. + +```ts +type WebProviderStatus = + | { readonly available: true } + | { readonly available: false; readonly reason: 'missing-credential' | 'misconfigured' } + +type WebCapabilityStatus = + | { readonly available: true; readonly providerId: string } + | { readonly available: false; readonly reason: 'none' | 'configured-missing' | 'configured-unavailable' | 'ambiguous' } +``` + +Selection must not depend on registration order.

The only model-facing argument is: + +- `query`: required string. + +`max_results` is NOT exposed to the model in the first version. It is a `dsh-tool-web`-layer decision: the tool sets the result bound — a default of `8` (aligning with OpenCode's Exa default), as an exported constant mirroring `dsh-tool-fs`'s `READ_LIMIT` / `GREP_LIMIT` — and passes it to the seam as `maxResults` on the `WebSearchRequest`. Keeping it off the model schema means the model just asks a question and the product controls how much context comes back; the field can be promoted to a model-facing argument later without breaking the seam. + +`maxResults` flows tool → seam → provider, and the bound is enforced on the way back: + +- `dsh-tool-web` owns the value and puts it on `WebSearchRequest.maxResults`. +- `ctx.web` passes the request through to the selected provider unchanged. +- A provider should apply `maxResults` at the request layer when its API supports it (Exa's `numResults`), as a cost/latency optimization. +- `ctx.web` enforces the bound on the result: if a provider returns more than `maxResults` sources — because its API has no result-count control (Perplexity) or ignored the hint — the seam truncates `sources[]` to `maxResults` and sets `WebSearchResult.truncated` to `true` before returning. This makes the bound a single cross-provider guarantee the model-facing layer can rely on, rather than something each provider must remember to honor. + +The seam request should not include provider-specific controls such as Perplexity model selection, search recency, domain filters, Exa `livecrawl`, Exa `type`, regional hints, generated-answer budgets, or search depth in the first version. Those fields should be added only when they have provider-neutral semantics that both the tool schema and selected providers can honor honestly. + +```ts +interface WebSearchRequest { + readonly query: string + /** Upper bound on returned sources; the seam truncates to it. Omitted = no bound. `dsh-tool-web` always sets it. */ + readonly maxResults?: number +} + +interface WebSearchResult { + readonly providerId: string + readonly query: string + readonly content?: string + readonly sources: readonly WebSearchSource[] + readonly truncated: boolean +} + +interface WebSearchSource { + readonly url: string + readonly title?: string + readonly snippet?: string + readonly publishedAt?: string +} +``` + +`content` is optional provider-generated answer text, search context, or summary. `sources[]` is the portable citation surface. A source always has a URL; title, snippet, and `publishedAt` are optional because not every provider returns them. `title` should not be required: Perplexity-style citations may provide only URLs, and forcing adapters to invent titles would make the seam lie. `dsh-tool-web` can render `title ?? hostname(url)` for display. `publishedAt` is an optional publication/crawl timestamp as an ISO-8601 string — Exa returns it as `publishedDate` on each result and Perplexity returns a `date` on search results, so it is real provider data, not derived; the seam carries it as a string and leaves date parsing to the consumer. + +Exa search should map each entry of the provider's flat `results[]` into a `WebSearchSource`: `url` ← `url`, `title` ← `title`, `snippet` ← the first `highlights[]` entry (an entry with no highlight has no portable snippet and is dropped), `publishedAt` ← `publishedDate`. Exa returns no provider-generated answer, so `content` is omitted. Perplexity search should map `choices[0].message.content` to `content` and prefer the structured top-level `search_results[]` for `sources[]` — `url` ← `url`, `title` ← `title`, `snippet` ← `snippet` (often empty), `publishedAt` ← `date` — falling back to the URL-only `citations[]` array only when `search_results` is absent (those sources carry just a `url`). If a provider returns fewer structured fields than the seam supports, the adapter omits those optional fields. + +Full page retrieval remains the job of `web_fetch(url)`. Search snippets are discovery context, not fetched page bodies. + +## Fetch request and result schema + +The first `web_fetch` implementation should be an anonymous public HTTP(S) fetch provider, likely `local-http`. It should fetch bytes from a concrete URL, apply the basic transport hygiene below (http/https-only, credential rejection, byte/time caps, cross-origin redirect blocking), decode textual content, and return only the minimal model-useful result: final URL, status code, body, and truncation. It should not carry browser cookies, editor credentials, git credentials, internal auth tokens, or implicit access to private services. (Full SSRF / private-network blocking is deferred — see [Deferred work](#deferred-work).) + +The first seam request should stay smaller than OpenCode's model-facing tool: + +- `url`: required HTTP(S) URL. +- `timeoutMs`: optional positive number capped by the provider. + +The seam request deliberately does not include `format`, `prompt`, or provider-specific extraction controls. `format` is a presentation decision over a fetched resource; `prompt` is a higher-level LLM summarization instruction; extraction APIs such as Firecrawl, Exa, Tavily, or Parallel may not expose a concrete HTTP response. If the product later needs provider-backed page extraction, add a separate `web_extract` capability or explicitly widen this RFC before implementation. Do not smuggle extract semantics into `web_fetch` by making every HTTP field optional. + +HTTP status is part of the fetched resource state, not automatically a tool failure. A successful network fetch of a `404` or `500` response should return `WebFetchResult` with the status code and a bounded decoded body when the content type is supported. `WebError` is for failures to safely retrieve or represent the resource: invalid or blocked URL, redirect policy violation, timeout, abort, response too large, unsupported content type, provider failure, or network failure. + +```ts +interface WebFetchRequest { + readonly url: string + readonly timeoutMs?: number +} + +interface WebFetchResult { + readonly providerId: string + readonly url: string + readonly statusCode: number + readonly body: WebFetchBody + readonly truncated: boolean +} + +type WebFetchBody = + | { readonly kind: 'html'; readonly content: string } + | { readonly kind: 'text'; readonly content: string } +``` + +`WebFetchResult.url` is the final URL after allowed redirects. The request URL is already present in `WebFetchRequest`, so the first version should not add separate `requestedUrl` and `finalUrl` fields. + +`WebFetchBody` is a CLOSED discriminated union owned by `dsh-web`, not a merge-extensible map. The merge-extensible pattern (`ContentBlockMap`) exists for variants that independent plugins introduce and the seam cannot foresee; body kinds are not that — `dsh-web` declares the kind, the fetch provider decodes it, and `dsh-tool-web` renders it, so a new kind is a coordinated change across three known packages, not a plugin extension. Keeping it closed buys compile-time exhaustiveness: consumers `switch` on `kind` ending in `default: assertNever(body, …)`, so adding a kind breaks compilation at every consumer that must render it (e.g. `tool-web`'s `html`→markdown vs `text` passthrough) until that arm is written. Each arm stays its own object literal even when the fields coincide today, leaving room for arm-specific fields (a future `pdf` body's `pageCount`, a `json` body's parsed value) without reshaping the type. Since the harness is unreleased, extending this closed union later is free (no migration, no compat shim). + +The provider owns safe resource retrieval: URL validation, HTTP transport, redirect policy, timeout, abort propagation, byte caps, charset decoding, content-type classification, and binary rejection. `dsh-tool-web` owns presentation: HTML-to-markdown, HTML-to-text, truncation formatting for the model, and future summaries. + +The fetch provider must define resource controls before the tool ships: + +- Accept only `http:` and `https:` URLs. +- Reject credentials in URLs. +- Enforce maximum URL length, response byte cap, decoded body character cap, timeout, and redirect hop cap. +- Propagate abort signals through network fetches and expensive decoding. +- Automatically follow only same-origin redirects. +- Fail cross-origin redirects with `WEB_REDIRECT_BLOCKED`, requiring a fresh tool call and therefore a fresh provider/permission decision. (Claude Code's WebFetch uses this same model — it does not auto-follow a cross-host redirect; it returns the redirect target to the model for a fresh call.) +- Use an explicit product user agent rather than silently impersonating a browser by default. + +SSRF / private-network protection (blocking private, loopback, link-local, multicast, and otherwise non-public destinations, with DNS-resolve-then-validate to defeat rebinding and per-hop re-validation on redirects) is **deferred** — see [Deferred work](#deferred-work). Until it lands, `web_fetch` is an SSRF primitive and must not be enabled in a deployment that can reach sensitive internal network targets. + +## Tool consumer behavior + +`dsh-tool-web` owns two `ToolDefinition`s: `web_search` and `web_fetch`. It owns model-facing JSON schemas, snake_case argument names, prompt sections, result rendering to `ContentBlock[]`, `presentCall`, and `presentResult`. + +`dsh-tool-web` must not enumerate providers or call provider `status()` directly. Its execution path is `ctx.web.search()` / `ctx.web.fetch()`, and any optional startup diagnostics should read only `ctx.web.searchStatus()` / `ctx.web.fetchStatus()`. That keeps provider selection in one layer; otherwise the tool package could decide one provider is usable while execution resolves a different state. + +Tool registration in the first version is a minimal stable sync: + +1. On plugin startup, read the product/app config that enables or disables web search and web fetch. +2. If web search is enabled, register `web_search` and keep that tool's disposer. +3. If web fetch is enabled, register `web_fetch` and keep that tool's disposer. +4. Do not dispose either tool merely because `ctx.web.searchStatus()` or `ctx.web.fetchStatus()` is unavailable. +5. Dispose registered tools when the `tool-web` fiber is disposed. + +Provider status changes affect execution results and diagnostics, not whether the model-facing schema exists. If a product wants no web tools at all, it disables `dsh-tool-web` or the individual web tool in config; if it wants web tools but the backend is misconfigured, the model sees a structured tool error at execution time. + +Prompt guidance should explain the semantic split: use `web_search` for discovery and current information, then use `web_fetch` when the model needs the content of a specific URL. The prompt and tool result should tell the model to cite relevant URLs with markdown links. + +The model-facing output should be text-first because current tool results are `ContentBlock[]`, but the seam outcome should stay structured so UI presentation and future adapters do not have to scrape rendered text. + +## Errors + +`dsh-web` should define `WebError extends HarnessError` with stable codes. Initial codes should include only states that callers may reasonably branch on: + +- `WEB_PROVIDER_UNAVAILABLE` +- `WEB_PROVIDER_CONFIGURED_MISSING` +- `WEB_PROVIDER_CONFIGURED_UNAVAILABLE` +- `WEB_PROVIDER_AMBIGUOUS` +- `WEB_DUPLICATE_PROVIDER` +- `WEB_INVALID_URL` +- `WEB_BLOCKED_URL` +- `WEB_REDIRECT_BLOCKED` +- `WEB_FETCH_TOO_LARGE` +- `WEB_FETCH_TIMEOUT` +- `WEB_ABORTED` +- `WEB_UNSUPPORTED_CONTENT_TYPE` +- `WEB_PROVIDER_ERROR` + +`WEB_DUPLICATE_PROVIDER` is thrown synchronously from `registerSearchProvider` / `registerFetchProvider` when an id is already registered for that capability kind (the analogue of `LlmService`'s `DUPLICATE_ADAPTER`); it is a registration-time programming error, not an execution outcome, but shares the `WebError` code space so callers see one taxonomy. `WEB_PROVIDER_ERROR` is the catch-all for a provider's own failure surfaced through the seam, including network/transport failure in `web-fetch-local` (DNS, connection refused, TLS); the first version does not split out a separate `WEB_NETWORK` code, but the provider should set a descriptive message so the model and logs can tell a network failure from a provider API failure. + +Tool execution should let these errors flow through `ToolRegistry.execute()`, which already converts `HarnessError` into an error tool result with structured metadata. The model gets a readable error message; hooks, tests, and UI code can route on the stable code. + +## Tests + +Tests should prove the seam contract without turning this RFC into an implementation checklist. + +`dsh-web` tests cover provider registration and disposal, duplicate provider ids, `web/providers-change` emission, rollback when a registration-time `web/providers-change` listener throws, `searchStatus()` and `fetchStatus()` for the selection table above, execution-time provider resolution, `maxResults` truncation of `sources[]` with `truncated` set when a provider over-returns, abort propagation through `WebExecContext.signal`, and structured `WebError` codes. + +Search provider tests cover request mapping, response parsing into `content` plus `sources[]`, missing credentials, provider errors, timeout/abort, truncation, and a self-skipping with-key smoke test for each real provider. Perplexity fixtures must include URL-only citations so the optional source fields stay honest. + +`dsh-web-fetch-local` tests cover real HTTP behavior using a local test server: valid text and HTML fetches, non-2xx HTTP responses returned as results, byte/decoded-body caps, timeout, abort, invalid URLs, credential-in-URL rejection, cross-origin redirect blocking, unsupported content types, and product user agent. (Private-destination/SSRF blocking tests come with that deferred work.) + +`dsh-tool-web` tests execute through the real tool registry. They verify schema registration follows product/app tool enablement rather than provider availability, unavailable or ambiguous providers produce structured execution errors, argument validation, formatting of successful search/fetch results, structured error propagation, and cleanup on disposal. + +Integration tests should load the real seam, provider, and tool packages together and execute through `ctx.tools.execute()` rather than calling providers directly. If wiring the tools into an ACP-facing example changes editor-visible transcripts, add or update the relevant snapshot scenario in the same change. + +At least one test must drive these packages through their REAL cordis Loader/export path, not a hand-built `ctx.plugin({...})` mount, so a broken export shape is caught (see [docs/postmortem/0001](../../../postmortem/0001-acp-default-export-drops-inject.md) and `packages/AGENTS.md` § plugin-export-shape). The two shapes need different guards: `dsh-web` and the provider packages are **services** (`export default` the class) and a stray extra export would surface as a missing service; `dsh-tool-web` is a **namespace plugin** (named `name`/`inject`/`apply`, NO default), and because it has `inject`, a stray `export default apply` makes `unwrapExports` drop the `inject` and the plugin throws `cannot get property … without inject` the moment it loads — so a Loader smoke that boots tool-web over `ctx.web` catches it. Prove the guard bites: add `export default apply` to `tool-web`, watch the smoke go red, revert. + +## Migration plan + +This is new capability work, so no compatibility migration is required while the harness is unreleased. + +Land the work in seam order: + +1. Add `packages/web/web` with `ctx.web`, provider registration, provider status, capability status, selection, request/result/error types, and contract tests. +2. Add `packages/web/web-search-exa` with parser/unit tests and a self-skipping real-provider smoke test. +3. Add `packages/web/web-search-perplexity` with parser/unit tests and a self-skipping real-provider smoke test. +4. Add `packages/web/web-fetch-local` with local HTTP behavior tests. +5. Add `packages/web/tool-web` with config-driven tool registration, prompt sections, model formatting, presentation, and tool-registry tests. +6. Wire product app/example configs only after package behavior is stable, because tool schemas and prompt sections affect agent behavior and snapshots. +7. Update `docs/architecture.md`, `packages/README.md`, package READMEs, generated Cordis catalogs if new events/services are added, and maintenance scripts. + +## Alternatives considered + +### Let each provider register its own model-facing tool + +This matches the most flexible provider-plugin systems: every provider can expose its full native schema. It is rejected for the harness because it gives provider packages ownership of model-facing names, descriptions, prompt guidance, and result formatting. Multiple search providers would produce duplicate tool names or provider-specific tool names, and the model would learn backend details instead of a stable product capability. + +### Put provider dispatch directly in `dsh-tool-web` + +This resembles OpenCode's local web search: one stable `websearch` tool dispatches to Exa or Parallel internally. It is acceptable for a small product path but wrong as a harness foundation. The tool package would own provider selection, credentials, request mapping, transport, response parsing, and presentation, making it hard to add Exa and Perplexity without baking their differences into the tool schema. + +### Split search and fetch into two seams (`dsh-search`, `dsh-fetch`) + +Tempting because the two halves share no request schema and no business logic, so each would map cleanly onto the bash/fs three-package template, and the `Search`/`Fetch` method-pair duplication on `WebService` would disappear. Rejected because the shared machinery — provider-id registry, registration-order-independent selection policy, abort propagation, the `WebError` taxonomy, and the product-facing "how this harness reaches the web" config surface — is real and would otherwise be duplicated across two near-identical seams. One `ctx.web` middle layer gives the product a single thing to inject and configure and gives provider selection one owner. The price is the parallel `searchX`/`fetchX` method pairs, which is accepted deliberately. + +### Choose the first registered provider + +Rejected. Registration order is not a product policy. It can change with config order, plugin loading, HMR, or refactors. Provider selection must be explicit, or automatic only when exactly one usable provider exists. + +### Treat Firecrawl/Exa/Tavily/Parallel extraction as fetch + +Rejected for the first version. Those providers often return extracted or summarized content rather than a concrete HTTP response. If the product needs extraction, design `web_extract` or deliberately widen the fetch seam later. + +### Mirror Claude Code's `url + prompt` WebFetch shape + +Rejected for the seam. `prompt` turns fetch into LLM summarization and couples public-web retrieval to a model provider. The harness seam should fetch and decode deterministically; `dsh-tool-web` can later offer summaries as a presentation mode without making `ctx.web` depend on `ctx.llm`. + +## Risks + +**The search schema may be too thin.** Exa and Perplexity both expose useful provider-specific controls. The first version should resist adding them until they can be defined provider-neutrally and enforced honestly by both tool registration and provider execution. + +**Perplexity citations may be sparse.** A citation may be only a URL. Making `title` and `snippet` optional keeps the seam truthful but means `tool-web` must render useful fallback labels. + +**Stable tool registration can defer misconfiguration to execution.** Keeping the tool visible is correct when the product enabled web access, but product apps that expect web search should surface `configured-missing`, `configured-unavailable`, and `ambiguous` loudly during startup diagnostics so users do not discover setup problems only after the model calls the tool. + +**Provider state can change after startup.** A tool can be visible in the request assembled at step start and lose its provider before execution. The execution path must resolve again and fail with a structured error. + +**Fetch is a network boundary, not just a read-only tool.** `web_fetch` can still reach sensitive network targets or exfiltrate data through URLs. The first version ships only the basic transport hygiene (http/https-only, credential rejection, byte/time caps, cross-origin redirect blocking); SSRF / private-network blocking is deferred (see [Deferred work](#deferred-work)), so until it lands `web_fetch` must not be enabled where it can reach internal targets. + +**Large web content can damage context quality.** Providers must enforce byte/character caps and report `truncated`; `tool-web` must format bounded model output with clear continuation or follow-up guidance. + +## Deferred work + +- SSRF / private-network protection for `web_fetch`: block private, loopback, link-local, multicast, and otherwise non-public destinations so `web_fetch` is not an SSRF primitive. Doing it correctly is more than a URL-string check — it needs DNS-resolve-then-connect-to-the-validated-IP (to defeat DNS rebinding / TOCTOU), per-hop re-validation across redirects, and IPv6 edge handling (private ranges, IPv4-mapped addresses). Neither reference implementation surveyed does IP-level blocking (OpenCode does a prefix check then fetches; Claude Code relies on a centralized hostname blocklist plus a "private URLs will fail" prompt), so there is no implementation to copy and this is the harness's only SSRF defense — it warrants its own focused design/spike. Until it lands, `web_fetch` must only be enabled in deployments that cannot reach sensitive internal targets. +- A `pdf` `WebFetchBody` kind: the `local-http` provider decodes text-extractable PDFs (best-effort, capped, `truncated`) into a `{ kind: 'pdf'; content; pageCount? }` arm, and `tool-web` renders it. This is fetch, not `web_extract` — PDF retrieval is a concrete HTTP 200 plus deterministic local decoding, not provider-side extraction of a non-HTTP resource. Adding it is a coordinated change across `dsh-web` (declare the arm), the provider (decode + narrow "binary rejection" to "reject binary except text-extractable PDF"; scanned/image PDFs needing OCR stay out of scope), and `tool-web` (render). The closed `WebFetchBody` union makes the consumer side fail to compile until the new arm is handled. +- Provider-backed extraction as a separate `web_extract` capability, rather than widening `web_fetch` silently. +- Permission policy integration once the deferred permission system lands. +- Provider-neutral search controls beyond `query` and `maxResults`, once Exa and Perplexity can both honor them honestly. + +## Open questions + +- Should product app packages treat `configured-missing`, `configured-unavailable`, and `ambiguous` as fatal startup errors when web is explicitly configured, or should `dsh-web` only report status and let apps decide? +- Where should permission policy for public web access live once the deferred permission system lands: a dedicated web permission plugin on `tools/execute`, provider config, or both? From d01f5f73b7866b457f00ffbe60b78af39273fc7a Mon Sep 17 00:00:00 2001 From: Dudu-0223 Date: Thu, 25 Jun 2026 15:04:12 +0800 Subject: [PATCH 003/168] Add web capability seam: ctx.web, search/fetch providers, web tools Introduce web access as a first-class capability seam so the model-facing web tools stay stable while backends change. dsh-web owns ctx.web as a provider registry with registration-order-independent selection and the WebError taxonomy; dsh-web-search-exa, dsh-web-search-perplexity, and dsh-web-fetch-local register capabilities into it; dsh-tool-web is the sole owner of the model-facing web_search/web_fetch schemas, prompt sections, and HTML-to-markdown presentation. Search and fetch are deliberately one seam. Providers ship as namespace plugins that register into ctx.web (like an LlmAdapter into ctx.llm), not key-owning services, since multiple search providers cannot each own the key. Tool registration follows product enablement, not backend availability, so load order/credentials never enter the model contract; the seam resolves the provider at execution time and surfaces a structured WebError otherwise. Moves the RFC to implemented/ amended to match what shipped. Example/app configs are intentionally not wired yet (RFC migration step 6). --- .gitignore | 3 + docs/architecture.md | 7 + docs/rfc/README.md | 2 +- .../2026-06-24-web-capability-seam.md | 14 +-

Use the full three-package split when the consumer is independently replaceable; keep interface + consumer together when they are one concern. Don't split preemptively: a capability with one conceivable implementation and one consumer stays one package until proven otherwise. +The web capability uses the same three-package split but folds two capabilities onto one seam: `dsh-web` owns the abstract `ctx.web` service, which is a provider REGISTRY (`registerSearchProvider`/`registerFetchProvider`, registration-order-independent selection, the `WebError` taxonomy) rather than a single backend. Providers register capabilities, not tools — `dsh-web-search-exa`, `dsh-web-search-perplexity`, and `dsh-web-fetch-local` each register into `ctx.web` the way an `LlmAdapter` registers into `ctx.llm`, so they are namespace plugins (`inject: ['web']`), not key-owning services. `dsh-tool-web` is the single consumer that owns the model-facing `web_search`/`web_fetch` schemas, prompt sections, and presentation; it reads only the aggregated `ctx.web.searchStatus()`/`fetchStatus()` and executes through `ctx.web.search()`/`fetch()`, so provider selection has one owner. Search and fetch are deliberately one seam (one thing to inject and configure, one selection policy, one abort/error vocabulary) despite sharing no request schema — see the [web capability seam RFC](rfc/implemented/architecture/2026-06-24-web-capability-seam.md). + > **"Capability" — two unrelated meanings.** (1) The *seam pattern* above ("one plugin provides a capability, another needs it") is realized by plain Cordis **services + `inject`**: a provider registers a service (`ctx.bash`, declared in `interface Context`); a consumer declares `inject: ['bash']` and its fiber stays pending until the service exists, tearing down via HMR if it later vanishes. No extra library is needed. (2) `@cordisjs/plugin-capability` is a different axis entirely — a **permission/capability-security** service (named permissions with inheritance/dependency, tested against a session via `ctx.capability.test`).

Consumers `switch` on `kind` ending in `default: assertNever(...)`, so adding a kind breaks compilation at every consumer until handled.

Providers issue requests with the platform-native `fetch` (Node 24), mirroring `dsh-llm-deepseek`; the `dsh-web-fetch-local` provider owns safe retrieval (http/https-only, credential rejection, byte/char/timeout/redirect caps, same-origin-only redirects with per-hop re-validation, charset decoding) while `dsh-tool-web` owns presentation (HTML→markdown).

The extra entries also tripped the workspace constraints gate, whose expected `files` list covers single-entry and bin packages but not a non-bin multi-entry one. Collapse to a single `.` entry: drop the ./search|./fetch exports and their lib/*.js from package.json files, delete the per-package tsdown override (the root config's lib/types/index.js entry now suffices), and remove the plugin-shaped name/inject exports from search.ts/fetch.ts (renaming each apply to its applyWeb{Search,Fetch}Tool helper, still composed by the root plugin and re-exported from the index).

The per-source `snippet` lives separately in a `text` block's `citations[]` (a `cited_text` keyed by `url`), so the provider joins the two — a result with no citation excerpt simply has no `snippet`.

DeepSeek's `web_search` has no result-count knob (only `maxUses`), so `maxResults` is enforced by the seam (truncating `sources[]` and setting `truncated`).

Dudu-0223 Date: Mon, 29 Jun 2026 17:23:11 +0800 Subject: [PATCH 012/168] fix: address codex review findings on web seam - search providers (exa/perplexity/deepseek): map the parsed response INSIDE the parse try, so a well-formed body of the wrong shape surfaces as WEB_PROVIDER_ERROR instead of escaping as a raw TypeError; a WebError the mapper throws on purpose is re-thrown untouched - web-fetch-local: validate numeric limits at plugin construction (positive finite caps; non-negative integer maxRedirects) rather than constructing a provider with nonsensical values - web-fetch-local: enforce the redirect budget BEFORE resolving each hop, so maxRedirects:N follows exactly N redirects and an over-limit hop reports "exceeded the maximum" rather than misdiagnosing a cross-origin block - drop the stale dsh-tool-web/search and /fetch path aliases (the package no longer declares those subpath exports) - strip trailing EOF blank lines flagged by git diff --check Each fix carries a regression test. --- packages/web/tool-web/src/index.ts | 1 - .../web/tool-web/tests/integration.spec.ts | 1 - packages/web/web-fetch-local/README.md | 4 +- packages/web/web-fetch-local/src/index.ts |

A boundary that is both is mirrored as an agent/* emit ONLY where a live consumer needs the Agent handle. Apply it to the boundary twins: drop agent/step-start and agent/step-end (no production consumer needs the live Agent at a step boundary — consumers read the durable step/start/step/end session events). Keep agent/turn-start/turn-end (the stdio UI labels output by agent.id). Tests that observed step boundaries via the removed emits now observe the durable session events; the pinned behavior is unchanged.

First, several turn/step boundaries existed BOTH as a durable `SessionEvent` (`turn/start`, `turn/end`, `step/start`, `step/end`) AND as a mirrored `agent/*` emit (`agent/turn-start`, `agent/turn-end`, `agent/step-start`, `agent/step-end`). A consumer had two sources of truth for the same fact, and every lifecycle change had to update both. Second, the upcoming Hooks subsystem needs ONE coherent, documented surface to subscribe to — a plugin author (and the Claude Code / Codex hook bridges built on top) must know, without reading the loop, whether to listen on a session event or an agent event, and why. + +This is the foundational change in a stack that adds a Hooks subsystem; it establishes the vocabulary the later PRs (interception-Decision reshape, the `hook/*` durable log, the bridges) build on. + +## Decision + +**Three domains, one job each, with a single boundary rule.** + +- **`session/*` — the durable, replayable FACT log.** Owns `SessionEventMap`; every entry is JSON-only (no live objects). One `session/event` emit per append, plus the `session/flush` parallel durability checkpoint. It is also the live transcript feed: a consumer that wants to render or react to what happened subscribes here, so live rendering and `session/load` replay share one path. +- **`agent/*` — the LIVE runtime surface.** Always carries the live `Agent`. Two shapes: INTERCEPTION waterfalls (`agent/request`, `agent/step-result`, `agent/turn-continuation`) that mutate or veto, and TRANSIENT emits (`agent/status`, `agent/stream-chunk`, `agent/error`, `agent/created`/`agent/disposed`, `agent/queued`, `agent/steering`, and the turn boundaries) that notify with the `Agent` in hand. +- **`tools/*` — the tool registry + execution seam.** + +**The boundary rule:** a durable, replayable fact is a `SessionEvent`; a live interception or a transient/live-object signal is an `agent`/`tools` Cordis event. A datum that is BOTH — a turn or step boundary — lives in the session log, and is mirrored as an `agent/*` emit ONLY where a live consumer provably needs the `Agent` handle at that instant. + +**Applying the rule to the boundary twins (prune case-by-case):** + +- `agent/turn-start` — **KEPT.** The stdio UI (`dsh-ui-stdio`) labels turn output by `agent.id`, which the `turn/start` session event does not carry.

(Note: the ACP bridge does NOT settle on this event — it settles from `session/event` `turn/end` plus `agent/status`; the surviving justification is the stdio UI alone.) +- `agent/step-start`, `agent/step-end` — **REMOVED.** No production consumer needs the live `Agent` at a step boundary; a consumer that wants per-step boundaries reads the durable `step/start`/`step/end` session events. Removing the two emits also simplifies the loop's `closeStep` (one append, no paired emit). + +## Consequences + +- The loop no longer emits `agent/step-start`/`agent/step-end`; `closeStep` appends `step/end` only, and a throwing `step/end` session-event listener is the surviving step-boundary-listener failure path (contained by `closeStep` → `failTurn`, the turn closes balanced). +- Tests that observed step boundaries via the removed emits now observe the durable `step/start`/`step/end` session events — the behavior they pin (boundary ordering, step counting, a throwing boundary listener failing the turn balanced) is unchanged; only the feed they read moved to the canonical one. Per [AGENTS.md "tests document behavior, not golden truth"](../../../../AGENTS.md), the behavior and its test moved together. +- One behavior genuinely shifts and is documented in its test: a throwing `step/start` session-event listener throws INSIDE `session.append('step/start')`, before the loop marks the step open, so no `step/end` is owed (the old `agent/step-start` emit fired after the step was open). The turn still closes balanced with an error. +- This is a partial, conservative realization of the broader [proposed simplification "Stop mirroring durable boundaries as agent events"](../../proposed/simplification/2026-06-20-remove-agent-boundary-mirror-events.md): that RFC proposes removing ALL boundary mirrors (including the turn boundaries and `agent/steering`) and migrating the stdio UI's turn rendering onto `session/event`. This RFC removes only the two step mirrors that have no live consumer; the turn mirrors stay until the stdio UI is migrated.

The turn still closes balanced with an error. +- The loop marks the step open (`stepOpen = true`) BEFORE appending `step/start`, because `Session.append` pushes the event to the log before notifying `session/event` listeners (validation throws happen earlier, before the push — see [the session append contract](../../../core-data-structures/session.md)). So a throwing `step/start` session-event listener runs with the step already open and the event already in the log: the loop's outer catch then calls `closeStep()`, which appends the balancing `step/end`, and the turn closes balanced with an error (`turn/start → step/start → step/end → turn/end` — verified by the invariants oracle in the regression test).

Reusing the ctx.bash seam for that needs two new inputs — but stdin and arbitrary env are exactly what dsh-bash-local's credential scrub exists to keep away from model-driven commands. So this adds them as a TRUSTED-PLUGIN surface: - BashExecRequest + BashExecSpec gain optional `stdin` and `env`. They are plain optionals on the resolved spec (not required-but-nullable like `owner`): a missing one means "none", the safe default, not a security footgun. - dsh-bash-local threads them through resolve/run/start. `env` merges AFTER the credential scrub, so a trusted caller's explicit entry wins even on a credential-shaped name — the scrub guards the harness's OWN ambient creds from model-driven commands, not a trusted plugin. stdin is always a pipe, closed immediately (with bytes when supplied, empty otherwise — EOF as before); an EPIPE from a child that exits without reading is swallowed. - The model-facing dsh-tool-bash NEVER forwards model input into stdin/env (its request is command/workdir/timeoutMs/signal/owner only). A regression guard drives the real tool with adversarial args and asserts the request carries neither field — proven to go red if the consumer ever forwards them. Configurable scrub (in an earlier sketch) is dropped as speculative: the explicit `env` field already gives a trusted caller full control, and no caller needs to broaden the ambient scrub.

The harness already has a perfectly good command runner behind the `ctx.bash` capability seam ([dsh-bash](../../../../packages/bash/bash) → [dsh-bash-local](../../../../packages/bash/bash-local)), with process-group kills, output truncation/spill, and a credential scrub. Reusing it for hook execution means the bridges do not re-implement subprocess plumbing — but the seam had no way to write stdin or set extra env. + +The friction is that those two inputs are **dangerous in exactly the way the seam was built to prevent**. [dsh-bash-local](../../../../packages/bash/bash-local)'s `childEnv()` deliberately scrubs `*KEY*`/`*SECRET*`/`*TOKEN*` from the child environment so the harness's own `DEEPSEEK_API_KEY` cannot leak into model-driven command output (see [AGENTS.md](../../../../AGENTS.md) § Defensive patterns, "Never hand untrusted/model output the ambient environment or predictable paths").

The enforcement lives in the model-facing consumer [dsh-tool-bash](../../../../packages/bash/tool-bash): its `bash` tool builds its `BashExecRequest` from `command`/`workdir`/`timeoutMs`/`signal`/`owner` **only**, and never reads model arguments into `stdin`/`env`. A model that smuggles `env`/`stdin` keys into the tool-call arguments gets them ignored. A regression guard (`tool-bash` "trusted-plugin boundary" tests) drives the real tool with adversarial args and asserts the recorded request carries neither field — and is proven to go red if the consumer ever forwards them. Only in-process plugins (the hooks bridges, native plugins) that construct a `BashExecRequest` directly can set them. + +2. **`env` merges AFTER the credential scrub, so a trusted caller's explicit entry always wins** — even a credential-shaped name. This is correct precisely because the scrub's job is narrow: stop the harness's *ambient* `process.env` credentials from leaking into *model-driven* commands. A trusted plugin that explicitly sets a var has taken responsibility for it; the scrub is not a constraint on trusted callers. `childEnv(extra?)` layers `scrub(process.env)` → `ENV_OVERRIDES` (the model-friendly `TERM=dumb` etc.) → `extra`, last-wins. + +3. **`stdin`/`env` are required-absent-OK (plain optional) on the resolved spec, NOT required-but-nullable like `owner`.** `owner` is required-but-nullable because a *silently* missing owner yields an unowned, cross-session-readable task — a security footgun that a visible `undefined` guards against. `stdin`/`env` have no such hazard: a missing one means "no stdin / no extra env", which is the safe, ordinary case (every model-driven call). So they stay plain optionals, matching `signal`. + +`dsh-bash-local` now ALWAYS spawns stdin as a `'pipe'` and closes it immediately — with the supplied bytes when a trusted plugin set `stdin`, empty otherwise. A closed empty pipe gives a reading child EOF exactly as the previous `'ignore'` (`/dev/null`) did, so the no-stdin path is behavior-equivalent; keeping the `stdio` tuple a literal `['pipe','pipe','pipe']` also preserves the typed `spawn` overload that guarantees non-null `stdout`/`stderr`. A child that exits without reading makes the stdin write fail EPIPE; that error is swallowed (the command's outcome rides on its exit code/output, not the write) so it never crashes the host or rejects `done`. + +## Scope: configurable scrub pattern is NOT included + +An earlier sketch of this work also proposed making `SENSITIVE_ENV_PATTERN` configurable. Validating against the code, that is **speculative and already subsumed**: `run.ts` documents a configurable whitelist as future work, and the new explicit `env` field — merged after the scrub — already gives a trusted plugin full control, including over credential-shaped vars. There is no current caller that needs to *broaden* the ambient scrub (the hazard runs the other way). Adding a config knob now would be a feature with no consumer, against [AGENTS.md](../../../../AGENTS.md) § "Don't add features beyond what the task requires". If a real workflow ever needs to forward a specific ambient credential, the explicit `env` field is the supported path; a configurable scrub can be reconsidered then. + +## Consequences + +The hooks bridges (PR-F) build a `BashExecRequest` with the hook's JSON payload as `stdin` and its `CLAUDE_*`/`PLUGIN_ROOT` vars as `env`, and run it through the same `ctx.bash` everything else uses — no bespoke subprocess code, and the full process-group-kill / truncation / spill machinery for free. The model-facing attack surface is unchanged: the consumer's request-building is the single boundary, guarded by a test that fails if it regresses. The vocabulary addition is documented in [docs/core-data-structures/bash.md](../../../core-data-structures/bash.md) (the `type-equiv` request/spec blocks) and the three bash-package READMEs; the trusted-plugin rule mirrors the existing scrub/predictable-path discipline in [AGENTS.md](../../../../AGENTS.md) § Defensive patterns. diff --git a/packages/bash/bash-local/README.md b/packages/bash/bash-local/README.md index 016f57d2a9..2ae905b628 100644 --- a/packages/bash/bash-local/README.md +++ b/packages/bash/bash-local/README.md @@ -21,7 +21,7 @@ Design surveyed against the bash tools of Claude Code, OpenCode, Codex, and pi; - **Spawn per call, no shell state** — every call is a fresh non-login `bash -c` (deterministic; no rc files).

"Native hooks" are not a package — a native hook is just a cordis plugin on these canonical events; the bridges (a later PR) only translate an external protocol onto the same surface. dsh-agent: - NEW agent/session-start(agent, source) emit (once before turn 1; SessionStartSource startup|resume|clear|compact) — a pure notification, seeds context via inject(). - NEW agent/prompt-submit waterfall → PromptDecision (allow, optionally rewriting the prompt or attaching additionalContext, or block). - RESHAPE agent/turn-continuation boolean → ContinuationDecision ({action:'stop'} | {action:'continue', reason?}; a continue reason is recorded as next-step steering). - New HookContext envelope (required source — inject() would mislabel a missing one). dsh-tools: split the single tools/execute waterfall into tools/pre-execute (PreToolDecision allow/deny/ask gate) and tools/post-execute (PostToolDecision accept/block, optionally replacing content or attaching additionalContext). Core dispatch sits between as plain code; the tool body keeps its inner try/catch so a thrown tool still reaches post-execute as an isError. ToolExecutionResult gains additionalContext (ferried to the loop's per-step buffer). Input rewrite is deliberately NOT offered (a proposed RFC designs it consistently). dsh-session: new `rejected` TurnEndReason — a turn whose whole prompt batch was blocked by prompt-submit. agent-loop firing points: session-start emitted at create (source threaded — startup for create/fork, resume for resume()); prompt-submit per drained message with the always-open-turn rule (a fully-blocked batch is a zero-step rejected turn); the continuation reshape; post-tool additionalContext buffered and appended after all tool/results (adjacency). ACP codec maps rejected→cancelled. A worked native-plugin example (interception.spec.ts) proves all four seams compose end-to-end through the real loop with NO hook/* events (those belong to the bridge lib).

The key reframe driving this design is that **"native hooks" are not a package** — a native hook is just an ordinary Cordis plugin subscribing to the canonical lifecycle events. So the real product is a *powerful, well-typed canonical event surface*; the CC/Codex bridges (a later stack PR) are merely translators that map an external shell-hook protocol onto that same surface. Anything a bridge can do, a plain plugin can do directly — more powerfully (no serialization boundary, full `ctx`, typed returns). + +Before this change the interception surface was incomplete and inconsistent for that goal: there was no per-prompt seam (CC's `UserPromptSubmit`), no session-start signal (CC's `SessionStart`), the single `tools/execute` waterfall conflated the pre-gate and post-inspect phases (CC splits `PreToolUse`/`PostToolUse`), and `agent/turn-continuation` returned a bare `boolean` with no room for a force-continue *reason*. The [event-domain-semantics RFC](../architecture/2026-06-30-event-domain-semantics.md) (the stack's first change) pinned down the three-domain rule and the typed-Decision idiom as the interception convention; this RFC builds the actual seams on top of it. + +## Decision + +Add/​reshape the interception seams so every one returns a small, seam-specific **typed Decision union**, and the set covers the hook points in scope (`session-start`, `prompt-submit`, `pre-tool`, `post-tool`, `stop`-via-continuation). + +**New `agent/*` events** (`dsh-agent`): +- `agent/session-start(agent, source)` — emit, once before turn 1, carrying a `SessionStartSource` (`startup` for a fresh/forked create, `resume` for a reloaded persisted session; `clear`/`compact` reserved).

A batch whose every prompt is blocked does NOT skip the turn — it opens a zero-step turn that closes with `rejected`. This one move resolves three problems at once: (1) turn-enclosure holds (every event has an open turn to live in); (2) `agent/turn-end` fires and the ACP bridge settles normally (mapping `rejected`→`cancelled`) instead of hanging; (3) the block reason is a durable in-turn fact. An `allow`'s `additionalContext` is `inject()`ed into this now-open turn. + +2. **Post-tool `additionalContext` is buffered and appended AFTER all `tool/result`s.** `content`/`feedback` shape the result `execute()` returns, but `additionalContext` is a SEPARATE `context/message`, and a single step can carry multiple tool calls. Appending context right after each result would interleave `result(c1) → context → result(c2)` and break tool-call/result adjacency. So `execute()` surfaces `additionalContext` on its `ToolExecutionResult`, and the loop buffers every per-call context for the step and appends them as `context/message`(s) only after every `tool/result` is appended. + +3. **A forced `continue` `reason` is enqueued through the steering channel**, so the next step's top-of-loop drain records it as steering for the continued turn — next-*step* steering within the SAME turn, not a next-*turn* prompt (matching the existing `hasSteering` force-continue override). + +### Pre-tool INPUT rewrite is DEFERRED (the over-reach signal) + +`PreToolDecision` is allow/deny/ask only — **no `arguments` rewrite**. Output replacement (`PostToolDecision.accept.content`) is safe because `tool/result` is logged AFTER execution (one source of truth). Input rewrite is NOT safe today: `assistant/message` (the model-history source) and `tool/call` (the audit record) are both logged BEFORE execution, and live consumers READ `tool/call.arguments` for presentation (the ACP bridge remembers them for `presentResult`; `dsh-tool-bash` derives the title/cwd/terminal-vs-background from them). A rewrite that changed only execution would make the UI show one command while another RAN. Designing that consistently (rewriting the audit + history + presentation as one unit) is a real consistency-design problem CC itself warns is racy — so it gets its own [proposed RFC](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md), and `TODO(pre-tool-input-rewrite)` anchors it at the loop's pre-execute call site. This does not regress any production consumer (no production `tools/execute` listener mutated `exec.arguments`). The low-level capability to mutate `exec` in a `pre-execute` listener still exists (unadvertised — a test shim uses it to thread a generated id), but it is not a first-class advertised contract. + +### What this PR does NOT do + +It does **not** declare `hook/*` SessionEvents (the durable hook-invocation log) — those belong to the `dsh-hook-protocol` library (a later stack PR), because a native plugin can already use the typed Decisions without a durable hook log. A worked native-plugin example/test in this PR (`packages/core/agent-loop/tests/interception.spec.ts`) proves all the seams compose end-to-end through the REAL loop with NO `hook/*` involved — the concrete proof that "native hooks are just a plugin". Compaction (`PreCompact`/`PostCompact`), the Notification hook, Codex `PermissionRequest`, the permission/`ask` system, and the Stop loop-guard remain deferred (`FIXME(permissions)` marks the `ask`→deny degrade). + +## Consequences + +The canonical interception surface is now complete and uniformly typed: a native plugin returns typed decisions directly, and a CC/Codex bridge maps its protocol fields onto the same unions. The loop gained four firing points (session-start emit, prompt-submit waterfall, the post-tool context buffer, the continuation reshape) and the `dsh-tools` registry runs a two-waterfall pipeline; both are documented in [architecture.md](../../../architecture.md) and the package READMEs, and the decision types in [core-data-structures](../../../core-data-structures/core.md#interception-decisions) + [tools.md](../../../core-data-structures/tools.md). All existing `tools/execute` and `turn-continuation` listeners (tests, docs) migrated to the new seams. The ACP bridge maps the new `rejected` reason to `cancelled` (its codec).

charset=UTF-8 Content-Transfer-Encoding: 8bit Codex's PR-C review found two (A) blockers: - tools/post-execute could corrupt the protected outcome. postExecute passed the mutable `result` to listeners and then read result.callId / spread result on the return paths, so a listener mutating the reference (flipping isError, rewriting callId, injecting an error) escaped the decision channel. Now the authoritative callId/isError/error are SNAPSHOT before the waterfall and the return value is rebuilt from the snapshot + the typed PostToolDecision — the decision is the only sanctioned way to change the outcome, and callId is always exec.callId. Added a regression test that mutates the result reference and asserts it has no effect; proven to fail red on the unfixed code. - Public docs/JSDoc still advertised the removed `tools/execute` waterfall after the split. Swept every current-state reference to tools/pre-execute + tools/post-execute: the ToolRegistry class JSDoc (and the regenerated catalog), loop.ts's ASCII flow (also added the prompt-submit/session-start steps it was missing), the package-map READMEs (packages, core, agent-core), core-data-structures core.md/tools.md, the bash + acp + invariants src/READMEs (the deferred permission gate is the tools/pre-execute deny/ask seam now), the cookbook, and the implemented RFCs whose factual seam catalog drifted. codec.ts's totality prose now lists `rejected`.

Studying the reference implementations (`~/repos/refs/claude-code`, `~/repos/refs/codex`) surfaced a decisive fact: **Codex deliberately reimplements a SUBSET of the CC hook protocol.** Its engine reads the same `hooks.json`, uses the same matcher-group shape, the same exit-code/structured-stdout output contract, and the same command-hook execution model — Codex's source even names the engine after Claude's and comments where it "intentionally diverges." So the two bridges would otherwise duplicate the bulk of the protocol. + +This RFC introduces `@deepseek-ai/dsh-hook-protocol`, a **library** (not a plugin — it registers and injects nothing) holding the genuinely-identical primitives both bridges build on. The split between shared and per-dialect is the design's center of gravity. + +## Decision + +A new `packages/hooks/` group with `hook-protocol` as a pure library. It owns four primitive families and the `hook/*` session events; each bridge (PR-F) owns what genuinely differs. + +**Shared (here):** +- **Matcher** — `matchesMatcher(pattern, query, mode)`. The ONE axis the dialects differ on is collapsed to the `mode` parameter: `claude` treats a pure `[A-Za-z0-9_|]+` pattern as a literal (pipe = exact-match alternation) and anything else as a regex; `codex` is always an unanchored regex. Match-all on absent/`''`/`'*'`; an invalid regex matches nothing (never throws into the loop). +- **Execution** — `runHook(bash, hook, options, now)`. Runs a command hook through the `ctx.bash` seam rather than a bespoke `spawn`: the executor already provides the scrubbed-but-overridable env, process-group kills, and timeout the protocol needs, and `dsh-bash`'s `stdin`/`env` fields (added in the bash-seam PR for exactly this) are the trusted-plugin surface an in-process bridge is allowed to use. It serializes the bridge-built payload to stdin (trailing newline iff CC), honors the hook's `timeoutSec`, and never throws (an executor rejection becomes a non-blocking-error `HookOutput`). +- **Decode** — `parseHookOutput(exit, stdout, stderr)`, the exit-code + structured-stdout codec, producing a dialect-neutral `HookOutput`. Exit `0` → lenient JSON parse of stdout; exit `2` → blocking error with `stderr` as the reason (surfaced as `decision: 'block'` so no caller needs a separate exit-code branch); other → non-blocking error. Parses the full CC superset (`continue`/`stopReason`/`suppressOutput`/`decision`/`hookSpecificOutput.{permissionDecision,additionalContext,updatedInput}`/`systemMessage`); the bridge honors only the subset meaningful for its dialect. +- **Merge** — `mergeHookOutputs(outputs)`, folding multiple matched hooks into one most-restrictive `MergedHookOutcome`: permission precedence **deny > ask > allow**, halt sticky on the first `continue:false`, block reasons joined `\n\n`, context/system-messages accumulated in order. +- **`hook/*` session events** — `hook/invoked` / `hook/result`, declaration-merged into `SessionEventMap` (log-only, like `compact/*` — NOT `SurfaceEventType`s), with `appendHookInvoked`/`appendHookResult` helpers so the invoked/result pairing and turn-enclosure stay consistent across bridges. + +**Per-dialect (the bridges, PR-F):** building each event's stdin payload (CC's base+per-event field sets vs Codex's snake_case with `turn_id`/`model` extras), the dialect's env + `${CLAUDE_PLUGIN_ROOT}` substitution (CC) vs none (Codex), and mapping the neutral `HookOutput`/`MergedHookOutcome` onto the harness's seam-specific typed Decisions (`PreToolDecision`, `PromptDecision`, `ContinuationDecision`, `PostToolDecision`). + +### Why "shared core + per-dialect adapters", not "one parameterized engine" + +A single engine parameterized by a full `dialect` descriptor was considered and rejected. The payload construction and decision mapping are where the dialects genuinely diverge (different field names, different supported outputs, CC's env/substitution); folding those into a data-driven descriptor would make the *bridge* logic indirect — a reader of `dsh-hooks-claude` would have to chase a descriptor to see what payload it sends. Keeping the truly-identical primitives shared (matcher, codec, runner, merge, events) and letting each bridge write its own straightforward payload+mapping keeps each bridge readable standalone, at the cost of a little duplication in the payload shape. The primitives are the part where duplication would actually be dangerous (a divergent matcher or exit-code rule is a correctness bug); the payload is the part where explicitness beats sharing. + +## Consequences + +The two bridges (PR-F) become thin: parse the config file, pick a matcher mode, build the per-event payload+env, call `runHook` + `mergeHookOutputs`, map the outcome to a Decision, and append `hook/*`. The protocol's correctness-critical halves (matcher semantics, exit-code contract, merge precedence) live in one tested place — `hook-protocol` ships with heavy unit tests (matcher per-mode, codec per exit-code/field, runner plumbing with a stub executor, merge precedence, the `hook/*` helpers) at per-file 100%. Input rewrite (`updatedInput`) is parsed but not honored (the deferred [pre-tool-input-rewrite RFC](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md)); a bridge logs+warns on it.

Codex's PR-E review found three protocol-fidelity blockers + two doc gaps, all verified against ~/repos/refs: - (A) Top-level `decision` accepted allow/deny/ask, but both reference schemas reserve those for hookSpecificOutput.permissionDecision — the legacy top-level decision is approve/block ONLY. Split topLevelDecisionOf (approve/block) from permissionDecisionOf (allow/deny/ask), so an out-of-band {"decision":"deny"} is now invalid and ignored instead of becoming a real blocking decision. - (A) hookSpecificOutput was parsed without its hookEventName discriminator. HookOutput now surfaces hookEventName so a bridge can discard a block whose claimed event doesn't match the firing one (the schemas key the block by event). - (A) runHook discarded raw stdout. HookOutput now carries `stdout` (trimmed, verbatim) so a bridge can reproduce CC's plain-stdout rendering / Codex's plain-stdout-as-additionalContext behavior. - (B) hook/* SessionEventMap variants were only named in prose; added a payload/role table to core-data-structures/session.md (a maintained catalog surface). - (B) Removed PR-stack-position references (PR-F / "future bridge packages") from a test comment and the RFC, per the current-state-wording rule.

The package is a library, so it has no `cordis.yml` load path of its own — its real-load-path coverage comes through the bridge plugins that consume it. diff --git a/packages/hooks/hook-protocol/src/codec.ts b/packages/hooks/hook-protocol/src/codec.ts index f6065af90e..ac49526600 100644 --- a/packages/hooks/hook-protocol/src/codec.ts +++ b/packages/hooks/hook-protocol/src/codec.ts @@ -42,14 +42,19 @@ function obj(value: unknown): Record | undefined { : undefined } -/** Normalize a raw `decision`/`permissionDecision` string to the neutral enum. */ -function decisionOf(value: string | undefined): HookOutput['decision'] { - switch (value) { - case 'approve': case 'allow': case 'block': case 'deny': case 'ask': - return value - default: - return undefined - } +/** + * The legacy TOP-LEVEL `decision` is only `approve`/`block` in both reference + * schemas — `allow`/`deny`/`ask` are reserved for `hookSpecificOutput. + * permissionDecision`.

A bridge is a faithfulness adapter, not a power tool: anything it does a native cordis plugin does more powerfully — the bridge exists only to run UNMODIFIED external hooks. - dsh-hooks-claude: CC dialect. Seven hook points (SessionStart, UserPromptSubmit, PreToolUse, PostToolUse, Stop, SubagentStart, SubagentStop), CC per-event stdin payloads, env + ${CLAUDE_PLUGIN_ROOT}/ ${CLAUDE_PROJECT_DIR} substitution, literal-or-regex matcher. - dsh-hooks-codex: Codex dialect — a deliberate subset. Five hook points, always-regex matcher, snake_case payloads (turn_id/model, no trailing newline), no env/substitution, block-only decisions. Both map the neutral merged outcome onto the seam's typed Decision and stamp an explicit {kind:'plugin'} source on injected context (so it is never mislabeled as a user prompt). Config parse-failure is contained; only command hooks run. updatedInput is logged+warned (input rewrite deferred); the Stop loop-guard is deferred (TODO). Tests: per-file 100% — config-parse unit branches + per-seam mappings end-to-end through the REAL loop + REAL bash + REAL shell scripts (scripted mock model only) + a real-Loader export-shape guard. A keyless ACP snapshot scenario (hook-prompt-block) proves a UserPromptSubmit hook blocks a prompt end-to-end (rejected turn -> ACP cancelled, hook/* events in the log); a with-key e2e (hooks.e2e.ts) proves a PreToolUse hook blocks real bash (verified on disk).

interception seams ([the interception-seams RFC](2026-06-30-interception-seams.md)): a "native hook" is just an ordinary cordis plugin subscribing to `agent/session-start`, `agent/prompt-submit`, `tools/pre-execute`, `tools/post-execute`, `agent/turn-continuation`, `subagent/start`, `subagent/end`. But users arrive with **existing** Claude Code (CC) and Codex hook configs — a `hooks.json` (or a settings file's `hooks` key) full of shell-command hooks — and want those to run unmodified. This RFC introduces the two **bridge plugins** that translate that external shell-hook protocol onto the typed seams, built on the shared wire-protocol library ([the hook-protocol-lib RFC](2026-06-30-hook-protocol-lib.md)). + +The framing that shapes the whole design: **a bridge is a faithfulness adapter, not a power tool.** Anything a bridge does (block a tool, inject context, force continuation, observe a subagent) a native cordis plugin does more powerfully — typed returns, full `ctx`, no serialization boundary. The bridge's only reason to exist is to run an UNMODIFIED external CC/Codex hook with byte-faithful semantics. That keeps each bridge thin: parse the config, pick a matcher mode, build the per-event payload, call `runHook` + `mergeHookOutputs` from the shared lib, map the neutral outcome onto a seam Decision. + +## Decision + +Two independent plugins in the `packages/hooks/` group, each a function/namespace plugin (`name`/`inject`/`Config`/`apply`, NO default export — see [postmortem 0001](../../../postmortem/0001-acp-default-export-drops-inject.md)) injecting only `bash`: + +- **`dsh-hooks-claude`** — the CC dialect. Seven hook points: `SessionStart`, `UserPromptSubmit`, `PreToolUse`, `PostToolUse`, `Stop`, `SubagentStart`, `SubagentStop`. Owns CC's per-event stdin payloads (a base of `session_id`/`cwd`/`hook_event_name` plus per-event fields), CC's env + `${CLAUDE_PLUGIN_ROOT}`/`${CLAUDE_PROJECT_DIR}` substitution, and the literal-or-regex matcher mode. A CC hook's stdin carries a **trailing newline**. +- **`dsh-hooks-codex`** — the Codex dialect: a deliberate SUBSET. Five hook points (`PreToolUse`, `PostToolUse`, `SessionStart`, `UserPromptSubmit`, `Stop` — no subagent/notification/compaction), an always-regex matcher, snake_case payloads with `turn_id`/`model`/`permission_mode` extras written WITHOUT a trailing newline, no env and no `${…}` substitution, and a block-only decision model (a Codex hook can never pre-approve, so `allow`/`ask` are not honored). Codex hardcodes a tool call's `tool_name` to `"Bash"` and `tool_input` to `{ command }`. + +### Outcome → Decision mapping + +Each bridge maps the neutral `MergedHookOutcome` from the shared lib onto the seam's typed Decision: + +| Seam | CC | Codex | +|---|---|---| +| `agent/session-start` (emit) | additionalContext → `agent.inject()` | plain-stdout output → additionalContext → `agent.inject()` | +| `agent/prompt-submit` | `deny`→`block`; context→`allow` | `block`→`block`; context→`allow` | +| `tools/pre-execute` | `deny`→`deny`; `ask`→`ask` | `block`→`deny` (no allow/ask) | +| `tools/post-execute` | `deny`→`block`+feedback; context→`accept` | same | +| `agent/turn-continuation` | blocking Stop → `continue` (reason = next-step steering) | same | +| `subagent/start` (emit) | additionalContext → inject into the live child | — (not a Codex event) | +| `subagent/end` (emit) | observe-only | — | + +### Context source is always the plugin (the mislabel guard) + +`agent.inject()` defaults a missing `MessageSource` to `{ kind: 'user' }` — which would record plugin-injected context as if the user had typed it. So every bridge `inject()` and every `HookContext` passes an explicit `{ kind: 'plugin', plugin: 'hooks-claude' | 'hooks-codex' }` source. A test asserts the resulting `context/message.source` is the plugin, never `user`. + +### Containment + +The config is parsed ONCE at load; a read/parse failure logs and registers nothing rather than crashing boot (a typo'd path must not take the agent down). Only `type: 'command'` hooks run — a `prompt`/`agent`/HTTP hook (CC) or an `async: true` / non-command hook (Codex) is parsed-and-skipped with a warning. The emit-listener paths (`session-start`, `subagent/start`) run detached, with their `inject` contained in a `.catch` that logs (a throwing inject must not break session boot or the loop). + +## Deferred (faithful-but-degraded) + +- **Tool-input rewrite.** A CC/Codex `updatedInput` is logged + warned, not honored — input rewrite is a deferred consistency-design problem ([the pre-tool-input-rewrite RFC](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md)), because the pre-execution args are read by `tool/call` audit + `assistant/message` history + ACP/tool-bash presentation, so an honest rewrite is a design unit, not a field. +- **Stop loop-guard** (`TODO(stop-loop-guard)`). CC/Codex break an infinite force-continue with `stop_hook_active` (true once a Stop hook fired this run) plus a max-consecutive cap; both are deferred. Today `stop_hook_active` is always `false`, so a Stop hook that unconditionally blocks would force-continue every step — a hook author must self-limit until the guard lands. +- **Permission `ask`** degrades to `deny` at the `tools/pre-execute` seam (`FIXME(permissions)` in the interception-seams RFC) — there is no interactive permission prompt yet. +- **Config discovery.** The path is explicit in `cordis.yml`; the full multi-layer CC/Codex precedence walk and the trust/hash model are not reimplemented (`TODO`). + +## Consequences + +The bridges are thin and readable standalone: the correctness-critical halves (matcher semantics, exit-code contract, merge precedence) live in the shared `dsh-hook-protocol`, so each bridge is just config-parse + payload-build + outcome-map. Each is covered at per-file 100% — config-parse branches as unit tests, and the seam mappings end-to-end through the REAL loop + REAL `dsh-bash-local` + REAL shell scripts from a temp `hooks.json` (a scripted mock MODEL is the only stand-in), plus a real-Loader export-shape guard so a stray default export can't silently drop `inject`. Because the seams already carry typed Decisions, a future native plugin needs none of this bridge machinery — it returns a Decision directly. diff --git a/examples/AGENTS.md b/examples/AGENTS.md index c104c2cd8e..903f59781c 100644 --- a/examples/AGENTS.md +++ b/examples/AGENTS.md @@ -21,6 +21,6 @@ A keyless smoke that spawns the example from a temp cwd must set `TSX_TSCONFIG_P |---|---|---| | `echo-agent` | `tests/echo.e2e.ts` — boots the real `cordis.yml`, drives the echo tool round-trip and the direct canned reply | **N/A — keyless by nature** (the `mock-echo` model has no real provider) | | `coding-agent` | `tests/keyless-smoke.e2e.ts` — boots the full real tree (dummy key, no prompt → no model call), asserts banner + clean exit | `tests/{full-loop,coding-task,resume,todo-write}.e2e.ts` — real model + real bash + real todo_write, world-verified | -| `acp-agent` | `pnpm run test:snapshot` — boots the real ACP subprocess and replays a recorded session keyless; `tests/acp.e2e.ts` also asserts stdout purity without a key | `tests/acp.e2e.ts` — real ACP prompt, verifies a file the agent wrote | +| `acp-agent` | `pnpm run test:snapshot` — boots the real ACP subprocess and replays a recorded session keyless (incl. `hook-prompt-block`, where a `UserPromptSubmit` hook blocks the prompt); `tests/acp.e2e.ts` also asserts stdout purity without a key | `tests/acp.e2e.ts` — real ACP prompt, verifies a file the agent wrote; `tests/hooks.e2e.ts` — a real `PreToolUse` hook blocks bash, verifies the file is NOT written | See [the root AGENTS.md](../AGENTS.md) for repo-wide conventions and [docs/architecture.md](../docs/architecture.md) for the design. diff --git a/examples/acp-agent/cordis.snapshot.yml b/examples/acp-agent/cordis.snapshot.yml index 90c8dd2daf..fc7d81298b 100644 --- a/examples/acp-agent/cordis.snapshot.yml +++ b/examples/acp-agent/cordis.snapshot.yml @@ -83,3 +83,13 @@ # replayed todo_write tool call resolves to a real tool during snapshot replay. - id: tool-todo name: '@deepseek-ai/dsh-tool-todo' + +# The Claude Code hook bridge, pointed at a `hooks.json` in the session cwd.

charset=UTF-8 Content-Transfer-Encoding: 8bit The reference schemas key the `hookSpecificOutput` block by `hookEventName`, so a block naming a DIFFERENT event than the one firing is malformed — a hook emitting `hookSpecificOutput.hookEventName: "PreToolUse"` on a `Stop` event must not deny the Stop. The codec surfaced `hookEventName` for a bridge to compare but never enforced the discard, so both bridges pushed every parsed output into the merge unconditionally. parseHookOutput now takes an optional `expectedEventName`; when the block's `hookEventName` names a different event, its event-scoped fields (permissionDecision/permissionDecisionReason/additionalContext/updatedInput) are discarded (the discriminator is still surfaced for the log, and the event-agnostic top-level decision/continue/etc. are unaffected). runHook threads it via RunHookOptions.expectedEventName; a caller that omits it opts out.

Force-continue on any deny; fall back to a generic steering line when there is no reason. - Codex payload tool_name: hardcoded "Bash" disagreed with the exec.name matcher subject, so a real Codex `matcher:"Bash"` never fired against the harness's lowercase `bash` tool. Use exec.name in both payload builders (matches the matcher subject and the sibling CC bridge). Doc/RFC updated. - Codex plain-stdout context: SessionStart/UserPromptSubmit are documented to treat a clean hook's PLAIN (non-JSON) stdout as additionalContext, but nothing folded it. runPoint now folds plain stdout into context for those two events, gated on the codec's JSON gate so structured stdout is never dumped as prose. - continue:false is deferred, not honored: the seams have no hard-halt primitive yet. TODO(hook-continue-false) at both bridges + an RFC deferred note; the two tests now assert the LOG records the halt request AND that the run is NOT actually halted (no longer misleading). - README concurrency wording: hooks run SERIALLY (deliberate — adjacent invoked/result log pairs, order-independent fold), not concurrently. Fixed the CC README claim + an RFC note. Regression guards proven red on the unfixed code, then reverted.

These bridges run them **serially** (`await` per hook inside the match loop) and fold with the same most-restrictive merge. Serial is deliberate: it keeps each hook's `hook/invoked`/`hook/result` pair adjacent and in a deterministic order in the session log, and the fold is order-independent for the decision (`deny > ask > allow`) so the outcome matches. The cost is latency (hook *N* waits for hook *N−1*) and that per-hook timeouts are not overlapped — acceptable for the hook counts real configs use; revisit if a config ever fans out enough for the wall-clock to matter. + ## Consequences The bridges are thin and readable standalone: the correctness-critical halves (matcher semantics, exit-code contract, merge precedence) live in the shared `dsh-hook-protocol`, so each bridge is just config-parse + payload-build + outcome-map. Each is covered at per-file 100% — config-parse branches as unit tests, and the seam mappings end-to-end through the REAL loop + REAL `dsh-bash-local` + REAL shell scripts from a temp `hooks.json` (a scripted mock MODEL is the only stand-in), plus a real-Loader export-shape guard so a stray default export can't silently drop `inject`. Because the seams already carry typed Decisions, a future native plugin needs none of this bridge machinery — it returns a Decision directly. diff --git a/packages/hooks/hooks-claude/README.md b/packages/hooks/hooks-claude/README.md index 02cdfc9894..126573c6be 100644 --- a/packages/hooks/hooks-claude/README.md +++ b/packages/hooks/hooks-claude/README.md @@ -39,7 +39,7 @@ The config is parsed **once** at load.

Gate the fold on `output.exitCode === 0`, matching the codec's own structured-stdout rule. Guard tests for both paths, proven red without the gate. - (B) The Codex "SessionStart no-context no-op" absence test was unsound (a completed turn doesn't prove the detached hook finished). It now touches a marker and waitFor()s it before asserting no context. - (B) Both HMR tests used a no-op `true` hook, so a leaked listener would still pass. They now use a BLOCKING (exit 2) UserPromptSubmit hook and assert the post-dispose turn is NOT blocked and logs no hook/invoked — a leaked listener fails loudly. --- .../hooks/hooks-claude/tests/bridge.spec.ts | 22 +++++++--- packages/hooks/hooks-codex/src/index.ts | 14 ++++--- .../hooks/hooks-codex/tests/bridge.spec.ts | 12 ++++-- .../hooks/hooks-codex/tests/coverage.spec.ts | 40 +++++++++++++++++-- 4 files changed, 72 insertions(+), 16 deletions(-) diff --git a/packages/hooks/hooks-claude/tests/bridge.spec.ts b/packages/hooks/hooks-claude/tests/bridge.spec.ts index 0cc4458f52..0b6afd7e4c 100644 --- a/packages/hooks/hooks-claude/tests/bridge.spec.ts +++ b/packages/hooks/hooks-claude/tests/bridge.spec.ts @@ -322,17 +322,29 @@ describe('hooks-claude bridge — load resilience', () => { }) it('disposing the bridge fiber removes its listeners (HMR safety)', async () => { - const dir = writeConfig({ UserPromptSubmit: [{ hooks: [{ type: 'command', command: 'true' }] }] }) + // A BLOCKING UserPromptSubmit hook: if the listener leaked past dispose it + // would veto the prompt (0 model requests) and log a hook/invoked.

Both bridges now thread the agent's session `header.cwd` (the session/new.cwd) as the hook workdir for agent-scoped points. Regression per bridge: server cwd ≠ session cwd, a `pwd` hook proves it ran in the session workspace (proven red without the workdir). - Example config honesty (blocking): `configPath: ./hooks.json` is read ONCE at load against the PROCESS cwd, not per-session — the comment/README now say so explicitly (a project-local per-session hooks.json is not discovered; TODO(per-session-hook-config)). The hooks-run-in-session-cwd fix above is the distinct, separately-documented half. - Session-start timing (blocking): agent/session-start is a synchronous emit and the hook runs on a detached .then, so injected context is BEST-EFFORT — not guaranteed before the first request. Downgrade the contract in code comments + README + RFC (TODO(session-start-gating)) rather than implying "first request sees it", and add a no-wait regression that asserts the safe properties without pre-waiting for the inject. - systemMessage (non-blocking): the merge collects merged.systemMessages but no bridge surfaced it. Warn per hook (like updatedInput) and document it as deferred in both READMEs + the RFC; tests assert the warn + non-surfacing. --- .../feature/2026-06-30-hook-bridges.md | 7 +- examples/acp-agent/cordis.snapshot.yml | 13 ++-- examples/acp-agent/cordis.yml | 15 ++-- packages/hooks/hooks-claude/README.md | 5 +- packages/hooks/hooks-claude/src/index.ts | 27 ++++++- .../hooks/hooks-claude/tests/coverage.spec.ts | 76 +++++++++++++++++++ packages/hooks/hooks-codex/README.md | 6 +- packages/hooks/hooks-codex/src/index.ts | 19 ++++- .../hooks/hooks-codex/tests/coverage.spec.ts | 37 +++++++++ 9 files changed, 189 insertions(+), 16 deletions(-) diff --git a/docs/rfc/implemented/feature/2026-06-30-hook-bridges.md b/docs/rfc/implemented/feature/2026-06-30-hook-bridges.md index 1e782f9b67..d6aea68b17 100644 --- a/docs/rfc/implemented/feature/2026-06-30-hook-bridges.md +++ b/docs/rfc/implemented/feature/2026-06-30-hook-bridges.md @@ -39,13 +39,18 @@ Each bridge maps the neutral `MergedHookOutcome` from the shared lib onto the se The config is parsed ONCE at load; a read/parse failure logs and registers nothing rather than crashing boot (a typo'd path must not take the agent down).

The hooks **themselves** run in the agent's **session workspace**: for the agent-scoped points the bridge threads the session's `cwd` (`session/new.cwd`, on the session header) to `runHook` as the process working directory, so a hook's `pwd` / relative-file read / marker write operates in the user's project tree, not the server's launch directory. The **config path**, by contrast, is **process-level**: `configPath` is resolved and parsed once at load against the process launch cwd, so a single `hooks.json` applies to the whole process — there is no per-session config discovery that reads a project-local `hooks.json` from each `session/new.cwd` (`TODO(per-session-hook-config)`).

CC/Codex break an infinite force-continue with `stop_hook_active` (true once a Stop hook fired this run) plus a max-consecutive cap; both are deferred. Today `stop_hook_active` is always `false`, so a Stop hook that unconditionally blocks would force-continue every step — a hook author must self-limit until the guard lands. - **Permission `ask`** degrades to `deny` at the `tools/pre-execute` seam (`FIXME(permissions)` in the interception-seams RFC) — there is no interactive permission prompt yet. - **Hook `continue:false` (hard halt).** A hook can ask to halt the whole run (CC/Codex `continue:false`); the shared merge folds it into `MergedHookOutcome.stop`/`stopReason`, but no bridge acts on it (`TODO(hook-continue-false)`) — the interception seams have no "hard-halt the agent" primitive yet (a Decision blocks/steers a single point, not the run). Deferred with the loop-guard work; the halt request is recorded in the `hook/result` log, and the hook keeps its per-point effect (decision/context) meanwhile. -- **Config discovery.** The path is explicit in `cordis.yml`; the full multi-layer CC/Codex precedence walk and the trust/hash model are not reimplemented (`TODO`). +- **Config discovery.** The path is explicit in `cordis.yml` and process-level (see above); the full multi-layer CC/Codex precedence walk, per-session project-local discovery, and the trust/hash model are not reimplemented (`TODO(per-session-hook-config)`). +- **Session-start / subagent-start context is best-effort, not gated (`TODO(session-start-gating)`).** `agent/session-start` is a synchronous emit and the bridge runs its hook on a detached `.then`, so the injected `additionalContext` is not guaranteed to land before the first turn reaches the model — a slow hook can miss the first request (the context then arrives as a later injection). `subagent/start` is sharper: an in-process provider may have already queued the child's prompt before the listener runs, and a short-lived child can finish before the detached inject fires. Making startup context a gated/awaited primitive is a loop-level change deferred to the interception seams; today the contract is "injected as soon as the hook resolves", not "before the first request".

Turn and step boundaries are now read exclusively off the durable `session/event` feed (`turn/start`/`turn/end`/`step/start`/`step/end`) — there is no `agent/*` mirror for any boundary. - loop.ts: delete both turn emits; `closeTurn` loses its `emit` parameter and its now-unreachable idempotency guard (it is called exactly once per turn, on mutually exclusive normal/catch paths); `failTurn` loses the dead post-close branch that only a throwing turn-end LISTENER could reach. - ui-stdio: render turn boundaries from `session/event`, recovering the short agent label from an `agent/created`→id map (the `turn/start` event carries only the turn number, and the session id is not reliably the agent id). ui-stdio is a disposable test REPL, so this migration retires the sole justification the event-domain-semantics RFC gave for KEEPING the turn mirrors. - Tests: reason/turn-number collectors and the boundary-ordering test now read `session/event`; the throwing-turn-boundary-LISTENER tests are deleted (that code path no longer exists). A new test covers the outer-catch disposed branch via a pre-step listener that disposes-then-throws (the surviving real path). - Docs: promote the "remove agent boundary mirror events" RFC to implemented (amended/narrowed — `agent/steering` is RETAINED, not a boundary mirror); update the event-domain-semantics + turn-enclosure RFCs, architecture.md, the cookbook, the ACP/agent/ui-stdio prose, and regenerate the cordis catalog. `agent/steering` and `agent/stream-chunk` are explicitly out of scope (not durable-boundary mirrors). ACP is unaffected — it already settles from the log's `turn/end` + `agent/status`; snapshot goldens are byte-unchanged. --- docs/architecture.md | 8 +- docs/cookbook/extension-cookbook.md | 2 +- docs/cordis-catalog/events-and-services.md | 46 +--- docs/rfc/README.md | 2 +- .../2026-06-15-turn-enclosure-invariant.md | 2 +- .../2026-06-30-event-domain-semantics.md | 16 +- ...-20-remove-agent-boundary-mirror-events.md | 37 ++++ ...-20-remove-agent-boundary-mirror-events.md | 31 --- packages/core/agent-loop/src/loop.ts | 73 +++---- packages/core/agent-loop/tests/cancel.spec.ts | 27 ++- .../agent-loop/tests/coverage-edges.spec.ts | 71 +----- packages/core/agent-loop/tests/loop.spec.ts | 33 ++- .../agent-loop/tests/review-fixes.spec.ts | 205 +++++------------- packages/core/agent/README.md | 6 +- packages/core/agent/src/types.ts | 38 +--- packages/support/ui-stdio/README.md | 7 +- packages/support/ui-stdio/src/index.ts | 33 ++- .../support/ui-stdio/tests/ui-stdio.spec.ts | 52 ++++- packages/ui/acp/README.md | 2 +- packages/ui/acp/src/index.ts | 32 +-- 20 files changed, 282 insertions(+), 441 deletions(-) create mode 100644 docs/rfc/implemented/simplification/2026-06-20-remove-agent-boundary-mirror-events.md delete mode 100644 docs/rfc/proposed/simplification/2026-06-20-remove-agent-boundary-mirror-events.md diff --git a/docs/architecture.md b/docs/architecture.md index da6641440d..8f83625ab0 100644 --- a/docs/architecture.md +++ b/docs/architecture.md @@ -159,7 +159,7 @@ forever: steering pending forces cont = true (from continuation listeners OR from step/end session-event listeners — the /goal pattern; hasSteering override) if !cont: break - session('turn/end'); emit agent/turn-end + session('turn/end') ⟵ durable turn boundary (no agent/* mirror) await ctx.parallel('session/flush', session) ⟵ durability checkpoint (failure reported via agent/error, not fatal) leftover steering re-enqueued as queued messages ⟵ steering is never stranded @@ -170,7 +170,7 @@ Error containment: a throwing `agent/turn-continuation` listener or a broken ste Turn-end reasons: a turn ends with one `TurnEndReason` — `completed`, `aborted`, `error`, `disposed`, or `max-tokens`. `max-tokens` mirrors the model-call `FinishReason` of the same name (DeepSeek's `length`): a step that hit the output-token ceiling makes the turn end `max-tokens` rather than `completed`, by the rule *any `max-tokens` step in the turn surfaces as `max-tokens`* (a continuation plugin may run further steps after one, but the cut-short fact wins; the `disposed`/`aborted`/`error` outcomes still take precedence).

Per [AGENTS.md "tests document behavior, not golden truth"](../../../../AGENTS.md), the behavior and its test moved (or died) together. - The loop marks the step open (`stepOpen = true`) BEFORE appending `step/start`, because `Session.append` pushes the event to the log before notifying `session/event` listeners (validation throws happen earlier, before the push — see [the session append contract](../../../core-data-structures/session.md)). So a throwing `step/start` session-event listener runs with the step already open and the event already in the log: the loop's outer catch then calls `closeStep()`, which appends the balancing `step/end`, and the turn closes balanced with an error (`turn/start → step/start → step/end → turn/end` — verified by the invariants oracle in the regression test). Closing the open step is owed precisely because the marker is set first. -- This is a partial, conservative realization of the broader [proposed simplification "Stop mirroring durable boundaries as agent events"](../../proposed/simplification/2026-06-20-remove-agent-boundary-mirror-events.md): that RFC proposes removing ALL boundary mirrors (including the turn boundaries and `agent/steering`) and migrating the stdio UI's turn rendering onto `session/event`.

Connection plus `initialize`/`session/new`: wire `AgentSideConnection` to stdin/stdout; protocolVersion negotiation; the single-session guard; create the live session through the new `{ sessionId, meta }` factory seam (so the ACP `sessionId` and validated `cwd` become the session's id and header); the `sessionId↔agent` and `Session↔sessionId` maps. 3. Internal edit — turn-end reason fidelity (sanctioned: edit internals to fit ACP). Extend `TurnEndReasonMap` in the proper places: (a) declaration-merge a `max-tokens` variant in the owning package (`packages/core/session/src/types.ts`, alongside `completed|aborted|error|disposed`) — add `max-tokens` because `FinishReasonMap` produces it (DeepSeek maps `length` → `max-tokens`); do not add `refusal`, since no current adapter produces it (unknown DeepSeek finish reasons collapse to `error`), but leave a comment in `TurnEndReasonMap` noting `refusal` should be added when an adapter first emits it (`FinishReasonMap` is merge-extensible); (b) make `agent-loop`'s `loop.ts` populate the reason from the model `finish` chunk — `assembler.finish` lives inside `runStep`, so `runStep` must return it up to `runTurn`, and the rule is "the last step's finish reason wins, but any `max-tokens` in the turn surfaces as `max-tokens`"; (c) no consumer exhaustively switches over `TurnEndReason` today (the invariants plugin switches on `SessionEventType`, and `deriveMessages` ignores `turn/end`), so adding `max-tokens` is a non-breaking extension — but recheck before landing; (d) update [docs/architecture.md](../../../architecture.md) (the CI-verified loop-lifecycle/event-taxonomy doc) and the affected package READMEs/JSDoc (`dsh-session`, `dsh-agent`, `dsh-agent-loop`) per the repo doc-sync policy. This replaces a fragile "observe the finish chunk in the bridge" hack with a real, documented contract. -4. Prompt-turn streaming plus load: translate `agent/stream-chunk` and `session/event` into `session/update`; resolve `session/prompt` on settle, mapping the harness `TurnEndReason` to the ACP `StopReason` wire enum (`completed`→`end_turn`, `max-tokens`→`max_tokens`, `aborted`→`cancelled`) — a small total function with a test asserting the exact wire strings, since the SDK rejects an unknown `stopReason`. Concrete correlation, since the loop batches queued messages into one turn and `send()` does not synchronously flip to running: install listeners before `send()`; gate on an observed `agent/turn-start` (confirms work was accepted) then resolve on the next `agent/turn-end`; reject an empty/whitespace prompt up front rather than calling `send()` (no turn would ever start, so the RPC would hang).

Implement `session/load` on the session-persistence resume seam. 5. Permission gate: a single `tools/execute` listener registered with `prepend: true`, owning a `WeakMap` of bridge-created agents; no-op (`next()`) for unowned/no-agent calls; for owned calls → `session/request_permission` → allow (`next()`) / veto; settle the stored resolver exactly once on outcome, cancel, or connection close. 6. Example wiring (extract a shared base). `@cordisjs/plugin-include` is itself a plugin entry that resets `ctx.baseUrl` and loads a path, so a child `cordis.yml` can nest-include a shared base; the extraction is safe because every dependent plugin declares `inject` (loader groups initialize via `Promise.all`, so YAML order is NOT the dependency mechanism — never rely on it). Extract the provider/tool core (`llm, sessions, system-prompt, tools, agents, invariants, llm-deepseek, bash-local, tool-bash`) into `examples/base.yml`; have both `coding-agent` and a new `examples/acp-agent/` include it and add their own UI plugin plus logger. Keep `agent-loop` per-example (NOT in the base): `AgentLoop` creates its configured agents in its constructor, and the two examples disagree — `coding-agent` needs a pre-created `main` (its `stdio-chat` calls `ctx.agents.get('main')`), while `acp-agent` must pre-create none (ACP `session/new` creates agents). So `coding-agent` declares `agent-loop` with `agents: [{ id: main, … }]` and `acp-agent` with `agents: []`. `acp-agent` loads `dsh-session-persistence-jsonl` (from [session persistence](../../implemented/architecture/2026-06-14-session-persistence.md) — required for `session/load`), omits the stdout logger (see Risks), and adds `pnpm run demo:acp` plus the Zed `agent_servers` snippet. 7. Tests (the repo cares a lot here): a property-based test for the protocol shape (precedent: [property-based testing](../../implemented/testing/2026-06-11-property-based-testing.md)) — fuzz arbitrary harness event sequences and assert ACP-stream invariants (never a `tool_call_update` before its `tool_call`; exactly one `session/prompt` resolution per prompt; monotonic, well-formed ordering; `stopReason` in the legal set); codec unit tests over an in-memory `Duplex` pair (drive `AgentSideConnection` without a subprocess; assert exact frames for `initialize`, `session/new`, a full prompt turn); the mandatory HMR-safety test (dispose the fiber; assert the connection closed, all `ctx.on` listeners gone, any in-flight `request_permission` settled); failure-path tests (connection closes mid-stream; closes with a permission pending; a notification `send()` rejects but the turn survives; `finish{kind:'error'|'aborted'}`; a `tools/execute` throw with no `tool/result`; a second `session/new` rejected; a `session/prompt` while one is in flight; an empty prompt rejected without hanging; a `session/load` re-derives identical history and replays it); and an e2e (`*.e2e.ts`, self-skips without `DEEPSEEK_API_KEY`) that boots `examples/acp-agent`, connects a `ClientSideConnection`, sends a real prompt, owns and disposes the harness in `afterEach`, and verifies the world (files on disk), not the agent's self-report. diff --git a/packages/core/agent-loop/src/loop.ts b/packages/core/agent-loop/src/loop.ts index eba75f9615..3921122559 100644 --- a/packages/core/agent-loop/src/loop.ts +++ b/packages/core/agent-loop/src/loop.ts @@ -529,11 +529,14 @@ async function runTurn(ctx: Context, agent: ReactLoopAgent, handle: LoopHandle, // Gating on a "turn started" boolean would skip turn/end and leave a // permanently OPEN turn that poisons the next turn/replay (the turn-enclosure RFC).

A model driving the `bash` tool already has equivalent power to set env vars and feed stdin through ordinary shell syntax (`FOO=bar cmd`, heredocs), so the `env`/`stdin` seam fields grant it no new capability — and they cannot exfiltrate the harness's ambient credentials, because the credential SCRUB in dsh-bash-local (which strips *KEY*/*SECRET*/*TOKEN* from process.env before the child sees it) is the actual control, and it works regardless of these fields (tool-call args are static JSON, never shell-evaluated). So drop the "dangerous / trusted-plugin boundary" language across the RFC, the three bash-package READMEs, the bash/src/types.ts JSDoc, and docs/bash.md (both the type-equiv blocks — kept 1:1 with source — and the prose). The reality that remains: the `bash` tool doesn't EXPOSE env/stdin as parameters because they'd be redundant with shell syntax; the fields exist for in-process plugins (the hooks bridges) to pass a JSON payload + CLAUDE_* vars cleanly. The guard test is kept but reframed: it catches a future `...args` spread that would silently forward model input into the post-scrub env merge, NOT a trust wall.

Rather than let a foreign concept sit on the core seam, remove it: - `SubagentStartRequest`, `SubagentRunInfo`, `SubagentRunEndInfo`: drop the `agentType` field; the `subagent/start`/`subagent/end` payloads now carry `provider`/`id` (+ end `stopReason`/`lastAssistantMessage`) only. - `dsh-tool-subagent`: drop `Config.agentType` and its request plumbing. - Tests: keep the lastAssistantMessage / clone-containment / reject-path coverage (rewritten to not assert agentType); delete the two tool-subagent tests that only exercised agentType forwarding (dead behavior). - Docs: retitle + rewrite the subagent-observe-enrich RFC to the one shipped enrichment (lastAssistantMessage), with a note on why agentType was dropped; update rfc/README index title, both subagent READMEs, and the core-data-structures/subagent.md type-equiv block + prose; regenerate catalog. The CC bridge (PR-F) will feed Claude Code's own default matcher value "general-purpose" for its SubagentStart/Stop agent_type matcher instead. --- docs/cordis-catalog/events-and-services.md | 2 +- docs/core-data-structures/subagent.md | 3 +- docs/rfc/README.md | 2 +- .../2026-06-30-subagent-observe-enrich.md | 21 ++++---- packages/subagent/subagent/README.md | 2 +- packages/subagent/subagent/src/index.ts | 24 +++------ packages/subagent/subagent/src/types.ts | 9 ---- .../subagent/subagent/tests/service.spec.ts | 39 +++----------- packages/subagent/tool-subagent/README.md | 1 - packages/subagent/tool-subagent/src/index.ts | 10 ---- .../tool-subagent/tests/tool-subagent.spec.ts | 54 ------------------- 11 files changed, 29 insertions(+), 138 deletions(-) diff --git a/docs/cordis-catalog/events-and-services.md b/docs/cordis-catalog/events-and-services.md index e6dd0881fa..ae549af20f 100644 --- a/docs/cordis-catalog/events-and-services.md +++ b/docs/cordis-catalog/events-and-services.md @@ -445,7 +445,7 @@ list(): string[] start(name: string, request: SubagentStartRequest): SubagentRun ``` -Source: [`packages/subagent/subagent/src/index.ts:130`](../../packages/subagent/subagent/src/index.ts) +Source: [`packages/subagent/subagent/src/index.ts:121`](../../packages/subagent/subagent/src/index.ts) ### `ctx.systemPrompt` — `SystemPrompt` diff --git a/docs/core-data-structures/subagent.md b/docs/core-data-structures/subagent.md index ca85830808..1d998b60b7 100644 --- a/docs/core-data-structures/subagent.md +++ b/docs/core-data-structures/subagent.md @@ -25,7 +25,6 @@ What a caller asks for when starting a subagent.

Replaced both with a single `subagentPayload()` built from `base(child)` (the child's session_id/cwd when the child is available) + `agent_id` + `agent_type` (+ `stop_hook_active` on Stop). - **SubagentStop runs in the child cwd**: the listener called `runPoint(..., {})` with no agent, so the hook ran in the executor/server cwd. It now looks the child up via `ctx.get('agents').get(info.id)` — still recoverable because `subagent/end` fires from the service's detached `.then` BEFORE the tool caller disposes the child — and passes `{ agent: child }`, matching SubagentStart. New regression: server cwd ≠ child cwd, a `pwd` SubagentStop hook proves it ran in the CHILD workspace (proven red by neutering the lookup). - **agent_type is a constant**: `info.agentType` no longer exists (removed on the subagent branch); both points now report the `SUBAGENT_TYPE = "general-purpose"` constant (Claude Code's Task-tool default), so a hooks.json default/`*`/empty `agent_type` matcher fires. Updated the README matcher-subject note and the bridge/coverage tests (dropped their agentType emits). - **e2e comment**: hooks.e2e.ts said `./hooks.json` loads from the session cwd; corrected to process-level (server launch cwd), with the hook itself running in the session cwd. --- examples/acp-agent/tests/hooks.e2e.ts | 11 ++-- packages/hooks/hooks-claude/README.md | 2 +- packages/hooks/hooks-claude/src/index.ts | 46 +++++++++++++---- .../hooks/hooks-claude/tests/bridge.spec.ts | 4 +- .../hooks/hooks-claude/tests/coverage.spec.ts | 51 ++++++++++++++++--- 5 files changed, 89 insertions(+), 25 deletions(-) diff --git a/examples/acp-agent/tests/hooks.e2e.ts b/examples/acp-agent/tests/hooks.e2e.ts index 19a80df03c..40a8d37457 100644 --- a/examples/acp-agent/tests/hooks.e2e.ts +++ b/examples/acp-agent/tests/hooks.e2e.ts @@ -19,11 +19,14 @@ import { /** * With-key e2e: the Claude Code hook bridge running against the REAL acp-agent * subprocess and the REAL model.

That is NOT observationally equivalent to the pre-seam `'ignore'` default — node's spawn pipe is an AF_UNIX socket, so `test -c /dev/stdin` (and any fd-0 type probe) flipped for every model-driven bash call, even though the code claimed the no-stdin path was unchanged. Spawn stdin as `'pipe'` only when the caller supplies bytes; otherwise `'ignore'` (fd 0 → /dev/null), the exact prior default. A literal `stdio` tuple per branch preserves the typed `spawn` overload's non-null stdout/stderr.

This distinction is observable and deliberate: a closed empty pipe and `/dev/null` are NOT the same file type (node's spawn pipe is an `AF_UNIX` socket, so `test -c /dev/stdin` holds for `/dev/null` but not for an empty pipe), so the no-stdin path — every model-driven call — must keep `/dev/null` rather than regress to an always-open pipe.

ESRCH is tolerated; daemons that re-parent away from the group can still survive — same caveat as the surveyed tools. - **Tail-keep truncation + spill files** — output beyond `maxOutputBytes` keeps the in-memory TAIL (errors/results cluster at the end — pi/OpenCode rationale) while the FULL stream is appended to a temp file whose path is reported when available.

In a MIXED batch — one queued prompt blocked, another allowed — the turn does not end `rejected`, so the blocked prompt and its reason vanished from the session log entirely. Add a `prompt/blocked` SessionEventMap variant (content + source + reason), appended in the open turn at the veto point in place of the user/message the prompt would have become. It is a non-surface, turn-enclosed event (like todo/write): it never reaches deriveMessages(). The fully-blocked batch still also ends `rejected` for boundary balance + ACP settlement. Regression test drives a mixed batch and asserts the blocked prompt is recorded while the allowed one runs — proven red without the append. --- docs/cordis-catalog/events-and-services.md | 26 +++++------ docs/core-data-structures/core.md | 2 +- docs/core-data-structures/session.md | 11 +++++ .../feature/2026-06-30-interception-seams.md | 4 +- packages/core/agent-loop/README.md | 2 +- packages/core/agent-loop/src/loop.ts | 8 ++++ .../agent-loop/tests/interception.spec.ts | 45 +++++++++++++++++++ packages/core/agent/src/types.ts | 12 +++-- packages/core/session/README.md | 2 +- packages/core/session/src/types.ts | 11 +++++ 10 files changed, 101 insertions(+), 22 deletions(-) diff --git a/docs/cordis-catalog/events-and-services.md b/docs/cordis-catalog/events-and-services.md index dc4b91f6b3..282e161235 100644 --- a/docs/cordis-catalog/events-and-services.md +++ b/docs/cordis-catalog/events-and-services.md @@ -25,7 +25,7 @@ An agent was registered in the AgentRegistry and is ready to receive messages.

A block with NO `hookEventName` slipped through and applied its event-scoped permission fields to whatever event was firing. Under the keyed Claude Code schema (where `hookEventName` is part of the block) a missing discriminator is as malformed as a mismatched one — a Stop/UserPromptSubmit hook emitting a bare `{ permissionDecision: 'deny' }` could deny the current point. Drop the `eventName !== undefined` clause so the guard fires on both a mismatch and an omission when the caller passes `expectedEventName`; the opt-out (no expectedEventName) still applies a discriminator-less block as-is.

charset=UTF-8 Content-Transfer-Encoding: 8bit Codex convergence findings on the delegate-and-fold fix (code path verified correct, prose only): - The hook-bridges RFC claimed a downstream `block` "carries the bridge context too" for BOTH seams. True for `tools/post-execute` (PostToolDecision.block has an additionalContext field) but false for `agent/prompt-submit` (PromptDecision.block is `{kind,reason}` with no context field). The code is already correct — a blocked prompt drops the context, which is right since the prompt never reaches the model. Reworded the RFC to state the per-seam difference accurately. - Two test comments narrated "Before the fix…", which the current-state-only doc rule forbids. Reworded to describe the behavior, not its history. - Documented on concatContext (both bridges) why the merged block carries a single source: a HookContext holds one MessageSource and the seam cannot represent mixed provenance; rendering distinguishes only by source.kind, so a downstream plugin's text stays framed as plugin context. --- docs/rfc/implemented/feature/2026-06-30-hook-bridges.md | 2 +- packages/hooks/hooks-claude/src/index.ts | 7 ++++++- packages/hooks/hooks-claude/tests/coverage.spec.ts | 2 +- packages/hooks/hooks-codex/src/index.ts | 6 +++++- packages/hooks/hooks-codex/tests/coverage.spec.ts | 4 ++-- 5 files changed, 15 insertions(+), 6 deletions(-) diff --git a/docs/rfc/implemented/feature/2026-06-30-hook-bridges.md b/docs/rfc/implemented/feature/2026-06-30-hook-bridges.md index a8cc3df4db..3bedd73b34 100644 --- a/docs/rfc/implemented/feature/2026-06-30-hook-bridges.md +++ b/docs/rfc/implemented/feature/2026-06-30-hook-bridges.md @@ -37,7 +37,7 @@ Each bridge maps the neutral `MergedHookOutcome` from the shared lib onto the se ### Adding context is not a veto — delegate, then fold -A hook that only attaches `additionalContext` (no block/deny) is NOT a decision the bridge should return on its own: returning `allow`/`accept` from a waterfall listener WITHOUT calling `next()` short-circuits every later `agent/prompt-submit` / `tools/post-execute` listener, so a policy/sandbox plugin registered after the bridge would never see the prompt.

Record a scenario that edits a seeded file without a preceding read: the edit is vetoed, the file stays unchanged on disk, and the transcript shows the pending edit card followed by a status:'failed' update carrying the policy error. --- examples/acp-agent/tests/acp.snapshot.ts | 1 + .../snapshots/fs-policy-reject/input.json | 7 + .../snapshots/fs-policy-reject/session.jsonl | 185 ++++++++++++++++++ .../fs-policy-reject/stdout.golden.jsonl | 136 +++++++++++++ .../fs-policy-reject/workspace/settings.txt | 1 + 5 files changed, 330 insertions(+) create mode 100644 examples/acp-agent/tests/snapshots/fs-policy-reject/input.json create mode 100644 examples/acp-agent/tests/snapshots/fs-policy-reject/session.jsonl create mode 100644 examples/acp-agent/tests/snapshots/fs-policy-reject/stdout.golden.jsonl create mode 100644 examples/acp-agent/tests/snapshots/fs-policy-reject/workspace/settings.txt diff --git a/examples/acp-agent/tests/acp.snapshot.ts b/examples/acp-agent/tests/acp.snapshot.ts index 7d19f44bb5..3a27ad25d0 100644 --- a/examples/acp-agent/tests/acp.snapshot.ts +++ b/examples/acp-agent/tests/acp.snapshot.ts @@ -59,6 +59,7 @@ const SCENARIOS: Scenario[] = [ { name: 'fs-edit', hasModelTurn: true, recorded: true }, { name: 'fs-write-overwrite', hasModelTurn: true, recorded: true }, { name: 'fs-read-window', hasModelTurn: true, recorded: true }, + { name: 'fs-policy-reject', hasModelTurn: true, recorded: true }, { name: 'multi-turn', hasModelTurn: true, recorded: true }, { name: 'error-finish', hasModelTurn: true, recorded: false }, { name: 'cancel', hasModelTurn: true, recorded: false }, diff --git a/examples/acp-agent/tests/snapshots/fs-policy-reject/input.json b/examples/acp-agent/tests/snapshots/fs-policy-reject/input.json new file mode 100644 index 0000000000..c44d44c675 --- /dev/null +++ b/examples/acp-agent/tests/snapshots/fs-policy-reject/input.json @@ -0,0 +1,7 @@ +{ + "steps": [ + { "op": "initialize" }, + { "op": "newSession" }, + { "op": "prompt", "text": "Do NOT use the read tool.

<53024+tianyicui@users.noreply.github.com> Date: Thu, 2 Jul 2026 23:42:16 +0800 Subject: [PATCH 055/168] refactor(events): remove the agent/stream-chunk mirror of assistant/chunk MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The loop recorded every model token delta as a durable `assistant/chunk` session event AND emitted an identical live `agent/stream-chunk` Cordis event one line later. Same StreamChunk, same turn/step; the emit added only the live Agent handle, which the sole consumer discarded. This is the boundary-mirror duplication the event-domain work removed for turn/step boundaries, applied to the token stream — a follow-up the boundary RFC explicitly deferred. The premise is settled: chunk persistence is authoritative (the proposal to stop persisting chunks was rejected — replay/snapshots depend on it), so `assistant/chunk` on `session/event` is the load-bearing token stream and `agent/stream-chunk` is pure redundancy. - Remove the `agent/stream-chunk` declaration + emit; drop the now-unused StreamChunk import from dsh-agent's types. - Migrate `dsh-ui-stdio` (the only live consumer; ACP already reads assistant/chunk off session/event) to render assistant/chunk in its existing session/event listener. Consolidating to one listener also makes the inReasoning dim-SGR flag deterministic across chunk/boundary events (they no longer race across two listeners). - Repoint the agent-loop tests (cancel/loop) and ui-stdio tests to the session/event assistant/chunk feed. - New RFC (implemented/simplification/2026-07-02-remove-stream-chunk-mirror); amend the boundary RFC's retained-list entry to cross-link; update architecture, cookbook, event-domain-semantics, the ACP proposal, and the regenerated cordis catalog.

(Fallback only if the factory is judged not worth it: inject `agentLoop` directly and record the architecture-rule exception in `docs/architecture.md`.) 2.

Internal edit — turn-end reason fidelity (sanctioned: edit internals to fit ACP). Extend `TurnEndReasonMap` in the proper places: (a) declaration-merge a `max-tokens` variant in the owning package (`packages/core/session/src/types.ts`, alongside `completed|aborted|error|disposed`) — add `max-tokens` because `FinishReasonMap` produces it (DeepSeek maps `length` → `max-tokens`); do not add `refusal`, since no current adapter produces it (unknown DeepSeek finish reasons collapse to `error`), but leave a comment in `TurnEndReasonMap` noting `refusal` should be added when an adapter first emits it (`FinishReasonMap` is merge-extensible); (b) make `agent-loop`'s `loop.ts` populate the reason from the model `finish` chunk — `assembler.finish` lives inside `runStep`, so `runStep` must return it up to `runTurn`, and the rule is "the last step's finish reason wins, but any `max-tokens` in the turn surfaces as `max-tokens`"; (c) no consumer exhaustively switches over `TurnEndReason` today (the invariants plugin switches on `SessionEventType`, and `deriveMessages` ignores `turn/end`), so adding `max-tokens` is a non-breaking extension — but recheck before landing; (d) update [docs/architecture.md](../../../architecture.md) (the CI-verified loop-lifecycle/event-taxonomy doc) and the affected package READMEs/JSDoc (`dsh-session`, `dsh-agent`, `dsh-agent-loop`) per the repo doc-sync policy.

Implement `session/load` on the session-persistence resume seam. 5. Permission gate: a single `tools/execute` listener registered with `prepend: true`, owning a `WeakMap` of bridge-created agents; no-op (`next()`) for unowned/no-agent calls; for owned calls → `session/request_permission` → allow (`next()`) / veto; settle the stored resolver exactly once on outcome, cancel, or connection close. 6. Example wiring (extract a shared base). `@cordisjs/plugin-include` is itself a plugin entry that resets `ctx.baseUrl` and loads a path, so a child `cordis.yml` can nest-include a shared base; the extraction is safe because every dependent plugin declares `inject` (loader groups initialize via `Promise.all`, so YAML order is NOT the dependency mechanism — never rely on it). Extract the provider/tool core (`llm, sessions, system-prompt, tools, agents, invariants, llm-deepseek, bash-local, tool-bash`) into `examples/base.yml`; have both `coding-agent` and a new `examples/acp-agent/` include it and add their own UI plugin plus logger. Keep `agent-loop` per-example (NOT in the base): `AgentLoop` creates its configured agents in its constructor, and the two examples disagree — `coding-agent` needs a pre-created `main` (its `stdio-chat` calls `ctx.agents.get('main')`), while `acp-agent` must pre-create none (ACP `session/new` creates agents). So `coding-agent` declares `agent-loop` with `agents: [{ id: main, … }]` and `acp-agent` with `agents: []`. `acp-agent` loads `dsh-session-persistence-jsonl` (from [session persistence](../../implemented/architecture/2026-06-14-session-persistence.md) — required for `session/load`), omits the stdout logger (see Risks), and adds `pnpm run demo:acp` plus the Zed `agent_servers` snippet. 7. Tests (the repo cares a lot here): a property-based test for the protocol shape (precedent: [property-based testing](../../implemented/testing/2026-06-11-property-based-testing.md)) — fuzz arbitrary harness event sequences and assert ACP-stream invariants (never a `tool_call_update` before its `tool_call`; exactly one `session/prompt` resolution per prompt; monotonic, well-formed ordering; `stopReason` in the legal set); codec unit tests over an in-memory `Duplex` pair (drive `AgentSideConnection` without a subprocess; assert exact frames for `initialize`, `session/new`, a full prompt turn); the mandatory HMR-safety test (dispose the fiber; assert the connection closed, all `ctx.on` listeners gone, any in-flight `request_permission` settled); failure-path tests (connection closes mid-stream; closes with a permission pending; a notification `send()` rejects but the turn survives; `finish{kind:'error'|'aborted'}`; a `tools/execute` throw with no `tool/result`; a second `session/new` rejected; a `session/prompt` while one is in flight; an empty prompt rejected without hanging; a `session/load` re-derives identical history and replays it); and an e2e (`*.e2e.ts`, self-skips without `DEEPSEEK_API_KEY`) that boots `examples/acp-agent`, connects a `ClientSideConnection`, sends a real prompt, owns and disposes the harness in `afterEach`, and verifies the world (files on disk), not the agent's self-report. diff --git a/packages/core/agent-loop/src/loop.ts b/packages/core/agent-loop/src/loop.ts index d08b5ccdba..eb55a8524d 100644 --- a/packages/core/agent-loop/src/loop.ts +++ b/packages/core/agent-loop/src/loop.ts @@ -158,7 +158,7 @@ export interface LoopHandle { * req = {model, system, tools, messages: session.deriveMessages(), signal} * req = waterfall agent/request ⟵ hooks/model-switch * stream ctx.llm.stream(req) ⟵ waterfall llm/stream (raw chunks) - * session('assistant/chunk'); emit agent/stream-chunk + * session('assistant/chunk') * msg = waterfall agent/step-result ⟵ BEFORE the log append, so the * session('assistant/message' {content, usage?}) session records what actually ran * each tool-call in msg (sequential, abort-checked): @@ -681,7 +681,6 @@ async function runStep( if (signal.aborted) throw new Error(String(signal.reason ??

Reply in the GitHub review thread (`gh api …/pulls/{pr}/comments/{id}/replies`), not as a top-level comment, stating the fix and the commit that carries it. +## Landing changes cleanly: gates, Codex, and scope + +Hard-won from the hooks stack (#118–#129). The recurring theme: a mechanical gate proves lines ran and types check; it does NOT prove semantics, doc accuracy, or that a test guards anything. Layer the cheap human/AI judgment on top, in the right order, and keep each unit of work honestly scoped. + +- **Every regression test must be proven RED on the unfixed code, and this is the top-billed discipline, not a footnote.** Neuter the fix (comment out the one line, or revert the source), run the new test, watch it fail, then restore. A guard that passes both ways guards nothing — and a green 100%-coverage suite actively hides this (the line ran; it just asserted nothing load-bearing). This caught real bugs repeatedly here: a `structuredClone` aliasing fix, a bridge `expectedEventName` discriminator guard, a blocking-Stop-hook reason fallback. Do it for EVERY guard, every time; the proof takes thirty seconds and is the only thing that certifies the test. +- **Run `pnpm run test:coverage` (the FULL suite), not an isolated `-t` filter, before trusting green.** Test-isolation bugs surface only in the full run: here twelve fixed-`setTimeout` waits raced under full-suite load and passed in isolation but flaked together — fixed by replacing every fixed sleep with a `waitFor(predicate)` poll (ties to [§ Defensive patterns](#defensive-patterns-hard-won) "Async state is not synchronous state"). A suite that is green under `-t ` but red under `test:coverage` is telling you about shared state, not a flake to rerun. +- **Codex convergence is for the class of defect gates STRUCTURALLY cannot catch — spend it there.** `xhigh` Codex reliably finds what `typecheck`/`lint`/`coverage`/`doc-sync` are blind to: (a) **prose/RFC/comment drift** the doc-sync scope doesn't scan — e.g. two package READMEs still advertising a removed event, or an RFC claiming a `block` decision "carries context too" when that union has no such field; (b) **a bug you INTRODUCED while fixing** — the fix's own new branch, un-covered by the test you wrote for the original bug; (c) **dishonest test comments** blessing a wrong assertion. Treat a Codex finding as a claim to verify against the code, then re-bucket it yourself (its own (A)/(B)/(C) label is an input, not a verdict) — but know that "clean gates" is exactly when Codex earns its keep. +- **Scope a Codex review to ONE fix or concern.** A convergence prompt bundling two independent fixes plus verification context timed out at the 850s cap with no verdict — a wasted ~14-minute run — then completed fine once split into two smaller serial reviews. One concern per review is faster AND yields a sharper verdict. (For the invocation: the prompt is a POSITIONAL arg to `ask-codex.sh`, not `--file`; the only flags are `--codex-model`, `--codex-timeout`. Multi-paragraph prompts go via `"$(cat file)"`.) +- **A cleanup or removal discovered mid-review that exceeds the reviewed RFC's scope goes in a NEW stacked PR, even though pre-release churn is cheap.** Do not retroactively widen a diff a reviewer already signed off on, and do not fold a fresh decision into a converged PR. Before deleting an event/seam, first enumerate every consumer and prove redundancy (here: `agent/stream-chunk` was proven a pure mirror of the durable `assistant/chunk` — ACP already read the durable one, the stdio UI ignored the live-only args), then grill the removal ("am I deleting a seam someone will re-add?"). The removal became its own PR-G with its own RFC, not an amendment to the reviewed #118. +- **Regenerate a generated artifact as PART of the edit that invalidates it, not as a gate to fail.** Any edit to a `types.ts` `interface Events`/`Context` block or a module doc the generator reads makes `docs/cordis-catalog/events-and-services.md` stale; run `pnpm run gen-cordis-catalog` (and `gen-module-graph`) in the same step rather than letting `doc-sync` discover it. Likewise run `pnpm run lint:fix` before hand-fixing a new test file — the auto-fixable churn (quotes, `max-len`) should never consume review attention meant for the real errors. +- **Read a failure before reacting: environmental ≠ code.** `ENOSPC: file watchers` from many concurrent worktrees fails the `tsx`-based `demo:echo` smoke, but the label/output already rendered correctly before the watcher died and the published-artifact built-bin smoke (plain `node`, no watcher) is unaffected. Recognize the class on the FIRST occurrence — fall back to the watcher-free check or prune stale worktrees — rather than burning retry cycles on a transient the code never caused. + + ## Architecture This codebase is based on the **Cordis** framework, built microkernel-style: **everything is a plugin**. All necessary Cordis dependencies are copied into this monorepo as vendored source (under `vendor/`) instead of being depended on via npm. @@ -275,6 +288,8 @@ Each bullet is a bug class that bit us; the rule prevents the reoccurrence. - **A real-load-path test only GUARDS the export shape if a broken shape actually FAILS it.** The original crash (`cannot get property … without inject`) fired because that plugin HAS `inject`. A plugin with NO `inject` (a composition/bundle plugin that mounts children carrying their own inject, e.g. `dsh-agent-core` and the app packages) does NOT crash on a stray `export default` — `unwrapExports` silently drops `Config`/`name` and the plugin boots anyway — so a Loader smoke stays green while the export shape is broken. For such plugins add an EXPLICIT assertion that the regression fails: `expect('default' in mod).toBe(false)` plus running the module through the real `Loader.prototype.unwrapExports` and asserting `name`/`Config`/`apply` survive. Prove it: add `export default apply`, watch the test go red, revert. - **"Real entry path" means the PUBLISHED ARTIFACT, not the dev runtime.** A test (or a `demo:*` smoke) that boots `src/bin.ts` under `tsx` is NOT the same code a consumer runs — the package `bin` field points at the built `lib/bin.js` under plain `node`. tsx masks failure modes the published artifact has: a boot settle-race that exits 0 before the app's handles attach, module-resolution differences (the unbuilt `paths` map vs node_modules), and a load failure that `loader.await()`'s `Promise.allSettled` SWALLOWS so a typo'd config silently exits 0. The guard is a smoke that runs the built `lib/bin.js` under plain `node` in a node_modules-shaped temp dir (symlinked workspace + vendor packages), asserts the real output, AND asserts a genuinely-missing config exits NON-ZERO. The tsx demo is necessary but not sufficient; the published-bin smoke is what catches "green under tsx, broken on install". - **Tag spelling and EOF hygiene.** cordis.yml interpolates env via the `!!js` tag (js-yaml resolves custom tags under `tag:yaml.org,2002:js`), not `!js` — keep code, comments, and docs consistent. Files end with exactly one trailing newline; `git diff --check` (a pre-push gate) rejects new blank lines at EOF. +- **`child_process.spawn` narrows non-null `stdout`/`stderr` only from a LITERAL `stdio` tuple.** A ternary or variable in a `stdio` slot (e.g. `stdio: [wantStdin ? 'pipe' : 'ignore', 'pipe', 'pipe']`) selects the generic `spawn` overload, widening the child's streams to nullable — which then trips `no-non-null-assertion` (forbidden in `src`). Write two full `spawn(...)` calls with literal tuples in an `if`/`else` (or a ternary between two complete calls), as [`dsh-bash-local`'s `run.ts`](packages/bash/bash-local/src/run.ts) does, so each branch's literal tuple keeps the typed overload. This trap bit twice — recognize it the moment a conditional `stdio` slot appears. +- **`AgentLoop.create(id, options)` DROPS `options.meta` — only the async factory path threads it.** The synchronous `create()` prepares its session with a hardcoded `{ meta: {} }`; a test (or caller) that needs `session.header.cwd` or other header metadata to take effect must use the factory `ctx.agents.create({ agentId, sessionId, meta, agentOptions })` (or `resume`), which passes `meta: options.meta ?? {}`. A cwd-dependent test that silently sees an empty cwd is almost always this. See `packages/core/agent-loop/src/index.ts`. ## Type Safety and Documentation From 665c10ff1980482929358199a21fc504108066f7 Mon Sep 17 00:00:00 2001 From: Tianyi Cui <53024+tianyicui@users.noreply.github.com> Date: Fri, 3 Jul 2026 01:13:52 +0800 Subject: [PATCH 059/168] docs(graphs): add generated documentation atlas --- README.md | 2 +- docs/architecture.md | 4 +- docs/development.md | 4 +- docs/graphs/README.md | 26 + docs/graphs/agent-lifecycle.md | 41 + docs/graphs/app-composition.md | 90 ++ docs/graphs/capability-seams.md | 110 +++ docs/graphs/event-producer-consumer.md | 36 + docs/graphs/hot-reload-disposal.md | 24 + docs/graphs/package-topology.md | 189 ++++ docs/graphs/session-surface.md | 25 + docs/graphs/snapshot-replay.md | 24 + docs/graphs/subagent-lineage.md | 27 + docs/graphs/tool-affordance-map.md | 35 + docs/graphs/tool-execution-pipeline.md | 30 + docs/rfc/README.md | 1 + .../2026-07-03-documentation-graph-atlas.md | 66 ++ package.json | 4 +- scripts/gen-doc-graphs.ts | 851 ++++++++++++++++++ 19 files changed, 1584 insertions(+), 5 deletions(-) create mode 100644 docs/graphs/README.md create mode 100644 docs/graphs/agent-lifecycle.md create mode 100644 docs/graphs/app-composition.md create mode 100644 docs/graphs/capability-seams.md create mode 100644 docs/graphs/event-producer-consumer.md create mode 100644 docs/graphs/hot-reload-disposal.md create mode 100644 docs/graphs/package-topology.md create mode 100644 docs/graphs/session-surface.md create mode 100644 docs/graphs/snapshot-replay.md create mode 100644 docs/graphs/subagent-lineage.md create mode 100644 docs/graphs/tool-affordance-map.md create mode 100644 docs/graphs/tool-execution-pipeline.md create mode 100644 docs/rfc/implemented/process/2026-07-03-documentation-graph-atlas.md create mode 100644 scripts/gen-doc-graphs.ts diff --git a/README.md b/README.md index 1ce5aa8960..2d97f103af 100644 --- a/README.md +++ b/README.md @@ -17,6 +17,6 @@ pnpm run demo:echo # runnable echo-agent example (no API key needed) pnpm run demo:coding # the real DeepSeek coding agent (needs DEEPSEEK_API_KEY) ``` -For humans, start with the [development guide](docs/development.md) for local setup, hooks, environment variables, and quality gates, then read the [architecture design](docs/architecture.md) before package work.

A maintainer still has to synthesize the relationships: which packages form a capability seam, which app bundles a concrete spine, which event is durable vs live, where a hook or policy plugin can intercept work, and which model-facing tool depends on which service. An SDK user has the same problem from another angle: "Which package do I install or load for the behavior I want, and which event/service/tool do I extend?" + +The pressure is already visible in the open stacks even though this implementation is based on `origin/master`: the hooks stack through PR #129 makes event producer/consumer topology and interception points much more important, while the filesystem stack through PR #128 makes capability seams, policy vetoes, tool presentation, and SDK assembly paths much more important.

Files end with exactly one trailing newline; `git diff --check` (a pre-push gate) rejects new blank lines at EOF. - **`child_process.spawn` narrows non-null `stdout`/`stderr` only from a LITERAL `stdio` tuple.** A ternary or variable in a `stdio` slot (e.g. `stdio: [wantStdin ? 'pipe' : 'ignore', 'pipe', 'pipe']`) selects the generic `spawn` overload, widening the child's streams to nullable — which then trips `no-non-null-assertion` (forbidden in `src`). Write two full `spawn(...)` calls with literal tuples in an `if`/`else` (or a ternary between two complete calls), as [`dsh-bash-local`'s `run.ts`](packages/bash/bash-local/src/run.ts) does, so each branch's literal tuple keeps the typed overload. This trap bit twice — recognize it the moment a conditional `stdio` slot appears. -- **`AgentLoop.create(id, options)` DROPS `options.meta` — only the async factory path threads it.** The synchronous `create()` prepares its session with a hardcoded `{ meta: {} }`; a test (or caller) that needs `session.header.cwd` or other header metadata to take effect must use the factory `ctx.agents.create({ agentId, sessionId, meta, agentOptions })` (or `resume`), which passes `meta: options.meta ?? {}`. A cwd-dependent test that silently sees an empty cwd is almost always this. See `packages/core/agent-loop/src/index.ts`. +- **`AgentLoop.create(id, options)` DROPS `options.meta` — only the programmatic factory `create` threads it.** The convenience `create()` prepares its session with a hardcoded `{ meta: {} }`; a test (or caller) that needs `session.header.cwd` or other header metadata to take effect must use the factory `ctx.agents.create({ agentId, sessionId, meta, agentOptions })` (which passes `meta: options.meta ?? {}`), or `resume` (which reloads the persisted header). Both are synchronous. A cwd-dependent test that silently sees an empty cwd is almost always the wrong creation path. See `packages/core/agent-loop/src/index.ts`. ## Type Safety and Documentation From 8caf9231967a4761d6c1cd31ee5516f319864969 Mon Sep 17 00:00:00 2001 From: Tianyi Cui <53024+tianyicui@users.noreply.github.com> Date: Fri, 3 Jul 2026 01:32:01 +0800 Subject: [PATCH 061/168] docs(graphs): verify mermaid syntax --- .github/workflows/ci.yml | 6 +- docs/development.md | 1 + docs/graphs/agent-lifecycle.md | 36 +- docs/graphs/tool-execution-pipeline.md | 20 +- .../2026-07-03-documentation-graph-atlas.md | 3 +- package.json | 6 +- pnpm-lock.yaml | 1157 ++++++++++++++++- scripts/gen-doc-graphs.ts | 56 +- scripts/verify-mermaid.ts | 107 ++ 9 files changed, 1328 insertions(+), 64 deletions(-) create mode 100644 scripts/verify-mermaid.ts diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 9064a38cea..4212717339 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -49,10 +49,10 @@ jobs: # Doc-sync gates (doc-sync-enforcement RFC). doc-typecheck compiles the # fenced ts blocks against the root project-reference graph.

A tool declares one render intent per call/result and the ACP bridge switches on `card`: ToolCallView = generic | terminal | diff ToolResultView = generic | terminal The `diff` card is new: fs write/edit now emit an ACP {type:'diff'} content block (an editor's inline diff), which the old shapes could not express. The bridge also relativizes a file card's title against the session cwd (mirroring claude-agent-acp's toDisplayPath) while keeping locations/diff paths raw, and derives the no-capability fenced console fallback from a terminal result's output. read gains the window-in-title (`Read foo.txt (5 - 8)`) and an always-set location line, matching the reference adapter field-for-field. Migrates all three producer families (tool-fs, tool-bash, tool-todo) and the sole consumer (the ACP bridge) together — the source does not compile piecewise.

Review findings get regression tests (see `packages/core/agent-loop/tests/review-fixes.spec.ts`).

A green mock/no-key suite proves the plumbing, not the product — the with-key smoke test is what catches "green units, broken product".

Mock only the genuinely expensive/non-deterministic boundary (the LLM adapter, the network, the clock) and keep everything downstream real: a bridge tool-call test runs the scripted mock MODEL but the REAL tool + REAL executor (e.g. `makeBridgeHarness({ withBash: true })` plugs `dsh-bash-local` + `dsh-tool-bash` and runs an actual `echo`), so it verifies the actual `presentCall`/`presentResult` an editor sees.

This keeps the bash tool's result a single structured shape and preserves the existing capability-gated behavior byte-for-byte. + +### Purity preserved + +`presentCall`/`presentResult` remain pure functions of `args` (+ the result for `presentResult`) — they run on live streaming AND session-log replay, so they must be replay-deterministic. Every view is derived from args alone: write's diff is new-file style (`oldText:null`) because the tool has no old content at call time; edit's diff is `old_string`→`new_string`. + +## Relative-path display titles + +`claude-agent-acp` relativizes a file card's title path against the session cwd (`toDisplayPath`) — `Read src/foo.ts`, not `/abs/proj/src/foo.ts` — while keeping `locations[]`/`diff.path` **raw** (the editor opens the real path). Our `presentCall` is pure/args-only and cannot see the session cwd, so this relativization happens at the **bridge**, which already threads the session cwd into tool-call rendering (the same cwd it uses to resolve a terminal card's header). The bridge relativizes the title only, by an exact structured replace of the known `locations[0].path`/`diffs[0].path` substring — generic over the file-card kinds, never special-casing tool names. + +## Non-goals + +- **Applied-hunk diffs.** `claude-agent-acp` additionally rewrites Write/Edit diffs at *result* time with real structured-patch hunks (via a PostToolUse hook: `toolUpdateFromDiffToolResponse`). Our diffs are call-time and args-derived (the whole `old_string`→`new_string`, no surrounding context lines), because `presentResult` sees only `{content, isError}` and `FsEditOutcome` carries a replacement count/version, not hunk text. Real hunks would need a new result/event shape carrying the patch — a follow-up, not this change. This is the one remaining representation difference from `claude-agent-acp`, and it is architectural (needs a new event), not cosmetic. +- **Live incremental `terminal_output_delta` streaming** and **command classification** — the terminal-rendering RFC's own deferred follow-ups, untouched here. + +## Related + +- Supersedes the deferral in [Collapse tool-owned UI presentation](../../rejected/simplification/2026-06-20-generic-tool-rendering.md) (rejected — "wait for two real tools and two real consumers, then a tagged render-intent union").

`dsh-tools` `presentCall`/`presentResult` seam — a UI never special-cases tool names. For `bash`: the **title** is the exact `command` ("ls -la src") and `kind` is `execute` (terminal/run treatment), matching the reference ACP adapters (claude-agent-acp, codex-acp), which both use the bare command as an execute tool's title. The command is ALSO the **rawInput** for non-terminal UIs that render it (an execute-kind card hides rawInput — Zed shows it only for non-terminal tools — so the command must BE the title to be seen). The model-written `description` rides as a **content** text block shown ABOVE the card. (claude-agent-acp DROPS the description in terminal mode and shows only the card; surfacing it as a content block is a deliberate divergence — we keep the human summary visible alongside the card.) The completed output is wrapped in a fenced ` ```console ` block as the no-terminal-capability fallback — a UI-only affordance, so the model-facing result text stays unfenced. A FOREGROUND `bash` run also flags itself as a **terminal** (the neutral `terminal` field: `presentCall` sets a `cwd` from the model `workdir` when given — absolute as-is, relative for the UI bridge to resolve against the session cwd — else leaves it for the bridge to fill from the session cwd; `presentResult` carries the raw output plus the parsed `exitCode`/`signal`) so a capable client (Zed) renders a terminal card with an exit-status pill instead of the text block — see `packages/ui/acp` ("Terminal card"). A `run_in_background` call is NOT a terminal (it returns a task id immediately and never streams a terminal — poll with `bash_output`), and an `isError` result (spawn failure / abort) carries no exit pill (there is no real process exit); both render as the ordinary execute card / fenced text. `bash_output`/`bash_kill` present a task-scoped title ("Read output from background task bash-3" / "Kill background task bash-3") with the task id as rawInput. These methods are pure/display-only (they also run on `session/load` replay), and a malformed/older logged arg shape falls back to a generic presentation rather than throwing.

A FOREGROUND `bash` run declares a **terminal card**: `presentCall` returns `{ card: 'terminal', title, description?, cwd? }` — the **title** is the exact `command` ("ls -la src"), the model-written `description` rides along (rendered ABOVE the card), and `cwd` comes from the model `workdir` when given (absolute as-is, relative for the UI bridge to resolve against the session cwd; else left for the bridge to fill from the session cwd) — and `presentResult` returns `{ card: 'terminal', title?, output?, exitCode?, signal? }` carrying the raw output plus the parsed `exitCode`/`signal`, so a capable client (Zed) renders a terminal card with an exit-status pill. The result carries the raw `output`; the bridge DERIVES the ` ```console ` fenced fallback for a no-terminal-capability UI (the tool no longer encodes the fences itself), so the model-facing result text stays unfenced. A `run_in_background` call is NOT a terminal (it returns a task id immediately and never streams a terminal — poll with `bash_output`) and instead returns a **generic card** (`{ card: 'generic', title, kind: 'execute', rawInput: command, content: [description] }`); an `isError` result (spawn failure / abort) likewise returns a `generic` result view with no exit pill (there is no real process exit). `bash_output`/`bash_kill` return a `generic` card with a task-scoped title ("Read output from background task bash-3" / "Kill background task bash-3") and the task id as rawInput.

The views are provider-neutral — the ACP bridge (`dsh-acp`) maps each `card` to ACP `tool_call`/`tool_call_update` wire fields (a `diff` card to a `{ type: 'diff' }` content block, a `terminal` card to the `_meta` terminal convention), and relativizes a file card's title against the session cwd. See the render-intent-union RFC (`docs/rfc/implemented/architecture/2026-07-02-tool-render-intent-union.md`); `dsh-tool-bash` (terminal) and `dsh-tool-fs` (diff/generic) are the reference implementations. ```ts import { defineTool } from '@deepseek-ai/dsh-tools' @@ -90,13 +95,13 @@ const bash = defineTool({ async execute(args) { return [{ type: 'text', text: `ran: ${args.command}` }] }, - // The command is the readable title; the description rides as a content block. - presentCall: args => ({ title: args.command, kind: 'execute', rawInput: args.command, content: [{ type: 'text', text: args.description }] }), - // Wrap the output as a console block for the UI (not in the model-facing result). + // A terminal card: the command is the title, the description renders above it. + presentCall: args => ({ card: 'terminal', title: args.command, description: args.description }), + // A terminal result: the raw output + exit; the bridge derives the fenced fallback. presentResult: (_args, result) => { const block = result.content.length === 1 ? result.content[0] : undefined if (block === undefined || block.type !== 'text') return undefined - return { content: [{ type: 'text', text: '```console\n' + block.text + '\n```' }] } + return { card: 'terminal', output: block.text } }, }) ``` diff --git a/packages/core/tools/src/index.ts b/packages/core/tools/src/index.ts index c2f324e87b..594e5761cb 100644 --- a/packages/core/tools/src/index.ts +++ b/packages/core/tools/src/index.ts @@ -62,150 +62,182 @@ declare module 'cordis' { */ export type ToolCallKind = 'read' | 'edit' | 'delete' | 'move' | 'search' | 'execute' | 'fetch' | 'other' -// FIXME(tool-presentation): the ToolCallPresentation / ToolResultPresentation / -// ToolTerminal shapes need a rethink.

The bridge looks the definition up by name in `ctx.tools` and `switch (view.card)`es to build the ACP `tool_call`/`tool_call_update` wire shape per card; a tool that declares neither gets a generic fallback (title = tool name, raw parsed args as `rawInput`, kind inferred from the name). For example `dsh-tool-bash` returns a `terminal` card for a foreground `bash` (title = the exact `command` "ls -la src", `description` = the model description); the `dsh-tool-fs` `write`/`edit` tools return a `diff` card and `read` returns a `generic` card (`kind: 'read'`, the read window in its title — `Read foo.txt (5 - 8)` — and a `locations` entry for the file). For a file card the bridge **relativizes the title** against the session cwd (mirroring `claude-agent-acp`'s `toDisplayPath` — `Read src/foo.ts`, not the absolute path) while keeping `locations[]`/`diffs[].path` **raw** so the editor opens the real path. The `tool/result` session event carries only `{ callId, content, isError }` — not the tool name or args — so to call a tool's `presentResult` the bridge keeps a small per-session map from `callId` to the in-flight call's `(name, args)`, populated on `tool/call` and removed as each result is presented (it holds only currently-in-flight calls, never finished ones). This is bridge-local state — NOT a change to the event schema or a core service. The map lives on the `SessionRecord`, so two concurrent sessions never cross their in-flight tool state; a `session/load` replay uses a throwaway presenter that pairs each `tool/call` with its `tool/result` as the log replays in order, so replayed tool cards render identically to live ones. ## Terminal card (capability-gated) -A tool whose call IS a shell command (`bash`) can render as a real **terminal card** — a working-directory header with the command's output and an exit-status pill — rather than a plain text block.

Adding a result card later now fails to compile at the switch.

Test for a `..` SEGMENT (`..` alone or `..…`) so such paths relativize, matching claude-agent-acp's `cwd + sep` prefix check.

Maintaining a second language by hand, with no mechanism, is how translations rot: the English file moves on, the Chinese file silently lies, and no gate notices. The repo's standing answer to invariants of this kind is to encode them as a mechanical check (see [quality gates](2026-06-11-quality-gates.md) and [doc-sync enforcement](2026-06-11-doc-sync-enforcement.md)), so the bilingual policy ships with one. + +## Decision + +- **Paired sibling files, English canonical.** The translation of `foo.md` is `foo.zh.md` in the same directory; English is the only authoring language and translation flows EN → ZH.

Freshness automation exists outside China: MDN's `l10n.sourceCommit` front-matter fingerprint, Vue's Ryu-Cho action (upstream-commit watcher that opens issues/PRs for stale translations), Kubernetes' localization drift scripts, and Microsoft's Azure co-op-translator (source-hash-driven LLM re-translation in CI).

Recursive traversal, globbing, pagination, search, file watching, and model-facing rendering are intentionally out of scope. + +The local backend implements this through `readdir({ withFileTypes: true })`, `resolveLocalTarget`, and metadata `stat`/`realpath` probes. The result order is deterministic (`name.localeCompare`) to keep prompt/listing output stable for future consumers and improve prefix-cache reuse. + +Broken or disappeared children may be represented as `type: 'other'` without `version`/`size`; they do not abort the whole listing. Permission or backend I/O failures while listing the directory or resolving/probing child metadata fail the whole listing with structured `FsError` codes: + +- `FS_NOT_FOUND` for missing targets. +- `FS_NOT_DIRECTORY` for existing non-directory targets. +- `FS_PERMISSION_DENIED` for permission failures. +- `FS_IO_ERROR` for other backend I/O failures. +- `FS_ABORTED` for aborted calls. + +## Rejected alternatives + +**Add a model-facing list tool now.** Rejected for this PR. The immediate request is the provider seam, and the user explicitly asked not to change skill loading or other upper layers in this branch. A model-facing tool needs prompt/schema/rendering decisions that should be reviewed separately. + +**Keep directory enumeration in each consumer.** Rejected. That would bind product packages such as `dsh-skill` to Node/local filesystem behavior and bypass policy/remote/sandboxed backends. + +**Make `listDir` recursive or glob-shaped.** Rejected for now. Skill-root discovery only needs direct children, and a simple direct listing is the smallest backend contract future consumers can safely compose. + +**Skip children that fail metadata resolution.** Rejected. The API promises resolved child targets, so permission/IO failures while resolving a child are contract failures. Broken or disappeared children are the exception because they can still be represented without claiming a live resolved file. + +## Consequences + +Every filesystem backend must now implement one additional provider primitive. That is deliberate foundation work while the harness is still unreleased, but it does mean future sandboxed/remote backends need to define equivalent direct-child listing behavior. + +The capability remains provider-facing. Until a consumer lands, ACP/model sessions will still need existing tools such as `bash` for directory listing.

Exa gains searchType, numResults, and highlightsPerResult; Perplexity gains maxTokens (it previously sent none) and an optional searchRecency. Each follows the deepseek provider's shape: a defaulted Config field, a DEFAULT_* constant, and a positive-integer status() check for numeric limits. The call-level maxResults still flows through WebSearchRequest and wins over the configured default, keeping the seam layering intact.

Every existing `.zh.md` file — required or not — passes all of: its English source exists (no orphans), its fingerprint matches the source's current blob hash (no stale translations), both sides carry the language switcher, and its fenced-code-block and heading counts equal the source's. +2. Every existing `.zh.md` file — required or not — passes all of: its English source exists (no orphans), its fingerprint matches the source's current blob hash (no stale translations), both sides carry the language switcher, and its structural signature matches the source in order — heading depths, verbatim code blocks (info string and content), table column counts, list kinds, and every link target apart from the switcher. 3. Files listed as `excluded` have no `.zh.md` sibling at all. `pnpm run verify-translation-pairing --list` prints the current translation state of every document in scope — missing, stale, or ok — and is the work list for translation batches. It never fails; it reports. The practical rule this gate creates: **when a PR edits an English document that has a `.zh.md` sibling, the same PR updates the translation** (run the [dsh-translate-docs](../../.agents/skills/dsh-translate-docs/SKILL.md) skill), exactly like the repo's existing doc-sync rule for code and READMEs. A PR that leaves a translation stale goes red in CI. +The gate's limit, stated plainly: **a green gate means fresh and structurally sound, not verified.** It checks the fingerprint and the shape; it cannot judge whether the Chinese is accurate, well-termed, or natural — that is the reviewer's half of the contract, per [translation-rules.md](translation-rules.md). A re-fingerprinted `.zh.md` with a sloppy translation passes the gate; it must not pass review. + ## Scope, exclusions, and rollout **Scope**: the root `README.md` and everything under `docs/**`.

The call-time snippet diff stays; the result hunk supersedes it (ACP content-replace). Mechanism: - A persisted tool-private `meta` channel: execute may return `{ content, meta }`; `meta` (JsonValue) rides on the tool/result event and is handed back to presentResult, so the diff reproduces on replay (event-sourced). JsonValue is now exported from dsh-session. - The backend returns raw before/after text (storage facts) on FsWriteOutcome/FsEditOutcome; the tool computes the hunk via the npm `diff` package's structuredPatch. A create has no before → no result diff; a failed/aborted mutation carries no meta. - ToolResultView gains a DiffResultView; the bridge's result-side switch renders it as {type:'diff'} content blocks. RFC: docs/rfc/implemented/architecture/2026-07-02-result-time-applied-hunk-diffs.md (justifies the npm `diff` runtime dep over vendoring and the meta channel); the render-intent-union RFC's Non-goal is updated to record this shipped.

An editor renders that as an inline diff, but it is a **context-free** diff — the bare `old_string`→`new_string` with no surrounding lines, and a `replace_all` that touched five scattered sites still renders as one snippet pair. + +Driving `claude-agent-acp`'s own ACP bridge shows what a full editor diff looks like: after the mutation applies, it emits a SECOND `tool_call_update` whose diff is the **applied hunk with ±3 context lines** (and one hunk per changed site for `replace_all`), reconstructed from the tool's `structuredPatch`. That result-time hunk is what makes Zed show the change *in place* in the file rather than as a floating snippet. Our tools stopped at the call-time snippet; the completed result carried only the plain "updated successfully" text, no diff. + +The obstacle is a seam boundary: `presentResult(args, result)` is a **pure function of `args` + the model-facing `result` (`{content, isError}`)** — it runs on live streaming AND on session-log replay, so it must be replay-deterministic and cannot do I/O. It never sees the file's before/after content, and `FsEditOutcome`/`FsWriteOutcome` carried only a replacement count + version, not the text. So there was no way to compute — or even carry — an applied hunk to the presenter. + +## Decision + +Add a **persisted, tool-private presentation channel** so a tool's `execute` can attach a result-time render payload that survives replay, and use it to carry the applied-hunk diff. + +### 1.

The registry threads it onto the `tool/result` **session event** (`{ …, meta?: JsonValue }`), so it is persisted with the log; on replay the same `meta` is read back and handed to `presentResult` via a widened `ToolResult` (`{ content, isError, meta? }`). Because the payload lives in the event log, the diff reproduces on session reload / snapshot replay **for free** — the event-sourcing guarantee, not a re-computation. `JsonValue` is exported from `dsh-session` (paired with the existing `isJsonValue` predicate that already gates every event's serializability at `append`). + +This is the general shape ("a tool attaches durable result presentation"), not an fs-specific one — any tool can use it. + +### 2. The tool computes the hunk; the backend returns before/after (fs) + +Per the [capability-seam split](2026-06-13-capability-seams.md), the storage backend returns only **storage facts** and the model-facing tool owns **presentation**: + +- `dsh-fs` widens `FsEditOutcome` with `{ before: string; after: string }` and `FsWriteOutcome` with `{ before: string | null; after: string }` (`before: null` ⇒ a create, or an existing-but-undiffable binary/non-UTF-8 file). The local backend already holds both texts at write time; it returns them as raw LF-normalized text, with **no diff/UI concept** entering the seam. +- `dsh-tool-fs` computes the contextual hunk from before/after and attaches it as `meta: { diffs: FileDiff[] }`. A result diff is emitted only when a before-version exists — edit always; write on overwrite; **a create emits none** (there is no before), matching `claude-agent-acp`'s empty `structuredPatch` on create. A failed/aborted/policy-rejected mutation applied nothing, so it carries no `meta` and renders no result diff. + +### 3. The bridge renders a `diff` result card + +`ToolResultView` gains a `DiffResultView { card:'diff'; title?; diffs: FileDiff[] }`; the bridge's result-side `switch (view.card)` gets a `diff` arm emitting the `{type:'diff'}` `ToolCallContent` blocks (mirroring the call-side arm). An ACP `tool_call_update.content` REPLACES the call's content in an editor, so the result-time contextual hunk **supersedes** the call-time snippet — the two-update sequence (call snippet, then result hunk) matches `claude-agent-acp` exactly. + +### The diff algorithm — a third-party runtime dependency over vendoring + +Computing hunks-with-context is a solved problem with sharp edge cases (grouping, context coalescing, the trailing-newline marker). Rather than hand-roll it, `dsh-tool-fs` takes a runtime dependency on the npm [`diff`](https://www.npmjs.com/package/diff) package (v9, ships its own types) and uses its `structuredPatch`. The repo's default is to vendor Cordis-framework source, but that policy is about the *framework*; a leaf tool package taking a small, well-known, self-typed utility dependency is the same shape as `dsh-acp` depending on `@agentclientprotocol/sdk`. Vendoring a diff algorithm would be re-implementing a battle-tested one for no benefit — the [pre-release "foundation over blast radius"](../../../../AGENTS.md) reasoning does not argue for re-deriving standard algorithms.

CRLF write overwrite emitted bogus every-line-changed hunks: write's `before` was LF-normalized but `after` kept the raw model content, so a CRLF rewrite of an LF file diffed every line. Normalize write's `after` to LF so both sides share the diff basis (edit already did). Regression test proves it fails on the raw-after path. - The tool-private `meta` payload is now typed `unknown` (opaque) at every seam instead of `JsonValue`. This drops the `dsh-tools -> dsh-session` package edge that existed only to name the type, and removes the `FileDiff` index signature that had been widening the type solely for JsonValue-assignability. Serializability is still enforced at runtime by `Session.append`'s isJsonValue check, which was always the real guard. - Sync the docs the new result/meta surface left stale: ToolResultView's diff card + ToolExecutionResult.meta in tools.md/session.md type-equiv blocks, the acp/tools READMEs, and the adding-a-tool cookbook; regenerate the cordis catalog and module graph. --- docs/cookbook/adding-a-tool.md | 3 +- docs/cordis-catalog/events-and-services.md | 6 ++-- docs/core-data-structures/session.md | 2 +- docs/core-data-structures/tools.md | 4 +-- docs/module-graph.md | 3 +- ...26-07-02-result-time-applied-hunk-diffs.md | 8 ++--- packages/core/session/src/types.ts | 15 +++++---- packages/core/tools/README.md | 4 +-- packages/core/tools/package.json | 2 -- packages/core/tools/src/index.ts | 31 +++++++------------ packages/fs/fs-local/src/fsio.ts | 2 +- packages/fs/fs-local/src/index.ts | 6 +++- packages/fs/fs-local/tests/filesystem.spec.ts | 12 ++++--- packages/fs/fs/src/types.ts | 6 ++-- packages/fs/tool-fs/src/diff.ts | 18 +++++------ packages/ui/acp/README.md | 2 +- packages/ui/acp/src/index.ts | 4 +-- pnpm-lock.yaml | 3 -- 18 files changed, 63 insertions(+), 68 deletions(-) diff --git a/docs/cookbook/adding-a-tool.md b/docs/cookbook/adding-a-tool.md index c5e7931871..84247e3f3d 100644 --- a/docs/cookbook/adding-a-tool.md +++ b/docs/cookbook/adding-a-tool.md @@ -36,6 +36,7 @@ Registration is effect-based: disposing the plugin fiber unregisters the tool (w - **Args are validated for you.** `defineTool` validates the model-generated `arguments` against the `SchemaSpec` before `execute` runs (type, required keys, enum membership, nested objects/arrays — [runtime arg validation](../rfc/implemented/architecture/2026-06-11-runtime-arg-validation.md)), so inside `execute` the args already match `InferArgs`.

Returning `undefined` (or omitting a method) tells a UI to fall back to a generic presentation (title = tool name, raw args as input, raw result content). Both methods must be **pure and side-effect-free**: a UI may call them during live streaming AND during a session-log replay, so they depend only on their arguments. `result.meta` is the tool's own optional presentation payload (opaque `unknown`, JSON-serializable), attached by `execute` (see below) and persisted on the `tool/result` event, so a `presentResult` reading it stays replay-deterministic (the same `meta` is read back from the log). With `defineTool`, `args` is the typed `InferArgs` shape; the helper soft-validates before calling (a malformed/older logged arg shape yields `undefined` rather than throwing, since display must never crash a replay). The views are provider-neutral — the ACP bridge (`dsh-acp`) maps each `card` to ACP `tool_call`/`tool_call_update` wire fields (a `diff` card to a `{ type: 'diff' }` content block, a `terminal` card to the `_meta` terminal convention), and relativizes a file card's title against the session cwd.

The `tool/result` session event does not carry the tool name or args — so to call a tool's `presentResult` the bridge keeps a small per-session map from `callId` to the in-flight call's `(name, args)`, populated on `tool/call` and removed as each result is presented (it holds only currently-in-flight calls, never finished ones). This is bridge-local state — NOT a change to the event schema or a core service. The map lives on the `SessionRecord`, so two concurrent sessions never cross their in-flight tool state; a `session/load` replay uses a throwaway presenter that pairs each `tool/call` with its `tool/result` as the log replays in order, so replayed tool cards render identically to live ones.

When you add an event to an `interface Events` block, its JSDoc MUST carry a `@mode emit|waterfall|parallel|serial` tag (the generator hard-errors without it): use `waterfall` when the signature ends with a `next: () => …` parameter (the listener transforms or vetoes via `next()`), `parallel` when the loop awaits a fan-out and must run every listener (e.g. an awaited `Promise | void` checkpoint like `session/flush`), `serial` when the loop awaits listeners in registration order and should isolate side effects (e.g. an ordered surface-mutation checkpoint like `agent/pre-step`; Cordis stops early if a listener returns a bail value, so `void` serial listeners must not return a semantic veto), and `emit` for plain fire-and-forget notifications. The generator also cross-checks the tag against the signature where the shape is conclusive (a trailing `next` ⇒ waterfall) and hard-errors on a contradiction.

Policy: [docs/i18n/README.md](../../../i18n/README.md); translation rules: [docs/i18n/translation-rules.md](../../../i18n/translation-rules.md); terminology source of truth: [docs/i18n/terminology.md](../../../i18n/terminology.md). -- **A blob-hash fingerprint makes freshness checkable.** The first line of every `.zh.md` records the repo-relative path and the first 12 hex digits of the git blob hash of the English source it renders.

The `required` list in [scripts/translation-pairing.manifest.json](../../../../scripts/translation-pairing.manifest.json) is a ratchet: each merged translation batch adds its files, so coverage only grows. +- **Paired sibling files with equal authority.** A documentation pair is three sibling files: English `foo.md`, Chinese `foo.zh.md`, and a consistency record `foo.i18n.yaml`. Neither language is canonical — a document may be authored and reviewed Chinese-first and translated to English afterwards, or the reverse; what binds the pair is that both sides must say the same thing, and pairs merge whole (both languages plus the record, never one alone). Policy: [docs/i18n/README.md](../../../i18n/README.md); translation rules: [docs/i18n/translation-rules.md](../../../i18n/translation-rules.md); terminology source of truth: [docs/i18n/terminology.md](../../../i18n/terminology.md). +- **A sidecar record of both blob hashes makes consistency checkable.** `foo.i18n.yaml` holds the full git blob hash of each side as of the last confirmed-consistent state. An edit to either side without re-confirming the pair is then mechanically detectable as a pure content comparison — no history lookup — and the hashes are computable for files edited in the same PR, which a commit-hash record is not. Re-recording (`verify-translation-pairing --write`) produces a reviewable yaml diff: confirming consistency is an explicit, visible act in the PR. +- **`verify-translation-pairing` joins `doc-sync`.** The gate ([scripts/verify-translation-pairing.ts](../../../../scripts/verify-translation-pairing.ts)) enforces: required pairs exist, every existing pair is complete (all three files) and consistent (both hashes match, switcher links both ways, structural signatures identical), and excluded (generated or bilingual-by-construction) files stay unpaired. The `required` list in [scripts/translation-pairing.manifest.json](../../../../scripts/translation-pairing.manifest.json) is a ratchet: each merged translation batch adds its files, so coverage only grows. - **Translation is agent work with human review.** The committed workflow is [.agents/skills/dsh-translate-docs](../../../../.agents/skills/dsh-translate-docs/SKILL.md), following the same pattern as [dsh-code-review](../../../../.agents/skills/dsh-code-review/SKILL.md): the skill carries the workflow and defers to the docs as sources of truth. ## Alternatives considered +- **English as the canonical source with a fingerprint inside the translation** — the design first proposed for this RFC: `.zh.md` files carried an HTML comment recording the English source's blob hash, and translation flowed EN → ZH only. Revised in review: the team wants Chinese-first authoring (write and review a Chinese RFC, then translate to English) with the two languages holding equal authority, which a one-directional canonical model cannot express. The sidecar record covering BOTH sides replaced the in-file one-directional fingerprint; the blob-hash mechanics survived unchanged. - **Locale directories (`docs/en/` + `docs/zh/`, the Kubernetes/ECharts model)** — rejected: this repo has no docs-site framework to map locales to routes, moving every English file would churn every existing cross-reference, and `verify-md-links`/`verify-doc-refs` would need path-mapping logic instead of working unchanged. - **A separate translation repo (the PingCAP `docs`/`docs-cn` model)** — rejected: right for a docs product with independent release trains, overkill for a monorepo's own documentation; it also puts the translation outside the reach of this repo's gates. -- **Interleaved bilingual files (single file, both languages)** — rejected: doubles every diff, breaks the one-line-per-paragraph convention's diff ergonomics, and makes partial staleness invisible. -- **Commit-hash fingerprints (MDN `l10n.sourceCommit`)** — rejected in favor of blob hashes: a same-PR source edit has no commit hash yet, so the MDN model cannot express "translated against the version this PR introduces", and verifying it requires git history instead of file content. -- **Comparing git timestamps of the pair (no fingerprint)** — rejected: formatting-only English edits would false-positive, and a translation committed after an unrelated English edit would false-negative; content identity is the only signal that means what the gate claims. +- **Interleaved bilingual files (single file, both languages)** — rejected: doubles every diff, breaks the one-line-per-paragraph convention's diff ergonomics, and makes partial inconsistency invisible. +- **Commit-hash records (the MDN `l10n.sourceCommit` model)** — rejected in favor of blob hashes: a same-PR edit has no commit hash yet, so the MDN model cannot express "consistent as of the state this PR introduces", and verifying it requires git history instead of file content. +- **Comparing git timestamps of the pair (no record)** — rejected: formatting-only edits would false-positive, and a counterpart committed after an unrelated edit would false-negative; content identity is the only signal that means what the gate claims. ## Industry precedent -Paired sibling files with locale suffixes are the dominant Chinese big-tech convention (ant-design `index.zh-CN.md`/`index.en-US.md`; arco-design `README.zh-CN.md` with a top-of-file switcher; Apache ShardingSphere's 387 `.cn.md`/`.en.md` pairs) — but none of those repos *enforce* pairing or freshness in CI; the convention holds by review alone. Freshness automation exists outside China: MDN's `l10n.sourceCommit` front-matter fingerprint, Vue's Ryu-Cho action (upstream-commit watcher that opens issues/PRs for stale translations), Kubernetes' localization drift scripts, and Microsoft's Azure co-op-translator (source-hash-driven LLM re-translation in CI). This design combines the two: the Chinese-ecosystem file layout with a fingerprint gate, plus a committed agent skill in place of a bot service. +Paired sibling files with locale suffixes are the dominant Chinese big-tech convention (ant-design `index.zh-CN.md`/`index.en-US.md`; arco-design `README.zh-CN.md` with a top-of-file switcher; Apache ShardingSphere's 387 `.cn.md`/`.en.md` pairs) — but none of those repos *enforce* pairing or consistency in CI; the convention holds by review alone.

This design combines the two: the Chinese-ecosystem file layout with a hash-pair gate, plus a committed agent skill in place of a bot service. ## Consequences -- Editing an English doc that has a `.zh.md` sibling obligates the same PR to update the translation — the gate makes the doc-sync rule bilingual, and CI (not reviewer memory) carries the invariant. -- Generated docs (`cordis-catalog/`, `tool-catalog/`, `module-graph.md`) are never paired; their generators emit English only, and the gate rejects a stray translation of them. -- Rollout is incremental by design: documents outside `required` are visible backlog (`--list`), not red CI, so translation lands in reviewable batches without a big-bang PR. -- The fingerprint doubles as the update tool (`git cat-file -p ` recovers the exact translated-from text for a minimal diff-based update), so re-translation of whole files is never forced by the mechanism. +- Editing either side of a paired document obligates the same PR to update the counterpart and re-record the pair — the gate makes the doc-sync rule bilingual, and CI (not reviewer memory) carries the invariant. +- Every pair adds a third file to the tree.

Write two full `spawn(...)` calls with literal tuples in an `if`/`else` (or a ternary between two complete calls), as [`dsh-bash-local`'s `run.ts`](packages/bash/bash-local/src/run.ts) does, so each branch's literal tuple keeps the typed overload.

Layer the cheap human/AI judgment on top, in the right order, and keep each unit of work honestly scoped — and lean on an independent agent to review for the class of defect gates structurally cannot catch (prose/RFC/comment drift, a bug introduced while fixing, a test that asserts nothing load-bearing). ## Architecture @@ -285,8 +279,6 @@ Each bullet is a bug class that bit us; the rule prevents the reoccurrence. - **A real-load-path test only GUARDS the export shape if a broken shape actually FAILS it.** The original crash (`cannot get property … without inject`) fired because that plugin HAS `inject`. A plugin with NO `inject` (a composition/bundle plugin that mounts children carrying their own inject, e.g. `dsh-agent-core` and the app packages) does NOT crash on a stray `export default` — `unwrapExports` silently drops `Config`/`name` and the plugin boots anyway — so a Loader smoke stays green while the export shape is broken. For such plugins add an EXPLICIT assertion that the regression fails: `expect('default' in mod).toBe(false)` plus running the module through the real `Loader.prototype.unwrapExports` and asserting `name`/`Config`/`apply` survive. Prove it: add `export default apply`, watch the test go red, revert. - **"Real entry path" means the PUBLISHED ARTIFACT, not the dev runtime.** A test (or a `demo:*` smoke) that boots `src/bin.ts` under `tsx` is NOT the same code a consumer runs — the package `bin` field points at the built `lib/bin.js` under plain `node`. tsx masks failure modes the published artifact has: a boot settle-race that exits 0 before the app's handles attach, module-resolution differences (the unbuilt `paths` map vs node_modules), and a load failure that `loader.await()`'s `Promise.allSettled` SWALLOWS so a typo'd config silently exits 0. The guard is a smoke that runs the built `lib/bin.js` under plain `node` in a node_modules-shaped temp dir (symlinked workspace + vendor packages), asserts the real output, AND asserts a genuinely-missing config exits NON-ZERO. The tsx demo is necessary but not sufficient; the published-bin smoke is what catches "green under tsx, broken on install". - **Tag spelling and EOF hygiene.** cordis.yml interpolates env via the `!!js` tag (js-yaml resolves custom tags under `tag:yaml.org,2002:js`), not `!js` — keep code, comments, and docs consistent. Files end with exactly one trailing newline; `git diff --check` (a pre-push gate) rejects new blank lines at EOF. -- **`child_process.spawn` narrows non-null `stdout`/`stderr` only from a LITERAL `stdio` tuple.** A ternary or variable in a `stdio` slot (e.g. `stdio: [wantStdin ? 'pipe' : 'ignore', 'pipe', 'pipe']`) selects the generic `spawn` overload, widening the child's streams to nullable — which then trips `no-non-null-assertion` (forbidden in `src`). Write two full `spawn(...)` calls with literal tuples in an `if`/`else` (or a ternary between two complete calls), as [`dsh-bash-local`'s `run.ts`](packages/bash/bash-local/src/run.ts) does, so each branch's literal tuple keeps the typed overload. This trap bit twice — recognize it the moment a conditional `stdio` slot appears. -- **`AgentLoop.create(id, options)` DROPS `options.meta` — only the programmatic factory `create` threads it.** The convenience `create()` prepares its session with a hardcoded `{ meta: {} }`; a test (or caller) that needs `session.header.cwd` or other header metadata to take effect must use the factory `ctx.agents.create({ agentId, sessionId, meta, agentOptions })` (which passes `meta: options.meta ?? {}`), or `resume` (which reloads the persisted header). `create` is synchronous; `resume` is async — it awaits the persisted load. A cwd-dependent test that silently sees an empty cwd is almost always the wrong creation path.

Move it to its own presentation.ts module so index.ts is the registry + execute waterfall and the presentation vocabulary is a separate, one-directional dependency. presentation.ts owns ONLY render-intent types and references none of the execution types; index.ts imports the view types for ToolDefinition's presentCall/presentResult signatures (clean acyclic index -> presentation). The opaque `meta` presentation channel (ToolExecuteReturn, ToolResult, ToolExecutionResult) is execution plumbing and stays in index.ts. Public surface unchanged: index.ts re-exports the vocabulary, so consumers (tool-fs/tool-bash/tool-web/tool-todo, the ACP bridge) keep importing from @deepseek-ai/dsh-tools with zero churn. No producer/bridge/test edits; a pure internal relocation with no observable-output change (snapshot goldens untouched). --- docs/cordis-catalog/events-and-services.md | 6 +- docs/core-data-structures/tools.md | 2 +- packages/core/tools/src/index.ts | 203 ++------------------ packages/core/tools/src/presentation.ts | 206 +++++++++++++++++++++ packages/core/tools/src/schema.ts | 3 +- 5 files changed, 230 insertions(+), 190 deletions(-) create mode 100644 packages/core/tools/src/presentation.ts diff --git a/docs/cordis-catalog/events-and-services.md b/docs/cordis-catalog/events-and-services.md index b3d784e6fa..6cf03aefe4 100644 --- a/docs/cordis-catalog/events-and-services.md +++ b/docs/cordis-catalog/events-and-services.md @@ -337,7 +337,7 @@ A tool was registered or unregistered (the available tool set changed).

[`dsh-hooks-claude`](../../../../packages/hooks/hooks-claude) (7 Claude Code hook points) and [`dsh-hooks-codex`](../../../../packages/hooks/hooks-codex) (5 Codex points) — map external hook commands onto the harness interception seams. They carry deep unit and coverage-spec coverage (every decision arm, every payload dialect, driven against a mocked seam) plus one key-gated e2e (`hooks.e2e.ts`, a live `PreToolUse` block). But the full-transcript snapshot tier — the one net that boots the real `acp-agent` subprocess, replays a recorded session keyless, and diffs the normalized ACP stdout + re-persisted log against committed goldens — covered exactly ONE hook: a Claude `UserPromptSubmit` block (`hook-prompt-block`). + +That is the tier a mocked unit test structurally cannot be: it exercises the REAL bridge translating a REAL hook process's outcome into the REAL seam decision, then the REAL loop's reaction, rendered exactly as an editor sees it. A bridge-translation or loop-structure regression that left every unit green would still escape it for every hook point but one — and for the Codex bridge, the ACP example did not even LOAD it, so no Codex hook could fire end-to-end at all. + +## Decision + +Two coupled changes, in one PR: + +### 1. The ACP example ships BOTH hook bridges + +`examples/acp-agent/cordis.yml` and `cordis.snapshot.yml` now load `dsh-hooks-codex` alongside `dsh-hooks-claude`, each pointed at its own config file (`./hooks.json` for Claude, `./codex-hooks.json` for Codex — the two dialects cannot share one file). This is a genuine product-surface change, not test-only wiring: the shipped ACP server (and the `demo:acp` front door) now carries both bridges. + +It is safe because a bridge whose config file is absent is a **silent no-op**: `apply()` catches the read failure, logs through `ctx.logger`, and registers nothing — zero listeners, zero session events. The `acp-agent` app ships no stdout logger, so the warning cannot reach the ACP JSON-RPC channel. A scenario (or a real project) that wants only Claude hooks ships only `hooks.json`; the Codex bridge sees no `codex-hooks.json` and vanishes. This was verified empirically: with both bridges loaded, all pre-existing snapshots (none of which ship a `codex-hooks.json`) are byte-identical. + +Loading both is the minimum that lets the snapshot tier exercise each dialect against the same real app the product ships. Recording (which boots `cordis.yml`) must load both too, so a recorded Codex scenario captures the transcript with its hook genuinely active — hence the symmetric edit to both configs. + +### 2. A snapshot scenario per hook point × its headline outcome, both dialects + +Thirteen scenarios under `examples/acp-agent/tests/snapshots/`, naming `hook---`: + +- **Authored, no model turn** (keyless, no sidecar — the derived replay script is empty; the `rejected` turn carrying `hook/*` events is compared): `hook-cc-promptsubmit-block`, `hook-codex-promptsubmit-block`. +- **Recorded against the real API, hook active during recording** (the model's reaction to the decision is part of the captured transcript, replayed keyless thereafter): `hook-{cc,codex}-promptsubmit-context` (allow + additionalContext fold), `hook-cc-pretool-deny` / `hook-codex-pretool-block` (deny → `isError` tool result), `hook-cc-pretool-ask` (ask → degrades to deny with the approval-required reason), `hook-{cc,codex}-posttool-block` (block with feedback), `hook-{cc,codex}-posttool-context` (accept + additionalContext), `hook-{cc,codex}-stop-continue` (a blocking Stop hook forces one extra step via steering). + +Each hook command emits only FIXED LITERAL strings (no timestamps/pids/`$RANDOM`/cwd echoes); the snapshot normalizer scrubs the one volatile field a `hook/result` carries (`durationMs`). The `Stop` scenarios self-limit with a marker file (`.stop_fired`) so the force-continue does not loop — the `stop_hook_active` loop-guard is still a bridge `TODO`, so an unconditional Stop hook would force-continue every step. + +### Three hook points are deliberately NOT snapshotted + +Discovered while building the matrix, and documented here because the omission is a decision, not an oversight: + +- **`SessionStart` and `SubagentStart`** inject context through a detached, best-effort `void runPoint(...).then(agent.inject())` with NO turn binding. The resulting `context/message` races the work it precedes (the first model request / the child's first turn) and lands at a nondeterministic log position. A recorded golden does not even reproduce on its own replay — a 10× replay stability check failed 10/10 for both. They stay on the bridges' unit coverage, which drives the seam directly without the timing race. (If the injection is ever made turn-bound and deterministic — the direction the `TODO(session-start-gating)` points — these become snapshottable.) +- **`SubagentStop`** is observe-only: its `subagent/end` handler passes no turn (so no `hook/*` log events) and does no injection. It writes NOTHING to the transcript, so a golden would be byte-identical to the no-hook run and could never be proven to fail — a guard that cannot bite. It stays on unit coverage (`bridge.spec.ts` already asserts the observe-only call). + +The matrix therefore covers every hook point that has a DETERMINISTIC, OBSERVABLE transcript footprint, for both dialects. + +## Consequences + +- Every bridge seam mapping with an observable transcript is now guarded at the full-transcript tier, in the real app, for both dialects — including the Codex bridge, which had no end-to-end coverage at all. Recorded goldens capture the model's real reaction to a denied/blocked/force-continued turn, which a hand-authored transcript could only guess at. +- The block scenarios are keyless (no model turn); the rest replay keyless from recorded fixtures. `pnpm run test:snapshot:record` regenerates the recorded fixtures from the live API and self-skips without a key like every recorded scenario. +- The prove-red discipline holds: tampering a hook config's output (e.g. changing a deny reason) turns its scenario red on replay — the hook process runs FOR REAL during replay (only the model is replayed), so the golden guards the actual hook→seam→loop path, not a mock of it. +- The `acp-agent` demo now loads a Codex bridge it will usually no-op (no `codex-hooks.json` in a typical project), which is the intended fail-soft behavior, not a cost. diff --git a/examples/AGENTS.md b/examples/AGENTS.md index c7219d3a18..488083b438 100644 --- a/examples/AGENTS.md +++ b/examples/AGENTS.md @@ -21,6 +21,6 @@ A keyless smoke that spawns the example from a temp cwd must set `TSX_TSCONFIG_P |---|---|---| | `echo-agent` | `tests/echo.e2e.ts` — boots the real `cordis.yml`, drives the echo tool round-trip and the direct canned reply | **N/A — keyless by nature** (the `mock-echo` model has no real provider) | | `coding-agent` | `tests/keyless-smoke.e2e.ts` — boots the full real tree (dummy key, no prompt → no model call), asserts banner + clean exit | `tests/{full-loop,coding-task,resume,compaction,todo-write}.e2e.ts` — real model + real bash + real todo_write, world-verified | -| `acp-agent` | `pnpm run test:snapshot` — boots the real ACP subprocess and replays a recorded session keyless (incl. `hook-prompt-block`, where a `UserPromptSubmit` hook blocks the prompt); `tests/acp.e2e.ts` also asserts stdout purity without a key | `tests/acp.e2e.ts` — real ACP prompt, verifies a file the agent wrote; `tests/hooks.e2e.ts` — a real `PreToolUse` hook blocks bash, verifies the file is NOT written | +| `acp-agent` | `pnpm run test:snapshot` — boots the real ACP subprocess and replays a recorded session keyless (incl. the hook matrix: a scenario per hook point × outcome for BOTH the Claude and Codex bridges — block, deny, ask, context-fold, force-continue); `tests/acp.e2e.ts` also asserts stdout purity without a key | `tests/acp.e2e.ts` — real ACP prompt, verifies a file the agent wrote; `tests/hooks.e2e.ts` — a real `PreToolUse` hook blocks bash, verifies the file is NOT written | See [the root AGENTS.md](../AGENTS.md) for repo-wide conventions and [docs/architecture.md](../docs/architecture.md) for the design. diff --git a/examples/acp-agent/cordis.snapshot.yml b/examples/acp-agent/cordis.snapshot.yml index aa65e540b4..a6a2b1f900 100644 --- a/examples/acp-agent/cordis.snapshot.yml +++ b/examples/acp-agent/cordis.snapshot.yml @@ -98,3 +98,14 @@ name: '@deepseek-ai/dsh-hooks-claude' config: configPath: ./hooks.json + +# The Codex hook bridge, loaded alongside the Claude one (symmetric with +# cordis.yml so a recorded Codex scenario fires the hook during recording too).

Start here, then keep going acr - **Seam discipline.** New swappable capability? Check it's split per the capability-seams RFC (interface / impl / consumer), and that the consumer injects the interface key, never an implementation type. - **Test quality — sufficiency, not just coverage.** 100% per-file coverage and a green suite are necessary, not sufficient: they prove the lines *ran*, not that the feature *works the way it ships*. Judge whether the tests are sufficient on two axes. (1) **Would they fail if the behavior regressed?** A test that passes but asserts the wrong thing — or restates the implementation instead of the contract (events fired, disposal reached, the world changed) — is worse than none. (2) **Do they exercise the REAL thing, the way it's actually used?** Prefer the genuine collaborator over a fake, drive the change through its real entry path (the cordis Loader, the ACP bridge, a booted subprocess — not a hand-built `ctx.plugin({...})` that bypasses `unwrapExports`), and verify the WORLD (re-read the file/log/registry externally), not the agent's self-report. A test that fakes the inputs just enough to cover every line will agree with whatever the author assumed; the real thing won't. When a test sets up a *clean/happy* path to reach a line, ask whether the line's PURPOSE is exercised — e.g. a durability/teardown path "tested" by a fully-completed turn never proves the mid-flight teardown it exists for; a torn-tail recovery branch covered by a well-formed log never proves recovery. Flag tests that hit the line but not the scenario. See AGENTS.md § Defensive patterns "Line coverage is not behavior coverage" and "Prefer the REAL implementation over a mock/stand-in in tests". - **Snapshot coverage for transcript/UX changes.** If the PR changes the editor-facing transcript or end-to-end agent UX — the ACP bridge's event→update translation, the agent loop's observable output, tool presentation, or anything an editor renders — it must add or update a snapshot scenario (`examples/*/tests/**/*.snapshot.ts`, goldens under `examples/acp-agent/tests/snapshots/`) or note explicitly why none applies (AGENTS.md § Conventions). Review the golden diff itself: a changed `stdout.golden.txt` / `session.golden.txt` is a behavior change in disguise — confirm it's intended, not an accidental regression someone re-recorded away. A pure internal refactor with no observable-output change is exempt, but the PR should say so. See [docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md](../../../docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md). +- **Bilingual docs: review translation quality, not just pairing.** If the PR adds or edits a doc pair, read the changed English and Chinese sides and compare the meaning, not only the mechanical diff. Verify terms against [terminology.md](../../../docs/i18n/terminology.md), including first-occurrence annotations and "do not translate as" prohibitions; if a new term has no established precedent, the PR should keep it in English, list it under `待定术语`, and update the terminology table once the rendering is decided. A green `verify-translation-pairing` only proves hashes, switchers, and structure were recorded — it does not prove the translation is faithful, natural, or correctly termed. Treat [translation-rules.md](../../../docs/i18n/translation-rules.md) MUST/MUST NOT violations as blocking. - **Intent and contracts.** Does the change do what the PR says, and honor the documented contract on *both* sides of every seam it touches (see AGENTS.md "Honor cross-seam contracts on BOTH sides")? ## How to respond From bae8bf49903b536f15d5dc479df53a371453d0c6 Mon Sep 17 00:00:00 2001 From: Tianyi Cui <53024+tianyicui@users.noreply.github.com> Date: Sat, 4 Jul 2026 00:54:31 +0800 Subject: [PATCH 098/168] scripts: lint only package directories --- scripts/publint-all.ts | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/scripts/publint-all.ts b/scripts/publint-all.ts index df13d87caa..0e06372c3f 100644 --- a/scripts/publint-all.ts +++ b/scripts/publint-all.ts @@ -1,5 +1,5 @@ import { execFileSync } from 'node:child_process' -import { readdirSync } from 'node:fs' +import { existsSync, readdirSync } from 'node:fs' import { resolve } from 'node:path' // publint every harness package.

Audited all nine RFCs + three supplements claim-by-claim against the merged tree (none invalidated; several strengthened): - prune-dead-core-spine-surface: describe the landed tools/pre-execute → dispatch → tools/post-execute pipeline — listeners return Decisions, the registry builds every result and snapshots it to protect callId, and a second (mutation-guard) test pins the field; drop the resolved wait-for-interception hedge; scope the additionalContext ferry out. - prune-producerless-vocabulary-variants: the ui-stdio fixture migrated off the continuation trigger (llm-replay is the sole writer now); the stack's own additions (rejected, prompt/blocked, hook/invoked+result) all arrived with producers — the admission policy demonstrated live. - prune-unimplemented-subagent-vocabulary: enrichment landed as lastAssistantMessage only (agentType was dropped in the stack's own review — the same judgment this RFC extends); the seam RFC now names tools/pre-execute deny, which exists, sharpening the re-add path. - drop-inert-request-knobs / drop-image-content-block / trim-acp-bridge-unreachable-surface: current-state rewordings (shipped bridges set no request fields; only compact-basic has explicit image arms; 13 hook goldens also pin agentInfo). - generic-long-running-tool-runtime census: second production seam consumer (hook-protocol runHook: resolve+run, stdin/env, foreground only — background machinery stays single-consumer); scrub-duplication blast radius. - discover-package-inventory: identical 54-entry tsconfig reference sets; the comparesLog scenario knob (fixture-derivable, like recorded). - unify-agent-and-session-id: third divergence site (in-process subagent children mint two UUIDs), the hooks bridge id-lookups, and ui-stdio's labelBySession map as a consumer that deletes under unification. New RFCs from the post-stack survey: - remove-agent-steering-mirror: the last mirror-of-durable event; zero production listeners; both retention RFCs deferred its fate, and the 'no durable twin' rationale is contradicted by the adjacent append. - tighten-hook-protocol-contract: producer-less 'native' dialect, parsed-and-discarded suppressOutput, and hook/result semantics (truncation + decision-string) defined twice in the bridges instead of the lib that owns the event. - single-source-acp-replay-config: cordis.yml/cordis.snapshot.yml differ by exactly one plugin entry, with no gate on the forced symmetry. --- docs/rfc/README.md | 3 ++ ...06-20-generic-long-running-tool-runtime.md | 2 +- .../2026-06-20-discover-package-inventory.md | 4 +-- .../2026-06-20-unify-agent-and-session-id.md | 7 +++-- .../2026-07-04-drop-image-content-block.md | 2 +- .../2026-07-04-drop-inert-request-knobs.md | 2 +- ...026-07-04-prune-dead-core-spine-surface.md | 10 +++---- ...-prune-producerless-vocabulary-variants.md | 8 ++--- ...prune-unimplemented-subagent-vocabulary.md | 4 +-- ...2026-07-04-remove-agent-steering-mirror.md | 28 ++++++++++++++++++ ...26-07-04-tighten-hook-protocol-contract.md | 29 +++++++++++++++++++ ...-04-trim-acp-bridge-unreachable-surface.md | 2 +- ...6-07-04-single-source-acp-replay-config.md | 26 +++++++++++++++++ 13 files changed, 107 insertions(+), 20 deletions(-) create mode 100644 docs/rfc/proposed/simplification/2026-07-04-remove-agent-steering-mirror.md create mode 100644 docs/rfc/proposed/simplification/2026-07-04-tighten-hook-protocol-contract.md create mode 100644 docs/rfc/proposed/testing/2026-07-04-single-source-acp-replay-config.md diff --git a/docs/rfc/README.md b/docs/rfc/README.md index d983022f33..72579726c0 100644 --- a/docs/rfc/README.md +++ b/docs/rfc/README.md @@ -60,6 +60,8 @@ Do NOT write one for a mechanical or local choice (a variable name, a one-file r | [Trim unreachable ACP bridge surface — the branding knobs and the kind-sniffing fallback](proposed/simplification/2026-07-04-trim-acp-bridge-unreachable-surface.md) | 2026-07-04 | | [Prune dead core-spine surface — `SurfaceManager.invalidate()`, the loop-internal exports, `ToolExecutionResult.callId`](proposed/simplification/2026-07-04-prune-dead-core-spine-surface.md) | 2026-07-04 | | [Share the app bins' boot glue instead of maintaining twin copies](proposed/simplification/2026-07-04-share-app-bin-boot-glue.md) | 2026-07-04 | +| [Remove the `agent/steering` mirror emit](proposed/simplification/2026-07-04-remove-agent-steering-mirror.md) | 2026-07-04 | +| [Tighten the hook-protocol contract — the `native` dialect, `suppressOutput`, and lib-owned `hook/result` semantics](proposed/simplification/2026-07-04-tighten-hook-protocol-contract.md) | 2026-07-04 | ### Architecture @@ -83,6 +85,7 @@ Do NOT write one for a mechanical or local choice (a variable name, a one-file r |---|---| | [Mutation testing as the coverage counterweight](proposed/testing/2026-06-11-mutation-testing.md) | 2026-06-11 | | [Deterministic tests, the replay invariant fixture, and race stress](proposed/testing/2026-06-11-deterministic-and-stress-testing.md) | 2026-06-11 | +| [Single-source the acp-agent replay config](proposed/testing/2026-07-04-single-source-acp-replay-config.md) | 2026-07-04 | ## Implemented diff --git a/docs/rfc/proposed/architecture/2026-06-20-generic-long-running-tool-runtime.md b/docs/rfc/proposed/architecture/2026-06-20-generic-long-running-tool-runtime.md index 87336a4868..7f7c5ed007 100644 --- a/docs/rfc/proposed/architecture/2026-06-20-generic-long-running-tool-runtime.md +++ b/docs/rfc/proposed/architecture/2026-06-20-generic-long-running-tool-runtime.md @@ -24,7 +24,7 @@ The runtime should own: ## Current seam consumption -A consumer census of the surface the runtime would carve up.

The false acp-agent analogy is replaced with the real distinction (protocol product surface vs one app's front-door scaffolding). - generate-rfc-index-tables — verified: the classification RFC records rejecting generation; the index tables are the repo's only systematically conflicting docs region. Process framing made timeless. Consolidated into existing owners: - web searchStatus()/fetchStatus()/WebCapabilityStatus (verified: zero production callers; the tool-web README and architecture.md claims are drift) → drop-web-providers-change-event, renamed drop-unconsumed-web-observation-surface. - hook/result.durationMs (unread, nondeterministic, normalizer-scrubbed) and the double-defaulted defaultTimeoutMs knob → tighten-hook-protocol-contract. - the exercised-but-unadvertised exec.arguments mutation path (a tool-bash integration shim rewrites through it) → a sanction-or-seal note in the pre-tool-input-rewrite proposal. - the dormant-guard critique of subagent depth machinery → recorded in prune-unimplemented-subagent-vocabulary as the considered-and-rejected alternative, with the keep sharpened (uncapped-today acknowledged; wiring the cap is the completion, not deletion). getProvider()/list() and lastAssistantMessage recorded as examined-and-kept (bash-revert precedent; observe-enrich recorded keep). Not ported (with reasons): - tools/change + system-prompt/change removal — recorded keeps in the adapter-change RFC, unengaged by the sweep; no new facts. - LlmService.models() — flagged by both surveys, but two lines with a plausible consumer: TODO-or-drive-by territory per the RFC bar, not a proposal. - SchemaProp.default RFC — already XXX(unused-default)-tagged; the RFC bar excludes TODO-tracked provisional cleanups. - PreToolDecision 'ask' removal — FIXME(permissions)-anchored deferral with the permission system as its named consumer. - Codex bridge Config.model, merged systemMessages — wire-faithful tested surface / README-documented deferral. Their in-code TODO notes (acp-test-harness, hook-snapshot-noise, catalog-type-links) and the stale hook-prompt-block name fixes ride the merge unchanged. --- docs/rfc/README.md | 9 +--

Both bridges write it; the ACP snapshot normalizer immediately scrubs it to `0` because wall-clock hook runtime is replay noise ([examples/acp-agent/tests/snapshot-normalize.ts](../../../../examples/acp-agent/tests/snapshot-normalize.ts)). The only remaining consumers are tests and generated goldens that exist because the field exists. Persisting a value that replay must erase is a smell: it is neither product behavior nor useful audit state. - -`MergedHookOutcome.systemMessages` is also unused. The codec should still parse `HookOutput.systemMessage` because the external protocols can emit it and both bridges warn when it appears, but the merged aggregate is never read; `rg "systemMessages|\\.systemMessages"` finds the merge helper, README prose, and merge tests only. The bridge already handles warnings per raw output before merge. - -Finally, both bridge configs carry optional process-level defaults that shipped configs do not set. `defaultTimeoutMs` duplicates the reference default (`600_000`) even though each command hook already has its own `timeout`; tests mostly cover schema-bypass fallback. `dsh-hooks-codex` also exposes `Config.model`, but the ACP configs load the Codex bridge with only `configPath`, and every hook payload already has an `Agent` whose `options.model` is the actual model for that run. - -## Proposal - -Remove the unused protocol and config surface while keeping the live external-hook behavior: - -- Change `HookDialect` to `'claude' | 'codex'` until a real native `hook/*` producer exists.

Link instead. +- Paragraph walls: one paragraph carrying several rules and parenthetical asides. Split it, or demote the detail to the linked home. +- Emphasis inflation: bold, CAPS, or "critically" everywhere means nothing stands out. Reserve emphasis for the clause that changes behavior. +- Spec-speak in `implemented/` RFCs: "should", migration plans, acceptance checklists. An implemented RFC describes what is, per [rfc/implemented/AGENTS.md](rfc/implemented/AGENTS.md). ## Cross-reference with machine-checkable links, never free prose -When one doc refers to another doc, an RFC, a package README, or any file in the repo, link it with a **relative Markdown link** to the actual path — `[capability seams](rfc/implemented/architecture/2026-06-13-capability-seams.md)`, `[architecture.md](architecture.md)`. Do NOT refer to it by bare prose or by a number ("see ADR 0009", "per RFC 005"): a number is not checkable, goes stale the moment a file is renamed, and forces the reader to go hunting. A relative link is verified mechanically — `pnpm run verify-md-links` (part of `doc-sync`, see [the cross-link lint RFC](rfc/implemented/process/2026-06-18-markdown-cross-link-lint.md)) fails CI and the pre-push hook if any relative target does not exist, so a rename that orphans a link is caught before review rather than rotting silently. +When one doc refers to another doc, an RFC, a package README, or any file in the repo, link it with a relative Markdown link to the actual path — never bare prose or a number ("see RFC 005"), which is uncheckable and rots on rename. `pnpm run verify-md-links` (part of `doc-sync`; see [the cross-link lint RFC](rfc/implemented/process/2026-06-18-markdown-cross-link-lint.md)) fails when a relative target does not exist, so a rename that orphans a link is caught before review. This is also why RFC files carry dates and topics instead of stable numbers: they survive moves between lifecycle and class folders without dangling references. -This is why the RFC tree carries no stable numbers: files are named `yyyy-mm-dd-topic-title.md` and referred to by link, so they survive moves between lifecycle folders (`proposed/`/`implemented/`/`rejected/`) and class folders without a dangling reference. When you move or rename a doc, the gate tells you every inbound link you still need to fix. - -The gate checks file *existence*, not `#anchor` validity — a link to a real file with a wrong heading fragment still passes. Prefer linking the file (and a heading when it helps the reader), but don't rely on the gate to catch a stale anchor. - -## RFCs - -Design decisions and proposals live in [rfc/](rfc/) — one kind of doc, grouped by lifecycle (`proposed/`/`implemented/`/`rejected/`) then by class (`feature`/`bug-fix`/`simplification`/`architecture`/`process`/`testing`). See [rfc/README.md](rfc/README.md) for the class definitions, the naming scheme, and when to write one. +The gate checks file existence, not `#anchor` validity — a stale heading fragment on a real file still passes, so verify anchors yourself when linking to one. diff --git a/docs/development.i18n.yaml b/docs/development.i18n.yaml index 4b9823584b..d8f76162db 100644 --- a/docs/development.i18n.yaml +++ b/docs/development.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

Every rule survives as one to three lines plus a link to its durable home; the stories, duplicate statements, and re-narrations go: - Situational clusters evict to new homes: docs/testing.md (tiers, with-key policy, real-over-mock, world-verification, real-entry-path guards), docs/defensive-patterns.md (the bug-class rules), and docs/cookbook/responding-to-pr-review-on-a-stack.md (the stacked-PR review procedure). - Doc-authoring rules consolidate into docs/AGENTS.md § Writing rules (current-state-never-history, md-wrap, ts-block compilation, @mode, catalog same-change, pair same-change). - packages/README.md drops to the group table + the extension-vs-bundle dependency rule; the hand ASCII graph yields to the generated module-graph.md; group READMEs are the canonical per-package map. - packages/AGENTS.md keeps only its packages-specific rules (export shape, ctx.get, real-Loader coverage); examples/AGENTS.md repoints its with-key-policy link; rfc/README.md loses a narrated-history aside; dsh-code-review / dsh-find-simplifications / verify-md-wrap references follow the moved content. - Budget manifest ratchets: AGENTS.md 8200 -> 1500 (now 1,495 words), packages/README.md 1900 -> 600, packages/AGENTS.md 600 -> 450; the two new eviction docs join the budget set (testing 800, defensive 550); docs/AGENTS.md raises 1000 -> 1250 for the absorbed writing rules (the one justified increase). The doc-tiers RFC's deferred list prunes the two items this change ships. --- .agents/skills/dsh-code-review/SKILL.md | 12 +- .../skills/dsh-find-simplifications/SKILL.md | 2 +- AGENTS.md | 333 ++++-------------- docs/AGENTS.md | 16 +- .../responding-to-pr-review-on-a-stack.md | 24 ++ docs/defensive-patterns.md | 27 ++ docs/rfc/README.md | 2 +- ...0-bash-stdin-env-trusted-plugin-surface.md | 2 +- .../2026-07-04-doc-tiers-and-budgets.md | 4 +- .../2026-06-20-public-agent-stop-surface.md | 2 +- docs/testing.md | 33 ++ examples/AGENTS.md | 2 +- packages/AGENTS.md | 16 +- packages/README.md | 113 +----- scripts/doc-budgets.manifest.json | 10 +- scripts/verify-md-wrap.ts | 2 +- 16 files changed, 200 insertions(+), 400 deletions(-) create mode 100644 docs/cookbook/responding-to-pr-review-on-a-stack.md create mode 100644 docs/defensive-patterns.md create mode 100644 docs/testing.md diff --git a/.agents/skills/dsh-code-review/SKILL.md b/.agents/skills/dsh-code-review/SKILL.md index 9dc4de5ca6..7740504998 100644 --- a/.agents/skills/dsh-code-review/SKILL.md +++ b/.agents/skills/dsh-code-review/SKILL.md @@ -22,8 +22,8 @@ Independent judgment governs *what to look at* and *how to apply a rule to this These define the conventions and gates this repo is checked against, and they are authoritative.

A stray default export makes the Loader's `unwrapExports` drop `inject` and the plugin crashes at load with `cannot get property … without inject` — invisible to hand-built `ctx.plugin({...})` tests and to line coverage. Confirm there's a test driving it through the REAL loader path (the no-key subprocess e2e for ACP is the model). And any opportunistic read of a service NOT in `static inject` should use `ctx.get(name)`, not `ctx.` (the property proxy throws through a foreign shadow).

Review the golden diff itself: a changed `stdout.golden.txt` / `session.golden.txt` is a behavior change in disguise — confirm it's intended, not an accidental regression someone re-recorded away.

No backward-compat shims, deprecation aliases, or re-export stubs. On-disk formats need no migrations — a backend REJECTS anything not at the current version. Two sanctioned version stances: monotonic bump-and-reject (the SQLite backend's `SCHEMA_VERSION`), and a pinned `0` that absorbs all shape churn (`SESSION_FORMAT_VERSION` in `dsh-session`, documented "no compatibility implied") so the instability stays explicit. Real version policy begins at the first release. -This extends to **on-disk formats, schemas, and stored data**: while unreleased there is no persisted user data to preserve, so a format/schema/contract change needs **no migration path** — a backend REJECTS anything not at the current version rather than upgrading it. How the *version number itself* behaves pre-release is a per-format choice between two equally-valid stances, and the repo uses both deliberately. **Monotonic bump-and-reject**: each breaking change increments the version — e.g. the SQLite backend's `SCHEMA_VERSION` bump that drops columns rejects any non-current `user_version` on open, with no migration; use it when a stored artifact has a small enumerable set of revisions worth telling apart. **A pinned `0` "unstable / pre-release" version**: the format stays at `0` and absorbs ALL pre-release shape churn without bumping, while a backend still rejects any non-`0` log — the session event log uses this (`SESSION_FORMAT_VERSION = 0` in `dsh-session`), because its shape changes often while unreleased and bumping on every tweak would dress up an unstable format as a sequence of stable boundaries that mean nothing yet; pinning `0` and documenting it "no compatibility implied" makes the instability *explicit* instead of pretending each revision is a real version. Either way there is no migration code, and either way a real monotonic policy begins at the first tagged release. A migration written now is a shim for data that does not exist. - -## Tests document behavior, not golden truth - -A passing test pins the behavior the code **currently** has — not necessarily the behavior it **should** have. Existing tests faithfully document existing behavior, but existing behavior is not automatically golden: it can be the residue of a past compromise, a half-built feature, or a limitation that no longer applies. So when a refactor or review makes you ask "can I change this?", a green test is **not** the answer — the question is whether the behavior the test pins is actually correct. - -Before you preserve a behavior solely to keep a test green, ask: is this behavior load-bearing (a real consumer depends on it, a contract promises it, a user observes it), or is it an artifact? If it's an artifact, **change the behavior AND its test together, in the same change, and say why in the PR** — do not contort new code to keep an obsolete assertion passing, and do not treat "but the test expects X" as a reason X must stay. Conversely, do not delete a test just because it is inconvenient: the discipline cuts both ways — you must show the *behavior* is dead, not merely that the test is in your way. - -The worked example is [Drop the mutable session summary](docs/rfc/implemented/simplification/2026-06-19-drop-mutable-session-summary.md): an entire `SessionSummary` type, a `SessionPersistence.update()` method, a JSONL sidecar, and SQLite columns existed and were exercised by their own contract test — yet **nothing in production CONSUMED any of it, and `update()` had no production caller**. (The backends did *write* summary state — JSONL touched the sidecar after a durable append, SQLite bumped `updated_at` in the append transaction — but those writes fed only reads that nothing performed.) The tests documented the behavior perfectly; the behavior was dead. Deleting the behavior and its tests together removed ~400 lines and erased a durability divergence the next refactor would have had to model. (This is the test-tier echo of "verify the world, not a synthetic stand-in" in § Defensive patterns: a test agrees with whatever it was written to assert; only a real consumer proves the behavior matters.) - -## RFCs are proposals, not golden truth - -The same discipline applies one level up, to the RFCs in `docs/rfc/`. A **proposed** RFC records an *intended* change argued at a point in time; it is not a contract to implement verbatim. The author reasoned from the code as they understood it then — and they can be wrong, or the code can have moved. So before implementing an RFC, **validate its premise against the current code first**: confirm the thing it wants removed or changed is actually dead/safe, and that the migration it proposes is genuinely cleaner than what exists. - -When carrying out the change fights back — a removal forces an awkward migration, deletes machinery that turns out to be load-bearing, or pushes consumers onto a more brittle hand-rolled equivalent — treat that friction as **evidence the RFC over-reached**, not as work to push through. Keep, split, or amend the change to match what the code actually wants, and say so in the PR. An RFC that ships in amended form gets its text amended on the way to `implemented/`, so the landed RFC describes what actually shipped rather than the original guess. The discipline cuts both ways: an RFC is also not a reason to *avoid* a change a maintainer would otherwise make — it is one input, weighed against the code in front of you. - -The worked example is [Keep one public stop primitive](docs/rfc/implemented/simplification/2026-06-20-public-agent-stop-surface.md): it proposed removing BOTH `Agent.abort()` and `Agent.whenIdle()` as redundant stop/quiescence surface. Validating against the code, `abort()` was genuinely dead — no production caller, the loop aborts its own `AbortController` directly — so it was removed as proposed. But `whenIdle()` was load-bearing: a deliberate quiescence primitive with live ACP consumers, and the RFC's suggested migration (observe the `running`→`idle` transition by hand) is exactly the brittle path § Defensive patterns warns against ("Async state is not synchronous state"). So only `abort()` shipped, `whenIdle()` stayed, and the RFC's text was amended on the way to `implemented/` to record the narrowed scope — the landed RFC is not a lie about what was built. - -## Orchestrating review feedback across a stacked PR chain - -A wave of review comments lands across several PRs in a dependent stack (`A ← B ← C …`) at once. Resolving it well is a discipline of its own, learned the hard way: - -- **One worktree per PR branch; never rewrite a pushed branch.** Each PR's fixes happen in that PR's own worktree. To bring a child up to date with a parent's new commits, **merge the parent down** — never rebase/amend/force-push a branch that is already pushed (see [§ Conventions](#conventions) "Never rewrite a pushed branch"). The stacked-merge graph and the per-round review-fix history depend on it. -- **A fix belongs on the PR that INTRODUCED the issue, then flows DOWN.** When a comment on PR `B` points at code `B` introduced, fix it on `B` and merge `B` into `C` — even if `C` already carries the same file through the chain. Originating the fix on the downstream `C` leaves `B` shipping the unfixed code and the fix invisible to a reviewer of `B`. (This bit us: a snapshot-test guard flagged on the lower PR got fixed only on the top PR, so the lower PR still read as unaddressed until the fix was relocated to its true origin and merged down.) -- **Each review fix is a SEPARATE commit, never an amend.** The "fix review findings" commit is part of the record — it shows what the review caught and how. Amending erases that. (Amend is fine only for your own not-yet-pushed work.) -- **Delegated work is trust-but-verify.** When sub-agents implement fixes in parallel, their report describes what they INTENDED, not necessarily what landed. Re-run the gates yourself on the actual tree, and for a regression guard, **prove it FAILS on the unfixed code** (introduce the regression, watch the test go red, revert) — a guard that passes both ways guards nothing. A sub-agent that "reframes the problem as already-handled" instead of fixing it is a signal to dig in personally, not to accept the reframing. -- **Triage on the merits, then reply in-thread.** Verify each comment against the code before acting (a reviewer flagging the right symptom can still mis-diagnose the cause — confirm both).

Do not ration real-API tests to save tokens: write many of them, cover the real flows (a real prompt that writes a file, a multi-turn conversation, tool use, cancellation mid-stream), and run them frequently while developing — locally and whenever you have a key in the environment. **Especially smoke tests**: a cheap with-key smoke test that boots the real example, sends one real prompt, and checks the world (a file on disk, a non-empty assistant turn) catches whole classes of "green unit tests, broken product" failures that mocks structurally cannot — the very gap that let the ACP inject bug ship (see [docs/postmortem/0001](docs/postmortem/0001-acp-default-export-drops-inject.md)). The self-skip rule is ONLY so CI (which has no secrets) stays green and so a contributor without a key isn't blocked — it is not a signal that real-API tests are expensive or second-class. When in doubt, add the with-key test AND run it. - -Dev/test/demo run **unbuilt** via tsx + the source `paths` map in the root `tsconfig.json` (`vitest` resolves through that same root config). Building is only needed for publishing/consumption outside the repo. Non-published code (`examples`, tests, and scripts) is checked by root `tsconfig.json`, which sets `noEmit` and references the package/vendor graph so those sources stay checked under their own tsconfig boundaries. +Real-API tests and demos read `DEEPSEEK_API_KEY` (and optional `DEEPSEEK_BASE_URL`) from the environment or a gitignored root `.env` loaded via `process.loadEnvFile()`. cordis.yml references env vars with the `!!js` tag (never `!js`). Never commit credentials. CI has no secrets, so e2e suites self-skip without a key — a CI accommodation, not a cost signal; the with-key policy is in [docs/testing.md](docs/testing.md). ## Conventions -- **Package naming**: every npm package in this repo is `@deepseek-ai/dsh-` (vendored packages keep their upstream names and are `private: true`). -- **ESM everywhere** (`"type": "module"`); imports between workspace packages use package names, never relative paths across package boundaries. In-package relative imports use explicit `.ts` extensions; `rewriteRelativeImportExtensions` turns those into `.js` in emitted JS, while declarations keep explicit `.ts` specifiers that NodeNext/Node16 TypeScript consumers can resolve to sibling `.d.ts` files. `lib/types/**/*.js` is a bundler-only intermediate, not a Node ESM entrypoint. -- **`cordis` is a peerDependency** (+ devDependency) of every harness package, mirroring upstream convention. -- **Registrations are effects**: anything a plugin contributes (adapter, tool, section, agent, event listener) goes through `ctx.effect()` / `ctx.on()` so disposal and HMR work. If you write a registry, `register()` must return the disposer. -- **Typed events via declaration merging**: services declare their events in `declare module 'cordis' { interface Events { … } }`, and their ctx key in `interface Context`. Extensible unions use the merge-extensible-map pattern (see `ContentBlockMap`, `MessageSourceMap`). -- **Waterfall semantics**: `ctx.waterfall` listeners receive `(...args, next)` and MUST call `next()` to delegate; returning without it short-circuits. This is the veto mechanism — use deliberately. -- **Discriminated unions: match, don't chain**: branch on a tagged union (`StreamChunk`, `FinishReason`, `SessionEvent`, …) with a `switch` on the tag, not a chain of `if (x.kind === '…')`. The switch narrows each arm so member-only fields (`finish.message`, `finish.code`) are reachable in the right case and a typo'd tag fails to compile. Prefer extracting a small typed helper (`finishError(finish: FinishReason)`) over inlining the branches at the call site. -- **Switch exhaustiveness**: switches over CLOSED unions (e.g. `StreamChunk`) end with `default: assertNever(value, 'context')` (from dsh-llm) so adding a variant breaks compilation at every switch that must handle it. Switches over MERGE-EXTENSIBLE unions (`SessionEventMap`, `ContentBlockMap`, `FinishReason`, …) must NOT use assertNever — plugin-added variants are valid unknown values; handle known cases and fall through `default` with a comment (the lint rule `switch-exhaustiveness-check` makes the choice explicit either way; a redundant disable directive is itself a lint error). -- **Plugins, not loop changes**: new behavior goes into a plugin on the documented extension seams (see the plugin sanity checklist in docs/architecture.md). Changing `agent-loop` requires updating that doc. -- **Capability seams are three packages**: when adding a swappable capability (an execution backend, a provider integration, …), split it into *interface* (abstract service + vocabulary types, e.g. `bash/`), *implementation* (a concrete subclass, e.g. `bash-local/`), and *consumer* (what the model/plugins see, e.g. `tool-bash/`). Implementations and consumers then evolve independently — a sandboxed executor replaces `bash-local` without touching tool schemas. The LLM seam follows the same shape (`llm/` is interface + consumer surface; adapters are implementations). See docs/architecture.md § "Capability seams" for when NOT to split. -- **Explicit > implicit at package seams**: interface/vocabulary types spell out every field a consumer must supply — no optional field that the implementation silently fills with a hidden `?? default`. Put defaulting in the owning implementation as an explicit step (a `resolve(request): Spec` method that turns the optional-field request into the required-field spec), not smuggled inside `run()`/`start()`. Example: `dsh-bash` splits `BashExecRequest` (optional `workdir`/`timeoutMs`, model-facing) from `BashExecSpec` (required, what `run`/`start` act on); the tool layer calls `ctx.bash.resolve()` between them. The reader of a `BashExecSpec` never has to wonder where the working directory came from. -- **Opaque cross-boundary ids are branded, never bare `string`**: an identity that crosses a package seam and that a consumer must store-and-return but never parse (a backend-defined version token, a target key, a task/session/call id) is a `Branded` from `@deepseek-ai/dsh-brand` with a same-named cast factory in the owning package — a zero-cost compile-time guard so semantically-distinct strings stop being interchangeable. Not every string needs it: author-readable names (`ToolName`) and closed code unions (`ErrorCode`) don't. See [Branded IDs everywhere they belong](docs/rfc/implemented/architecture/2026-06-20-branded-ids.md). -- **An empty `catch` must name what it swallows and why nothing else can hit it**: a bare `catch {}` hides bugs. When you deliberately ignore a throw, the comment must (a) name the single expected failure, (b) say why ignoring it is correct — usually because the useful state was already captured *before* the `try` — and (c) make clear nothing else of consequence can reach the catch (ideally the `try` wraps a single statement). Example: the error-body `response.json()` parse in `dsh-llm-deepseek`'s adapter sets `code` + HTTP `status` from the status line before the `try`, so a malformed provider body can only cost a richer message, never the real error. -- **Symmetry is usually more correct**: when two related values play parallel roles (a test fixture and its expected output, a request shape and its response shape, a buggy input and the test that checks the fix), give them parallel form — both named consts, or both inline, not one each way. Asymmetry is a smell that usually points at a missed extraction. -- **Merging PRs**: always merge with a **merge commit** (`gh pr merge --merge`), never squash or rebase. The per-PR commit history is intentional — review-fix commits, regression-test commits, and the reasoning in each message are part of the record — and squashing flattens it away. -- **Never rewrite a pushed branch in a stacked chain.** Once a branch is pushed (and especially once it has a PR), do NOT `rebase`, `amend`, or force-push it. Update a child branch by **merging its parent down** (`git merge ` into the child, as a new merge commit), never by rebasing the child onto the parent's new tip. Rewriting a shared branch diverges it from what the parent and GitHub recorded, which breaks the stacked-merge graph and erases the review-fix history that documents what each round caught. Amending is fine ONLY for your own not-yet-pushed, not-yet-reviewed work. A corollary on WHERE a fix lands: a review fix belongs on the PR that **introduced** the issue, even when a downstream PR in the stack also carries the affected file — fix it on the originating branch, then merge that branch DOWN the chain, rather than originating the fix on the downstream PR (where it would be invisible to a reviewer of the PR that actually owns the code). -- **TODO markers**: use `FIXME`/`TODO`/`XXX` to flag known issues by urgency — see [docs/development.md](docs/development.md) for the semantics of each. -- **Tests**: vitest, colocated under `packages///tests/*.spec.ts`. Every registry needs an HMR-safety test (dispose the contributing fiber, assert cleanup). **Excessive tests are welcome** — when in doubt, write the test; err on the side of covering edge cases, error paths, event ordering, and concurrency races even if they seem unlikely. Review findings get regression tests (see `packages/core/agent-loop/tests/review-fixes.spec.ts`). The same generosity applies to **real-API (with-key) e2e tests — inference is cheap here (we are DeepSeek), so do not ration them**: cover the agent's real flows (a real prompt that writes a file, multi-turn, tool use, cancellation) and run them frequently while developing, especially cheap **smoke tests** that boot the real example and check the world. A green mock/no-key suite proves the plumbing, not the product — the with-key smoke test is what catches "green units, broken product". See § Secrets / .env for the with-key policy and why self-skip is a CI accommodation, not a verdict that real-API tests are expensive. -- **Prefer the REAL implementation over a mock/stand-in in tests.** When the genuine collaborator is available in the repo, wire it up instead of hand-rolling a fake — a test that registers an inline `defineTool({ name: 'bash', … })` to stand in for `dsh-tool-bash` proves the *bridge* moves bytes but not that the *shipping tool* renders the way the test asserts; the two drift and the test passes while the product is wrong. Mock only the genuinely expensive/non-deterministic boundary (the LLM adapter, the network, the clock) and keep everything downstream real: a bridge tool-call test runs the scripted mock MODEL but the REAL tool + REAL executor (e.g. `makeBridgeHarness({ withBash: true })` plugs `dsh-bash-local` + `dsh-tool-bash` and runs an actual `echo`), so it verifies the actual `presentCall`/`presentResult` an editor sees. This is the unit-test echo of "verify the world, not a synthetic stand-in" (see § Defensive patterns) — a fake you wrote will agree with whatever you assumed; the real thing won't. -- **A change that affects the editor-facing transcript or end-to-end agent UX needs a snapshot test (or an explicit note in the PR why none applies).** The snapshot tier (`examples/*/tests/**/*.snapshot.ts`, `pnpm run test:snapshot`) boots the real example subprocess, replays a recorded session JSONL deterministically (keyless), and diffs the normalized stdout transcript + re-persisted session log against committed goldens — the full-transcript regression net that mock-level unit tests structurally cannot be (it is what catches a bridge-translation or loop-structure regression that leaves every unit green). When you change the ACP bridge, the agent loop's observable output, tool presentation, or anything an editor renders, add or update a scenario under `examples/acp-agent/tests/snapshots/` and re-record with `pnpm run test:snapshot:record`. Reviewing the golden diff is part of the review. The rule is scoped to transcript/UX-affecting changes — a pure internal refactor with no observable-output change does not need one, but say so. See [docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md](docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md). -- **A tool's editor/ACP representation is part of its design — decide it up front, not after.** When you add or change a model-facing tool, its ACP tool-call card is as much a deliverable as its `execute`: decide which render intent it declares via `presentCall`/`presentResult` (`generic` — a titled card with `kind`/`rawInput`/`content`/`locations`; `terminal` — a shell command; `diff` — a file create/modify rendered as an inline diff), and cover it with a snapshot test (the transcript tier is the only place card rendering is actually verified end-to-end — a unit test on the pure presenter proves the shape, not that an editor renders it). A tool that reads/writes files should almost always emit `locations` (for editor follow-along) and, for a mutation, a `diff` card; a tool that runs a command is a `terminal`. The presentation methods are pure functions of `args` (they run on live streaming AND session-log replay), so they must not do I/O or read session state — the bridge, not the tool, relativizes display paths and fills the session cwd. The reference implementations are `dsh-tool-fs` (generic/diff) and `dsh-tool-bash` (terminal); the vocabulary and the why are pinned in [docs/rfc/implemented/architecture/2026-07-02-tool-render-intent-union.md](docs/rfc/implemented/architecture/2026-07-02-tool-render-intent-union.md), and the step-by-step is in [docs/cookbook/adding-a-tool.md](docs/cookbook/adding-a-tool.md). When you introduce a new capability seam, a new agent-lifecycle shape, or anything that produces an observable transcript (a new tool family, a subagent transport, a new UI surface), the plan must name how it will be covered at EVERY tier it touches — unit, real-API e2e, AND the full-transcript snapshot tier — and, critically, must check that the existing test infrastructure can actually express that coverage. Do not assume a snapshot/e2e harness built for one shape (e.g. a single top-level ACP session) transparently supports a new shape (e.g. a parent agent driving nested child agents): verify it, and if it cannot, the harness extension is in-scope work to plan and schedule, not a detail to discover mid-implementation. This rule exists because a real plan under-scoped exactly this: the subagent backends were planned with unit + e2e coverage but the snapshot tier turned out to assume one session per process (`dsh-llm-replay`'s single positional cursor, single-file harvest), so nested-agent snapshot coverage became unplanned net-new infrastructure (`TODO(subagent-snapshots)`). The cost of finding that during design is a paragraph; the cost of finding it mid-build is a re-plan. When the harness gap is large enough to be its own reviewable unit, schedule it as a dedicated stacked follow-up with its own RFC — but SAY SO in the originating plan, with the gap named, rather than letting it surface as a surprise. +- Every npm package is `@deepseek-ai/dsh-`; vendored packages keep upstream names and are `private: true`. `cordis` is a peerDependency (+ devDependency) of every harness package. +- ESM everywhere (`"type": "module"`).

Read it before writing lifecycle, concurrency, subprocess, or teardown code. -- **Report orthogonal outcomes independently.** A result can be several things at once (a process can both time out AND exit 0 because it trapped the signal). Don't nest the report of one flag inside the branch of another. Surface each independent fact (`timedOut`, `signal`, `exitCode`) on its own so a caller never reads a cut-short run as a clean success. -- **Honor cross-seam contracts on BOTH sides.** When an interface documents two valid ways to signal something (e.g. an adapter may report a model failure by THROWING from `stream()` *or* by ending the stream with a `finish {kind:'error'|'aborted'}` chunk), the consumer must handle both — not just the one the first implementation happened to use. A library-backed adapter that can't throw mid-stream relies on the finish-chunk path; if the loop only catches throws, a provider 401 becomes a normal completed turn. Document the contract where the type is defined and exercise every branch through the real consumer in tests. -- **Async state is not synchronous state.** `agent.send()` does not flip status to `running` before it returns; a background task's completion races turn boundaries; `reader.close()` fires for both EOF and disposal. Never gate control flow on a status you only *just* requested. Drive lifecycle off the events/promises that actually fire (`agent/status`, `task.done`), and when "done" needs a settle signal, observe the transition (saw `running` THEN `idle`) rather than counting actions you assume map 1:1 to turns — the loop batches queued messages into one turn. But a settle-signal guard cuts both ways: if the awaited transition can *never* occur (EOF with no work submitted → no turn ever starts → never `running`), it hangs forever. Always handle the "nothing to wait for" branch explicitly alongside the "wait for the work" branch. -- **Dispose must reach quiescence, not just request it.** A teardown that issues kills/aborts but returns before the work stops leaves orphans. Make cleanup `async` and `await` the children's exit (kill → await `done`), and close listener/notification registries *before* killing so late completions stay silent. Tests must prove disposal *waited* (pid already gone right after `await fiber.dispose()`), not merely that the process eventually dies. -- **Contain callback exceptions at the boundary.** A user-supplied listener (`onTaskDone`, event handlers) that throws must not reject the promise it runs inside or starve the listeners after it. Wrap the dispatch loop in try/catch and log; never let one bad subscriber break core lifecycle. -- **Never hand untrusted/model output the ambient environment or predictable paths.** Spawned commands get a scrubbed env (drop `*KEY*`/`*SECRET*`/ `*TOKEN*`) so the harness's own credentials can't leak into output, `env`, or spill files. Temp/spill files use a private (0700) dir, random names, and exclusive owner-only (`'wx'`, `0o600`) opens — predictable world-readable paths invite symlink races and disclosure. -- **e2e tests own their resources.** Real-API/integration tests must create the harness in the test and dispose it in `afterEach` (even on failure/retry/timeout), so a flaky run doesn't leak processes or contexts. Shared fixtures live in a plain `tests/harness.ts` module, NOT another `*.e2e.ts` file — importing a spec file re-registers its `describe` and duplicates real API calls. Verify the WORLD, not the agent's self-report: re-run the command/check externally and assert files are byte-identical where they should be unchanged (a keyword probe lets a cheating agent pass). -- **Line coverage is not behavior coverage; test the REAL entry path, not a synthetic stand-in.** 100% per-file coverage and a green suite are necessary, not sufficient — they prove lines ran, not that the feature works the way it ships. A plugin shipped via `cordis.yml` is loaded by the cordis Loader, which calls `Loader.unwrapExports` (`exports.default ?? exports`) and then constructs a fiber from the module's `inject`/`name`/`Config` namespace exports. A test that mounts the plugin by hand-building `ctx.plugin({ name, inject, apply })` (or even `ctx.plugin(NamespaceImport)`) BYPASSES `unwrapExports` entirely, so it cannot catch a broken export shape. This bit us hard: a stray `export default apply` made `unwrapExports` collapse the module to the bare function, dropping `inject` — so every service read threw `cannot get property … without inject` the instant a real editor connected, while 178 hand-mounted tests stayed green. The guard is at least one test that drives the plugin through its REAL load path (a subprocess booting the example via the Loader, or the Loader API directly), exercising the headline operations end-to-end. It runs WITHOUT a key when the operation doesn't call the model (`session/new`/`session/load` reach the factory but never the LLM), so there is no excuse to skip it. Corollary: when an `*.e2e.ts` spawns the example from a temp cwd, set `TSX_TSCONFIG_PATH` to the repo-root tsconfig — the unbuilt `paths` map is found by searching UP from cwd, so a temp cwd outside the repo silently falls back to built `lib/`, which both hides source changes and only "works" when a stale build happens to exist. Two sharper corollaries this bit us with again: - - **A real-load-path test only GUARDS the export shape if a broken shape actually FAILS it.** The original crash (`cannot get property … without inject`) fired because that plugin HAS `inject`. A plugin with NO `inject` (a composition/bundle plugin that mounts children carrying their own inject, e.g. `dsh-agent-core` and the app packages) does NOT crash on a stray `export default` — `unwrapExports` silently drops `Config`/`name` and the plugin boots anyway — so a Loader smoke stays green while the export shape is broken. For such plugins add an EXPLICIT assertion that the regression fails: `expect('default' in mod).toBe(false)` plus running the module through the real `Loader.prototype.unwrapExports` and asserting `name`/`Config`/`apply` survive. Prove it: add `export default apply`, watch the test go red, revert. - - **"Real entry path" means the PUBLISHED ARTIFACT, not the dev runtime.** A test (or a `demo:*` smoke) that boots `src/bin.ts` under `tsx` is NOT the same code a consumer runs — the package `bin` field points at the built `lib/bin.js` under plain `node`. tsx masks failure modes the published artifact has: a boot settle-race that exits 0 before the app's handles attach, module-resolution differences (the unbuilt `paths` map vs node_modules), and a load failure that `loader.await()`'s `Promise.allSettled` SWALLOWS so a typo'd config silently exits 0. The guard is a smoke that runs the built `lib/bin.js` under plain `node` in a node_modules-shaped temp dir (symlinked workspace + vendor packages), asserts the real output, AND asserts a genuinely-missing config exits NON-ZERO. The tsx demo is necessary but not sufficient; the published-bin smoke is what catches "green under tsx, broken on install". -- **Tag spelling and EOF hygiene.** cordis.yml interpolates env via the `!!js` tag (js-yaml resolves custom tags under `tag:yaml.org,2002:js`), not `!js` — keep code, comments, and docs consistent. Files end with exactly one trailing newline; `git diff --check` (a pre-push gate) rejects new blank lines at EOF. +## Type safety and documentation -## Type Safety and Documentation +Everything compiles under `strict: true` with `noImplicitAny`; every remaining `any` carries a comment saying why a narrower type is infeasible. Lean toward the stricter lint rule and the extra mechanical gate: encode invariants in checks (`verify-*` scripts), preferring a narrow justified escape hatch over a rule left off globally. Type gymnastics are acceptable inside core packages when they buy plugin-author DX (the `defineTool` schema DSL is the canonical example). -This codebase aims to be **very type-safe and well documented** for maintainability. Code that fails to compile under `strict: true` (with `noImplicitAny` enabled for all `packages/*/*` source) is not acceptable. Every `any` that remains must have a specific justification (a comment explaining why a narrower type is infeasible). +Docs are part of every change: code changes update their README and JSDoc in the SAME change; a bilingual-pair edit updates the counterpart and re-records ([i18n contract](docs/i18n/README.md)). The writing rules — document the current state never the history, one physical line per paragraph, one home per fact — and the word-budget gate live in [docs/AGENTS.md](docs/AGENTS.md). -**Almost always lean toward the stricter lint rule.** In the agentic-coding era the cost/benefit of strictness has inverted: a machine writes and reads most of the code, so the one-time cost of satisfying a stricter rule is cheap and paid by a tool, while the benefit — a whole class of error caught mechanically, a consistent foundation every agent can rely on, less reviewer attention spent on what a linter could have caught — compounds across every future change. When choosing whether to enable a rule, tighten an existing one, or add a new gate (a `verify-*` script, a constraint check), default to YES unless it has a concrete, recurring false-positive problem. Prefer a narrowly-scoped escape hatch (a justified inline disable with a reason, a per-path override) over leaving the rule off globally. The same reasoning motivates this repo's many bespoke gates (`doc-sync`, `verify-package-paths`, the workspace-shape constraint): encode the invariant in a check so no human or agent has to remember it. +## Editing these instructions -In the **core** packages (`packages/llm/llm`, `packages/core/tools`, `packages/core/agent`, `packages/core/agent-loop`, `packages/core/session`, `packages/core/system-prompt`), **type gymnastics are acceptable when they improve the DX of plugin authors** for common plugin types. The `defineTool` typed schema DSL in `dsh-tools` is the canonical example: the `SchemaSpec` to `InferArgs` type-level mapping gives tool authors zero-cast typed `execute` args, and the cost of the conditional types stays inside the core package. +`AGENTS.md` is the real file; `CLAUDE.md` is a symlink to it (root, `packages/`, `examples/`). Edit `AGENTS.md`, never the symlink. This file is budget-gated (`verify-doc-budgets`): additions displace something or justify a ceiling raise in the PR. -Verbose documentation is fine **as long as docs and code stay strictly in sync**. Out-of-sync docs are worse than no docs. **When you change code, update its docs in the SAME change** — grep the package README and the module/JSDoc comments for the old behavior (config keys, defaults, error codes, wire field names, event names) and fix every hit. CI runs `pnpm run doc-sync` (`doc-typecheck` + `verify-cordis-catalog` + `verify-tool-catalog` + `verify-md-wrap` + `verify-md-links` + `verify-doc-refs` + `verify-package-paths` + `verify-rfc-classification` + `verify-type-equiv` + `verify-translation-pairing`), which typechecks every fenced `ts` block in `README.md`, `docs/**/*.md`, and `packages/*/*.md`, regenerates the cordis events/services catalog from source and fails if the committed copy is stale, asserts no hard-wrapped prose paragraphs, checks that every relative Markdown cross-link resolves, checks that every `docs/*.md` path cited in a source comment resolves, checks that every `packages/` reference naming a real package resolves, checks that every RFC is filed under a valid class folder and listed in its index, checks that every ` ```ts type-equiv ` doc block still matches its source type, and checks the bilingual pairing contract (required docs have a complete, consistency-recorded EN/ZH pair — see [docs/i18n/README.md](docs/i18n/README.md)) — across those files plus `AGENTS.md` / `packages/AGENTS.md` — but that scope does NOT catch prose drift in `AGENTS.md` / `packages/AGENTS.md` / `packages/README.md` (config keys, defaults, error codes), so keeping those in sync remains on the author. The same-change rule extends to translations: **editing either side of a paired doc means updating the counterpart and re-recording the pair in the SAME change** (run the [dsh-translate-docs](.agents/skills/dsh-translate-docs/SKILL.md) skill, then `pnpm run verify-translation-pairing --write`); the pairing gate goes red otherwise. Every module has a module-level doc comment explaining its role. Every exported class, interface, type, function, and non-obvious method has a JSDoc that explains semantics (not just the name) — contracts (what events fire when), disposal behavior, error behavior, and extension intent. Internal helpers get docs only where non-obvious. Prefer one-liners when one line suffices. +## Vendoring policy -**Tag every new event with `@mode`.** The cordis events/services catalog ([docs/cordis-catalog/events-and-services.md](docs/cordis-catalog/events-and-services.md)) is GENERATED from source by `scripts/gen-cordis-catalog.ts` — never hand-edit it; run `pnpm run gen-cordis-catalog` and commit the result. When you add an event to an `interface Events` block, its JSDoc MUST carry a `@mode emit|waterfall|parallel|serial` tag (the generator hard-errors without it): use `waterfall` when the signature ends with a `next: () => …` parameter (the listener transforms or vetoes via `next()`), `parallel` when the loop awaits a fan-out and must run every listener (e.g. an awaited `Promise | void` checkpoint like `session/flush`), `serial` when the loop awaits listeners in registration order and should isolate side effects (e.g. an ordered surface-mutation checkpoint like `agent/pre-step`; Cordis stops early if a listener returns a bail value, so `void` serial listeners must not return a semantic veto), and `emit` for plain fire-and-forget notifications. The generator also cross-checks the tag against the signature where the shape is conclusive (a trailing `next` ⇒ waterfall) and hard-errors on a contradiction. Write the rest of the event's JSDoc to stand alone — it is the catalog entry's prose. - -**The core-data-structures catalog is a maintained surface, not a write-once artifact.** [docs/core-data-structures/](docs/core-data-structures/core.md) catalogs the spine vocabulary (core.md) and the per-seam types (sub-pages). When a change adds, removes, or reshapes a type the catalog documents — a new `…Map` variant, a new content-block or session-event type, a field on `GenerateOptions`/`Agent`/`ToolDefinition`/a bash type, or a whole new core/seam type — update the catalog in the SAME change: edit the prose, and for a pasted ` ```ts type-equiv ` block, re-copy it verbatim and keep `scripts/type-equiv.manifest.json` 1:1 with the blocks. The `verify-type-equiv` gate catches a *drifted paste* of an already-documented type, but it canNOT tell you a brand-new core type was never documented — that judgment is on the author and the reviewer. The definition of "core" (the spine-vs-seam line) is in [core.md § What counts as "core"](docs/core-data-structures/core.md#what-counts-as-core); a genuinely spine-level new type belongs in core.md, a new capability's vocabulary on a sub-page. See [development.md](docs/development.md#documenting-types-verbatim-ts-type-equiv) for the `ts type-equiv` mechanics. - -**Document the CURRENT state — the "what" and "why" — never the PROCESS or HISTORY of how it got there.** A comment, JSDoc, or doc paragraph describes what the code *is* and why it is that way, as if it had always been so. Do NOT narrate the change that produced it: no "previously X, now Y", "changed from", "used to", "this replaces", "the old map", "renamed", "moved here", "as of this PR", or "(was …)". **In particular, NEVER name the change unit a reader cannot see — the PR, commit, or stack position that introduced the code — in a comment, JSDoc, OR a test name/description.** A `// (PR D's per-agent teardown)` aside, a `* Tests for the cancel primitive (PR C).` module doc, or an `it('… identity no longer matters')` title that only makes sense relative to a prior design are all the same violation: the reader of the current tree has no "PR D" or "old design" to anchor against, and the reference rots the moment the stack merges. Name the *mechanism* (`the session's AgentHandle teardown`), not the PR. Such phrasing rots the instant the next change lands, and a reader of the current code does not need the diff narrated in prose — that belongs in the commit message, the PR description, or an RFC (the durable home for "why we moved away from X"). Write "the owner token lives on the task in the executor" — not "ownership *now* lives on the executor instead of a plugin-local map". When a contrast genuinely aids understanding (a non-obvious choice between live alternatives), frame it against the alternative as a standing fact ("stored on the executor, NOT the tool plugin, so it survives an HMR reload"), not against the codebase's past. The same rule governs review-fix commits: the *commit message* records what the review caught; the *code comment* it touches states only the resulting truth. RFCs (`docs/rfc/`, grouped into `proposed/` / `implemented/` / `rejected/`) record the *why* behind choices a future reader would otherwise re-litigate (the vendoring policy, event-sourcing, the schema DSL are the existing examples). A PR that introduces such a decision — a new third-party runtime dependency over the vendoring default, a cross-package contract, a security/isolation model, a deviation from a documented architecture rule — writes the RFC in `implemented/` **in the same PR**, and links it from the relevant code. A proposal for future work not yet built goes in `proposed/`. A PR whose changes are mechanical, self-evident, or already covered by an existing RFC needs none — do not manufacture an RFC for a routine change. When unsure, the test is: would a competent maintainer six months from now ask "why was it done this way?" and be unable to answer from the code alone? If yes, write it. See [docs/rfc/README.md](docs/rfc/README.md) for the naming scheme and [docs/AGENTS.md](docs/AGENTS.md) for the cross-link convention. - -**Markdown is not hard-wrapped**: write one line per paragraph and let the editor soft-wrap. Hard line breaks mid-paragraph make docs harder to edit and diff — a one-word change reflows and re-diffs the whole paragraph. This applies to prose only: leave fenced code blocks, tables, and list structure intact (a wrapped list item folds to one line per bullet). Code comments / JSDoc are exempt — they stay under the linter's column limit. `pnpm run verify-md-wrap` (part of `doc-sync`) enforces this across `README.md`, `docs/**/*.md`, `packages/*/*.md`, and `AGENTS.md` / `packages/AGENTS.md`; `pnpm run verify-md-links` (also part of `doc-sync`) checks that every relative cross-link in those files plus `examples/**/*.md` and `.agents/skills/**/*.md` resolves. - -**Editing these instructions**: `AGENTS.md` is the real file; `CLAUDE.md` is a symlink to it (at the repo root and in `packages/` / `examples/`).

The rule constrains plugins that EXTEND the system, not the bundle that COMPOSES it — swapping the loop means publishing a different bundle, not rewiring every extension. +Dependency rule: extension plugins depend on interfaces, never on `dsh-agent-loop` (the loop is swappable); the sanctioned exception is the composition bundle `dsh-agent-core`, whose job is assembling the concrete spine ([full rule + generated graph](../packages/README.md#dependencies)). ## Service map -| ctx key | Class | Package | Role | -|---|---|---|---| -| `ctx.llm` | `LlmService` | dsh-llm | adapter registry; `stream()` | -| `ctx.sessions` | `SessionStore` | dsh-session | creates/holds event-sourced `Session`s | -| `ctx.sessionPersistence` | `SessionPersistence` (abstract) | dsh-session-persistence | durable persistence seam: create/append/load/list sessions | -| `ctx.systemPrompt` | `SystemPrompt` | dsh-system-prompt | ordered sections + tool schemas → `assemble()` | -| `ctx.tools` | `ToolRegistry` | dsh-tools | tool definitions; `execute()` through waterfall | -| `ctx.agents` | `AgentRegistry` | dsh-agent | live `Agent` handles + the create/resume factory seam (returns an `AgentHandle` = `{ agent, dispose() }` for owned per-agent teardown) | -| `ctx.agentLoop` | `AgentLoop` | dsh-agent-loop | creates `ReactLoopAgent`s and drives their loops | -| `ctx.bash` | `BashExecutor` (abstract) | dsh-bash | bash execution seam: foreground runs + background tasks | -| `ctx.fs` | `FileSystem` (abstract) | dsh-fs | filesystem provider seam: path resolution, stat, text read/stream, atomic writes/edits (optional version guard); owns the `fs/*` policy events | -| `ctx.compact` | `CompactService` (abstract) | dsh-compact | compaction seam: decide when history is too large, summarize an older range into a single surface node | -| `ctx.web` | `WebService` | dsh-web | web access seam: search/fetch provider registries, registration-order-independent selection, the `WebError` taxonomy | -| `ctx.subagents` | `SubagentService` | dsh-subagent | named provider registry for delegating a task to child agents | +| ctx key | Package | Role | +|---|---|---| +| `ctx.llm` | dsh-llm | adapter registry; `stream()` | +| `ctx.sessions` | dsh-session | creates/holds event-sourced `Session`s | +| `ctx.sessionPersistence` | dsh-session-persistence | durable persistence: create/append/load/list | +| `ctx.systemPrompt` | dsh-system-prompt | ordered sections + tool schemas → `assemble()` | +| `ctx.tools` | dsh-tools | tool definitions; `execute()` through waterfall | +| `ctx.agents` | dsh-agent | live `Agent` handles + create/resume factory (returns `AgentHandle { agent, dispose() }`) | +| `ctx.agentLoop` | dsh-agent-loop | creates and drives `ReactLoopAgent`s | +| `ctx.bash` | dsh-bash | bash execution: foreground runs + background tasks | +| `ctx.fs` | dsh-fs | filesystem provider: read/stream, atomic writes/edits; owns the `fs/*` policy events | +| `ctx.compact` | dsh-compact | compaction: detect pressure, summarize an older range | +| `ctx.web` | dsh-web | search/fetch provider registries + `WebError` taxonomy | +| `ctx.subagents` | dsh-subagent | named provider registry for delegating to child agents | -All registrations (`registerAdapter`, `section`, `tools`, `register`, …) go through `ctx.effect()` and return disposers, so plugin hot-reload (vendored HMR) and fiber disposal clean up automatically. - -For each service's full public interface (every method signature, generated from source), plus the inherited cordis-core/loader/hmr/timer surface a plugin also sees, see the `## Services` section of [cordis-catalog/events-and-services.md](cordis-catalog/events-and-services.md).

The bash capability is the template: +Swappable capabilities split into three packages — **interface** (abstract service + vocabulary, owns the ctx key), **implementation** (a concrete subclass loaded as a plugin), **consumer** (what the model and plugins program against) — so each evolves independently; the bash trio is the template ([capability seams RFC](rfc/implemented/architecture/2026-06-13-capability-seams.md)). Keep interface + consumer together when they are one concern (the LLM seam: `dsh-llm` carries both, adapters implement); don't split preemptively. -1. **Interface** (`dsh-bash`) — an abstract service plus the vocabulary types (`BashExecutor`, `BashRunResult`, `BashTask`, …). Defines the contract, owns the `ctx.bash` key, depends only on cordis. -2. **Implementation** (`dsh-bash-local`) — a concrete subclass loaded as a plugin (local subprocesses, process-group kills, spill-file truncation). Sandboxed, containerized, or remote backends are sibling packages implementing the same interface. -3. **Consumer** (`dsh-tool-bash`) — what the model and other plugins program against (the `bash`/`bash_output`/`bash_kill` tool schemas). Consumers `inject` the interface's ctx key and never import implementation types. +Two seams bend the template deliberately: -The LLM seam has the same topology folded differently: `dsh-llm` carries the interface (`LlmAdapter`) AND the consumer surface (`ctx.llm.stream()`), with adapters as implementation packages — there the consumer is the loop itself, not a swappable schema surface. Use the full three-package split when the consumer is independently replaceable; keep interface + consumer together when they are one concern. Don't split preemptively: a capability with one conceivable implementation and one consumer stays one package until proven otherwise. +- **Filesystem** adds a policy layer as an **event gate**, not a method service: `dsh-tool-fs` (the `read`/`write`/`edit` tools AND executor) dispatches `fs/*` intent events that `dsh-fs-policy` decides, so dropping the policy plugin degrades to the bare provider instead of breaking an injection ([event-gate RFC](rfc/implemented/architecture/2026-06-26-file-context-as-event-gate.md)). Paths resolve against the caller's session cwd, matching bash ([per-session cwd RFC](rfc/implemented/architecture/2026-07-02-fs-per-session-cwd.md)). +- **Web** folds search and fetch onto one seam: `ctx.web` is a provider REGISTRY (`registerSearchProvider`/`registerFetchProvider`, registration-order-independent selection); providers register like LLM adapters, and `dsh-tool-web` is the single consumer owning the tool schemas ([web seam RFC](rfc/implemented/architecture/2026-06-24-web-capability-seam.md)). -The filesystem capability follows the bash topology with a fourth layer, but the policy is contributed through an **event gate**, not a method service: `dsh-fs` owns the abstract `ctx.fs` provider seam (text IO + atomic mutation primitives whose version guard is optional) and the `fs/*` policy event vocabulary, `dsh-fs-local` provides the local backend, `dsh-tool-fs` is the model-facing `read`/`write`/`edit` tools AND the executor (it reads/writes/edits through `ctx.fs` directly, owns read windowing, dispatches the `fs/*` events), and `dsh-fs-policy` is a policy PLUGIN (no service) that decides the `fs/write-intent`/`fs/edit-intent` waterfalls and records on `fs/observed` to add observed-state + read-before-edit + version-guarded write/edit. Because the tool is not method-coupled to the policy, dropping `dsh-fs-policy` gracefully loses the policy and leaves the unconstrained bare provider rather than breaking the tool at a service-injection boundary. The demo agents (`coding-agent`, `acp-agent`) wire the full stack — `dsh-fs-local` + `dsh-fs-policy` + `dsh-tool-fs` — so `read`/`write`/`edit` are the default file surface (bash stays for shell/tests/search); the tools resolve a relative path against the caller's session cwd, matching bash ([the per-session cwd RFC](rfc/implemented/architecture/2026-07-02-fs-per-session-cwd.md)). See [the fs-policy event-gate RFC](rfc/implemented/architecture/2026-06-26-file-context-as-event-gate.md). - -The web capability uses the same three-package split but folds two capabilities onto one seam: `dsh-web` owns the abstract `ctx.web` service, which is a provider REGISTRY (`registerSearchProvider`/`registerFetchProvider`, registration-order-independent selection, the `WebError` taxonomy) rather than a single backend. Providers register capabilities, not tools — `dsh-web-search-exa`, `dsh-web-search-perplexity`, `dsh-web-search-deepseek`, and `dsh-web-fetch-local` each register into `ctx.web` the way an `LlmAdapter` registers into `ctx.llm`, so they are namespace plugins (`inject: ['web']`), not key-owning services. `dsh-tool-web` is the single consumer that owns the model-facing `web_search`/`web_fetch` schemas, prompt sections, and presentation; it reads only the aggregated `ctx.web.searchStatus()`/`fetchStatus()` and executes through `ctx.web.search()`/`fetch()`, so provider selection has one owner. Search and fetch are deliberately one seam (one thing to inject and configure, one selection policy, one abort/error vocabulary) despite sharing no request schema — see the [web capability seam RFC](rfc/implemented/architecture/2026-06-24-web-capability-seam.md). - -> **"Capability" — two unrelated meanings.** (1) The *seam pattern* above ("one plugin provides a capability, another needs it") is realized by plain Cordis **services + `inject`**: a provider registers a service (`ctx.bash`, declared in `interface Context`); a consumer declares `inject: ['bash']` and its fiber stays pending until the service exists, tearing down via HMR if it later vanishes. No extra library is needed. (2) `@cordisjs/plugin-capability` is a different axis entirely — a **permission/capability-security** service (named permissions with inheritance/dependency, tested against a session via `ctx.capability.test`). It is a candidate for the deferred permissions/sandbox work (the `tools/pre-execute` deny/ask gate), NOT a mechanism for swapping implementations. +> The seam pattern is plain Cordis services + `inject` (a consumer's fiber stays pending until the service exists). Despite the name, `@cordisjs/plugin-capability` is unrelated — a permission-security service (a candidate for the deferred permissions work), not a mechanism for swapping implementations. ## The vocabulary (dsh-llm) -Messages are arrays of typed **content blocks** (`text`, `reasoning`, `tool-call`, `tool-result`, `image`); the union is derived from the merge-extensible `ContentBlockMap`, so plugins can add block types via declaration merging. The same merge-extensible-map pattern is used for `MessageSource`, `FinishReason`, `TurnTrigger`, and `TurnEndReason` — typed sum types instead of strings. - -Streaming is a raw chunk protocol (`block-start`, `text-delta`, `reasoning-delta`, `tool-call-delta`, `block-end`, `usage`, `finish`). `BlockAssembler` is the single shared implementation that assembles chunks into blocks/messages; the loop logs raw chunks (replay fidelity) while feeding the same chunks through an assembler. - -`LlmAdapter` is the provider seam: subclass, implement `stream()`, call `ctx.llm.registerAdapter(models, adapter)`. Two real adapters implement it — `dsh-llm-deepseek` (hand-rolled fetch/SSE against the DeepSeek API) and `dsh-llm-pi-ai` (the same endpoint through the `@earendil-works/pi-ai` library). They exist as a pair deliberately: two independent internals over one contract verified the StreamChunk protocol, which is now documented (in `dsh-llm/src/types.ts`) with the conventions that review pinned down — usage before finish, nothing after finish, raw-string tool arguments, and the two sanctioned error paths (thrown vs `finish {kind:'error'}`). +Messages are arrays of typed **content blocks** (`text`, `reasoning`, `tool-call`, `tool-result`, `image`); the union derives from the merge-extensible `ContentBlockMap`; the same pattern types `MessageSource`, `FinishReason`, `TurnTrigger`, `TurnEndReason`. Streaming is a raw chunk protocol (`block-start` … `finish`) with `BlockAssembler` as the single shared chunk→block assembler; the loop logs raw chunks (replay fidelity) while assembling them. `LlmAdapter` is the provider seam: subclass, implement `stream()`, register via `ctx.llm.registerAdapter(models, adapter)`; `dsh-llm-deepseek` and `dsh-llm-pi-ai` implement the one contract as deliberate design twins ([twin RFC](rfc/implemented/architecture/2026-06-13-twin-llm-adapters.md)). The StreamChunk conventions (usage/finish ordering, raw-string tool arguments, the two sanctioned error paths) are pinned in `dsh-llm/src/types.ts` and [llm-streaming.md](core-data-structures/llm-streaming.md). ## Event-sourced sessions (dsh-session) -A `Session` is an append-only log of typed `SessionEvent`s — the single source of truth. The LLM message history is *derived* from the log (`deriveMessages()`): +A `Session` is an append-only log of typed `SessionEvent`s — the single source of truth. The LLM message history is *derived* (`deriveMessages()`): user/assistant messages, tool results, and envelope-tagged context/steering messages come from their events in chronological order (raw `assistant/chunk` events are replay/UI data, skipped; the per-event mapping is in [session.md](core-data-structures/session.md)). Replay/fork = `ctx.sessions.create(id, { seed })`; trace/telemetry = listen to `session/event` ([event-sourcing RFC](rfc/implemented/architecture/2026-06-11-event-sourced-sessions.md)). -- `user/message` → user message -- `assistant/message` → assistant message (raw `assistant/chunk` events are replay/UI data and are skipped in derivation; an empty-content `assistant/message`, which exists only to host a max-tokens step's `usage`, is skipped too) -- `tool/result` → user message carrying a `tool-result` block -- `context/message`, `steering/message` → user-role messages wrapped in a tagged envelope (`…`) at their chronological position — the "system-reminder" pattern; models distinguish them from real user prompts by the envelope. Live-adapter review has validated the tagged-envelope rendering against current DeepSeek behavior; provider-specific mismatches belong in that adapter. - -Replay/fork = `ctx.sessions.create(id, { seed: seedEvents })`. Trace/telemetry = listen to `session/event`. - -**Durability seam**: `session/event` is a synchronous notification; persistence plugins buffer (write-behind) and drain at the awaited `session/flush` checkpoint the loop fires at every turn end. The durable backend is a real **capability seam**: the abstract `SessionPersistence` service (`dsh-session-persistence`, `ctx.sessionPersistence`) defines create/append/load/list over the existing `SessionEvent` (no parallel persisted type), and `dsh-session-persistence-jsonl` is the first implementation — an append-only JSONL log per session with crash-safe atomic writes, crash recovery that PRESERVES an interrupted turn (closing it with a synthetic `turn/end {interrupted}` rather than truncating — a turn can be huge), and a read/replay path. Session metadata (format version, cwd, lineage, seed boundary) travels separately as `SessionHeader`, attached to a `Session` via `session.header`. Resuming a persisted session into a live agent is `ctx.agents.resume({ resumeSessionId })`. A second backend, `dsh-session-persistence-sqlite` (`node:sqlite`, one row per `SessionEvent` — the row shape `(session_id, seq, type, time, data, source_event_seqs, surface_op)` maps 1:1 onto it), passes the same `runPersistenceContract` suite, proving the seam is genuinely backend-agnostic. +**Durability**: `session/event` is a synchronous notification; persistence backends buffer write-behind and drain at the awaited `session/flush` checkpoint at every turn end.

The registry feeds its schemas into the system-prompt assembly automatically. - -`execute()` runs through a **two-waterfall pipeline** — `tools/pre-execute` (the allow/deny/ask gate) → core dispatch → `tools/post-execute` (inspect/replace the result, attach context) — the seams where sandbox, permission, hooks, and plan-mode plugins gate or transform a call. This maps Claude Code's validate → PreToolUse → permission → execute → PostToolUse pipeline onto two ordered waterfalls: `pre-execute` returns a `PreToolDecision` (allow/deny/ask), `post-execute` a `PostToolDecision` (accept/block, optionally replacing content or attaching `additionalContext`). Core dispatch sits between them as plain code, inside `execute`'s outer try/catch, with the tool body's own try/catch preserved so a thrown tool still reaches `post-execute` as an `isError`. - -**TODO**: tool shapes get revisited now that real tools exist (the bash suite landed; the `TODO(review)` in dsh-tools is still open) — e.g. a concurrency-safety hint for parallel execution; phase 1 executes tool calls sequentially. +`ToolRegistry.register()` takes schema + `execute()`; schemas flow into the assembly automatically. `execute()` runs through a two-waterfall pipeline — `tools/pre-execute` (a `PreToolDecision`: allow/deny/ask) → core dispatch → `tools/post-execute` (a `PostToolDecision`: accept/block, replace content, attach context) — the seams where sandbox, permission, hook, and plan-mode plugins live. A thrown tool still reaches `post-execute` as an `isError` result. ## Agents (dsh-agent) and the loop (dsh-agent-loop) -`Agent` is the handle every plugin programs against: +`Agent` is the handle every plugin programs against: `send()` (queued), `steer()` (mid-turn injection, drained between steps), `inject()` (in-session context; a one-shot `injection` turn when idle), `cancel()` (the single public stop primitive: clears queued + steering work, aborts the in-flight step, drops a turn about to start), `whenIdle()` (quiescence observation, not teardown), plus `session`/`status`/`options`. A lifecycle owner tears down via `await AgentHandle.dispose()` — stop, await exit, unregister. Full semantics: [core.md](core-data-structures/core.md), [lifecycle RFC](rfc/implemented/architecture/2026-06-18-agent-lifecycle-and-ownership-seams.md). -- `send(content)` — queued message; starts a turn when idle, else next turn -- `steer(content)` — mid-turn injection, drained **between steps**; behaves like `send` when idle -- `inject(content)` — in-session context (`context/message` event); the next request sees it (Claude Code attachment / system-reminder analog). An inject made while the agent is *running* joins the open turn; an inject while *idle* is wrapped in a one-shot turn (`turn/start{trigger:injection}` → `context/message` → `turn/end`) so every event stays turn-enclosed (see [the turn-enclosure invariant](rfc/implemented/architecture/2026-06-15-turn-enclosure-invariant.md)). -- `cancel(reason)` — the single public stop primitive: clears queued + steering work, aborts the in-flight step, and drops a turn about to start (the pre-step window) so a queued-but-not-started prompt never runs and cannot be batched into the cancelled turn. A UI/ACP `session/cancel` maps to it. -- `whenIdle()` — resolves once the agent reaches quiescence after settling out of `running` (resolves immediately when already idle; awaits the loop exit when disposed). A non-owner's quiescence-observation hook: it lets a consumer await the current work settling **without** disposing the agent. It is NOT teardown — it does not stop queued work, unregister the agent, or detach the session; a lifecycle owner tears an agent down with `await AgentHandle.dispose()` (which stops the loop, awaits its exit, and unregisters). -- `session`, `status`, `options` - -**Subagents**: `spawn`/`fork` are realized by the [`@deepseek-ai/dsh-subagent`](../packages/subagent/subagent) seam (a named-provider registry on `ctx.subagents`), not a method on `Agent`.

Out-of-process transports (ACP, and later A2A / Codex app-server / Claude Code SDK) register as sibling providers. See [docs/core-data-structures/subagent.md](core-data-structures/subagent.md) and [the subagent RFC](rfc/implemented/feature/2026-06-21-subagent-capability-seam.md).

When you add an event to an `interface Events` block, its JSDoc MUST carry a `@mode emit|waterfall|parallel|serial` tag (the generator hard-errors without it): use `waterfall` when the signature ends with a `next: () => …` parameter (the listener transforms or vetoes via `next()`), `parallel` when the loop awaits a fan-out and must run every listener (e.g. an awaited `Promise | void` checkpoint like `session/flush`), `serial` when the loop awaits listeners in registration order and should isolate side effects (e.g. an ordered surface-mutation checkpoint like `agent/pre-step`; Cordis stops early if a listener returns a bail value, so `void` serial listeners must not return a semantic veto), and `emit` for plain fire-and-forget notifications. The generator also cross-checks the tag against the signature where the shape is conclusive (a trailing `next` ⇒ waterfall) and hard-errors on a contradiction.

It asserts every file under a lifecycle folder lives in a class folder from the canonical set (a loose `.md` at a lifecycle root, or an unknown class folder, fails), and that `README.md` lists every RFC exactly once under the `###` heading matching its `{lifecycle}/{class}` path. The canonical class set lives as a `const` in this script — the machine source of truth — and [the index](../../README.md) documents it in prose; the two are kept in sync by hand (the README's completeness is gated, its class *descriptions* are not). This mirrors `verify-event-taxonomy`, which checks a doc table against source. +- **`scripts/verify-rfc-classification.ts`** — the closed set and index freshness. It asserts every file under a lifecycle folder lives in a class folder from the canonical set (a loose `.md` at a lifecycle root, or an unknown class folder, fails), and that the README's marker-delimited index regions byte-match a fresh render from the tree (see [generate the RFC index tables](2026-07-04-generate-rfc-index-tables.md)). The canonical class set lives as a `const` in `scripts/rfc-index.ts` — the machine source of truth shared with the generator — and [the index](../../README.md) documents it in prose; the README's class *descriptions* stay hand-written, its tables are generated. - **`scripts/verify-doc-refs.ts`** — source comments that cite docs. RFC paths are referenced not only from Markdown but from TypeScript doc comments (root-relative prose like `docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md`). `verify-md-links` never saw those, so the reorg could have silently orphaned them. This gate scans repo-authored `.ts` under `packages/**` and `examples/**` (excluding built `lib/` and `vendor/`) for `docs/….md` tokens, resolves each root-relative, and asserts it exists. It requires the `.md` extension so extensionless prose (`docs/postmortem/0001`, `docs/architecture.md § plugin checklist`) is left alone. ### Rejected alternatives - **A `Classification:` prose line** in each file (next to `Status:`), parsed by the gate. Workable, but it duplicates into the file a fact the path can already carry, and a line can disagree with its folder. Path-encoding makes the label and its storage the same thing — there is nothing to keep in sync. - **A `refactor` class.** It overlaps `simplification` almost entirely; the only discriminator anyone reached for was "does observable behavior change?", which `simplification` already encodes (it does not).

Rejected here to keep the index hand-written; superseded by [generate the RFC index tables](2026-07-04-generate-rfc-index-tables.md) once stacked proposal waves made the hand-written tables the repo's most conflict-prone docs region — the tables are now generated between markers while the surrounding prose stays curated. ## Consequences - Every RFC now sits under a class folder, and the index groups by class within each lifecycle. A reader scans one heading to see all simplifications, or all testing decisions. - Two more fast tsx scripts in the `doc-sync` chain; no new dependency (the mdast/GFM stack was already present for `verify-md-wrap`/`verify-md-links`). -- Adding a class is a deliberate act: amend the `const` in `verify-rfc-classification.ts` and the [Classification section](../../README.md#classification), not just `mkdir` a folder.

Zero production listeners existed — every steering consumer (hook bridges, goldens, deriveMessages) reads the durable event — and the one regression test subscriber asserted a fact the log already records. Remove the declaration (dsh-agent types + JSDoc list + README row), the emit in drainSteering (its ctx parameter goes too), and the emit line in the loop-pseudocode blocks (loop.ts module doc, architecture.md); the cordis catalog is regenerated. The regression test now pins source preservation on the durable steering/message event. Live-notification needs keep their surviving homes: agent/queued at enqueue time, session/event at drain time. RFC: docs/rfc/implemented/simplification/2026-07-04-remove-agent-steering-mirror.md (moved from proposed/, amended to shipped reality). The three implemented RFCs that stated the retention — the boundary-mirror removal, the stream-chunk removal, and event-domain-semantics — are amended to point at that RFC as the record of the removal, per implemented/AGENTS.md. The rejected retire-mid-turn-steering RFC keeps its frozen text (it records the declined proposal); the steering capability itself — steer(), the durable event, continuation forcing — is untouched. --- docs/architecture.md | 2 +- docs/cordis-catalog/events-and-services.md | 14 +-------- docs/rfc/README.md | 2 +- .../2026-06-30-event-domain-semantics.md | 4 +-- ...-20-remove-agent-boundary-mirror-events.md | 11 +++---- .../2026-07-02-remove-stream-chunk-mirror.md | 2 +- ...2026-07-04-remove-agent-steering-mirror.md | 30 +++++++++++++++++++ ...2026-07-04-remove-agent-steering-mirror.md | 28 ----------------- packages/core/agent-loop/src/loop.ts | 9 +++--- .../agent-loop/tests/review-fixes.spec.ts | 7 +++-- packages/core/agent/README.md | 3 +- packages/core/agent/src/types.ts | 9 ++---- 12 files changed, 53 insertions(+), 68 deletions(-) create mode 100644 docs/rfc/implemented/simplification/2026-07-04-remove-agent-steering-mirror.md delete mode 100644 docs/rfc/proposed/simplification/2026-07-04-remove-agent-steering-mirror.md diff --git a/docs/architecture.md b/docs/architecture.md index 0266f1a2e9..23e6f53db4 100644 --- a/docs/architecture.md +++ b/docs/architecture.md @@ -176,7 +176,7 @@ forever: session('tool/result') append buffered post-execute additionalContext → session('context/message')(s) ⟵ after ALL tool/results (adjacency) - drain steering → session('steering/message'); emit agent/steering + drain steering → session('steering/message') session('step/end') ⟵ durable step boundary (no agent/* mirror) cont = waterfall agent/turn-continuation(default = {action: hadToolCalls||steered ?

The mirrored-vs-live-only line the taxonomy actually draws puts it on the mirror side: `agent/queued` is genuinely live-only (it fires at enqueue time, before any durable event exists, and already carries a `steering: boolean` flag — cancelled queued work never enters the log), while `agent/steering` fires at the exact moment its durable twin lands, carrying nothing the log does not. - -Steering carries real production traffic — the hook bridges' turn-continuation decisions inject their reasons through `inbox.steer()`, landing as durable `steering/message` events that the hook-matrix goldens pin — and every one of those consumers observes the durable event. Nothing observes the mirror. - -## Proposal - -Remove the `agent/steering` declaration from `packages/core/agent/src/types.ts` (and its mention in the live-events JSDoc list there), the emit in `drainSteering` (whose `ctx` parameter becomes unused and goes too), the row in `packages/core/agent/README.md`, and the emit line in the loop-pseudocode blocks (`packages/core/agent-loop/src/loop.ts` module doc and [architecture.md](../../../architecture.md)); run `pnpm run gen-cordis-catalog`. Retarget the one regression test at the durable `steering/message` event — the source-preservation fact it pins lives on the log. The implementing PR amends the two retaining RFCs' scope lines per [implemented/AGENTS.md](../../implemented/AGENTS.md): the boundary RFC's retained-list entry and the stream-chunk RFC's "no durable twin" clause. - -## Why not keep it? - -"It is a control signal, not a boundary" — but the taxonomy's operative distinction is mirrored-vs-live-only, not control-vs-boundary, and this event mirrors. A consumer that wants enqueue-time notification has `agent/queued` (with its steering flag); a consumer that wants drain-time notification is by definition asking for the moment `steering/message` is appended, which `session/event` delivers with the same payload plus durability. The rejected [retire-mid-turn-steering RFC](../../rejected/simplification/2026-06-20-retire-mid-turn-steering.md) defended the steering *capability* — `steer()`, the durable event, continuation forcing — all of which this removal keeps untouched. - -## Acceptance criteria - -- No `agent/steering` spelling outside this RFC and the two amended RFCs; the catalog is regenerated and fresh. -- The retargeted test pins source preservation on `steering/message`; the suite is green. - -## Risks - -None known: zero production listeners exist to migrate, and both live-notification needs (enqueue, drain) have surviving homes (`agent/queued`, `session/event`). diff --git a/packages/core/agent-loop/src/loop.ts b/packages/core/agent-loop/src/loop.ts index 56c6cc1863..ef5c50b7ce 100644 --- a/packages/core/agent-loop/src/loop.ts +++ b/packages/core/agent-loop/src/loop.ts @@ -166,7 +166,7 @@ export interface LoopHandle { * → dispatch → tools/post-execute * session('tool/result') * append buffered post-execute additionalContext → session('context/message')(s) - * drain steering → session('steering/message'); emit agent/steering + * drain steering → session('steering/message') * session('step/end') ⟵ durable step boundary (no agent/* mirror) * cont = waterfall agent/turn-continuation ⟵ ContinuationDecision; default * {action: hadToolCalls||steered ?

Delete the dead mirror and the knob whose JSDoc claimed an override that did not exist; the remaining FsIoInternals knobs stay (the atomic-write tests use them). - FsTarget.inputPath: a "diagnostics only" field every backend and test fake had to fabricate, with zero production readers (policy and error messages use targetKey/displayPath). listDir gave children the bare entry name, which was nobody's input. - FsEditOutcome.replacements/.replaceAll: replacements had no reader (the single-match policy is enforced by the FS_AMBIGUOUS_EDIT / FS_EDIT_NOT_FOUND throws, whose message keeps the internal count); replaceAll only echoed the replace_all argument back to formatEditOutput, which now takes it from the parsed args. The outcome shrinks to { version, before, after }, parallel to FsWriteOutcome's backend-discovered fields. Emitted text is unchanged for both branches (no snapshot churn). - FileReadOutcome.limit/.version: formatReadOutput renders offset/lines/totalLines/truncatedByBytes only, and the fs/observed emit uses info.version directly. Backends shed four fabrication obligations and gain none. Doc pastes (core-data-structures/filesystem.md), the dsh-fs README resolve row, and the test fakes shrink with the types.

The app's front-door cluster always includes this UI and nothing else composes it, so the boundary bought manifest/tsconfig/module-graph/ README/publint surface for a helper that is not independently swappable — and a product app no longer depends on a support package documented as not-product-surface. createStdioChat, the StdioRuntime test seam, and both unit suites moved verbatim (imports rewired to the module path); the named name/inject/Config/apply export shape stays, being the contract the app's ctx.plugin mount consumes. Coverage stays per-file 100%; the built-bin smoke under plain node and both keyless Loader-path smokes prove the published artifact and the demos end-to-end.

It reads lines from stdin and feeds them to an agent (`send` when idle, `steer` while a turn is running), and renders that agent's streamed output and tool activity to stdout. A UI is "just a plugin" here — it consumes the `session/event` transcript feed plus a few `agent/*` control events (`agent/status`, `agent/created`/`agent/disposed`) and the `agents` service (`inject: ['agents']`), so the same plugin drives any example or product surface. - -This is a **convenience REPL for local testing and the demos, not a product surface** — its observable behavior is free to change. It is deliberately NOT treated as a load-bearing consumer when weighing whether a live event/API must exist: the boundary mirror events were removed precisely because "ui-stdio renders from them" is not a product constraint (it was migrated to `session/event`). The real product surfaces are the ACP bridge (`dsh-acp`) and the app packages. - -This package consolidates what were two near-identical copies under `examples/echo-agent` and `examples/coding-agent`.

(A multi-agent UI that needs per-agent panes would filter these handlers by the agent argument — deliberately out of scope here.) - -- `session/event` — the durable transcript feed drives ALL rendering, from a single listener so `inReasoning` transitions stay deterministic in append order: `assistant/chunk` writes the model's `text-delta` verbatim and wraps `reasoning-delta` in the dim SGR (`\x1B[2m … \x1B[0m`) so the chain-of-thought is visually subordinate to the answer (inert when no `reasoning-delta` chunks arrive, e.g. a mock model); `turn/start` prints a `[<agent> turn N]` header (the short agent label comes from a session-id→agent-id map seeded from `ctx.agents.list()` at install and kept live via `agent/created`/`agent/disposed`, since the turn event carries only the turn number); `turn/end` prints the trailing `> ` prompt; `tool/call` renders `[tool call] name(args)`; `tool/result` renders the joined text blocks as `[tool result] …`; and `todo/write` renders a glyphed checklist. - -## The I/O seam - -The production entry point `apply(ctx, config)` binds the real `process` streams.

Gating on an observed `running` here would hang forever. -- **Work submitted**: exit the next time the agent settles to `idle` *after* having been observed `running`. `agent.send()` does not synchronously flip status to `running`, so requiring an observed `running` first (`sawRunning`) avoids exiting in the gap before the turn starts and dropping work; and the loop batches several queued messages into one turn, so the exit keys off the idle transition rather than counting sends. - -Disposal (HMR or fiber teardown) closes the readline interface, which also fires `close` — a `disposed` guard ensures teardown never calls `process.exit`. - -## Plugin export shape - -Named `name` / `inject` / `Config` / `apply`, with **no default export**: the cordis Loader's `unwrapExports` does `exports.default ?? exports`, so a stray default would collapse the module to the bare function and drop the `inject` namespace (see [docs/postmortem/0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md)).

The only listeners/callers were the web packages' own tests, and the tool-web README / architecture.md prose claiming the tool 'reads only the aggregated searchStatus()/fetchStatus()' had drifted from the call sites. Remove the event declaration, both emits, and the rollback-before-emit machinery (the plain ctx.effect disposer keeps HMR cleanup, matching LlmService.registerAdapter). Remove searchStatus()/fetchStatus(), resolveStatus(), and WebCapabilityStatus; the provider-private status() stays as the execution-time selection input. Delete the listener-throw rollback test, and rewrite every event/status assertion across the web packages' tests onto caller-observable behavior: a successful search()/fetch() or the structured WEB_PROVIDER_* codes. Regenerate the cordis catalog; update the web/tool-web READMEs, the architecture.md web paragraph, core-data-structures/web.md, and the type-equiv manifest; amend the web capability seam RFC's facts to the shipped surface. This follows the llm/adapter-change precedent: a boot-time backend-registry signal and an availability probe distinct from executing both sit on the cut side of its keep/cut criterion.

To remove a web tool entirely, disable it here in config. -The tool reads only the aggregated `ctx.web.searchStatus()` / `fetchStatus()` for diagnostics — never each provider's `status()` directly — so provider selection has one owner. +The tool never calls a provider's `status()` and never enumerates providers — its only execution path is `ctx.web.search()` / `ctx.web.fetch()`, and provider unavailability reaches it as the structured `WebError` codes selection throws at execution time. Provider selection stays entirely inside the seam, with one owner. diff --git a/packages/web/tool-web/tests/tool-web.spec.ts b/packages/web/tool-web/tests/tool-web.spec.ts index 7af1ce7c36..7b3b965c46 100644 --- a/packages/web/tool-web/tests/tool-web.spec.ts +++ b/packages/web/tool-web/tests/tool-web.spec.ts @@ -187,9 +187,12 @@ describe('tool-web registration', () => { }) it('registers web_search even when no provider is available (schema follows enablement, not availability)', async () => { -

With no duration to measure, runHook loses its injected now clock and the single-field RunHookResult wrapper — it returns the HookOutput directly. The committed hook fixtures had the field stripped mechanically (field-only diff); the stdout goldens never carried it. - The bridges' double-defaulted defaultTimeoutMs config knob is replaced by one reference-default constant, DEFAULT_HOOK_TIMEOUT_MS, exported from the lib's runner and applied inside runHook; per-hook timeoutSec stays the override surface. - The hook/result semantics move into the lib that declares the event: HookResultRecord now carries the decoded HookOutput and appendHookResult derives the decision string (decision ?? stop-on-continue:false ?? pass) and the 500-char stderrSummary truncation; both bridges delete their byte-identical private copies. The snapshot suite passes against the existing goldens, proving the derived values are unchanged. - Rider: BLOCKING_EXIT_CODE is codec-internal again (zero importers). Amend the hook-protocol-lib and hook-snapshot-matrix RFCs to the new facts, update the lib/bridge READMEs and the session.md event tables, and retarget the affected unit tests (including new lib-level coverage of the derivation rules). --- docs/core-data-structures/session.md | 4 +- docs/rfc/README.md | 2 +- .../feature/2026-06-30-hook-protocol-lib.md | 6 +- ...26-07-04-tighten-hook-protocol-contract.md | 32 ++++++++++ .../2026-07-04-hook-snapshot-matrix.md | 2 +- ...26-07-04-tighten-hook-protocol-contract.md | 32 ---------- .../tests/snapshot-normalize.spec.ts | 16 ++--- .../acp-agent/tests/snapshot-normalize.ts | 10 +-- .../hook-cc-posttool-block/session.jsonl | 6 +- .../hook-cc-posttool-context/session.jsonl | 2 +- .../hook-cc-pretool-ask/session.jsonl | 2 +- .../hook-cc-pretool-deny/session.jsonl | 2 +- .../hook-cc-promptsubmit-block/session.jsonl | 2 +- .../session.jsonl | 2 +- .../hook-cc-stop-continue/session.jsonl | 4 +- .../hook-codex-posttool-block/session.jsonl | 10 +-- .../hook-codex-posttool-context/session.jsonl | 2 +- .../hook-codex-pretool-block/session.jsonl | 2 +- .../session.jsonl | 2 +- .../session.jsonl | 2 +- .../hook-codex-stop-continue/session.jsonl | 4 +- packages/hooks/hook-protocol/README.md | 10 +-- packages/hooks/hook-protocol/src/codec.ts | 6 +- packages/hooks/hook-protocol/src/events.ts | 43 ++++++++----- packages/hooks/hook-protocol/src/index.ts | 10 +-- packages/hooks/hook-protocol/src/runner.ts | 46 ++++++-------- packages/hooks/hook-protocol/src/types.ts | 25 ++++---- .../hooks/hook-protocol/tests/codec.spec.ts | 5 +- .../hooks/hook-protocol/tests/events.spec.ts | 63 ++++++++++++++++--- .../hooks/hook-protocol/tests/runner.spec.ts | 45 +++++++------ packages/hooks/hooks-claude/README.md | 3 +- packages/hooks/hooks-claude/src/index.ts | 26 +------- .../hooks/hooks-claude/tests/coverage.spec.ts | 9 +-- packages/hooks/hooks-codex/README.md | 3 +- packages/hooks/hooks-codex/src/index.ts | 24 +------ .../hooks/hooks-codex/tests/coverage.spec.ts | 4 +- 36 files changed, 233 insertions(+), 235 deletions(-) create mode 100644 docs/rfc/implemented/simplification/2026-07-04-tighten-hook-protocol-contract.md delete mode 100644 docs/rfc/proposed/simplification/2026-07-04-tighten-hook-protocol-contract.md diff --git a/docs/core-data-structures/session.md b/docs/core-data-structures/session.md index 900fdc54fa..fc2f40e1b8 100644 --- a/docs/core-data-structures/session.md +++ b/docs/core-data-structures/session.md @@ -228,8 +228,8 @@ A plugin may declaration-merge extra `SessionEventMap` types.

The committed hook fixtures (`session.jsonl`, which double as the expected-log goldens) had the field stripped mechanically; the stdout goldens never carried it. The bridges' `defaultTimeoutMs` config knob is replaced by one reference-default constant, `DEFAULT_HOOK_TIMEOUT_MS` (600 000 ms), exported from the lib's runner and applied inside `runHook`; `RunHookOptions` lost the field entirely, and the per-hook `timeoutSec` stays the override surface. The `hook/result` semantics live in the lib: `HookResultRecord` carries the decoded `HookOutput`, and `appendHookResult` derives `stderrSummary` (500-character truncation) and the decision string from it; both bridges deleted their private copies, and the derived values are byte-identical to what the bridges wrote (the goldens prove it — their only diff is the dropped `durationMs`).

Each returns trivially with its first real consumer (a transcript surface with hook stdout to suppress; a native-provenance feature that logs hook events; a trace viewer that reads timings — as live diagnostics or a deliberately durable telemetry event designed for it).

If one bridge drifts (a different cap, a different fallback), the shared durable event's semantics fork silently. - -## Proposal - -Narrow `HookDialect` to `'claude' | 'codex'` and fix its JSDoc; retarget the lib's one `'native'` test. Drop `suppressOutput` from `HookOutput`, the codec's parse lines, its codec-test assertions, and the parsed-superset lists in the lib README and [hook-protocol-lib RFC](../../implemented/feature/2026-06-30-hook-protocol-lib.md) (amended per [implemented/AGENTS.md](../../implemented/AGENTS.md)). Drop `durationMs` from `HookResultRecord`, `RunHookResult`, the `hook/result` event, the bridge appends, the docs/catalog, and the snapshot normalizer's special-case scrub (retiring `runHook`'s injected clock if nothing else needs it); the hook goldens refresh mechanically as the scrubbed field disappears. Replace the bridges' `defaultTimeoutMs` config knob with one shared reference-default constant in `dsh-hook-protocol` (per-hook `timeoutSec` stays the override surface). Move the `hook/result` semantics into the lib: `appendHookResult` (or a helper it exposes) derives `stderrSummary` and the decision string from the `HookOutput` + exit outcome, and both bridges delete their private copies. Rider: un-export `BLOCKING_EXIT_CODE` (zero importers; even the codec tests spell the literal `2`). - -## Why not keep them? - -The [hook-protocol-lib RFC](../../implemented/feature/2026-06-30-hook-protocol-lib.md) deliberately records "parses the full CC superset" — the strongest counterargument is that this proposal re-litigates decisions that RFC records. But parsing a field whose value can never influence anything is not protocol faithfulness, it is a reader trap; a dialect variant that the design's own thesis says will never be stamped is vocabulary without an interpreter; and durable telemetry that replay must scrub is a cost with no buyer. Each returns trivially with its first real consumer (a transcript surface with hook stdout to suppress; a native-provenance feature that logs hook events; a trace viewer that reads timings — as live diagnostics or a deliberately durable telemetry event designed for it). On item 5, the lib RFC chose per-bridge explicitness over a parameterized engine — but that choice governed payload construction and Decision mapping; the semantics of the SHARED durable event are precisely the "primitives where duplication would actually be dangerous" that the same RFC assigns to the lib. - -## Acceptance criteria - -- `HookDialect` is two-valued; `rg "'native'"` in the hooks packages returns only this RFC's amended references. -- `suppressOutput` and `durationMs` appear nowhere in source, parsed-field doc lists, the catalog, or the normalizer; the hook goldens are re-recorded or refreshed without the field. -- Both bridge configs lose `defaultTimeoutMs`; the reference default lives once, in the lib; per-hook `timeoutSec` still overrides it. -- One definition each of the truncation rule and the decision-string rule, in `dsh-hook-protocol`, exercised by both bridges' suites. - -## Risks - -The `dialect`, `suppressOutput`, `defaultTimeoutMs`, and semantics changes are invisible on the wire and in the goldens; the `durationMs` removal churns the hook goldens once (a mechanical refresh — the field was already normalized to a constant). The cost is churn in `dsh-hook-protocol` and both bridges — cheap under the pre-release stance, and cheaper than letting two copies of a durable event's semantics age apart. diff --git a/examples/acp-agent/tests/snapshot-normalize.spec.ts b/examples/acp-agent/tests/snapshot-normalize.spec.ts index bfe29af8a5..be540c9857 100644 --- a/examples/acp-agent/tests/snapshot-normalize.spec.ts +++ b/examples/acp-agent/tests/snapshot-normalize.spec.ts @@ -91,20 +91,14 @@ describe('normalizeSessionLog', () => { expect(out).toContain('{{sessionId}}') }) - it('zeroes a hook/result durationMs (run-to-run noise) but keeps its decision', () => { + it('leaves event data fields untouched beyond the time zeroing (no per-event field scrubs)', () => { const ev = JSON.stringify({ type: 'hook/result', seq: 2, time: 5, - data: { turn: 1, point: 'UserPromptSubmit', handlerId: 'h', decision: 'block', exitCode: 2, durationMs: 37 }, + data: { turn: 1, point: 'UserPromptSubmit', handlerId: 'h', decision: 'block', exitCode: 2 }, }) const out = normalizeSessionLog(`${header({})}\n${ev}\n`, ctx) - expect(out).toContain('"durationMs":0') - expect(out).not.toContain('37') - expect(out).toContain('"decision":"block"') // the decision is the behavior — kept - }) - - it('leaves a non-hook event durationMs untouched (only hook/result is scrubbed)', () => { - const ev = JSON.stringify({ type: 'tool/result', seq: 2, time: 5, data: { durationMs: 88 } }) - const out = normalizeSessionLog(`${header({})}\n${ev}\n`, ctx) - expect(out).toContain('"durationMs":88') + expect(out).toContain('"decision":"block"') + expect(out).toContain('"exitCode":2') + expect(out).toContain('"time":0') }) }) diff --git a/examples/acp-agent/tests/snapshot-normalize.ts b/examples/acp-agent/tests/snapshot-normalize.ts index 8150057fa4..db0d493535 100644 --- a/examples/acp-agent/tests/snapshot-normalize.ts +++ b/examples/acp-agent/tests/snapshot-normalize.ts @@ -8,8 +8,7 @@ * Scrubbed: `randomUUID()` session ids → `{{sessionId}}`; the temp `mkdtemp` * cwd → `{{cwd}}` (it appears in terminal-card `_meta` and the log header); * JSON-RPC request `id` → a stable per-transcript sequence; the log's per-event - * `time` (epoch ms) and header `createdAt` → 0; a `hook/result` event's - * `durationMs` (wall-clock hook runtime) → 0.

Hardcode agentInfo at the initialize site and delete the fields, their schema defaults, the ?? fallbacks, and the TODO(double-default) whose subject vanishes. The handshake wire value is unchanged (all snapshot initialize lines byte-identical). - The toolKindFor name heuristic special-cased bash*/read*/write/edit* names in the generic-fallback path, violating the bridge's own design rule ("the bridge never special-cases tool names"). Every first-party tool ships its kind via presentCall; the fallback now renders the neutral kind 'other'. The fallback is reachable when a presentCall throws OR when model args fail the tool schema (defineTool's presentCall wrapper returns undefined on violations) — the latter shows up in one committed golden (hook-codex-posttool-block: three bash calls missing the required description), whose kind cells flip execute->other. That 3-line golden refresh is the whole transcript delta. The empty-arguments branch of parseToolArguments lost its only exercise with the deleted heuristic test; it is live behavior (JSON.parse('') throws, so the guard is what renders a zero-arg call as rawInput {}), so it gets a dedicated pin instead of deletion. RFC moved to docs/rfc/implemented/simplification/ and amended to shipped reality: fallback reachability includes schema-invalid args, and the golden churn is exactly the three kind cells (the original zero-churn claim held only for the branding half). --- docs/rfc/README.md | 2 +- ...-04-trim-acp-bridge-unreachable-surface.md | 22 +++++++++++ ...-04-trim-acp-bridge-unreachable-surface.md | 27 -------------- .../stdout.golden.jsonl | 6 +-- packages/ui/acp/README.md | 6 +-- packages/ui/acp/acp-feature-support.md | 4 +- packages/ui/acp/src/index.ts | 37 +++++-------------- packages/ui/acp/tests/bridge.spec.ts | 9 ++--- packages/ui/acp/tests/stream-update.spec.ts | 24 ++++++------ packages/ui/acp/tests/turns.spec.ts | 5 ++- 10 files changed, 62 insertions(+), 80 deletions(-) create mode 100644 docs/rfc/implemented/simplification/2026-07-04-trim-acp-bridge-unreachable-surface.md delete mode 100644 docs/rfc/proposed/simplification/2026-07-04-trim-acp-bridge-unreachable-surface.md diff --git a/docs/rfc/README.md b/docs/rfc/README.md index d53684bf6b..e19a16e52b 100644 --- a/docs/rfc/README.md +++ b/docs/rfc/README.md @@ -62,7 +62,6 @@ Do NOT write one for a mechanical or local choice (a variable name, a one-file r | [Remove the `agent/steering` mirror emit](proposed/simplification/2026-07-04-remove-agent-steering-mirror.md) | 2026-07-04 | | [Share the app bins' boot glue instead of maintaining twin copies](proposed/simplification/2026-07-04-share-app-bin-boot-glue.md) | 2026-07-04 | | [Tighten the hook-protocol contract — dialect, discarded fields, double defaults, and lib-owned `hook/result` semantics](proposed/simplification/2026-07-04-tighten-hook-protocol-contract.md) | 2026-07-04 | -| [Trim unreachable ACP bridge surface — the branding knobs and the kind-sniffing fallback](proposed/simplification/2026-07-04-trim-acp-bridge-unreachable-surface.md) | 2026-07-04 | ### Architecture @@ -120,6 +119,7 @@ Do NOT write one for a mechanical or local choice (a variable name, a one-file r | [Stop mirroring durable boundaries as agent events](implemented/simplification/2026-06-20-remove-agent-boundary-mirror-events.md) | 2026-06-20 | | [Split the filesystem seam — provider text mutations plus the `dsh-fs-policy` plugin](implemented/simplification/2026-06-26-fsspec-style-fs-seam.md) | 2026-06-26 | | [Stop mirroring the token stream as an agent event](implemented/simplification/2026-07-02-remove-stream-chunk-mirror.md) | 2026-07-02 | +| [Trim unreachable ACP bridge surface — the branding knobs and the kind-sniffing fallback](implemented/simplification/2026-07-04-trim-acp-bridge-unreachable-surface.md) | 2026-07-04 | ### Architecture diff --git a/docs/rfc/implemented/simplification/2026-07-04-trim-acp-bridge-unreachable-surface.md b/docs/rfc/implemented/simplification/2026-07-04-trim-acp-bridge-unreachable-surface.md new file mode 100644 index 0000000000..3df0e0322a --- /dev/null +++ b/docs/rfc/implemented/simplification/2026-07-04-trim-acp-bridge-unreachable-surface.md @@ -0,0 +1,22 @@ +# RFC: Trim unreachable ACP bridge surface — the branding knobs and the kind-sniffing fallback + +Status: implemented (accepted 2026-07-04) + +## Problem + +Two pieces of `dsh-acp` surface were unreachable from any shipped configuration: + +1. **`AcpConfig.agentName` / `agentVersion`** (`packages/ui/acp/src/index.ts`).

**`@deepseek-ai/dsh-agent-core`** ([packages/core/agent-core](../../../../packages/core/agent-core)) — a Cordis bundle plugin for the providerless, executor-less, UI-less spine: `timer` + `llm` + sessions + system-prompt + tools + agents + invariants + `tool-bash` + `agent-loop`, mounted as child plugins inside its `apply(ctx)` via `ctx.plugin(...)`. This is the old `base-core.yml` **minus** `bash-local`, **plus** `timer` and the loop, as code instead of a YAML include. The bundle **forwards** `agent-loop`'s `agents` list as its own config (`export const Config = AgentLoop.Config`, default `[]`, the existing `AgentLoop.Config` shape in [packages/core/agent-loop/src/index.ts](../../../../packages/core/agent-loop/src/index.ts)) — so each app supplies its own pre-created agents. This is precisely the reason the old `base-core.yml` gave for keeping `agent-loop` *out* of the shared core ("the examples disagree — stdio needs a pre-created `main`, acp needs none"); forwarding the config dissolves that objection — the loop is shared, the agents list is per-app. The bundle children register into the root service store, so a leaf-mounted sibling (the adapter, the executor) sees them exactly as a nested `plugin-include` subtree's services were seen before. Depending on the CONCRETE `dsh-agent-loop` (not just the `dsh-agent` interface) is deliberate and is the sanctioned exception to the "extension plugins depend on interfaces, never on the concrete loop" rule (packages/README.md, docs/architecture.md § Layering): the rule constrains plugins that EXTEND the system, whereas this bundle's whole job is to COMPOSE the concrete spine.

The leaf no longer carries the cluster, so it has no logger entry to copy wrong by default — the common stdout-purity mistake loses its foothold. (A leaf can still *add* a sibling logger entry — a package cannot forbid what a leaf author writes — so the rule "never add a stdout logger to an ACP leaf" stays documented at the leaf; what changed is that the default leaf has nothing to get wrong.)

A block constructed today would silently vanish from the wire — the vocabulary advertised a capability no path honors, the silent-data-loss shape the defensive patterns warn against. The only constructors were tests pinning the skip/estimate branches. Remove ImageBlock and its ContentBlockMap entry (its cache?: CacheHint field leaves with it; CacheHint itself and the other two cache? fields are out of scope). compact-basic loses its explicit image estimate and placeholder arms (the merge-extensible default arms absorb the case); the deepseek serializer, pi-ai converter, and ACP codec already handled image in their default arms, so only their image-naming comments change. The codec's inbound rejection of ACP-protocol image prompt content stays — that guards wire content a client can send regardless of our vocabulary. Tests that constructed harness image blocks to pin the removed branches are dropped (the 85-token estimate pin) or retargeted onto plugin-added block types / other non-text blocks, which the surviving default arms own. Docs, the type-equiv pastes, and the content-block vocabulary RFC's block list and multimodal-home consequence are updated in the same change; the RFC moves to implemented/ and the index is regenerated. A real multimodal feature reintroduces image via declaration merging together with the adapter mapping, ACP advertisement, and compaction pricing that honor it. --- docs/architecture.md | 2 +- docs/core-data-structures/core.md | 3 +- docs/core-data-structures/llm-streaming.md | 1 - docs/rfc/README.md | 2 +- .../2026-06-11-content-block-vocabulary.md | 4 +- .../2026-07-04-drop-image-content-block.md | 27 ++++++++++++ .../2026-07-04-drop-image-content-block.md | 27 ------------ ...-prune-producerless-vocabulary-variants.md | 2 +- packages/bash/tool-bash/tests/tools.spec.ts | 2 +- packages/compact/compact-basic/README.md | 4 +- packages/compact/compact-basic/src/index.ts | 17 ++------ .../compact-basic/tests/compact-basic.spec.ts | 42 +++++++++---------- packages/llm/llm-deepseek/README.md | 1 - packages/llm/llm-deepseek/src/serialize.ts | 1 - .../llm/llm-deepseek/tests/serialize.spec.ts | 14 +++++-- packages/llm/llm-pi-ai/README.md | 2 +- packages/llm/llm-pi-ai/src/convert.ts | 2 +- packages/llm/llm-pi-ai/tests/convert.spec.ts | 6 +-- packages/llm/llm/README.md | 2 +- packages/llm/llm/src/types.ts | 16 ++++--- packages/llm/llm/tests/assembler.spec.ts | 12 +++--- packages/llm/llm/tests/properties.spec.ts | 2 +- packages/ui/acp/src/codec.ts | 6 +-- packages/ui/acp/tests/codec.spec.ts | 5 ++- packages/ui/acp/tests/stream-update.spec.ts | 2 +- 25 files changed, 97 insertions(+), 107 deletions(-) create mode 100644 docs/rfc/implemented/simplification/2026-07-04-drop-image-content-block.md delete mode 100644 docs/rfc/proposed/simplification/2026-07-04-drop-image-content-block.md diff --git a/docs/architecture.md b/docs/architecture.md index 0266f1a2e9..84c113c13b 100644 --- a/docs/architecture.md +++ b/docs/architecture.md @@ -93,7 +93,7 @@ The web capability uses the same three-package split but folds two capabilities ## The vocabulary (dsh-llm) -Messages are arrays of typed **content blocks** (`text`, `reasoning`, `tool-call`, `tool-result`, `image`); the union is derived from the merge-extensible `ContentBlockMap`, so plugins can add block types via declaration merging.

Retention is **turn-agnostic** — turn boundaries play no role, so a single runaway turn that alone exceeds the window compacts its OWN early closed steps rather than being retained verbatim (the failure mode that motivated dropping turn-protection: a tool-heavy turn must stay compactable or the harness dies exactly when compaction is needed). The only structural guard is **tool-pairing balance**: the compacted region's edges are balanced cuts on the surface (no unanswered tool-call crosses either edge), so it never splits a step's `assistant/message` tool-calls from their `tool/result`s. When the only compactable content left is an un-splittable open tail step, it declines (returns `null`) and retries once an older step closes. **Single-unit overflow is out of scope, by design**: if one retained unit (a single closed step, or a large pasted `user/message`) ALONE exceeds the budget, compaction cannot help and the call may go out over-budget — bounding an individual unit's size is a separate concern. `compactRegion()` enforces tool-pairing balance strictly, throwing on a boundary that would split a step. `dsh-session` exports `isToolPairingBalanced` for the check. - **Dynamic convergence** — no static summary-length config pretends to bound what the model will write. If framing/estimator/system overhead leaves the compacted surface above threshold, `compactIfNeeded()` re-compacts the head checkpoint up to `compactionRetries` extra times; if it still cannot get below threshold, it throws. A summary whose estimated stored size is not smaller than the shadowed content fails closed before it mutates the surface. -- **Summarization** — `summarize()`: a `GenerateOptions` request assembled via `BlockAssembler` with a fixed system prompt that asks for a structured checkpoint (Primary Request and Intent · Key Technical Concepts · Files and Code · Errors and Fixes · Pending Tasks · Current Work · Next Step · Critical Context), every section mandatory, exact paths/commands/identifiers preserved. The request runs through the `agent/request` waterfall before `ctx.llm.stream()`, so router agents that choose the concrete model there also route compaction summaries. `maxTokens` is the provider-side generation cap; only text blocks from the model's reply are kept before the checkpoint is stored (reasoning is dropped so private chain-of-thought never leaks into the durable summary, and a stray `tool-call` is dropped so the synthesized `user/message` summary cannot land an orphaned call with no matching `tool-result`). The compacted region is flattened to a plain-text transcript first: text and reasoning contribute their text, and every non-text block (image, tool-call, tool-result, plugin-added types) contributes a type-tagged placeholder (`[image]`, `[tool-call: name(args)]`, …) so the summarizer is told what existed rather than silently dropping it. +- **Summarization** — `summarize()`: a `GenerateOptions` request assembled via `BlockAssembler` with a fixed system prompt that asks for a structured checkpoint (Primary Request and Intent · Key Technical Concepts · Files and Code · Errors and Fixes · Pending Tasks · Current Work · Next Step · Critical Context), every section mandatory, exact paths/commands/identifiers preserved.

Because region compaction can be invoked manually, a surface may hold several checkpoints, so the framing does not claim everything after it is recent or verbatim. The tags make a prior checkpoint detectable in the transcript on the next compaction cycle: the summarization prompt then instructs the model to merge it in place (preserve still-true facts, drop stale ones) rather than re-summarize it verbatim — a cheap incremental merge that needs no extra log/event machinery. The unframed summary stays on the `compact/summary` provenance event. - **Surface mutation** — `compactRegion()` appends the `compact/start` → `compact/summary` → `compact/end` log records and the single `user/message` replace node carrying the framed summary (see the interface README). - **Auto-compaction** — an `agent/pre-step` listener delegates to `compactIfNeeded()` before every step (not just a turn's first — a tool-heavy turn grows the surface mid-turn, so a runaway turn still compacts, and per-step firing is the only moment to rescue it before overflow). `agent/pre-step` is a serial (awaited, in-order) surface-mutation checkpoint that fires after `turn/start` and BEFORE the step opens (`step/start`) and its request history is derived, so compaction mutates the surface — with its log-only `compact/*` records landing cleanly outside any step — and the loop derives once from the result: no double-derive, and the listener cannot see (or need to rewrite) an already-assembled `messages` array. The listener owns no threshold logic of its own (the single token-pressure check lives in `compactIfNeeded()`); because Cordis `serial` bails early on non-void return values, the listener returns `void` and does not use the dispatcher's bail channel as a veto surface. diff --git a/packages/compact/compact-basic/src/index.ts b/packages/compact/compact-basic/src/index.ts index f53dace461..2986c3d15d 100644 --- a/packages/compact/compact-basic/src/index.ts +++ b/packages/compact/compact-basic/src/index.ts @@ -44,9 +44,6 @@ export { resolveConfig } from './types.ts' /** Per-block structural overhead for JSON framing / type tag. */ const BLOCK_OVERHEAD = 4 -/** Heuristic token count for an image block (~85 tokens for low-res URL). */ -const IMAGE_TOKEN_COST = 85 - /** Role-field framing overhead added per message in {@link BasicCompactService.estimateTokens}. */ const ROLE_OVERHEAD = 4 @@ -230,9 +227,6 @@ export class BasicCompactService extends CompactService { case 'tool-result': tokens += this.estimateContentTokens(block.content) + BLOCK_OVERHEAD break - case 'image': - tokens += IMAGE_TOKEN_COST - break default: // Unknown block types (merge-extensible ContentBlockMap): // estimate conservatively via JSON stringify. @@ -706,10 +700,10 @@ export class BasicCompactService extends CompactService { /** * Render content blocks to a single plain-text string for the summarization * prompt.

For a behavior change to the agent's real flows, a no-key/mock test alone is usually insufficient: a with-key e2e (especially a smoke test that boots the real example and checks the world) is cheap here and catches "green units, broken product" — encourage it rather than treating real-API tests as expensive (see AGENTS.md § Secrets / .env). - **Plugin export shape + real-loader coverage.** A new/changed `cordis.yml`-loaded plugin: is it a function/namespace plugin (`name`/`inject`/`Config`/`apply` named exports) with NO `export default`? A stray default export makes the Loader's `unwrapExports` drop `inject` and the plugin crashes at load with `cannot get property … without inject` — invisible to hand-built `ctx.plugin({...})` tests and to line coverage. Confirm there's a test driving it through the REAL loader path (the no-key subprocess e2e for ACP is the model). And any opportunistic read of a service NOT in `static inject` should use `ctx.get(name)`, not `ctx.<name>` (the property proxy throws through a foreign shadow).

Check it's split per the capability-seams RFC (interface / impl / consumer), and that the consumer injects the interface key, never an implementation type. +- **Hardcoded tunables that should be plugin config.** A literal timeout, grace period, output/truncation cap, result-count limit, retry count, buffer size, model name, API base URL, user agent, or filesystem path introduced inside a plugin belongs on the plugin's schemastery `Config` with the shipped value as its default (AGENTS.md § Conventions "No hardcoded tunables in plugins"). A named `DEFAULT_*` constant or a test-only injection seam is not configurability — the question to ask is whether a `cordis.yml` deployment can change the value without a code edit. Protocol/wire constants, semantic constants, values pinned by an external spec, and security invariants are exempt; a new `Config` field also needs its README row and range validation. No gate detects a hardcoded tunable — this check is entirely on the reviewer. - **Test quality — sufficiency, not just coverage.** 100% per-file coverage and a green suite are necessary, not sufficient: they prove the lines *ran*, not that the feature *works the way it ships*. Judge whether the tests are sufficient on two axes. (1) **Would they fail if the behavior regressed?** A test that passes but asserts the wrong thing — or restates the implementation instead of the contract (events fired, disposal reached, the world changed) — is worse than none. (2) **Do they exercise the REAL thing, the way it's actually used?** Prefer the genuine collaborator over a fake, drive the change through its real entry path (the cordis Loader, the ACP bridge, a booted subprocess — not a hand-built `ctx.plugin({...})` that bypasses `unwrapExports`), and verify the WORLD (re-read the file/log/registry externally), not the agent's self-report. A test that fakes the inputs just enough to cover every line will agree with whatever the author assumed; the real thing won't. When a test sets up a *clean/happy* path to reach a line, ask whether the line's PURPOSE is exercised — e.g. a durability/teardown path "tested" by a fully-completed turn never proves the mid-flight teardown it exists for; a torn-tail recovery branch covered by a well-formed log never proves recovery. Flag tests that hit the line but not the scenario. See AGENTS.md § Defensive patterns "Line coverage is not behavior coverage" and "Prefer the REAL implementation over a mock/stand-in in tests". - **Snapshot coverage for transcript/UX changes.** If the PR changes the editor-facing transcript or end-to-end agent UX — the ACP bridge's event→update translation, the agent loop's observable output, tool presentation, or anything an editor renders — it must add or update a snapshot scenario (`examples/*/tests/**/*.snapshot.ts`, goldens under `examples/acp-agent/tests/snapshots/`) or note explicitly why none applies (AGENTS.md § Conventions). Review the golden diff itself: a changed `stdout.golden.txt` / `session.golden.txt` is a behavior change in disguise — confirm it's intended, not an accidental regression someone re-recorded away. A pure internal refactor with no observable-output change is exempt, but the PR should say so.

Changing `agent-loop` requires updating that doc. - **Capability seams are three packages**: when adding a swappable capability (an execution backend, a provider integration, …), split it into *interface* (abstract service + vocabulary types, e.g. `bash/`), *implementation* (a concrete subclass, e.g. `bash-local/`), and *consumer* (what the model/plugins see, e.g. `tool-bash/`). Implementations and consumers then evolve independently — a sandboxed executor replaces `bash-local` without touching tool schemas. The LLM seam follows the same shape (`llm/` is interface + consumer surface; adapters are implementations). See docs/architecture.md § "Capability seams" for when NOT to split. - **Explicit > implicit at package seams**: interface/vocabulary types spell out every field a consumer must supply — no optional field that the implementation silently fills with a hidden `?? default`. Put defaulting in the owning implementation as an explicit step (a `resolve(request): Spec` method that turns the optional-field request into the required-field spec), not smuggled inside `run()`/`start()`. Example: `dsh-bash` splits `BashExecRequest` (optional `workdir`/`timeoutMs`, model-facing) from `BashExecSpec` (required, what `run`/`start` act on); the tool layer calls `ctx.bash.resolve()` between them. The reader of a `BashExecSpec` never has to wonder where the working directory came from. +- **No hardcoded tunables in plugins — a deployment knob belongs on `Config`**: a number or string that two reasonable deployments could want set differently — a timeout, grace period, output/truncation cap, result-count limit, retry count, buffer size, model name, API base URL, user agent, filesystem path — is plugin configuration, not a bare literal or module constant. Expose it as a field on the plugin's schemastery `Config` with the shipped value as its `.default(…)`, document it in the package README, and validate the range where garbage would misbehave silently (see `assertPositiveFinite` in `dsh-bash-local`/`dsh-web-fetch-local`). A named `DEFAULT_*` constant does not make a value configurable, and neither does a test-only injection seam (`internals`) — the test is whether a `cordis.yml` deployment can change the value without a code edit. The rule is scoped to genuine tunables: protocol/wire constants (format versions, method names, event tags), semantic constants (exit codes, signal names, HTTP statuses), values pinned by an external spec, and security invariants (the credential-scrub env pattern) stay hardcoded — making those configurable invites misconfiguration, not flexibility. When unsure, ask who would ever set it: a deployer tuning the product (config) or only a maintainer changing the design (constant). The exemplar is `dsh-web-fetch-local`, whose every cap is a defaulted `Config` field. - **Opaque cross-boundary ids are branded, never bare `string`**: an identity that crosses a package seam and that a consumer must store-and-return but never parse (a backend-defined version token, a target key, a task/session/call id) is a `Branded<B>` from `@deepseek-ai/dsh-brand` with a same-named cast factory in the owning package — a zero-cost compile-time guard so semantically-distinct strings stop being interchangeable. Not every string needs it: author-readable names (`ToolName`) and closed code unions (`ErrorCode`) don't. See [Branded IDs everywhere they belong](docs/rfc/implemented/architecture/2026-06-20-branded-ids.md). - **An empty `catch` must name what it swallows and why nothing else can hit it**: a bare `catch {}` hides bugs. When you deliberately ignore a throw, the comment must (a) name the single expected failure, (b) say why ignoring it is correct — usually because the useful state was already captured *before* the `try` — and (c) make clear nothing else of consequence can reach the catch (ideally the `try` wraps a single statement). Example: the error-body `response.json()` parse in `dsh-llm-deepseek`'s adapter sets `code` + HTTP `status` from the status line before the `try`, so a malformed provider body can only cost a richer message, never the real error. - **Symmetry is usually more correct**: when two related values play parallel roles (a test fixture and its expected output, a request shape and its response shape, a buggy input and the test that checks the fix), give them parallel form — both named consts, or both inline, not one each way. Asymmetry is a smell that usually points at a missed extraction.

Defaults are the previously hardcoded values throughout, so no deployment or golden changes. - tool-fs (had NO Config): readLimit, readMaxLineLength, readMaxBytes, readStreamMinSize. The caps thread through ReadToolCaps/ReadWindow — read-render already documented that the consumer applies the caps, so they become explicit per-request fields. - tool-web: searchMaxResults (WEB_SEARCH_MAX_RESULTS stays as the schemastery default). Also fixes the stale GREP_LIMIT references in search.ts and the web-capability-seam RFC (no such constant exists). - bash-local: graceMs (SIGTERM->SIGKILL escalation grace). The RunInternals.graceMs test seam is gone: graceMs is now a required SpawnSpec field filled from config, so tests exercise the real config path and the defaults live in exactly one place. - subagent-acp: disposeEofGraceMs / disposeGraceMs. The AcpRunSpec fields become required for the same one-defaulting-layer reason. - session-persistence-sqlite: journalMode ('wal' default; the rollback-journal modes serve filesystems where WAL's shared-memory files do not work, e.g. network mounts). - hooks-claude + hooks-codex: stderrSummaryMaxChars for the persisted hook/result stderr summary. The duplicated summarize() helpers merge into hook-protocol's summarizeStderr(stderr, maxChars), beside the HookResultRecord field it feeds, with the bound parameterized the same way runHook's defaultTimeoutMs already is. - compact-basic: charsPerToken for the token estimator (default 4, the English-text heuristic; CJK-heavy deployments need ~1-2 or compaction fires far too late). Also corrects the BasicCompactService class doc, which claimed defaults the required-field config never had. - fs-local: deletes the dead STREAM_MIN_SIZE constant and the dead FsIoInternals.streamMinSize seam — the read-routing bound lives in the consumer (tool-fs), where it is now config. This is item 1 of the proposed prune-write-only-fs-surface RFC, annotated accordingly. Every new field gets range validation (following the existing assertPositiveFinite pattern), a README row, and tests covering the configured behavior, the schema default, and load-time rejection. --- docs/core-data-structures/web.md | 2 +- .../2026-06-24-web-capability-seam.md | 2 +- .../2026-07-04-prune-write-only-fs-surface.md | 2 +- packages/bash/bash-local/README.md | 3 +- packages/bash/bash-local/src/index.ts | 12 +++- packages/bash/bash-local/src/run.ts | 11 ++- .../bash/bash-local/tests/executor.spec.ts | 27 +++++--- packages/bash/bash-local/tests/run.spec.ts | 3 +- packages/bash/tool-bash/tests/tools.spec.ts | 16 ++--- packages/compact/compact-basic/README.md | 1 + packages/compact/compact-basic/src/index.ts | 31 +++++---- packages/compact/compact-basic/src/types.ts | 31 +++++++-- .../compact-basic/tests/compact-basic.spec.ts | 17 +++++ packages/fs/fs-local/src/fsio.ts | 10 +-- packages/fs/fs-local/src/index.ts | 1 - packages/fs/tool-fs/README.md | 13 +++- packages/fs/tool-fs/package.json | 3 +- packages/fs/tool-fs/src/index.ts | 49 +++++++++++++- packages/fs/tool-fs/src/read-render.ts | 27 ++++---- packages/fs/tool-fs/src/read.ts | 44 ++++++++---- packages/fs/tool-fs/tests/read-render.spec.ts | 24 +++++-- packages/fs/tool-fs/tests/tools.spec.ts | 67 +++++++++++++++++++ packages/fs/tool-fs/tsconfig.json | 1 + packages/hooks/hook-protocol/src/events.ts | 12 ++++ packages/hooks/hook-protocol/src/index.ts | 2 +- .../hooks/hook-protocol/tests/events.spec.ts | 19 +++++- packages/hooks/hooks-claude/README.md | 1 + packages/hooks/hooks-claude/src/index.ts | 14 ++-- .../hooks/hooks-claude/tests/coverage.spec.ts | 17 ++++- packages/hooks/hooks-codex/README.md | 1 + packages/hooks/hooks-codex/src/index.ts | 13 ++-- .../hooks/hooks-codex/tests/coverage.spec.ts | 17 ++++- .../session-persistence-sqlite/README.md | 3 +- .../session-persistence-sqlite/src/index.ts | 21 ++++-- .../session-persistence-sqlite/src/schema.ts | 21 ++++-- .../tests/sqlite.spec.ts | 50 ++++++++++---- packages/subagent/subagent-acp/README.md | 2 + packages/subagent/subagent-acp/src/index.ts | 32 ++++++++- packages/subagent/subagent-acp/src/run.ts | 37 +++++----- .../subagent-acp/tests/subagent-acp.spec.ts | 18 ++++- packages/web/tool-web/README.md | 1 + packages/web/tool-web/src/index.ts | 22 +++++- packages/web/tool-web/src/search.ts | 14 ++-- packages/web/tool-web/tests/tool-web.spec.ts | 46 +++++++++++++ pnpm-lock.yaml | 3 + 45 files changed, 592 insertions(+), 171 deletions(-) diff --git a/docs/core-data-structures/web.md b/docs/core-data-structures/web.md index 1adde3bd75..42797a8d99 100644 --- a/docs/core-data-structures/web.md +++ b/docs/core-data-structures/web.md @@ -10,7 +10,7 @@ Search and fetch share no request schema and no business logic, but they are del ## Search request and result -The model-facing tool argument is just a `query`; `maxResults` is a consumer-owned bound (`dsh-tool-web`'s `WEB_SEARCH_MAX_RESULTS`, default `8`) passed through the seam and enforced on the way back — if a provider over-returns, the seam truncates `sources[]` and sets `truncated`. +The model-facing tool argument is just a `query`; `maxResults` is a consumer-owned bound (`dsh-tool-web`'s `searchMaxResults` config, default `8`) passed through the seam and enforced on the way back — if a provider over-returns, the seam truncates `sources[]` and sets `truncated`. ```ts type-equiv interface WebSearchRequest { diff --git a/docs/rfc/implemented/architecture/2026-06-24-web-capability-seam.md b/docs/rfc/implemented/architecture/2026-06-24-web-capability-seam.md index 55ada9d576..833cbeebb5 100644 --- a/docs/rfc/implemented/architecture/2026-06-24-web-capability-seam.md +++ b/docs/rfc/implemented/architecture/2026-06-24-web-capability-seam.md @@ -175,7 +175,7 @@ The first `web_search` model-facing tool should be small.

All four surveyed tools spawn per call. `XXX(stateful-shell)` in `src/run.ts` records the two proven stateful designs (Claude Code's cwd-only persistence; Codex's PTY exec sessions) for when real workflows demand them. -- **Process-group kills with escalation** — children are spawned `detached` (own process group); kills send SIGTERM to the group, then SIGKILL after a 3s grace (OpenCode's escalation; pipelines and subshells die with the parent). ESRCH is tolerated; daemons that re-parent away from the group can still survive — same caveat as the surveyed tools. +- **Process-group kills with escalation** — children are spawned `detached` (own process group); kills send SIGTERM to the group, then SIGKILL after the `graceMs` grace (default 3s — OpenCode's escalation; pipelines and subshells die with the parent). ESRCH is tolerated; daemons that re-parent away from the group can still survive — same caveat as the surveyed tools. - **Tail-keep truncation + spill files** — output beyond `maxOutputBytes` keeps the in-memory TAIL (errors/results cluster at the end — pi/OpenCode rationale) while the FULL stream is appended to a temp file whose path is reported when available. If the final spill close reports a delayed writeback failure, the executor still returns the tail but withholds the path rather than advertising a possibly incomplete file. - **Model-friendly env + credential scrub** — `process.env` minus credential-shaped vars (`*KEY*`/`*SECRET*`/`*TOKEN*`), then `NO_COLOR=1 TERM=dumb PAGER=cat GIT_PAGER=cat` (Codex's hardcoded set) so pagers and ANSI color don't garble results. This scrub is the security control that keeps the harness's *ambient* credentials out of a spawned command. A spec's `env` is merged LAST (after the scrub), so a caller's explicit entry — a value it already holds — wins even on a credential-shaped name. The spec's `stdin`, when supplied, is written to the child and closed; with none supplied, fd 0 is `/dev/null` — the exact pre-seam default, so a command that probes stdin's file type is unaffected. Both `env`/`stdin` are set by in-process plugins (the hooks bridges); the model-facing tool doesn't expose them. See [the bash-stdin-env RFC](../../../docs/rfc/implemented/architecture/2026-06-30-bash-stdin-env-trusted-plugin-surface.md). - **Background tasks** — `start()` returns immediately, no timeout applies (Claude Code detaches timeouts when backgrounding), `readOutput()` is incremental with whole-stream byte offsets, and disposal kills everything. The spec's opaque `owner` token is stored on the tracked task and returned by `ownerOf(id)` — the executor never interprets it (the consumer's access policy does), and because it lives with the task here it survives a `tool-bash` HMR reload. diff --git a/packages/bash/bash-local/src/index.ts b/packages/bash/bash-local/src/index.ts index af4c47e71e..6df7b3da7b 100644 --- a/packages/bash/bash-local/src/index.ts +++ b/packages/bash/bash-local/src/index.ts @@ -17,7 +17,7 @@ import { Context } from 'cordis' import z from 'schemastery' import { BashExecutor, BashTaskId } from '@deepseek-ai/dsh-bash' import type { BashExecRequest, BashExecSpec, BashRunResult, BashTask, BashTaskRead, OwnerToken } from '@deepseek-ai/dsh-bash' -import { runBash } from './run.ts' +import { DEFAULT_GRACE_MS, runBash } from './run.ts' import type { RunInternals, RunningBash } from './run.ts' export { DEFAULT_GRACE_MS, ENV_OVERRIDES, killGroup, OutputCollector, runBash } from './run.ts' @@ -33,6 +33,8 @@ export interface Config { maxTimeoutMs?: number /** Per-stream in-memory output cap; overflow spills to a temp file. */ maxOutputBytes?: number + /** Grace period between the SIGTERM and the SIGKILL escalation on a kill. */ + graceMs?: number } /** The shape after schemastery applied the defaults (cwd has none). */ @@ -57,7 +59,7 @@ interface TrackedTask extends BashTask { * Local-subprocess bash executor.

Both bridges now assert a positive integer at the TOP of apply() (before the config-file parse's early return, so a bad value fails the load loudly), with rejection tests. - tool-fs: the read caps count lines/chars/bytes, so positive-FINITE was too loose (a fractional readLimit would flow into windowing arithmetic and the schema description). All four now require a positive integer, matching tool-web's cap. - Doc drift the gates cannot catch: tool-web's README tools table still named WEB_SEARCH_MAX_RESULTS as the mechanism; compact-basic's README/module doc and the compaction-capability-seam RFC still described estimation as fixed char/4 rather than the charsPerToken default. - subagent-acp: the dispose graces were tested only at the startAcpRun level, so a regression that stopped threading plugin config into AcpRunSpec would have survived.

Retention is **turn-agnostic** — turn boundaries play no role, so a single runaway turn that alone exceeds the window compacts its OWN early closed steps rather than being retained verbatim (the failure mode that motivated dropping turn-protection: a tool-heavy turn must stay compactable or the harness dies exactly when compaction is needed). The only structural guard is **tool-pairing balance**: the compacted region's edges are balanced cuts on the surface (no unanswered tool-call crosses either edge), so it never splits a step's `assistant/message` tool-calls from their `tool/result`s. When the only compactable content left is an un-splittable open tail step, it declines (returns `null`) and retries once an older step closes. **Single-unit overflow is out of scope, by design**: if one retained unit (a single closed step, or a large pasted `user/message`) ALONE exceeds the budget, compaction cannot help and the call may go out over-budget — bounding an individual unit's size is a separate concern. `compactRegion()` enforces tool-pairing balance strictly, throwing on a boundary that would split a step. `dsh-session` exports `isToolPairingBalanced` for the check. - **Dynamic convergence** — no static summary-length config pretends to bound what the model will write. If framing/estimator/system overhead leaves the compacted surface above threshold, `compactIfNeeded()` re-compacts the head checkpoint up to `compactionRetries` extra times; if it still cannot get below threshold, it throws. A summary whose estimated stored size is not smaller than the shadowed content fails closed before it mutates the surface. - **Summarization** — `summarize()`: a `GenerateOptions` request assembled via `BlockAssembler` with a fixed system prompt that asks for a structured checkpoint (Primary Request and Intent · Key Technical Concepts · Files and Code · Errors and Fixes · Pending Tasks · Current Work · Next Step · Critical Context), every section mandatory, exact paths/commands/identifiers preserved. The request runs through the `agent/request` waterfall before `ctx.llm.stream()`, so router agents that choose the concrete model there also route compaction summaries. `maxTokens` is the provider-side generation cap; only text blocks from the model's reply are kept before the checkpoint is stored (reasoning is dropped so private chain-of-thought never leaks into the durable summary, and a stray `tool-call` is dropped so the synthesized `user/message` summary cannot land an orphaned call with no matching `tool-result`). The compacted region is flattened to a plain-text transcript first: text and reasoning contribute their text, and every non-text block (image, tool-call, tool-result, plugin-added types) contributes a type-tagged placeholder (`[image]`, `[tool-call: name(args)]`, …) so the summarizer is told what existed rather than silently dropping it. diff --git a/packages/compact/compact-basic/src/index.ts b/packages/compact/compact-basic/src/index.ts index 26c593a47f..a1a83cd407 100644 --- a/packages/compact/compact-basic/src/index.ts +++ b/packages/compact/compact-basic/src/index.ts @@ -2,7 +2,8 @@ * `BasicCompactService`: the first implementation of the * `@deepseek-ai/dsh-compact` seam.

That is useful for provider-side support, abuse investigation, compatibility debugging, traffic analytics, and public app attribution where a provider exposes it. Before this RFC the harness only partially did this: the hand-rolled DeepSeek adapter sent a hand-copied `User-Agent` constant (`packages/llm/llm-deepseek/src/adapter.ts`), while the pi-ai-backed twin sent no harness-owned headers at all (`packages/llm/llm-pi-ai/src/adapter.ts`). New adapters could therefore omit attribution silently, and a library-backed adapter could drift from the hand-rolled adapter even though [the twin-adapter RFC](2026-06-13-twin-llm-adapters.md) exists to keep the provider seam honest across both implementations. + +The immediate prompt came from OpenRouter's [App Attribution](https://openrouter.ai/docs/app-attribution) docs. OpenRouter creates app pages and rankings from `HTTP-Referer` plus display/category headers. That is valuable, but it is not the HTTP standard for application identity. The risk is adopting OpenRouter's exact header set as if it were universal, then leaking provider-specific headers to direct DeepSeek requests, future OpenAI/Anthropic/Vertex adapters, test servers, or proxies that log unknown fields indefinitely. + +## Investigation + +- **OpenRouter's mechanism is provider-specific.** Their current docs say app attribution is tracked through `HTTP-Referer` (required), `X-OpenRouter-Title`, and `X-OpenRouter-Categories`; `X-Title` is only accepted for backward compatibility. Their API reference calls the headers optional and says they make the app discoverable on OpenRouter. This is a concrete OpenRouter contract, not an IETF or OpenAI-compatible API standard. +- **In agent tooling, `HTTP-Referer` is an OpenRouter-aware convention, not a general agent convention.** It is common enough that OpenRouter SDKs and OpenRouter examples expose it directly, and frameworks that target OpenRouter usually need a way to pass it through. But agent protocols such as ACP negotiate names, versions, and capabilities in their own initialize messages, while model-provider requests still need HTTP-level identity. "Accepted in the agent world" therefore means "recognized by OpenRouter integrations," not "portable across agent runtimes or providers." +- **Observed coding agents use product/version `User-Agent` strings, sometimes with environment context.** A non-exhaustive public-code survey found OpenAI Codex building `{originator}/{version} ({os} {os_version}; {arch}) ...` and carrying an `originator` header; Google Gemini CLI sending `GeminiCLI[-clientName]/{version}/{model} ({platform}; {arch}; {surface})` or a Cloud Code VS Code variant; Cline's Codex backend client sending `cline/{version} ({platform} {release}; {arch}) node/{nodeVersion}` plus `originator: cline`; SWE-agent setting `swe-agent/{version}` unless the user already supplied a header; Continue setting `Continue/{version}` for its ClawRouter provider plus `X-Continue-Provider`. Aider also appends `Aider/{version} +{website}` to browser-like user agents for web scraping, but that is not a model-provider request path. The pattern is not one exact format; it is product identity in `User-Agent`, with provider-specific side headers only where a provider/backend asks for them. +- **The standards-track general client identity header is `User-Agent`.** RFC 9110 section 10.1.5 defines `User-Agent` as the user-agent software identity, says it is used for interoperability reports and analytics, and says a user agent SHOULD send it on each request unless configured not to. This is the only standard header that directly matches "what product is making this HTTP request." +- **`Referer` is standard, but OpenRouter's `HTTP-Referer` is not the standard field.** RFC 9110 section 10.1.3 defines `Referer` as the URI from which the target URI was obtained and spends significant text on privacy restrictions. OpenRouter instead asks for `HTTP-Referer`, using it as an app URL identifier. That name and meaning are OpenRouter-specific even though it resembles the CGI environment variable form of the standard `Referer` header. +- **`From` is standard but not suitable as a mandatory default.** RFC 9110 section 10.1.2 defines `From` as an email address for the human responsible for a user agent. Robotic agents SHOULD send it so servers can contact an operator, but non-robotic agents should not send it without explicit user configuration because of privacy and security policy concerns. The harness can support an operator contact later, but must not invent one or require it globally. +- **Request-body `user` or `metadata` fields are not app attribution.** Some model APIs expose a stable end-user identifier, request metadata, labels, or project/account headers. Those are useful for abuse monitoring, internal billing, dashboards, or trace correlation, but they either identify the end user rather than the product, are provider-specific body schema, or are not guaranteed to be forwarded through OpenAI-compatible gateways.

The proposal's alternative arm — recognizing `https://openrouter.ai/api/v1` by exact match — was not taken: it trades a magic constant for covering only one spelling of the endpoint (proxied/regional URLs still need the option), and a user pointing `baseURL` at OpenRouter without the flag still sends the standard `User-Agent` baseline. + +`AttributionTarget` is a closed union (`switch` + `assertNever`), deliberately **not** merge-extensible: an attribution mapping is a documented cross-provider contract owned by `dsh-llm`, not a plugin extension point, so a future provider mapping is a compile-visible change to the owning module. + +## Acceptance criteria (all landed) + +- `dsh-llm` documents the mandatory app-attribution contract for `LlmAdapter` authors (`LlmAdapter` JSDoc, package README, and the adapter-contract section of `docs/core-data-structures/llm-streaming.md`). +- A shared helper (`attributionHeaders` / `userAgent`) constructs the app identity and the standard `User-Agent` value from package metadata, so adapters do not hand-copy version constants. +- `dsh-llm-deepseek` sends the shared headers on every request; its mock-server suite asserts the exact `User-Agent`, asserts the OpenRouter set is absent by default, and asserts the exact OpenRouter headers when `attributionTarget: 'openrouter'` is configured. +- `dsh-llm-pi-ai` sends the same headers through pi-ai's `StreamOptions.headers` hook, with the same three wire-level assertions — the twin contract includes attribution. +- No app-attribution field carries secrets, local paths, session ids, prompt text, model output, user email, or per-user stable identifiers. +- The adapter READMEs state the attribution policy and the OpenRouter-specific mapping. + +## Alternatives considered + +**OpenRouter headers everywhere.** Rejected.

It is the correct baseline and the only standard mechanism, but it cannot create OpenRouter app pages or marketplace rankings because OpenRouter requires `HTTP-Referer` for that product feature. Deferring the OpenRouter mapping until an in-repo OpenRouter deployment existed was also considered and rejected: the DeepSeek adapters already accept any OpenAI-compatible `baseURL`, so OpenRouter is reachable today via config alone, and the mapping is small enough that shipping it with wire tests costs less than re-opening the contract later. + +**Only provider account/project identity.** Rejected.

Mitigation: send only static public product data and let forks/white-label deployments pass their own `AppIdentity`. + +**The app URL points at a repository that does not exist yet.** `deepseek-ai/deepseek-harness-sdk` is the planned public home; until it is created the URL is a dangling promise. The `FIXME` marker on the constant blocks a release from shipping with it unresolved (see `docs/development.md` marker semantics). + +**Header support differs by client library.** The hand-rolled adapter sets headers directly; the pi-ai-backed adapter depends on pi-ai continuing to honor `StreamOptions.headers` (merged last over provider defaults).

That is useful for provider-side support, abuse investigation, compatibility debugging, traffic analytics, and public app attribution where a provider exposes it. The harness only partially does this today: the hand-rolled DeepSeek adapter sends `User-Agent: deepseek-harness/0.0.1` (`packages/llm/llm-deepseek/src/adapter.ts`), while the pi-ai-backed twin has no harness-owned header path visible in this repo (`packages/llm/llm-pi-ai/src/adapter.ts`). New adapters can therefore omit attribution silently, and a library-backed adapter can drift from the hand-rolled adapter even though [the twin-adapter RFC](../../implemented/architecture/2026-06-13-twin-llm-adapters.md) exists to keep the provider seam honest across both implementations. - -The immediate prompt came from OpenRouter's [App Attribution](https://openrouter.ai/docs/app-attribution) docs. OpenRouter creates app pages and rankings from `HTTP-Referer` plus display/category headers. That is valuable, but it is not the HTTP standard for application identity. The risk is adopting OpenRouter's exact header set as if it were universal, then leaking provider-specific headers to direct DeepSeek requests, future OpenAI/Anthropic/Vertex adapters, test servers, or proxies that log unknown fields indefinitely. - -## Investigation - -- **OpenRouter's mechanism is provider-specific.** Their current docs say app attribution is tracked through `HTTP-Referer` (required), `X-OpenRouter-Title`, and `X-OpenRouter-Categories`; `X-Title` is only accepted for backward compatibility. Their API reference calls the headers optional and says they make the app discoverable on OpenRouter. This is a concrete OpenRouter contract, not an IETF or OpenAI-compatible API standard. -- **In agent tooling, `HTTP-Referer` is an OpenRouter-aware convention, not a general agent convention.** It is common enough that OpenRouter SDKs and OpenRouter examples expose it directly, and frameworks that target OpenRouter usually need a way to pass it through. But agent protocols such as ACP negotiate names, versions, and capabilities in their own initialize messages, while model-provider requests still need HTTP-level identity. "Accepted in the agent world" therefore means "recognized by OpenRouter integrations," not "portable across agent runtimes or providers." -- **Observed coding agents use product/version `User-Agent` strings, sometimes with environment context.** A non-exhaustive public-code survey found OpenAI Codex building `{originator}/{version} ({os} {os_version}; {arch}) ...` and carrying an `originator` header; Google Gemini CLI sending `GeminiCLI[-clientName]/{version}/{model} ({platform}; {arch}; {surface})` or a Cloud Code VS Code variant; Cline's Codex backend client sending `cline/{version} ({platform} {release}; {arch}) node/{nodeVersion}` plus `originator: cline`; SWE-agent setting `swe-agent/{version}` unless the user already supplied a header; Continue setting `Continue/{version}` for its ClawRouter provider plus `X-Continue-Provider`. Aider also appends `Aider/{version} +{website}` to browser-like user agents for web scraping, but that is not a model-provider request path. The pattern is not one exact format; it is product identity in `User-Agent`, with provider-specific side headers only where a provider/backend asks for them. -- **The standards-track general client identity header is `User-Agent`.** RFC 9110 section 10.1.5 defines `User-Agent` as the user-agent software identity, says it is used for interoperability reports and analytics, and says a user agent SHOULD send it on each request unless configured not to. This is the only standard header that directly matches "what product is making this HTTP request." -- **`Referer` is standard, but OpenRouter's `HTTP-Referer` is not the standard field.** RFC 9110 section 10.1.3 defines `Referer` as the URI from which the target URI was obtained and spends significant text on privacy restrictions. OpenRouter instead asks for `HTTP-Referer`, using it as an app URL identifier. That name and meaning are OpenRouter-specific even though it resembles the CGI environment variable form of the standard `Referer` header. -- **`From` is standard but not suitable as a mandatory default.** RFC 9110 section 10.1.2 defines `From` as an email address for the human responsible for a user agent. Robotic agents SHOULD send it so servers can contact an operator, but non-robotic agents should not send it without explicit user configuration because of privacy and security policy concerns. The harness can support an operator contact later, but must not invent one or require it globally. -- **Request-body `user` or `metadata` fields are not app attribution.** Some model APIs expose a stable end-user identifier, request metadata, labels, or project/account headers. Those are useful for abuse monitoring, internal billing, dashboards, or trace correlation, but they either identify the end user rather than the product, are provider-specific body schema, or are not guaranteed to be forwarded through OpenAI-compatible gateways. They are not a substitute for a static application identity header. -- **SDK telemetry headers identify the SDK, not the app.** Official and third-party SDKs often send library/version headers. Those help the SDK maintainer debug their client, but they do not identify "DeepSeek Code" as the application unless the application explicitly supplies a product attribution layer. - -## Proposal - -Make provider request attribution mandatory at the LLM adapter boundary, with a provider-neutral app identity and provider-specific wire mappings. The rule is: every product LLM adapter must send a static, non-secret application identity on every provider HTTP request, and every adapter must have tests proving the identity reaches the wire or, for a library-backed adapter, proving the configured library hook emits equivalent headers. - -For OpenRouter specifically, mandatory attribution means sending **both** the provider-neutral `User-Agent` and OpenRouter's required app identifier, `HTTP-Referer`. `User-Agent` identifies the client software in the standard HTTP way; `HTTP-Referer` is the OpenRouter-specific app URL key that creates the app page and ranking entry. `X-OpenRouter-Title` and `X-OpenRouter-Categories` refine that same OpenRouter app identity. - -The provider-neutral identity should be owned outside individual adapters, ideally in `dsh-llm` or a tiny support package if importing package metadata from `dsh-llm` is too awkward. It should contain only public product facts: - -- product token for `User-Agent`: `deepseek-code` or `deepseek-harness` (settle this when implementation chooses the public product name) -- version: the package/root version, not a manually duplicated constant -- app title: `DeepSeek Code` -- app URL: the public product or repository URL, not a local workspace path -- optional category list for providers that support public app marketplaces, initially `cli-agent` - -The default is mandatory and non-empty. Deployments may override the title/URL/category values for white-label products or forks, but omission must fall back to the harness default rather than suppress attribution. There is no per-request API for the model, user prompt, session id, cwd, user email, API key owner, or local machine identity to influence these fields. - -Wire mapping: - -| Target | Required mapping | -|---|---| -| All HTTP-based adapters | Send `User-Agent` with the product token and version. Include the app URL as a comment only if the final value stays within the conservative syntax in RFC 9110. | -| OpenRouter endpoints | Send `HTTP-Referer`, `X-OpenRouter-Title`, and, when configured, `X-OpenRouter-Categories` in addition to `User-Agent`.

If an existing OpenAI-compatible adapter can be pointed at arbitrary `baseURL` values, it may recognize `https://openrouter.ai/api/v1` exactly or expose an explicit `provider: 'openrouter'`/`attributionTarget: 'openrouter'` config. It should not infer OpenRouter from arbitrary path fragments or model names. - -For the current twin adapters, this means the pi-ai-backed adapter cannot remain a silent exception. Either configure `@earendil-works/pi-ai` with request headers if the library supports that, wrap or contribute the missing hook upstream, or retire the library-backed adapter from product use until it can honor the same attribution contract. The value of the twin is comparing real implementations under one contract; attribution is now part of that contract. - -## Acceptance criteria - -- `dsh-llm` documents the mandatory app-attribution contract for `LlmAdapter` authors. -- A shared helper constructs the default app identity and the standard `User-Agent` value from package metadata, so adapters do not hand-copy `deepseek-harness/0.0.1` constants. -- `dsh-llm-deepseek` sends the shared `User-Agent` on direct DeepSeek requests and keeps the existing mock-server assertion, updated to the shared value. -- The OpenRouter mapping, wherever implemented, sends `HTTP-Referer`, `X-OpenRouter-Title`, and optional `X-OpenRouter-Categories`, with a test that uses an OpenRouter base URL or explicit OpenRouter target and asserts the exact headers. -- `dsh-llm-pi-ai` either sends the same attribution headers through a real library hook or is removed from adapter registration paths with a follow-up RFC explaining why the twin contract no longer justifies the maintenance cost. -- No app-attribution field carries secrets, local paths, session ids, prompt text, model output, user email, or per-user stable identifiers. -- The relevant adapter READMEs mention the attribution policy and the OpenRouter-specific mapping only where that mapping can actually be enabled. - -## Alternatives considered - -**OpenRouter headers everywhere.** Rejected.

ToolSchema.strict was threaded through defineTool, the registry's schemas() allowlist, the deepseek wire mapping, a per-tool payload-patching pass in the pi-ai adapter, and a tool-catalog render row, yet no shipped tool set it and the internal endpoint story for strict mode was never built. Remove both fields end-to-end: the vocabulary in dsh-llm, the adapter guards and wire branches, the dsh-tools threading, the tool-catalog Strict row, the pinning tests, the core.md pastes, the adapter README rows, and the cookbook line that used prefill as the UNSUPPORTED example (now stated generically).

surface + +Status: implemented (accepted 2026-07-04) + +## Context + +The [generated cordis catalog](2026-06-20-generated-cordis-catalog.md) already walks every harness `interface Events` member and every `ctx.<key>` service class with the TypeScript compiler API, and already hard-errors on a missing `@mode` tag — a forcing function that made dispatch modes impossible to leave undocumented. Nothing equivalent guarded the rest of the JSDoc: a service method could ship with no doc at all, and no event or method documented its parameters or return value individually. A survey at adoption found 5 public service methods with no JSDoc and roughly 139 missing `@param`/`@returns` entries across 15 files — on the product API spine (`ctx.bash`, `ctx.fs`, `ctx.sessions`, …) and the cross-plugin event payload contracts, exactly the surface where "what does this argument mean" is the question a plugin author asks the IDE. + +The AGENTS.md rule ("every export has a JSDoc explaining semantics") is prose-checkable only by review; the repo's stated preference is to encode invariants in mechanical gates. The scope "cordis service functions and events" has a precise machine definition that only the catalog generator knows: events are the `interface Events` members inside `declare module 'cordis'`, and the service surface is the public methods of the class each `interface Context` key names. An ESLint rule cannot see that mapping; the generator computes it on every run. + +## Decision + +Extend `scripts/gen-cordis-catalog.ts` — the same walk, the same `@mode` precedent — to enforce JSDoc COMPLETENESS on everything it catalogs. `verify-cordis-catalog` runs inside `doc-sync`, which both CI and the lefthook pre-push hook already execute, so the gate needs zero new wiring (quality-gates principle: one source of truth). + +The contract: + +- **Events** need description prose plus a non-empty `@param` for every **payload parameter**. A payload parameter is a signature parameter that carries event data; the `this` receiver annotation and the trailing waterfall `next` are exempt — `next` is dispatch machinery whose semantics the `@mode waterfall` tag (and its structural cross-check) already owns, so restating it per event would be boilerplate. Documenting an exempt parameter anyway is allowed; only absence is checked. +- **Service classes** need class-level JSDoc, and every public method needs description prose, a non-empty `@param` per parameter, and a non-empty `@returns` unless the annotated return type is `void`/`Promise<void>` (where `@returns` stays optional — resolution timing can be worth documenting — but is never required). +- **Stale tags error**: an `@param` naming no real parameter is a violation, mirroring the `@mode`-contradicts-signature check. Tag descriptions must be non-empty; their semantic quality beyond that is review's job. +- **Explicitness the walk can check**: the gate is a pure-AST pass (no type checker), so a service method must annotate its return type (an inferred return cannot be classified) and surface parameters must be simple identifiers (a binding pattern has no name for `@param` to match). +- **Violations aggregate** into one error listing every offender — a remediation pass sees the whole list at once. The previously fail-fast `@mode` checks moved into the same aggregated report, with their message texts unchanged. + +The tags are **enforcement-only**: `parseJsDoc` now ends description prose at the first block tag (standard JSDoc semantics, which also stops multi-line tag descriptions from leaking into the catalog as prose), so `@param`/`@returns` never change the rendered catalog. Rendering them — restructuring the services section into per-method entries — was considered and deliberately deferred: source JSDoc plus IDE hover is where method docs are consumed, and the catalog stays an index. No escape-hatch tag exists; the surface is small and curated (12 services, 57 methods, 27 events at adoption), and the point is that the check cannot be waved off. + +Negative-path tests in `packages/core/agent/tests/gen-cordis-catalog.spec.ts` drive `collectEvents`/`collectServices` against synthetic fixtures to prove each guard fires and that the exemptions hold. The authoring rule lives in the root [AGENTS.md](../../../../AGENTS.md) conventions bullet alongside the `@mode` rule. + +## Consequences + +- A new event or service method cannot land with an undocumented parameter or result: the generator refuses to regenerate and `verify-cordis-catalog` fails pre-push and in CI. The ~139 gaps found at adoption were filled in the same change, so the gate landed green. +- The service surface must annotate return types explicitly and use identifier parameters. Neither constraint bound at adoption (every method already annotated; no destructured seam parameters existed); both are now load-bearing requirements a violating change will discover mechanically. +- The general AGENTS.md JSDoc rule ("one-liners when one line suffices") acquires a stricter carve-out on this surface: a one-line summary still suffices only when the method has no parameters and a void result. +- `@param` on `next` or `this` stays legal but unchecked — a deliberate asymmetry: the gate enforces the payload contract and refuses to demand boilerplate. +- The rendered catalog is unchanged by the tags (prose stops at the first block tag). If method-level rendering is wanted later, that is a catalog-design decision to take separately, not a gap in this gate. diff --git a/packages/bash/bash/src/index.ts b/packages/bash/bash/src/index.ts index 01c5c081c3..b629f10e4d 100644 --- a/packages/bash/bash/src/index.ts +++ b/packages/bash/bash/src/index.ts @@ -77,16 +77,32 @@ export abstract class BashExecutor extends Service { * call this, then pass the result to {@link run}/{@link start} — keeping * defaulting in the implementation that owns the config while the seam type * stays explicit (no hidden `?? default` inside run/start). + * @param request - the caller's request; omitted fields get this + * implementation's defaults, capped fields are clamped. + * @returns the fully-specified spec to hand to {@link run}/{@link start}. */ abstract resolve(request: BashExecRequest): BashExecSpec - /** Run a command in the foreground; resolves when it finishes. */ + /** + * Run a command in the foreground; resolves when it finishes. + * @param spec - a resolved spec from {@link resolve}, never a raw request. + * @returns the outcome; nonzero exits, timeout kills, and abort kills + * resolve with a descriptive result rather than reject. + */ abstract run(spec: BashExecSpec): Promise<BashRunResult> - /** Start a background task and return its handle immediately. */ + /** + * Start a background task and return its handle immediately. + * @param spec - a resolved spec from {@link resolve}, never a raw request. + * @returns the live task handle; completion fires {@link onTaskDone}. + */ abstract start(spec: BashExecSpec): BashTask - /** Look up a background task by id. */ + /** + * Look up a background task by id. + * @param id - the task id to look up. + * @returns the tracked task, or undefined for an id this executor never issued. + */ abstract get(id: BashTaskId): BashTask | undefined /** @@ -101,24 +117,38 @@ export abstract class BashExecutor extends Service { * loudly at the subsequent {@link readOutput}/{@link kill} ("unknown task"). * Storing ownership in the executor (disposed with ITS fiber) — not in the * tool plugin — is what makes ownership survive a `tool-bash` HMR reload. + * @param id - the background task id to look up ownership for. + * @returns the token recorded at start, verbatim; undefined for an unknown + * id or a known-but-ownerless task. */ abstract ownerOf(id: BashTaskId): OwnerToken | undefined - /** All tracked background tasks (insertion order). */ + /** + * All tracked background tasks (insertion order). + * @returns every task this executor started, running or finished. + */ abstract list(): BashTask[] - /** Read output produced since the previous read.

The field's own JSDoc defines `dialect` as "the bridge that ran it", and native is not a bridge: the [interception-seams RFC](../feature/2026-06-30-interception-seams.md) records that native hooks are not a package and that "a native plugin can already use the typed Decisions" without the durable hook log, and the flagship native-plugin worked example asserts exactly that (no `hook/*` events at all). 2. **`HookOutput.suppressOutput`** (same file) was parsed by the codec and discarded on every path: no bridge branch, no merge fold, no warn, no deferred-list row — uniquely among its parsed-but-unhonored siblings, each of which carries a stated deferral (`updatedInput` → a logged warn plus the [pre-tool-input-rewrite proposal](../../proposed/feature/2026-06-30-pre-tool-input-rewrite.md); `systemMessage` → a logged warn plus a README deferred row; `continue`/`stopReason` → a `TODO(hook-continue-false)` anchor plus the `'stop'` decision record). Structurally there is nothing to suppress: hook stdout never enters any transcript (context flows only via `additionalContext`; the log records only `decision`/`stderrSummary`), so a hook author setting `suppressOutput: true` got silent nothing with no warn. -3. **`hook/result.durationMs`** was durable timing telemetry with no reader. Both bridges wrote it, and the ACP snapshot normalizer scrubbed it to `0` because wall-clock hook runtime is replay noise (`examples/acp-agent/tests/snapshot-normalize.ts`); the remaining consumers were tests and the goldens that existed because the field existed. Deterministic provenance fields (`point`, `matcher`, `turn`, `handlerId`) earn their durability as audit facts; a nondeterministic field that replay must erase and nothing reads earns neither its bytes nor its special-case scrub. -4. **`defaultTimeoutMs` was double-defaulted in both bridge configs** — a schema `.default(600_000)` AND a `?? 600_000` fallback (`packages/hooks/hooks-claude/src/index.ts`, `packages/hooks/hooks-codex/src/index.ts`) — the same two-homes-for-one-literal shape the ACP bridge's `TODO(double-default)` flags, for a knob no shipped config set; the per-hook `timeoutSec` is the real timeout surface. -5. **The `hook/result` semantics lived in the bridges, twice, not in the lib that owns the event.** `summarize()` — the 500-character stderr truncation rule — was byte-identical in `packages/hooks/hooks-claude/src/index.ts` and `packages/hooks/hooks-codex/src/index.ts`, and so was the decision-string rule `output.decision ??

The committed hook fixtures (`session.jsonl`, which double as the expected-log goldens) had the field stripped mechanically; the stdout goldens never carried it. The bridges' `defaultTimeoutMs` config knob is replaced by one reference-default constant, `DEFAULT_HOOK_TIMEOUT_MS` (600 000 ms), exported from the lib's runner and applied inside `runHook`; `RunHookOptions` lost the field entirely, and the per-hook `timeoutSec` stays the override surface. The `hook/result` semantics live in the lib: `HookResultRecord` carries the decoded `HookOutput`, and `appendHookResult` derives `stderrSummary` (500-character truncation) and the decision string from it; both bridges deleted their private copies, and the derived values are byte-identical to what the bridges wrote (the goldens prove it — their only diff is the dropped `durationMs`).

On the tunables, the no-hardcoded-tunables audit set the shape this change keeps: `defaultTimeoutMs` and `stderrSummaryMaxChars` stay explicit bridge configs, and `RunHookOptions.defaultTimeoutMs` stays a required parameter the bridge passes in. What this change adds is one home per literal: the reference defaults live in the lib as `DEFAULT_HOOK_TIMEOUT_MS` (600 000 ms, exported from the runner) and `DEFAULT_STDERR_SUMMARY_MAX_CHARS` (500, exported from the events module), and both bridges' schema defaults and `??` fallbacks read those constants instead of restating the numbers.

The walk enforces JSDoc completeness (every member needs description prose; @mode is rejected as a category error — log events do not dispatch on the cordis bus), derives the surface badge from the SurfaceEventType union with a stale-member cross-check, and hard-errors on duplicate declarations. Payloads render through the TypeScript printer so newline-separated multi-line type literals still emit valid one-line fragments. Documented the five previously JSDoc-less core events (turn/step boundaries, tool/call), removed the two stray @mode tags on the hook/* merges, and replaced the hand-restated event enumerations (session.md hook/* table, compact README table, hook-protocol README bullets, session README name-list — whose merge note had already drifted) with links to the catalog.

Yet the vocabulary had no single reference. The declarations are split across three files — the owning interface in `@deepseek-ai/dsh-session` plus declaration merges in `@deepseek-ai/dsh-compact` and `@deepseek-ai/dsh-hook-protocol` — and the doc surfaces covered it with hand-copies: a `hook/*` payload table in [session.md](../../../core-data-structures/session.md), a `compact/*` payload table in the compact README, payload bullets in the hook-protocol README, and a name-list in the session README. The name-list's merge note had already drifted (it named the compaction merge and omitted the hook merge entirely), and nothing could catch the next merge going undocumented: a hand-copy only checks the names someone already wrote down. This is the same gap the [cordis catalog](2026-06-20-generated-cordis-catalog.md) closed for bus events and the [tool catalog](2026-07-02-tool-schema-catalog.md) closed for model-facing tools — and log events are covered by neither: a `SessionEventMap` member is not a cordis `Events` declaration (it reaches listeners via the single `session/event` emit), so it has no cordis-catalog row by design. + +## Decision + +Generate `docs/persistence-catalog/log-events.md` from source, with a freshness gate, as the fourth reference surface: the *records* a persisted session log can contain, complementing the cordis catalog (wiring), core-data-structures (vocabulary), and the tool catalog (tools). + +`scripts/gen-persistence-catalog.ts` is a pure TypeScript-AST pass, like `gen-cordis-catalog.ts` and unlike the boot-based tool catalog — the right technique because log events ARE statically knowable: every member is a string-literal-named property with a static type annotation, so the AST is the whole truth. The walk collects every `interface SessionEventMap` declaration under `packages/*/*/src` — the owning top-level interface and every `declare module '@deepseek-ai/dsh-session'` merge — so a brand-new event, core or merged, appears in the next regenerate and an un-regenerated file fails `--check` (`verify-persistence-catalog`, a `doc-sync` member, so pre-push and CI both run it). Each entry renders the member's JSDoc prose, its payload (printed through the TypeScript printer, so a newline-separated multi-line type literal still yields a valid one-line fragment), a surface badge, cross-links into core-data-structures, and the declaration's source pointer, grouped by scope. + +Specific choices: + +- **JSDoc completeness, enforced.** Every member must carry description prose — the JSDoc becomes the catalog entry, the same forcing function the cordis catalog applies to bus events. An `@mode` tag on a member is a hard error: dispatch modes belong to cordis bus events, and a log event has none — the tag would misread as "this fires on the bus with mode X". Violations aggregate into one error listing every offender. +- **The surface badge is derived, not hand-listed.** `SurfaceEventType` — the subset that produces LLM messages and may carry `surfaceOp` — is parsed from its union declaration in the owning package; a union member naming no declared event is a hard error (a stale union member would otherwise silently badge nothing). Everything else renders **log-only**. +- **A dedicated fence.** Payload blocks use a ` ```ts persistence-catalog ` info string that `doc-typecheck` recognizes and skips, excluded from the opt-out ratio — the same treatment as `ts cordis-catalog` (a bare payload fragment is not standalone-compilable). +- **Repo scope.** The catalog enumerates the packages in this repo, matching the siblings' packages-only scope; a downstream plugin can merge further event types, which are outside the catalog by construction. Nothing else in the repo may name an interface `SessionEventMap` — the walk treats every such declaration as the merged vocabulary, and a duplicate member across declarations is a hard error. + +This supersedes the hand-copies: the session.md `hook/*` table, the compact README's event table, the hook-protocol README's payload bullets, and the session README's name-list now link the catalog instead of restating payloads (the surrounding semantics prose stays where it was). The two stray `@mode emit` tags on the hook-protocol merge members are removed — the new gate rejects them as the category error they were. + +## Consequences + +- The catalog cannot drift: a vocabulary change the committed file doesn't reflect fails `verify-persistence-catalog` in the pre-push hook and CI, and a new merged event with no JSDoc fails the generator outright — a plugin can no longer add an undocumented on-disk record type. +- Event prose has a single home, the JSDoc at the declaration; thin JSDoc yields a thin catalog entry, pressuring authors to document at the source. +- The `SurfaceEventType` union is now structurally load-bearing for docs: renaming an event without updating the union (or vice versa) fails the generator, not just the compiler. +- The badge derivation assumes the union stays a closed set of string literals with exactly one owner; a refactor away from that shape must update the generator in the same change. diff --git a/package.json b/package.json index 7d136278c6..25c77e24ff 100644 --- a/package.json +++ b/package.json @@ -39,10 +39,12 @@ "verify-cordis-catalog": "tsx scripts/gen-cordis-catalog.ts --check", "gen-tool-catalog": "tsx scripts/gen-tool-catalog.ts", "verify-tool-catalog": "tsx scripts/gen-tool-catalog.ts --check", + "gen-persistence-catalog": "tsx scripts/gen-persistence-catalog.ts", + "verify-persistence-catalog": "tsx scripts/gen-persistence-catalog.ts --check", "gen-module-graph": "tsx scripts/gen-module-graph.ts", "verify-module-graph": "tsx scripts/gen-module-graph.ts --check", "constraints": "tsx scripts/check-workspace-constraints.ts", - "doc-sync": "pnpm run doc-typecheck && pnpm run verify-cordis-catalog && pnpm run verify-tool-catalog && pnpm run verify-md-wrap && pnpm run verify-md-links && pnpm run verify-doc-refs && pnpm run verify-package-paths && pnpm run verify-rfc-classification && pnpm run verify-type-equiv && pnpm run verify-translation-pairing && pnpm run verify-doc-budgets", + "doc-sync": "pnpm run doc-typecheck && pnpm run verify-cordis-catalog && pnpm run verify-tool-catalog && pnpm run verify-persistence-catalog && pnpm run verify-md-wrap && pnpm run verify-md-links && pnpm run verify-doc-refs && pnpm run verify-package-paths && pnpm run verify-rfc-classification && pnpm run verify-type-equiv && pnpm run verify-translation-pairing && pnpm run verify-doc-budgets", "hygiene": "pnpm run knip && pnpm run publint && pnpm run constraints && pnpm run verify-node-next-types", "demo:echo": "node --expose-internals --import tsx packages/ui/stdio-agent/src/bin.ts examples/echo-agent/cordis.yml", "demo:repl": "node --expose-internals --import tsx packages/ui/stdio-agent/src/bin.ts examples/coding-agent/cordis.yml", diff --git a/packages/compact/compact/README.md b/packages/compact/compact/README.md index 424ee12bcf..b49070c3b5 100644 --- a/packages/compact/compact/README.md +++ b/packages/compact/compact/README.md @@ -43,13 +43,7 @@ Compaction is serialized via a log-recorded lock: `compactRegion` refuses to sta ## Events -The `compact/*` events extend `SessionEventMap` (merge-extensible) via declaration merging — they are session events, not cordis `Events`: - -| Event | Payload | On surface? | -|---|---|---| -| `compact/start` | `{ turn }` | no (log-only) | -| `compact/summary` | `{ summary, shadowedRange, shadowedSeqs, shadowedTokenCount }` | no (log-only) | -| `compact/end` | `{ turn, error? }` | no (log-only) | +The `compact/*` events extend `SessionEventMap` (merge-extensible) via declaration merging — they are session events, not cordis `Events`, and all three are log-only (no `surfaceOp`).

The two stray `@mode emit` tags on the hook-protocol merge members are removed — the new gate rejects them as the category error they were. diff --git a/packages/core/session/tests/gen-persistence-catalog.spec.ts b/packages/core/session/tests/gen-persistence-catalog.spec.ts index b5bec1b92e..bc4ab4fbb1 100644 --- a/packages/core/session/tests/gen-persistence-catalog.spec.ts +++ b/packages/core/session/tests/gen-persistence-catalog.spec.ts @@ -78,6 +78,29 @@ describe('gen-persistence-catalog collectLogEvents', () => { }))).toThrow(/top-level interface SessionEventMap .* is outside @deepseek-ai\/dsh-session \(package @deepseek-ai\/dsh-alien\)/) }) + it('hard-errors on a non-exported top-level interface even in the owning package', () => { + expect(() => collectLogEvents(make({ + 'packages/core/fix/package.json': OWNER_MANIFEST, + 'packages/core/fix/src/helper.ts': + 'interface SessionEventMap {\n /** A local helper, not the vocabulary. */\n \'fix/local\': { turn: number }\n}\nexport const use: SessionEventMap | null = null\n', + }))).toThrow(/is not exported; the owning vocabulary is the single exported declaration/) + }) + + it('hard-errors when the owning interface is exported from two files', () => { + expect(() => collectLogEvents(make({ + 'packages/core/fix/package.json': OWNER_MANIFEST, + 'packages/core/fix/src/a.ts': 'export interface SessionEventMap {\n /** First home. */\n \'fix/a\': { turn: number }\n}\n', + 'packages/core/fix/src/b.ts': 'export interface SessionEventMap {\n /** Second home. */\n \'fix/b\': { turn: number }\n}\n', + }))).toThrow(/is already declared at packages\/core\/fix\/src\/a\.ts:1; the owning vocabulary has exactly one home/) + }) + + it('hard-errors on an extends clause (inherited keys would escape the catalog)', () => { + expect(() => collectLogEvents(make({ + 'packages/group/fix/src/types.ts': + 'interface Extra { \'fix/hidden\': { turn: number } }\ndeclare module \'@deepseek-ai/dsh-session\' {\n interface SessionEventMap extends Extra {\n /** Declared directly. */\n \'fix/direct\': { turn: number }\n }\n}\n', + }))).toThrow(/uses extends; inherited keys would join keyof SessionEventMap without a catalog row/) + }) + it('extracts a member declaration-merged via the session module', () => { const events = collectLogEvents(make({ 'packages/group/fix/src/types.ts': merge(' /** Merged provenance. */\n \'fix/merged\': { id: string }'), diff --git a/scripts/gen-persistence-catalog.ts b/scripts/gen-persistence-catalog.ts index 4c58c558d2..6d1988beb7 100644 --- a/scripts/gen-persistence-catalog.ts +++ b/scripts/gen-persistence-catalog.ts @@ -26,9 +26,10 @@ * error — dispatch modes belong to cordis bus events, and a log event has none * (see docs/rfc/implemented/process/2026-07-04-persistence-log-catalog.md). * Structural holes are hard errors for the same reason: a member that is not a - * property signature with an explicit payload type, a top-level - * `interface SessionEventMap` outside the owning package, and a duplicate - * declaration of one event would each let something join (or impersonate) + * property signature with an explicit payload type, an `extends` clause on a + * declaration, a top-level `interface SessionEventMap` that is not the single + * exported declaration in the owning package, and a duplicate declaration of + * one event would each let something join (or impersonate) * `keyof SessionEventMap` without a truthful catalog row.

The tests that exercised a *throwing turn-boundary emit listener* were deleted, because that code path no longer exists (there is no emit to throw from). Per [AGENTS.md "tests document behavior, not golden truth"](../../../../AGENTS.md), the behavior and its test moved (or died) together. - The loop marks the step open (`stepOpen = true`) BEFORE appending `step/start`, because `Session.append` pushes the event to the log before notifying `session/event` listeners (validation throws happen earlier, before the push — see [the session append contract](../../../core-data-structures/session.md)). So a throwing `step/start` session-event listener runs with the step already open and the event already in the log: the loop's outer catch then calls `closeStep()`, which appends the balancing `step/end`, and the turn closes balanced with an error (`turn/start → step/start → step/end → turn/end` — verified by the invariants oracle in the regression test). Closing the open step is owed precisely because the marker is set first. - The full realization of this is [the simplification RFC "Stop mirroring durable boundaries as agent events"](../simplification/2026-06-20-remove-agent-boundary-mirror-events.md): all four boundary mirrors are removed and every consumer reads boundaries off `session/event`. `agent/steering` (not a boundary mirror) stayed outside that RFC's scope and was removed by its own follow-up, [Remove the `agent/steering` mirror emit](../simplification/2026-07-04-remove-agent-steering-mirror.md) — it mirrored the durable `steering/message`. -- The cordis catalog (`docs/cordis-catalog/events-and-services.md`) is regenerated to drop the mirror events. +- The cordis events catalog (`docs/cordis-catalog/events.md`) is regenerated to drop the mirror events. diff --git a/docs/rfc/implemented/process/2026-06-11-doc-sync-enforcement.md b/docs/rfc/implemented/process/2026-06-11-doc-sync-enforcement.md index 8278a1d4b7..ba44b61373 100644 --- a/docs/rfc/implemented/process/2026-06-11-doc-sync-enforcement.md +++ b/docs/rfc/implemented/process/2026-06-11-doc-sync-enforcement.md @@ -13,7 +13,7 @@ AGENTS.md promises that docs and code stay strictly in sync, but the promise was Two gates, mirroring the existing `scripts/` style (tsx ESM, one job each): 1. **`doc-typecheck`** extracts every fenced ` ```ts ` block from `README.md`, `docs/**`, and `packages/*/README.md`, writes them to a temp project extending the root `tsconfig.json`, and compiles it with `tsc -b`.

The leaf no longer carries the cluster, so it has no logger entry to copy wrong by default — the common stdout-purity mistake loses its foothold. (A leaf can still *add* a sibling logger entry — a package cannot forbid what a leaf author writes — so the rule "never add a stdout logger to an ACP leaf" stays documented at the leaf; what changed is that the default leaf has nothing to get wrong.)
