# Cordis Events & Services Catalog

An index reference to the **wiring** a plugin author works against: every cordis event you can listen to (exact signature + dispatch mode) and every `ctx.<key>` service you can call (exact public interface). It complements [core-data-structures/](../core-data-structures/core.md), which catalogs the *data structures* these signatures move around — this page is the verbs, that page is the nouns.

This file is GENERATED from source (`scripts/gen-cordis-catalog.ts`) and verified fresh by `pnpm run verify-cordis-catalog` (part of `doc-sync`) — do not edit it by hand. Signature blocks use a `ts cordis-catalog` fence (skipped by doc-typecheck, since a bare signature is not standalone-compilable). Type names in a signature link to the page that documents them.

The **harness tier** below (the `@deepseek-ai/dsh-*` packages) is the vocabulary this repo owns. The **inherited tier** at the end is the cordis-core + loader/hmr/timer surface a plugin also sees — pinned vendor source, summarized tersely.

## Events

Dispatch modes: **emit** (fire-and-forget), **waterfall** (each listener gets `next()` and may transform or veto — see [waterfall semantics](../architecture.md#cordis-waterfall-semantics-important)), **parallel** (awaited fan-out, no veto). The harness declares 25 events across 7 scopes.

### `agent/*`

#### `agent/created` — emit

An agent was registered in the AgentRegistry and is ready to receive messages.

```ts cordis-catalog
'agent/created'(agent: Agent): void
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:137`](../../packages/core/agent/src/types.ts)

#### `agent/disposed` — emit

An agent was disposed and removed from the registry; its fiber and any in-flight turn have been torn down.

```ts cordis-catalog
'agent/disposed'(agent: Agent): void
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:143`](../../packages/core/agent/src/types.ts)

#### `agent/error` — emit

A step or turn errored. The loop reports a failure here (plus the logger) even when the error has no in-turn position for a session `error` event.

```ts cordis-catalog
'agent/error'(agent: Agent, turn: number, step: number, error: Error): void
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:220`](../../packages/core/agent/src/types.ts)

#### `agent/queued` — emit

A message entered the agent's inbox (queued or steering). `source` is the resolved source (defaults applied), not the caller's raw options.

```ts cordis-catalog
'agent/queued'(agent: Agent, content: ContentBlock[], info: { source: MessageSource; steering: boolean }): void
```

Types: [Agent](../core-data-structures/core.md) · [ContentBlock](../core-data-structures/core.md) · [MessageSource](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:156`](../../packages/core/agent/src/types.ts)

#### `agent/request` — waterfall

Waterfall: mutate the fully-assembled GenerateOptions before the model call (hooks, compaction, model switching, tool filtering, …). Call `next()` to delegate, or return without it to short-circuit.

```ts cordis-catalog
'agent/request'(agent: Agent, turn: number, step: number, options: GenerateOptions, next: () => Promise<GenerateOptions>): Promise<GenerateOptions>
```

Types: [Agent](../core-data-structures/core.md) · [GenerateOptions](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:189`](../../packages/core/agent/src/types.ts)

#### `agent/status` — emit

Agent status changed (`idle` ⇄ `running`, or → `disposed`). Drive lifecycle off this transition, never off a status you just requested — `send()` does not flip status to `running` before it returns.

```ts cordis-catalog
'agent/status'(agent: Agent, status: AgentStatus): void
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:150`](../../packages/core/agent/src/types.ts)

#### `agent/steering` — emit

Steering content was injected into a running turn.

```ts cordis-catalog
'agent/steering'(agent: Agent, turn: number, content: ContentBlock[], source: MessageSource): void
```

Types: [Agent](../core-data-structures/core.md) · [ContentBlock](../core-data-structures/core.md) · [MessageSource](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:214`](../../packages/core/agent/src/types.ts)

#### `agent/step-end` — emit

A step ended.

```ts cordis-catalog
'agent/step-end'(agent: Agent, turn: number, step: number): void
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:180`](../../packages/core/agent/src/types.ts)

#### `agent/step-result` — waterfall

Waterfall: post-process the assembled assistant Message before tool dispatch (validation, content rewriting, …).

```ts cordis-catalog
'agent/step-result'(agent: Agent, turn: number, step: number, message: Message, next: () => Promise<Message>): Promise<Message>
```

Types: [Agent](../core-data-structures/core.md) · [Message](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:195`](../../packages/core/agent/src/types.ts)

#### `agent/step-start` — emit

A step (one model call plus its tool dispatch) began. `step` is 1-based within the turn; a turn runs one or more steps.

```ts cordis-catalog
'agent/step-start'(agent: Agent, turn: number, step: number): void
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:175`](../../packages/core/agent/src/types.ts)

#### `agent/stream-chunk` — emit

A raw StreamChunk arrived from the model (token-level UI/log feed).

```ts cordis-catalog
'agent/stream-chunk'(agent: Agent, turn: number, step: number, chunk: StreamChunk): void
```

Types: [Agent](../core-data-structures/core.md) · [StreamChunk](../core-data-structures/llm-streaming.md)

Source: [`packages/core/agent/src/types.ts:209`](../../packages/core/agent/src/types.ts)

#### `agent/turn-continuation` — waterfall

Waterfall: override the turn-continuation decision. The default (computed by the loop) is `hadToolCalls || steeringInjected`. Listeners can force-continue (/goal, /loop) or force-stop (budget guards).

```ts cordis-catalog
'agent/turn-continuation'(agent: Agent, turn: number, defaultDecision: boolean, next: () => Promise<boolean>): Promise<boolean>
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:202`](../../packages/core/agent/src/types.ts)

#### `agent/turn-end` — emit

A turn ended. `reason` distinguishes a clean stop from a truncated or aborted one (`completed` | `aborted` | `error` | `disposed` | `max-tokens`).

```ts cordis-catalog
'agent/turn-end'(agent: Agent, turn: number, reason: TurnEndReason): void
```

Types: [Agent](../core-data-structures/core.md) · [TurnEndReason](../core-data-structures/session.md)

Source: [`packages/core/agent/src/types.ts:169`](../../packages/core/agent/src/types.ts)

#### `agent/turn-start` — emit

A turn began. `turn` is the 1-based turn number within the session.

```ts cordis-catalog
'agent/turn-start'(agent: Agent, turn: number): void
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/types.ts:163`](../../packages/core/agent/src/types.ts)

### `llm/*`

#### `llm/stream` — waterfall

Waterfall around every streaming model call (retry, caching, routing). Bound to the LlmService; call `next()` to reach the resolved adapter's stream, or yield your own chunks to short-circuit.

```ts cordis-catalog
'llm/stream'(this: LlmService, options: GenerateOptions, next: () => AsyncIterable<StreamChunk>): AsyncIterable<StreamChunk>
```

Types: [GenerateOptions](../core-data-structures/core.md) · [StreamChunk](../core-data-structures/llm-streaming.md)

Source: [`packages/llm/llm/src/index.ts:31`](../../packages/llm/llm/src/index.ts)

### `session/*`

#### `session/created` — emit

A session was created in the store.

```ts cordis-catalog
'session/created'(session: Session): void
```

Source: [`packages/core/session/src/index.ts:33`](../../packages/core/session/src/index.ts)

#### `session/event` — emit

An event was appended to a session log (sync, fire-and-forget). This is the per-append feed a UI or invariant plugin tails.

```ts cordis-catalog
'session/event'(session: Session, event: SessionEvent): void
```

Types: [SessionEvent](../core-data-structures/core.md)

Source: [`packages/core/session/src/index.ts:39`](../../packages/core/session/src/index.ts)

#### `session/flush` — parallel

Awaited durability checkpoint. The agent loop awaits `ctx.parallel('session/flush', session)` at every turn end; persistence plugins (JSONL, SQLite) drain their write-behind buffers here and on fiber dispose. Awaited (parallel), not a waterfall: every listener runs and the loop waits for all of them, but none can veto.

```ts cordis-catalog
'session/flush'(session: Session): Promise<void> | void
```

Source: [`packages/core/session/src/index.ts:48`](../../packages/core/session/src/index.ts)

### `subagent/*`

#### `subagent/end` — emit

A subagent run settled — emitted when SubagentRun.result resolves (any stop reason). Paired with Events['subagent/start'].

```ts cordis-catalog
'subagent/end'(info: SubagentRunEndInfo): void
```

Source: [`packages/subagent/subagent/src/index.ts:65`](../../packages/subagent/subagent/src/index.ts)

#### `subagent/start` — emit

A subagent run started — emitted after the provider is resolved and its capabilities validated, as the child run begins. Paired with Events['subagent/end'].

```ts cordis-catalog
'subagent/start'(info: SubagentRunInfo): void
```

Source: [`packages/subagent/subagent/src/index.ts:59`](../../packages/subagent/subagent/src/index.ts)

### `system-prompt/*`

#### `system-prompt/assemble` — waterfall

Waterfall around prompt assembly — mutate or extend the PromptAssembly (sections + tool schemas) before it is rendered. Bound to the SystemPrompt service; call `next()` to delegate.

```ts cordis-catalog
'system-prompt/assemble'(this: SystemPrompt, assembly: PromptAssembly, next: () => Promise<PromptAssembly>): Promise<PromptAssembly>
```

Source: [`packages/core/system-prompt/src/index.ts:24`](../../packages/core/system-prompt/src/index.ts)

#### `system-prompt/change` — emit

A section or tool provider was registered or unregistered (the assembly inputs changed).

```ts cordis-catalog
'system-prompt/change'(): void
```

Source: [`packages/core/system-prompt/src/index.ts:30`](../../packages/core/system-prompt/src/index.ts)

### `tools/*`

#### `tools/change` — emit

A tool was registered or unregistered (the available tool set changed).

```ts cordis-catalog
'tools/change'(): void
```

Source: [`packages/core/tools/src/index.ts:48`](../../packages/core/tools/src/index.ts)

#### `tools/execute` — waterfall

Waterfall around every tool execution — the single seam where sandbox, permission, hook, and plan-mode plugins wrap or veto a call. Listeners receive `(exec, next)`: call `next()` to proceed (possibly around your own logic), or return a ToolExecutionResult without calling `next()` to short-circuit (veto).

```ts cordis-catalog
'tools/execute'(this: ToolRegistry, exec: ToolExecution, next: () => Promise<ToolExecutionResult>): Promise<ToolExecutionResult>
```

Types: [ToolExecution](../core-data-structures/tools.md) · [ToolExecutionResult](../core-data-structures/tools.md)

Source: [`packages/core/tools/src/index.ts:43`](../../packages/core/tools/src/index.ts)

### `web/*`

#### `web/providers-change` — emit

Fired after the provider registry changes — a search or fetch provider was registered or disposed. Carries no payload and no capability graph: it means only "the provider registry changed; observers may recompute status from `ctx.web`". `searchStatus()` / `fetchStatus()` stay derived, not stored.

```ts cordis-catalog
'web/providers-change'(this: WebService): void
```

Source: [`packages/web/web/src/index.ts:66`](../../packages/web/web/src/index.ts)

## Services

The 11 `ctx.<key>` services the harness provides. An abstract seam (e.g. `ctx.bash`) is implemented by a separate package; the interface is what consumers code against.

### `ctx.agentLoop` — `AgentLoop`

The agent-loop plugin (`ctx.agentLoop`): creates ReactLoopAgents, runs their loops, and registers them in `ctx.agents`. Also implements the AgentFactory seam, so plugins create/resume agents through `ctx.agents` (the interface) without depending on this concrete package.

The loop itself is deliberately thin — every behavior beyond "call the model, run the tools, repeat" belongs to plugins listening on the event taxonomy declared in @deepseek-ai/dsh-agent.

```ts cordis-catalog
create(id: AgentId, options: AgentOptions = {}): ReactLoopAgent
createAgent(options: CreateAgentOptions): AgentHandle
async resume(options: ResumeAgentOptions): Promise<AgentHandle>
```

Source: [`packages/core/agent-loop/src/index.ts:63`](../../packages/core/agent-loop/src/index.ts)

### `ctx.agents` — `AgentRegistry`

Agent registry (`ctx.agents`): tracks live agents so UI, hook, and orchestrator plugins can find them without depending on the concrete loop package. Agent *creation* is provided by whichever plugin implements the AgentFactory (phase 1: `@deepseek-ai/dsh-agent-loop`), registered via setFactory.

```ts cordis-catalog
setFactory(factory: AgentFactory): () => void
create(options: CreateAgentOptions): AgentHandle
async resume(options: ResumeAgentOptions): Promise<AgentHandle>
register(agent: Agent): () => void
get(id: AgentId): Agent | undefined
list(): Agent[]
```

Types: [Agent](../core-data-structures/core.md)

Source: [`packages/core/agent/src/index.ts:117`](../../packages/core/agent/src/index.ts)

### `ctx.bash` — `BashExecutor` (abstract seam)

Abstract bash execution service. Subclass, implement the abstract methods, and load the subclass as a plugin — it registers as `ctx.bash` (one implementation per context; loading a second throws, which is cordis' standard duplicate-service behavior).

Semantics every implementation must honor:

- run REJECTS only for infrastructure failures (unusable workdir, missing shell, pre-aborted signal). Nonzero exits, timeout kills, and abort kills RESOLVE with a descriptive BashRunResult — reporting a failed command is the tool layer's job, not an exception.
- start returns immediately; no timeout applies to background tasks (callers stop them via kill or the spec's AbortSignal). Completion must fire the onTaskDone listeners exactly once per task, and must NOT fire after the service is disposed.
- readOutput is incremental: consecutive reads never re-deliver output. Implementations bound their buffers; reads that lost data flag `lossy` and point at full-stream spill files when available.
- Disposal kills every running task and awaits their exit (no orphan processes survive `fiber.dispose()`).

```ts cordis-catalog
abstract resolve(request: BashExecRequest): BashExecSpec
abstract run(spec: BashExecSpec): Promise<BashRunResult>
abstract start(spec: BashExecSpec): BashTask
abstract get(id: BashTaskId): BashTask | undefined
abstract ownerOf(id: BashTaskId): OwnerToken | undefined
abstract list(): BashTask[]
abstract readOutput(id: BashTaskId): BashTaskRead
abstract kill(id: BashTaskId): boolean
onTaskDone(listener: BashTaskListener): () => void
```

Types: [BashExecRequest](../core-data-structures/bash.md) · [BashExecSpec](../core-data-structures/bash.md) · [BashRunResult](../core-data-structures/bash.md) · [BashTask](../core-data-structures/bash.md) · [BashTaskRead](../core-data-structures/bash.md)

Source: [`packages/bash/bash/src/index.ts:59`](../../packages/bash/bash/src/index.ts)

### `ctx.compact` — `CompactService` (abstract seam)

Abstract compaction service. Subclass implement the two abstract methods, and load the subclass as a plugin — it registers as `ctx.compact` (one implementation per context; loading a second throws, which is cordis' standard duplicate-service behavior).

Both core methods are abstract: the contract states WHAT compaction does, while the entire strategy — token estimation, retention policy, event sequencing, summarization — is a HOW decision owned by the implementation.

Implementations MUST honor:

- **Surface contract**: a successful compaction shadows the compacted surface nodes with a SINGLE replacement node carrying the summary. Because `SurfaceEventType` is a closed union, that node is a `user/message` with `surfaceOp: { op:'replace', start, end }`; the `compact/*` events are log-only (lock + provenance).
- **Blocking**: no compaction begins while another is in progress for the same session. The recommended mechanism is the log-recorded lock — append `compact/start` before the slow work and `compact/end` after (even on failure) — so the lock is visible to replay and crash recovery.

```ts cordis-catalog
abstract compactIfNeeded( session: Session, systemPrompt?: string, model?: string, signal?: AbortSignal, ): Promise<CompactionResult | null>
abstract compactRegion( session: Session, start: number, end: number, model: string, signal?: AbortSignal, ): Promise<CompactionResult>
```

Source: [`packages/compact/compact/src/index.ts:57`](../../packages/compact/compact/src/index.ts)

### `ctx.llm` — `LlmService`

The abstract `llm` service: an adapter registry plus a streaming model-call surface, interceptable via the `llm/stream` waterfall.

```ts cordis-catalog
registerAdapter(models: string[], adapter: LlmAdapter): () => void
models(): string[]
stream(options: GenerateOptions): AsyncIterable<StreamChunk>
```

Types: [GenerateOptions](../core-data-structures/core.md) · [StreamChunk](../core-data-structures/llm-streaming.md)

Source: [`packages/llm/llm/src/index.ts:69`](../../packages/llm/llm/src/index.ts)

### `ctx.sessionPersistence` — `SessionPersistence` (abstract seam)

Abstract durable session-persistence service. Subclass, implement the abstract methods, and load the subclass as a plugin — it registers as `ctx.sessionPersistence` (one implementation per context; loading a second throws, cordis' standard duplicate-service behavior).

Contracts every implementation MUST honor (a DB backend asserts them inside a transaction; a file backend appends at EOF):

- **Append-only; a crashed turn is closed, not truncated.** Committed events — those at or below a flushed `turn/end` — are never rewritten. A crash can leave an unclosed final turn whose events are real (and possibly large); load preserves them and closes the orphaned turn with synthetic boundary events (see load). Only a never-fully-written torn tail fragment is discarded.
- **Contiguous seq.** A persisted log is contiguous: `events[i].seq === i`. load rejects a parse error or a `seq` gap in the COMMITTED region (unloadable); append's first event `seq` MUST equal the backend's stored next-seq (after `load` has balanced any interrupted turn).
- **JSON-serializable data.** `SessionEventMap` is merge-extensible and `event.data` is typed only as `SessionEventMap[K]`, so append REJECTS non-JSON-serializable data with an error naming the offending event type. A backend snapshots (serializes/clones) each event when it buffers, since `session.events` hands out the live mutable object.
- **Durability.** append returns only once the batch is durable (the file backend fsyncs; a DB commits). create MAY defer the physical write until the first append (lazy materialization).

```ts cordis-catalog
abstract create(meta: SessionHeader): Promise<void>
abstract append(id: SessionId, events: readonly SessionEvent[]): Promise<void>
abstract load(id: SessionId): Promise<{ meta: SessionHeader; events: SessionEvent[] }>
abstract list(): Promise<SessionHeader[]>
```

Types: [SessionEvent](../core-data-structures/core.md)

Source: [`packages/session-persistence/session-persistence/src/index.ts:98`](../../packages/session-persistence/session-persistence/src/index.ts)

### `ctx.sessions` — `SessionStore`

In-memory session store (`ctx.sessions`).

Persistence is intentionally not implemented here — persistence plugins subscribe to `session/event` and flush on `session/flush` / dispose.

```ts cordis-catalog
create(id?: SessionId, options?: CreateSessionOptions): Session
prepare(id?: SessionId, options?: CreateSessionOptions): Session
enter(session: Session): () => void
announce(session: Session): void
get(id: SessionId): Session | undefined
list(): Session[]
```

Source: [`packages/core/session/src/index.ts:321`](../../packages/core/session/src/index.ts)

### `ctx.subagents` — `SubagentService`

The `subagents` service: a registry of named SubagentProviders and a capability-checked start surface.

```ts cordis-catalog
registerProvider(provider: SubagentProvider): () => void
getProvider(name: string): SubagentProvider | undefined
list(): string[]
start(name: string, request: SubagentStartRequest): SubagentRun
```

Source: [`packages/subagent/subagent/src/index.ts:103`](../../packages/subagent/subagent/src/index.ts)

### `ctx.systemPrompt` — `SystemPrompt`

Registry service (`ctx.systemPrompt`): plugins contribute ordered text sections and tool-schema providers; the agent loop calls `assemble()` once per step.

```ts cordis-catalog
section(section: PromptSection): () => void
tools(provider: () => ToolSchema[]): () => void
assemble(): Promise<PromptAssembly>
```

Source: [`packages/core/system-prompt/src/index.ts:71`](../../packages/core/system-prompt/src/index.ts)

### `ctx.tools` — `ToolRegistry`

Tool registry (`ctx.tools`): tool plugins register definitions; the agent loop executes calls through the `tools/execute` waterfall. The registry contributes its schemas into the system-prompt assembly.

```ts cordis-catalog
register(definition: ToolDefinition): () => void
get(name: string): ToolDefinition | undefined
schemas(): ToolSchema[]
async execute(exec: ToolExecution): Promise<ToolExecutionResult>
```

Types: [ToolDefinition](../core-data-structures/tools.md) · [ToolExecution](../core-data-structures/tools.md) · [ToolExecutionResult](../core-data-structures/tools.md)

Source: [`packages/core/tools/src/index.ts:277`](../../packages/core/tools/src/index.ts)

### `ctx.web` — `WebService`

The web access service. Registered as `ctx.web` (one instance per context).

Selection semantics (identical for status and execution, never order- dependent):

- A configured id that is registered and `status().available` → that provider.
- A configured id not registered → `configured-missing` / `WEB_PROVIDER_CONFIGURED_MISSING`.
- A configured id registered but unavailable → `configured-unavailable` / `WEB_PROVIDER_CONFIGURED_UNAVAILABLE`.
- No id configured, exactly one registered usable provider → that provider.
- No id configured, multiple usable providers → `ambiguous` / `WEB_PROVIDER_AMBIGUOUS`.
- No id configured, no usable provider → `none` / `WEB_PROVIDER_UNAVAILABLE`.

```ts cordis-catalog
registerSearchProvider(provider: WebSearchProvider): () => void
registerFetchProvider(provider: WebFetchProvider): () => void
searchStatus(): WebCapabilityStatus
fetchStatus(): WebCapabilityStatus
async search(request: WebSearchRequest, exec?: WebExecContext): Promise<WebSearchResult>
async fetch(request: WebFetchRequest, exec?: WebExecContext): Promise<WebFetchResult>
```

## Inherited tier (cordis core + loader/hmr/timer)

The framework surface every plugin inherits, beyond the harness vocabulary above. This is pinned vendor source ([vendoring policy](../../vendor/README.md)); it is summarized here so the catalog is a complete picture of what `ctx` and the event bus offer, without elevating framework internals to the harness tier's prominence.
