# ACP Agent App Composition
Maintenance mode: hybrid: the leaf plugin list is parsed from its `cordis.yml`; app package expansion is curated from package source.
The ACP demo exposes the same agent spine over JSON-RPC stdio, with no stdout logger and no pre-created agent; clients create sessions through the ACP bridge.

# Agent Turn And Step Lifecycle
Maintenance mode: curated Mermaid sequence; exact event signatures live in the generated Cordis catalog.
This sequence is the visual companion to [architecture.md](architecture.md#loop-lifecycle-session--turn--step). It keeps durable replay facts on `session/event` and live control/status on `agent/*`.
```mermaid

Driver->>Hooks: <code>agent/turn-continuation</code> waterfall
Driver->>Session: <code>turn/end</code>
Driver->>Persistence: <code>session/flush</code> parallel checkpoint
Driver-->>SDK: <code>agent/status</code> idle
```
SDK users that need replayable transcript data should consume `session/event`; `agent/*` is the live coordination surface for queue/status, prompt interception, request shaping, steering, continuation, and errors.

This document describes the architecture of the DeepSeek Harness — the foundation of **DeepSeek Code**. The governing principle, from the [microkernel design discussion][microkernel-doc]: **everything is a plugin**. The core is deliberately tiny — a handful of abstract services plus one concrete loop plugin (`dsh-agent-loop`) — and every product feature is a plugin against the extension surface described here, without modifying the loop.
This document covers **behavior**; type shapes live in [core-data-structures/](core-data-structures/core.md), the per-event/service reference in the [generated catalog](cordis-catalog/events-and-services.md), visual relationship maps in the [documentation graph atlas](graphs/README.md), and per-package contracts in the package READMEs ([map](../packages/README.md)). Requirement context: [Coding Harness MVP 需求分析][mvp-doc].

# Event Producer And Consumer Matrix
Maintenance mode: hybrid generated: Cordis event declarations and most producer/listener edges are AST-scanned; dynamic dispatch sites are classified in `scripts/gen-doc-graphs.ts`.
This matrix shows which packages dispatch each harness-owned event and which packages listen to it. It is intentionally a table rather than one large graph: events are many-to-many, and dense relation data is easier to review in rows. Dynamic dispatch overrides cover sites that deliberately bypass `ctx.emit`, such as subagent lifecycle containment.

# Agent Turn And Step Lifecycle
Maintenance mode: curated Mermaid sequence; exact event signatures live in the generated Cordis catalog.
This sequence is the visual companion to [architecture.md](../architecture.md#loop-lifecycle-session--turn--step). It keeps durable replay facts on `session/event` and live control/status on `agent/*`.
```mermaid

Driver->>Hooks: agent/turn-continuation waterfall

```
SDK users that need replayable transcript data should consume `session/event`; `agent/*` is the live coordination surface for queue/status, prompt interception, request shaping, steering, continuation, and errors.

# App Composition
Maintenance mode: hybrid: leaf plugin lists are parsed from `examples/*/cordis.yml`; bundle expansions are curated from app package source.
This graph is for SDK users asking which pieces a runnable agent loads. Leaf configs choose adapters and optional product tools; app packages provide the front door; `dsh-agent-core` bundles the providerless spine.

# Plugin Disposal And Hot Reload Ownership
Maintenance mode: curated Mermaid flow based on Cordis fiber/effect conventions.
This graph is a maintainer checklist for plugin authors: registrations are effects, service injection gates activation, and owned handles must be disposed by their owner.
```mermaid
flowchart TD
plugin["ctx.plugin(plugin) creates fiber"]
inject["static inject gates activation"]
service["ctx.provide / Service constructor"]
effects["ctx.effect registrations<br/>events, tools, adapters, timers"]
reload["HMR / fiber.dispose()"]
disposers["Run disposers in owner fiber"]
quiescence["Owned AgentHandle.dispose()<br/>or service teardown awaits quiescence"]
plugin --> inject --> service
inject --> effects
reload --> disposers --> quiescence
```
Hook bridges and SDK plugins increase the number of long-lived listeners, so this ownership graph should stay small and visible.

# Package Topology By Group
Maintenance mode: generated from `packages/*/*/package.json` peer dependencies plus package group paths.
This graph complements [module-graph.md](../module-graph.md): it keeps the same canonical peer-dependency edge source, but clusters packages by the `packages/<group>/<pkg>` hierarchy so layering and capability families are easier to scan.

# Subagent And Session Lineage
Maintenance mode: curated Mermaid flow; provider inventory is visible in the generated capability seam graph.
This graph keeps delegation semantics separate from hook observation. A subagent backend creates an ordinary child agent/session through the shared provider registry.
```mermaid
flowchart TD
parent["Parent Agent + Session"]
tool["tool-subagent<br/>model-facing name"]
registry["ctx.subagents provider registry"]
spawn["spawn provider<br/>fresh child session"]
fork["fork provider<br/>seeded from completed-turn prefix"]
acp["ACP provider<br/>out-of-process child"]
child["Child AgentHandle<br/>ordinary Agent lifecycle"]
result["SubagentResult returned to tool"]
parent --> tool --> registry
registry --> spawn --> child
registry --> fork --> child
registry --> acp --> child
child --> result --> parent
```
The hooks stack adds richer lifecycle observation around child runs; the core ownership rule stays the same: the provider owns the child handle and must dispose it.

# Module dependency graph
Inter-package dependencies among the `@deepseek-ai/dsh-*` harness packages, derived from each package's `peerDependencies` (the canonical runtime-dependency signal). An edge `a --> b` means package `a` depends on package `b`. Names have the `@deepseek-ai/dsh-` prefix stripped.
Inter-package dependencies among the `@deepseek-ai/dsh-*` harness packages, derived from each package's `peerDependencies` (the canonical runtime-dependency signal) and grouped by the `packages/<group>/<pkg>` hierarchy. An edge `a --> b` means package `a` depends on package `b`. Names have the `@deepseek-ai/dsh-` prefix stripped.

## Decision
Add a generated graph atlas under [docs/graphs/](../../../graphs/README.md), produced by `scripts/gen-doc-graphs.ts` and verified by `pnpm run verify-doc-graphs` as part of `doc-sync`.
Add generated relationship graph docs, indexed at [docs/graph-atlas.md](../../../graph-atlas.md), produced by focused generators and verified by `pnpm run verify-doc-graphs` / existing catalog freshness checks as part of `doc-sync`.
The atlas is a relationship layer above the existing catalogs. It does not replace exact references; instead, it links to them and explains how their pieces fit together.

### Maintenance modes
@@ -22,36 +22,36 @@ Every graph page declares one maintenance mode:
- **Generated**: all nodes and edges are discovered from source; `--check` fails if the committed artifact is stale.
- **Hybrid generated**: source discovers the inventory, a small manifest classifies irreducible policy, and a completeness guard fails if discovered items are unclassified.
- **Curated**: the diagram explains design intent, temporal order, or ownership; it is emitted by the generator so the atlas remains a single regenerated unit, but the content is deliberately authored.

The first atlas ships twelve files: the index plus eleven graph pages.
The first index links ten relationship surfaces. Package topology and tool-package affordances live in the existing generated catalogs that already own those facts; the remaining focused diagrams are generated by `scripts/gen-doc-graphs.ts`.

### Why one generator
### Why generators own the docs
Keeping the atlas behind one generator gives reviewers one freshness gate and keeps cross-page terminology synchronized. The tradeoff is that curated diagrams are edited in TypeScript string blocks rather than directly in Markdown. That is acceptable for this first cut because the user-facing artifact is still plain Markdown/Mermaid, and a future change can split the curated pages out if authorship ergonomics matter more than one-command regeneration.
Package topology stays in `gen-module-graph.ts`, and tool-package affordances stay in `gen-tool-catalog.ts`, because those generators already own the canonical facts and freshness gates. `gen-doc-graphs.ts` owns the remaining relationship pages and the index. The tradeoff is that curated diagrams are edited in TypeScript string blocks rather than directly in Markdown. That is acceptable for this first cut because the user-facing artifact is still plain Markdown/Mermaid, and a future change can split the curated pages out if authorship ergonomics matter more than regeneration.
### Completeness guards
The hybrid pages must fail loud when their manifests are stale:
- The module graph reads every package's `peerDependencies` and groups each package by its `packages/<group>/<pkg>` path.
- The tool catalog boot-harvests shipped tools and renders the package/service/effect map from the same manifest that its completeness guard already checks.
- The capability seam graph imports the Cordis service collector and asserts every discovered harness `ctx.<key>` is classified in `SERVICE_ROLES`, and every classified key still exists.
- The tool affordance graph boot-harvests the shipped tool catalog and asserts every tool package has `TOOL_PACKAGE_META`.
- The event producer/consumer matrix labels itself hybrid because subagent lifecycle events deliberately use `ctx.events.dispatch` for per-listener containment; those dynamic edges are explicit overrides rather than invisible omissions.
- `verify-mermaid` parses every repo-authored ` ```mermaid ` fence with Mermaid's own parser, so syntax errors fail `doc-sync` locally and in CI instead of showing up as broken GitHub-rendered diagrams.

## Consequences
- Maintainers get visual entry points for topology, seams, event flow, lifecycle, session replay, and snapshot behavior.
- Maintainers get visual entry points for topology, seams, event flow, lifecycle, app composition, and snapshot behavior.
- SDK users get a path from use case to package composition instead of only bottom-up package references.
- `doc-sync` now includes `verify-doc-graphs` and `verify-mermaid`, so graph drift and Mermaid syntax errors are caught with the other doc freshness gates.
- Future fs and hooks work has a concrete place to land new complexity: fs should expand the capability and tool graphs, while hooks should expand the event matrix and tool execution pipeline.

Scope: shipped product tools under `packages/*/tool-*`, each booted with its DEFAULT config. The registered tool NAME can be a load-time config (e.g. `tool-subagent`'s `toolName`), so a deployment may surface a package under a different or additional name — a per-package note records those shipped aliases where they exist. The `examples/` demo tools (e.g. `echo`) are excluded, matching the cordis catalog's packages-only scope.
## Tool Package Map
This table connects model-visible tool names to the plugin package and service seams behind them. Exact JSON Schemas follow in the package sections below.
| Tool package | Model-visible names | Requires | Writes / affects | Shipped aliases | Deployment note |
| --- | --- | --- | --- | --- | --- |
| `@deepseek-ai/dsh-tool-bash` | `bash`, `bash_kill`, `bash_output` | `ctx.tools`, `ctx.bash` | `tool/call`, `tool/result`, `context/message via agent.inject() for background completion notices` | - | The bash/bash_output/bash_kill tools are model-facing consumers of the bash executor seam. |
| `@deepseek-ai/dsh-tool-fs` | `edit`, `read`, `write` | `ctx.tools`, `ctx.fs`, `ctx.systemPrompt` | `tool/call`, `fs/write-intent or fs/edit-intent for mutations`, `fs/observed after successful file operations`, `tool/result` | - | The read-before-write/edit policy is added by `@deepseek-ai/dsh-fs-policy` (an `fs/*` event-gate plugin, no schema change); a deployment that loads these tools is expected to also load it. The tool schemas above are identical with or without the policy plugin. |
| `@deepseek-ai/dsh-tool-subagent` | `subagent` | `ctx.tools`, `ctx.subagents` | `tool/call`, `tool/result`, `child session events through the chosen provider` | `subagent`, `subagent_fork` | The registered tool name is the load-time `toolName` config (default `subagent`); the schema above is that default. The shipped example agents load this package once per subagent backend, so the model additionally sees `subagent_fork` (bound to the fork backend) with an identical schema — see `examples/coding-agent/cordis.yml` and `examples/acp-agent/cordis.yml`. |
| `@deepseek-ai/dsh-tool-todo` | `todo_write` | `ctx.tools`, `owning Agent session` | `tool/call`, `todo/write`, `tool/result` | - | todo_write is session-owned state; UIs render the latest todo/write event as a checklist or ACP plan. |
| `@deepseek-ai/dsh-tool-web` | `web_fetch`, `web_search` | `ctx.tools`, `ctx.web`, `ctx.systemPrompt` | `tool/call`, `tool/result` | - | web_search and web_fetch keep provider selection behind ctx.web so model-visible schemas stay stable across backend swaps. |
