Codex, Claude Code, OpenCode, and Kimi Code differ in details, but all separate discovery metadata from complete instructions so a workspace can carry reusable behavior without paying the full prompt cost on every turn. + +DeepSeek Harness needs the same primitive because project-specific review, plugin-authoring, and tool-usage guidance should live next to the workspace or the user's agent configuration instead of being hard-coded into the loop. The repo is still unreleased, so this change establishes the foundation directly as first-class packages rather than a compatibility layer around an older format. + +## Decision + +Add `@deepseek-ai/dsh-skill` as the discovery service (`ctx.skills`) and `@deepseek-ai/dsh-tool-skill` as the model-facing loader tool. `dsh-agent-core` loads both by default so stdio and ACP apps get the same behavior. + +Discovery scans cwd-sensitive project roots, runtime registrations, user roots, extra roots, and system roots in first-wins priority order: project `.dsh`, project `.agents`, runtime, user `.dsh`, user `.agents`, extra roots, then `~/.dsh/skills/.system`. The user `.dsh/skills` scan skips `.system` so built-ins are not discovered twice. Same-name lower-priority skills are ignored with a warning, which lets project and user skills override built-ins deliberately. + +Each skill is either `/SKILL.md` or `.md` with YAML frontmatter. `name` and `description` are required; `whenToUse`, `disableModelInvocation`, and `metadata` are optional. Names are kebab-case. YAML frontmatter is parsed with the `yaml` package instead of a hand-written parser because the format already exposes an open `metadata` object and should behave like ordinary skill files rather than a bespoke key/value subset. + +The service injects a request-time `## Skills` fragment through the existing `agent/request` waterfall. It appends to `GenerateOptions.system` instead of changing `systemPrompt.assemble()`, because the available project skills depend on the calling agent's cwd. The fragment contains only stable routing metadata and is sorted by skill name after first-wins collection, so equivalent workspaces produce deterministic prompt text and better prefix-cache reuse. Full skill bodies are never included in the listing. + +The `skill({ name })` tool loads one full skill for the current agent cwd and returns a `` block with the body plus base-directory guidance. Invalid names, unknown skills, and skills marked `disableModelInvocation` return tool errors. v1 does not additionally inject the loaded body into session context; the tool result is the model-visible disclosure path. + +System skills are ordinary skill files materialized under `~/.dsh/skills/.system` on startup. v1 ships `dsh-plugin-creator` and `dsh-skill-creator` there so the agent can help author DeepSeek Harness plugins and future skills using the same mechanism users can override. + +The data structures and prompt/tool contract are documented in [skills.md](../../../core-data-structures/skills.md), with service signatures in the generated [services catalog](../../../cordis-catalog/services.md). + +## Rejected alternatives + +**Inject full skill bodies into every system prompt.** Rejected because it destroys progressive disclosure and makes every request pay for instructions that may not apply. + +**Expose skills only as slash commands.** Rejected for v1 because model-initiated loading is the core capability; slash/ACP command advertisement can layer on later without changing discovery. + +**Use a separate system-reminder message.** Rejected for the current loop because `agent/request` already owns the last mutation point before the adapter call and `GenerateOptions.system` is the provider-neutral system prompt surface. A later provider-specific surface can still split this fragment if needed. + +**Recursively discover nested `**/SKILL.md`.** Rejected for v1. Flat files and one-level directory bundles cover the configured roots while keeping duplicate handling and prompt order easy to reason about. + +**Hand-parse frontmatter.** Rejected because the accepted schema includes an open `metadata` object. A narrow parser would either reject valid YAML users expect to work or grow into an unreviewed YAML subset. + +## Consequences + +The agent-core spine now includes one more request-time contributor and one more model-facing tool. Skill discovery is cwd-sensitive, so tests and callers that create agents with different session cwd values can observe different project skill overrides by design. + +The prompt fragment is deterministic for a fixed root set and runtime registration revision, but disk changes are not watched; discovery is memoized until runtime registration invalidates the cache or the process restarts. That keeps v1 simple and avoids adding file watching policy before there is a concrete user flow for hot-reloading skills. diff --git a/packages/core/skill/src/index.ts b/packages/core/skill/src/index.ts index 1d1707c722..ace0d9f6eb 100644 --- a/packages/core/skill/src/index.ts +++ b/packages/core/skill/src/index.ts @@ -25,31 +25,46 @@ export function isSkillName(name: string): boolean { return SKILL_NAME.test(name) } +/** Origin bucket for a discovered skill.

Keep answers brief and\nfactual.\n\n\nUse the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.\n\nUse the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\n## Skills\nAvailable skills are listed below. Load a skill with the `skill` tool before following its instructions; do not infer or follow instructions from a skill body that has not been loaded.\n\n\ndescription: Create or update DeepSeek Harness Cordis plugins and packages.\n\n\ndescription: Create or update DeepSeek Harness SKILL.md instructions.\nwhenToUse: Use when writing reusable agent instructions for DeepSeek Harness or adding system/project/user skills.\n\n","tools":[{"name":"subagent","description":"Delegate a self-contained task to a subagent (a separate agent that works in its own context) and return its final result.

Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.\n\nUse the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.\n\nCheck the [exit code: N] marker on every bash result; investigate failures before moving on.\n\n## Skills\nAvailable skills are listed below.

MCP is the emerging standard for tool servers — GitHub, filesystem, databases, code search, and hundreds of community servers expose tools via MCP. Users want to point the harness at one or more MCP servers and have their tools appear as native model-facing tools, without writing per-server glue code. + +The `ToolRegistry` already accepts raw JSON Schema tool definitions (documented in `dsh-tools` README: "Raw JSON-Schema tool definitions (from MCP servers) are still accepted by `ToolRegistry.register()` directly"), and the extension cookbook sketches the intended pattern ("MCP | one plugin per server: discover tools → `ctx.tools.register()`"). The infrastructure is ready; the bridge plugin is missing. + +## Proposal + +### Package + +A single package `@deepseek-ai/dsh-mcp-client` at `packages/mcp/mcp-client/`. No capability-seam three-package split — there is no foreseeable second MCP client implementation, and the convention is "don't split preemptively" ([capability seams RFC](../../implemented/architecture/2026-06-13-capability-seams.md)). + +### SDK + +Use the official [`@modelcontextprotocol/sdk`](https://github.com/modelcontextprotocol/typescript-sdk) (`Client`, `StdioClientTransport`, `StreamableHTTPClientTransport`). The harness does not implement its own JSON-RPC — consistent with how ACP delegates to `@agentclientprotocol/sdk`. + +### Scope + +MCP Client only (no server side — ACP already covers the "expose harness as an agent" role). Bridge **Tools** only — Resources and Prompts are deferred (they require harness-side consumption mechanisms that don't exist yet, and design space is large). + +### Plugin shape + +Namespace plugin (named exports `name`/`inject`/`Config`/`apply`, no `export default`). `inject: ['tools']`. Each MCP server is one plugin instance in `cordis.yml` — the same package loaded N times with different configs, like `dsh-tool-subagent`. + +### Configuration + +Flat discriminated union on the `transport` field: + +```typescript +interface StdioConfig { + transport: 'stdio' + command: string + args?: string[] + env?: Record + cwd?: string + toolPrefix?: string + toolCallTimeoutMs?: number // default 60_000 +} + +interface StreamableHttpConfig { + transport: 'streamable-http' + url: string + headers?: Record + toolPrefix?: string + toolCallTimeoutMs?: number // default 60_000 +} + +type Config = StdioConfig | StreamableHttpConfig +``` + +Example `cordis.yml` usage: + +```yaml +- id: mcp-github + name: '@deepseek-ai/dsh-mcp-client' + config: + transport: stdio + command: npx + args: ['-y', '@modelcontextprotocol/server-github'] + env: + GITHUB_TOKEN: !!js process.env.GITHUB_TOKEN + +- id: mcp-web + name: '@deepseek-ai/dsh-mcp-client' + config: + transport: streamable-http + url: http://localhost:3000/mcp + headers: + Authorization: !!js `Bearer ${process.env.MCP_TOKEN}` +``` + +### Lifecycle + +Boot-time from `cordis.yml`. HMR (`@cordisjs/plugin-hmr`) provides hot-swap: editing the yml entry triggers dispose of the old instance (disconnects, unregisters tools) and creation of a new one (connects, discovers, registers). No runtime-dynamic API for now. + +### Tool discovery and registration + +1. On connect: `client.listTools()` → register each tool as a raw `ToolDefinition` via `ctx.tools.register()`. +2. Listen for `notifications/tools/list_changed` → re-run `listTools()`, diff, unregister removed, register added. +3. Registration uses the raw JSON Schema from MCP (no `defineTool` DSL conversion). +4. No `presentCall`/`presentResult` — the ACP bridge's generic-card fallback handles rendering. +5. Tools are transparent in the system prompt — no "[via MCP]" annotation. + +### Name conflict handling + +If `config.toolPrefix` is set (e.g. `"gh_"`), it is prepended to each MCP tool name before registration. If a name collides with an already-registered tool, log a warning and skip that tool (do not crash the entire server connection). + +### Tool execution + +A unified `execute` handler for all tools from one MCP server: + +1. Call `client.callTool({ name, arguments }, { signal: exec.signal })` with the configured timeout. +2. Map the result: + - Multiple `text` content blocks → join with `'\n'` into a single `TextBlock` (required: `flattenText` uses `join('')` without separator, so multiple blocks would lose inter-block boundaries). + - `image` content blocks → discard with a `ctx.logger.warn` (the harness has no image content block type; [drop-image RFC](../../implemented/simplification/2026-07-04-drop-image-content-block.md)). + - `isError: true` → map to the harness `isError` result path (`{ content: [...], isError: true }`). +3. Cancellation: `exec.signal` (from the agent loop's cancel) is passed through to the MCP SDK's `callTool`, which sends `$/cancelRequest` to the server. + +### Subprocess environment (stdio transport) + +Replicate the `buildChildEnv` + `SENSITIVE_ENV_PATTERN` scrub from `dsh-subagent-acp`: filter ambient env (strip credential-shaped vars matching `/KEY|SECRET|TOKEN/i`), then merge `config.env` on top. Explicit env overrides survive the scrub. + +### Disconnection / crash + +No auto-reconnect. If the MCP server process exits or the transport closes: + +1. The effect disposes → all registered tools are unregistered (fiber-scoped disposers). +2. Subsequent model calls to those tools → `ToolNotFoundError` → `isError: true`. +3. Recovery: user edits `cordis.yml` (triggers HMR reload) or restarts the harness. + +This matches the ACP subagent pattern: "crash = terminal, report error, clean up, don't retry." + +## Alternatives considered + +### MCP Server side (expose harness tools to external MCP clients) + +Deferred. The ACP bridge already exposes the harness as an agent server. Adding an MCP server layer would duplicate that with a different protocol, and the primary user need is consuming external tools, not exposing them. + +### Capability-seam three-package split (interface / impl / consumer) + +Rejected. There is no foreseeable alternative MCP client implementation — MCP has one protocol, one SDK. The convention is "don't split preemptively" until a second implementation appears. + +### Auto-reconnect with exponential backoff + +Rejected for v1. Adds complexity (partial-availability state where tools are registered but temporarily non-functional), and stdio process crashes usually indicate a configuration problem that retrying won't fix. HMR already provides the manual recovery path. Can be added as a future `reconnect: boolean` config if needed. + +### Bridge Resources and Prompts + +Deferred. Resources need a harness-side mechanism to decide WHEN to inject content (system prompt? on demand? model-triggered?). Prompts need a "prompt template" concept the harness lacks. Both require their own design; Tools are the high-value, low-risk starting point. + +### Always-on namespace prefix (e.g. `mcp_github__create_issue`) + +Rejected. Most MCP servers already use semantic prefixes in their tool names (e.g. `github_create_issue`). A forced prefix would break model familiarity with well-known MCP tool names and waste context tokens. Optional `toolPrefix` handles the rare collision case. + +### Preserve multiple TextBlocks in tool result + +Rejected. `flattenText()` in the DeepSeek serializer uses `join('')` (no separator) when flattening `ContentBlock[]` to wire format. Multiple text blocks would silently lose inter-block boundaries — a correctness bug. All existing tools return a single TextBlock; the MCP bridge follows suit. + +## Acceptance criteria + +- A `cordis.yml` entry connecting to an MCP stdio server (e.g. `@modelcontextprotocol/server-filesystem`) results in that server's tools appearing in the model's tool list and being callable. +- A `cordis.yml` entry connecting via Streamable HTTP works equivalently. +- Adding/removing an MCP entry in `cordis.yml` while HMR is active hot-swaps the tools without restart. +- `toolPrefix` config correctly prefixes tool names; a name collision logs a warning and skips. +- Agent cancel propagates to in-flight `callTool` (abort signal). +- Timeout fires and produces an `isError` result when an MCP server hangs. +- Server crash cleanly unregisters tools (no orphaned tool definitions). +- `notifications/tools/list_changed` triggers a re-sync of tool registrations. +- 100% test coverage on the new package (unit tests with mocked MCP SDK). + +## Risks + +- **MCP SDK stability**: the `@modelcontextprotocol/sdk` is still evolving. Breaking changes in the SDK require updating the bridge. Mitigation: pin a specific version; the SDK is widely adopted (Claude Desktop, Cursor, VS Code) so breaking changes are unlikely to be silent. +- **Tool schema quality**: MCP servers may expose poorly-described tools (vague descriptions, incomplete JSON schemas). The harness passes them through as-is — garbage-in-garbage-out. Mitigation: this is the server author's responsibility, not the bridge's. +- **Stdio process management**: a misbehaving MCP server that ignores signals could wedge dispose. Mitigation: the Cordis fiber disposal has bounded quiescence; a stuck transport eventually times out at the framework level. +- **Token budget pressure**: connecting many MCP servers with many tools inflates the system prompt. Mitigation: no different from registering many native tools; the compaction layer handles context pressure. diff --git a/packages/mcp/README.md b/packages/mcp/README.md new file mode 100644 index 0000000000..153afde8a9 --- /dev/null +++ b/packages/mcp/README.md @@ -0,0 +1,7 @@ +# MCP — Model Context Protocol + +Packages bridging the harness to the MCP ecosystem. + +| Package | Role | +|---|---| +| `mcp-client/` | MCP client bridge: connects to external MCP servers and registers their tools on `ctx.tools` | diff --git a/packages/mcp/mcp-client/README.md b/packages/mcp/mcp-client/README.md new file mode 100644 index 0000000000..68f6ebf42a --- /dev/null +++ b/packages/mcp/mcp-client/README.md @@ -0,0 +1,57 @@ +# @deepseek-ai/dsh-mcp-client + +MCP client bridge plugin: connects to external [Model Context Protocol](https://modelcontextprotocol.io/) servers and registers their tools on `ctx.tools`, making them available to the model as native tools. + +## Usage + +One plugin instance per MCP server in `cordis.yml`: + +```yaml +- id: mcp-github + name: '@deepseek-ai/dsh-mcp-client' + config: + transport: stdio + command: npx + args: ['-y', '@modelcontextprotocol/server-github'] + env: + GITHUB_TOKEN: !!js process.env.GITHUB_TOKEN + +- id: mcp-web + name: '@deepseek-ai/dsh-mcp-client' + config: + transport: streamable-http + url: http://localhost:3000/mcp + headers: + Authorization: !!js '`Bearer ${process.env.MCP_TOKEN}`' +``` + +HMR hot-swaps: editing the entry triggers disconnect + reconnect without process restart. + +## Config + +| Field | Transport | Required | Description | +|---|---|---|---| +| `transport` | both | yes | `"stdio"` or `"streamable-http"` | +| `command` | stdio | yes | Executable to spawn | +| `args` | stdio | no | Arguments passed to the command | +| `env` | stdio | no | Extra env vars merged on top of scrubbed ambient env | +| `cwd` | stdio | no | Working directory for the child process | +| `url` | http | yes | MCP server URL | +| `headers` | http | no | Extra headers (e.g. auth tokens) | +| `toolPrefix` | both | no | Prefix prepended to each tool name before registration | +| `toolCallTimeoutMs` | both | no | Timeout per `callTool` invocation (default 60000) | + +## Behavior + +- On connect: `listTools()` → registers each tool via `ctx.tools.register()`. +- Listens for `notifications/tools/list_changed` → re-syncs tool registrations. +- Tool execute: `client.callTool({ name, arguments }, { signal })` with timeout + abort support. +- Image content in results is discarded with a warning (the harness has no image block type). +- On disconnect/crash: all tools are unregistered; no auto-reconnect. +- Name conflicts: if a tool name collides, it is skipped with a warning.

Skill discovery is cwd-sensitive, so tests and callers that create agents with different session cwd values can observe different project skill overrides by design. The prompt fragment is deterministic for a fixed root set and runtime registration revision, but disk changes are not watched; discovery is memoized until runtime registration invalidates the cache or the process restarts. That keeps v1 simple and avoids adding file watching policy before there is a concrete user flow for hot-reloading skills. diff --git a/examples/acp-agent/tests/snapshots/cancel/session.jsonl b/examples/acp-agent/tests/snapshots/cancel/session.jsonl index 837a4ae788..662ec035d0 100644 --- a/examples/acp-agent/tests/snapshots/cancel/session.jsonl +++ b/examples/acp-agent/tests/snapshots/cancel/session.jsonl @@ -2,7 +2,7 @@ {"type":"turn/start","seq":0,"time":0,"data":{"turn":1,"trigger":{"kind":"message","source":{"kind":"user"}}}} {"type":"user/message","seq":1,"time":0,"data":{"content":[{"type":"text","text":"Start a long task; this turn will be cancelled mid-stream."}],"source":{"kind":"user"}},"surfaceOp":"append"} {"type":"step/start","seq":2,"time":0,"data":{"turn":1,"step":1}} -{"type":"request/header","seq":3,"time":0,"data":{"header":{"config":{"model":"deepseek-v4-flash"},"system":"You are an AI agent powered by the DeepSeek Harness SDK.\n\nYou are a coding assistant powered by the deepseek-v4-flash model.

+1,38 @@ # @deepseek-ai/dsh-skill -Agent skill discovery and model-facing skill guidance. +Agent skill provider registry and model-facing skill guidance. + +This package owns the `ctx.skills` interface. It does not know whether skills come from local files, embedded plugin data, HTTP, or another backend; providers register those sources with `ctx.skills.registerProvider(...)`. The shipped local implementation is [`@deepseek-ai/dsh-skill-local`](../skill-local). ## Service: `SkillService` (ctx key: `skills`) ### Public API -- `ctx.skills.list({ cwd? })` Returns model-invocable skill summaries for the current workspace. -- `ctx.skills.get(name, { cwd? })` Returns the full skill, including disabled-for-model skills. -- `ctx.skills.register(skill): () => void` Registers a runtime skill, disposed with the calling fiber. Same-name runtime registrations are first-wins: a duplicate logs a warning and gets a no-op disposer. +- `ctx.skills.registerProvider(provider): () => void` Registers a provider by unique `provider.name`. Duplicate provider names throw, and `runtime` is reserved for `ctx.skills.register(...)`. The registration is effect-scoped and HMR-safe. +- `ctx.skills.list({ cwd? })` Returns model-invocable skill summaries for the current workspace, merged across providers. +- `ctx.skills.get(name, { cwd? })` Returns the full winning skill, including disabled-for-model skills. +- `ctx.skills.register(skill): () => void` Registers a runtime embedded skill. Same-name runtime registrations are first-wins: a duplicate logs a warning and gets a no-op disposer. +- `ctx.skills.renderModelListing({ cwd? })` Renders the request-time `## Skills` catalog. ### Config | Field | Default | Meaning | |---|---|---| -| `dshHome` | `$DSH_HOME` or `~/.dsh` | DeepSeek Harness config root; system skills live under `skills/.system`. | -| `agentsHome` | `$DSH_AGENTS_HOME` or `~/.agents` | Shared agent config root scanned for compatible skills. | -| `extraRoots` | `[]` | Additional skill roots scanned after user roots and before system skills. | -| `installSystemSkills` | `true` | Whether startup materializes bundled system skills under `dshHome`. | | `promptFieldMaxLength` | `500` | Maximum rendered `description` / `whenToUse` length in the prompt listing; must be at least `3` because truncated fields reserve `...`. | -| `collectCacheMaxEntries` | `128` | Maximum cwd/root discovery promises kept in memory. | +| `collectCacheMaxEntries` | `128` | Maximum cwd/provider discovery promises kept in memory. | -### Discovery +## Provider Contract -Default roots are resolved in this conflict priority order: +A provider returns `SkillCandidate[]` from `list(options)` and later receives the winning candidate back in `get(candidate, options)`. The candidate's `locator` is opaque to the registry, so a local provider can store a file path while a future HTTP provider can store a URL, id, or version token. -| Source | Path | -|---|---| -| Project DSH | `/.dsh/skills` | -| Project agents | `/.agents/skills` | -| Runtime | `ctx.skills.register(...)` | -| User DSH | `~/.dsh/skills` | -| User agents | `~/.agents/skills` | -| Extra | `Config.extraRoots` | -| System | `~/.dsh/skills/.system` | +The registry validates candidate names, descriptions, ranks, and provider ownership. Candidate contract violations fail fast because the provider plugin is malformed; a provider `list()` rejection is treated as a transient source failure, logged, skipped for that request, and not cached. Duplicate skill names are resolved first-wins by `rank`, provider registration order, then the provider's own local order. The final model-visible summary list is sorted by skill `name` for deterministic prompt text and provider prefix-cache friendliness. -The project root is the nearest ancestor containing `.git`; without one, the current cwd is used. When `ctx.fs` is available, that ancestor lookup probes `.git` through the filesystem service rather than the host filesystem so remote or sandboxed workspaces keep their own project boundary. The user DSH root skips `.system` during normal user scanning so system skills are read exactly once. Same-name skills keep the highest-priority copy, then model-visible summaries are sorted by skill name for stable prompts and provider prefix-cache friendliness. +## Runtime Skills -When `ctx.fs` is available, discovery lists roots through `ctx.fs.listDir`, reads skill files through `ctx.fs.readText`, and installs system skills through `ctx.fs.writeText`. Without a filesystem service, the package falls back to Node filesystem I/O for project-root lookup, discovery, reads, and installation so the service can still run in minimal test contexts. Missing, unreadable, or malformed skill files warn and skip instead of failing the whole request. - -Discovery is memoized per resolved root set and runtime-skill revision. Runtime `register()` and active disposer calls invalidate the cache; duplicate runtime registrations do not alter the active set. Disk-only changes are picked up on the next invalidation or process restart. - -## Skill Format - -Skills can be single-level directory bundles (`/SKILL.md`) or flat Markdown files (`.md`). Nested `**/SKILL.md` discovery is intentionally not part of v1. Frontmatter is parsed as YAML with the `yaml` package; it requires `name` and `description`, while `whenToUse`, `disableModelInvocation`, and `metadata` are optional. Names must be kebab-case. +`ctx.skills.register(...)` is a convenience for embedded runtime skills. Runtime skills use rank `250`: project providers can override them, while they override the shipped local provider's custom and user roots. Runtime registration is also first-wins within runtime contributions, so a duplicate contribution cannot remove the active one through its disposer. ## Prompt Integration -The service listens on `system-prompt/assemble` and appends a short `## Skills` section to the calling agent's assembled system prompt. The listing contains only stable routing metadata (`name`, `source`, `description`, and optional `whenToUse`), not skill bodies or local absolute paths. `description` and `whenToUse` are whitespace-normalized and capped in the listing so one pathological skill cannot bloat every model request. Models load full instructions through the `skill` tool. +The service listens on `system-prompt/assemble` and appends a short `## Skills` section to the calling agent's assembled system prompt. The listing contains only stable routing metadata (`name`, `source`, `description`, and optional `whenToUse`), not skill bodies or absolute local paths. `description` and `whenToUse` are whitespace-normalized, capped, XML-escaped, and have `{{` / `}}` delimiters split so provider text cannot trip prompt-variable interpolation. Models load full instructions through the `skill` tool. -## System Skills - -On startup, the service ensures bundled system skills exist under `~/.dsh/skills/.system` unless `installSystemSkills: false` is configured. Project, runtime, user, and extra-root skills can override system skills by name. +The prompt-injection surface is intentionally separate from provider loading: changing where skills come from means adding or swapping providers, not changing prompt assembly or the `skill` tool. diff --git a/packages/core/skill/package.json b/packages/core/skill/package.json index fade69a580..82a43dd6a0 100644 --- a/packages/core/skill/package.json +++ b/packages/core/skill/package.json @@ -1,6 +1,6 @@ { "name": "@deepseek-ai/dsh-skill", - "description": "Agent skill discovery and prompt listing for the DeepSeek Harness", + "description": "Agent skill provider registry and prompt listing for the DeepSeek Harness", "version": "0.0.1", "private": true, "type": "module", @@ -23,19 +23,14 @@ "license": "BSD-3-Clause", "peerDependencies": { "@deepseek-ai/dsh-agent": "^0.0.1", - "@deepseek-ai/dsh-fs": "^0.0.1", - "@deepseek-ai/dsh-llm": "^0.0.1", "@deepseek-ai/dsh-system-prompt": "^0.0.1", "cordis": "^4.0.0-rc.6" }, "dependencies": { - "schemastery": "^3.18.0", - "yaml": "^2.4.2" + "schemastery": "^3.18.0" }, "devDependencies": { "@deepseek-ai/dsh-agent": "workspace:^", - "@deepseek-ai/dsh-fs": "workspace:^", - "@deepseek-ai/dsh-llm": "workspace:^", "@deepseek-ai/dsh-system-prompt": "workspace:^", "cordis": "^4.0.0-rc.6" } diff --git a/packages/core/skill/src/index.ts b/packages/core/skill/src/index.ts index eeca83b852..77b54f0929 100644 --- a/packages/core/skill/src/index.ts +++ b/packages/core/skill/src/index.ts @@ -1,27 +1,25 @@ /** - * Agent skill discovery and prompt listing. + * Agent skill registry and request-time catalog rendering. * - * Skills are progressive-disclosure instructions: the model sees only a short - * listing in the system prompt, then calls the `skill` tool to load the full - * `SKILL.md` body when a task matches. + * This package is the interface third of the skill capability seam.

The model cannot compose tools — loop over a result set, branch on an intermediate value, fan out, post-process — without a full model round-trip per call, and each round-trip drags the entire intermediate result back into context whether the model needs it or not. + +Cloudflare's [Code Mode](https://blog.cloudflare.com/code-mode/) proposes an alternative grounded in a simple observation: LLMs are better at writing code than at emitting tool calls, because they have seen millions of lines of real code and comparatively few contrived tool-calling traces. Instead of one tool call per step, the model writes a TypeScript program against a generated API over the tools, the program executes in a sandboxed runtime, and the model curates what comes back — only what it prints or returns — instead of every intermediate result. + +An earlier draft of this RFC designed Code Mode as an add-on consumer plugin with zero core changes, deferring the execution substrate to a follow-up. Both constraints are dropped here, deliberately. First, the harness is pre-release and optimizes for the correct foundation over blast radius: tool presentation is the registry's own concern, and bolting a second presentation onto it from outside means transforming the registry's contribution after the fact — a waterfall listener whose correctness depends on listener ordering, which fights the [reconstructable-requests](../../implemented/architecture/2026-07-05-reconstructable-requests.md) design instead of riding it (that refactor removed request mutation from `agent/request`, the seam the old draft relied on). Second, the substrate question is answerable now: a Node `worker_threads` runtime gives real containment — separate isolate, empty environment, heap caps, and a `terminate()` that reliably stops a hot synchronous loop — where the old draft's `node:vm` stub had none of those, and it fits the harness's existing trust model (§Trust posture) without a hardening follow-up. + +## Proposal + +Three decisions, each elaborated in its own section below: + +1. **Code Mode is a first-class presentation mode of `ToolRegistry`** (`dsh-tools`), selected by a validated `mode` config: `'native'` (today's behavior, the default), `'code'` (the wire carries exactly one tool, `run_code`, plus a generated SDK `.d.ts` in the system prompt), or `'both'` (native schemas *and* `run_code` + SDK). The registry's existing tool-schema provider contributes whatever the mode dictates, so the wire tool list is shaped at its source — no interception, no listener-ordering caveats — and the logged request header records it for free. +2. **Code execution is a capability seam** — a new group `packages/code-runtime/` with the interface package `@deepseek-ai/dsh-code-runtime` owning `ctx.codeRuntime` ([capability seams](../../implemented/architecture/2026-06-13-capability-seams.md); consumer = `dsh-tools`, with core-consumes-a-seam precedent in `agent-loop` → `dsh-llm`). The runtime knows nothing about tools: it is handed a program and named async bindings, runs the program, and reports `{ value, logs, error? }`. Language and substrate are backend properties, so a future Python or container backend is a new implementation package, not a redesign. +3. **The shipped implementation is `@deepseek-ai/dsh-code-runtime-worker`**: one fresh Node worker thread per run, executing the model's TypeScript after type-strip, with bindings bridged over the message port, an empty environment, configurable heap/output/time caps, and hard termination. Its trust posture is bash-equivalent by design — no unsafe-acknowledgement flags — because the harness already ships `dsh-bash-local`, which executes arbitrary model-written shell commands with strictly *more* ambient authority. + +### The registry owns the mode + +`ToolRegistry` gains a schemastery-validated config (`static Config`), its first: `mode: 'native' | 'code' | 'both'`, default `'native'`. A deployment flips it from `cordis.yml` (`tools: { mode: code }`) — no code edit, per the no-hardcoded-tunables convention. + +**Wire tool list = the provider's contribution.** The registry already feeds the assembly through `ctx.systemPrompt.tools(() => this.schemas())`; the provider becomes mode-aware: `'native'` contributes all schemas (unchanged), `'code'` contributes only `run_code`'s schema, `'both'` contributes all schemas plus `run_code`. Because [`PromptAssembly.tools` is the single source the loop's request header snapshots](../../../../packages/core/system-prompt/src/index.ts), the collapse is automatically logged and reconstructable — model-visible ⟺ logged holds with zero new mechanism, and there is no seam left where another party could accidentally re-add tools (the `system-prompt/assemble` waterfall can still deliberately transform the assembly, as ever). + +**Interaction with `toolOrder`, stated up front:** a configured `systemPrompt.toolOrder` naming native tools rejects every assembly under `mode: 'code'` (those names are no longer contributed), by the existing fail-loud rule for unlisted names. This is correct behavior, not a bug: a deployment switching modes updates its order config or drops it. + +**The SDK prompt section.** Under `'code'` and `'both'` the registry registers one lazy prompt section (`tools:sdk`, in the 100–199 tool-guidance order band) whose thunk regenerates, at each assembly, a TypeScript declaration of every registered tool except `run_code` itself, plus fixed usage instructions. The thunk reads the live store and emits tools in lexicographic name order, so its output is deterministic and stable across steps — an unchanged tool set produces byte-identical text (prefix-cache-friendly; a mid-session registration surfaces as one logged header delta, exactly like a native-mode tool change). + +**Codegen.** A pure `jsonSchemaToTs(schema)` module inside `dsh-tools` (sibling of `json-schema.ts` — `schemas()` and the SDK are two projections of the same store) maps the JSON-Schema subset the `defineTool` DSL emits (object/string/number/boolean/array, `properties`, `required`, string `enum` → literal union, nested objects, array `items`, `description` → JSDoc) to a TS type literal. It is **total**: any construct outside that subset (`$ref`, `oneOf`/`anyOf`, `integer`, future MCP shapes, …) degrades to `unknown` without throwing. Because `ToolSchema.name` is an arbitrary string, the SDK is declared as one object constant — `declare const tools: { "some-mcp-tool"(args: …): Promise; bash(args: …): Promise; … }` — quoted keys make every name reachable with no sanitization or alias-collision logic. Typing is advisory (the runtime executes type-stripped JS); the instructions say so. + +### The run_code tool and the dispatch bridge + +Under `'code'` and `'both'` the registry registers `run_code` in itself as an ordinary tool — one required parameter `{ code: string }` — so the unchanged loop dispatches it through the normal pipeline and `tools/pre-execute` / `tools/post-execute` gate it like any other call (a permission plugin can inspect the program text before it runs). Its `execute(args, exec)`: + +1. **Builds the bindings**: for every registered tool except `run_code`, an async function that (a) checks `exec.signal?.aborted` before and after (throwing stops the program — necessary because `ctx.tools.execute()` converts errors to `isError` data), (b) awaits its turn on the **per-run serialization queue** (below), (c) calls `this.execute({ callId, name, arguments, agent: exec.agent, signal: exec.signal })` with a deterministic sub-id `` CallId(`${exec.callId}:code:${n}`) ``, (d) appends a `tool/code-dispatch` session event, and (e) maps the result: success → the text-block contents joined as a `string` (non-text blocks become placeholders, an MVP limitation), `isError` → **the binding rejects** with an `Error` carrying the result text. Rejection is the deliberate model-facing contract — real code signals failure by throwing, `try/catch` and `Promise.all` short-circuiting behave as every model has seen them behave — where the old draft's `{ output, isError }` envelope made error handling a bespoke convention. +2. **Runs the program**: `ctx.codeRuntime.run({ program: args.code, bindings: [{ global: 'tools', functions }], signal: exec.signal })`. +3. **Surfaces the outcome**: a successful run returns one text block — the captured console/stdout output followed by the rendered return value (if any) — plus a `meta` payload (capped logs, dispatch count) for presentation. A run with `result.error` throws a `CodeRunFailedError extends HarnessError` (`code: 'CODE_RUN_FAILED'`, message = the error kind and text plus captured logs so the model can self-correct); the registry's existing catch turns it into a structured `isError` result. + +**Concurrency: serialized, enforced by the binding.** The bindings are async, so a model writing `Promise.all([tools.a(…), tools.b(…)])` starts both immediately — concurrent dispatch would be the *default*, while the tool contract still carries no concurrency-safety metadata (the open parallel-execution TODO). Each `run_code` invocation therefore owns a dispatch queue and every binding call chains onto it, so even `Promise.all` executes the underlying `ctx.tools.execute()` calls one at a time in submission order; when the run settles, queued-but-unstarted dispatches are abandoned. Lifting this per-tool once tools can declare themselves concurrency-safe is deferred work, same as before. + +**Presentation.** `run_code`'s render intent is decided here per the [render-intent RFC](../../implemented/architecture/2026-07-02-tool-render-intent-union.md): `presentCall` → a `generic` card, `kind: 'execute'`, title `Run code`, `rawInput` = the program text; `presentResult` → a `generic` card whose content is the captured output (from `meta`). Not a `terminal` card: that card's semantics are "a shell command in a working directory", which a program is not. + +### Observability: `tool/code-dispatch` + +Each sub-dispatch appends one session event, declared by `dsh-tools` via `SessionEventMap` declaration merging (the map is merge-extensible for exactly this): `tool/code-dispatch` with `{ parentCallId, subCallId, name, arguments, isError, resultSummary }`. It is log-only — `deriveEventMessage()` ignores unknown event types by design, so sub-calls never re-enter model context — but persistence and UIs get every call. A `run_code` execution arriving without `exec.agent` (the loop always supplies it; direct programmatic calls may not) still runs and simply skips event logging, exactly as the `ToolExecution` contract allows. + +### The code-runtime seam + +`packages/code-runtime/code-runtime/` — `@deepseek-ai/dsh-code-runtime`, depending only on `cordis`. An abstract `CodeRuntime extends Service` (`super(ctx, 'codeRuntime')`) plus the vocabulary: + +- `CodeRunRequest = { program: string; bindings: CodeBindingNamespace[]; signal?: AbortSignal }` +- `CodeBindingNamespace = { global: string; functions: Record Promise> }` — the runtime exposes each namespace as a global object of async functions inside the program; binding arguments and resolutions must be structured-cloneable (a runtime may cross a serialization boundary; ours does). +- `CodeRunResult = { value?: unknown; logs: CodeLogEntry[]; error?: CodeRunFailure }` — an error is a field on a resolved result, never a rejection of `run()`. +- `CodeLogEntry = { source: 'console' | 'stdout' | 'stderr'; level?: 'log' | 'info' | 'warn' | 'error' | 'debug'; text: string }` +- `CodeRunFailure = { kind: 'exception' | 'timeout' | 'abort' | 'worker-exit'; message: string }` — orthogonal outcomes reported independently per [defensive patterns](../../../defensive-patterns.md); a timed-out run is not an exception, an abort is not a timeout. +- Two readonly backend descriptors, informational not gating: `language` (what the program must be written in — `'typescript'` for the shipped backend; a Python backend would say so, and pair with its own SDK generator on the presentation side) and `isolation` (`'worker-thread'` for the shipped backend; `'process'`, `'container'`, … for future ones). `dsh-tools` requires `language === 'typescript'` in the MVP — its codegen emits TS — and fails the assembly loudly otherwise, the same misconfiguration idiom as `toolOrder` violations (as when `mode` is non-native with no `ctx.codeRuntime` loaded at all). + +Per explicit-over-implicit at seams, the request spells out everything the runtime acts on; defaulting (timeouts, caps) is the implementation's validated config, never a hidden `??` inside `run()`. The seam split is justified by real planned divergence on both axes — substrate (worker now; container/microVM later) and language (the Python/AssemblyScript direction sketched in the earlier draft survives as future work) — not by speculation: `dsh-tools` consumes the interface today and tests against a trivial in-repo fake, exactly the interface/implementation/consumer shape of the bash template. + +### The worker-thread runtime + +`packages/code-runtime/code-runtime-worker/` — `@deepseek-ai/dsh-code-runtime-worker`. Per `run()`: + +1. **Type-strip host-side** with Node's built-in `stripTypeScriptTypes` (`node:module`; the repo floor is node ≥ 24, and the API is position-preserving, so runtime error line numbers match the model's source). Strip-only mode rejects non-erasable syntax (`enum`, namespaces) — that rejection returns as `error.kind: 'exception'` with Node's message, the SDK instructions say "erasable TypeScript only", and the model self-corrects like any other program error. A syntax-level failure never spawns a worker. +2. **Spawn one fresh `Worker` per run** from the package's own bootstrap module: `env: {}` (truly empty — stronger than the scrubbed-env rule for spawned commands), `resourceLimits` from config, `stdout`/`stderr` captured into `logs` rather than inherited. No pooling and no cross-run state: a program's world dies with its worker, which keeps runs reconstructable from the log alone and makes state bleed unrepresentable. +3. **Execute** in the bootstrap: the stripped program becomes the body of an `AsyncFunction` whose parameters are the binding globals and a capturing `console` shim, so top-level `await` and `return` work and the program's completion value is the run's `value` (structured-cloneable values cross as-is; anything else is replaced by its `util.inspect` rendering, documented). +4. **Bridge bindings over the message port**: each binding function in the worker posts `{ id, global, name, args }` and awaits the reply; the host validates the name against the request's bindings, invokes, and replies `{ id, ok, value }` or `{ id, ok: false, message }` (a host-side binding rejection becomes a program-side rejection). Unknown names, duplicate ids, and post-settlement messages are rejected or ignored — the port protocol assumes a hostile peer, because the peer runs model code. +5. **Enforce caps**: the compute-time budget (`timeoutMs`) ticks only while no binding call is pending — it bounds runaway worker compute, not tool latency — and expiry, `signal` abort, and run completion all funnel into `worker.terminate()`, which ends hot synchronous loops too (measured; this was `node:vm`'s unfixable gap). Heap overflow surfaces as the worker's OOM exit → `error.kind: 'worker-exit'`. Log and value sizes are capped by config (`maxLogBytes`, `maxValueBytes`), truncation marked in-band. All caps are validated config fields with defaults (`timeoutMs: 60_000`, `maxLogBytes: 65_536`, `maxValueBytes: 32_768`, `maxOldGenerationSizeMb: 512`), changeable from `cordis.yml`. +6. **Dispose to quiescence**: the service's own disposal terminates in-flight workers and *awaits* their exits before resolving, per [defensive patterns](../../../defensive-patterns.md). + +### Trust posture + +The worker runtime is **containment, not a security boundary**, and the RFC says so without ceremony. Model code in the worker can reach Node globals — `fetch`, `process` (with an empty env) — so a deliberately adversarial program has ambient authority comparable to what the harness's own `bash` tool already grants every model turn: `dsh-bash-local` runs arbitrary model-written commands with the host filesystem, network, and a scrubbed-but-populated environment. Code Mode is gated where bash is gated — `tools/pre-execute`, where permission/sandbox plugins veto or approve the program before it runs — and adds containment bash does not have: empty env, heap caps, hard termination, a separate isolate. The earlier draft's two-flag unsafe ceremony (`{ unsafe: true }` constructor + `allowUnsafeRuntime`) existed for a `node:vm` stub with *no* containment and is dropped with it; demanding scarier flags for the better-contained executor than for bash would be posture theater. A deployment that needs a hard boundary (untrusted multi-tenant input) needs it for bash too; that is a future `isolation: 'container'` backend, and the `isolation` descriptor exists so such a deployment can tell backends apart. + +### What the model sees + +The `tools:sdk` section carries the `.d.ts` plus fixed instructions: the program is the body of an async TypeScript function (erasable syntax only — no `enum`/namespaces; type annotations are advisory); call tools as `await tools.name(args)` (quoted access for exotic names); a failed tool call **rejects** with an `Error` carrying the tool's error text — catch it to handle and continue; calls run **sequentially** even under `Promise.all`; emit results via `return` and/or `console.log`, and only that curated output returns to the context — intermediate tool results never do. That last line is the payoff the whole design serves: output-side context cost becomes the model's own editorial decision. On the input side the `.d.ts` is not free — for a large tool surface it can rival the native JSON schemas it replaces (and `'both'` pays for the two side by side) — but it is prefix-stable, so provider prefix caching amortizes it; the win is workload-dependent and the RFC claims no more. + +## Plan + +Four stacked PRs, each gates-green (`typecheck`, `lint`, `test:coverage`, `test:snapshot`, `doc-sync`, `verify-module-graph`, `build`, `hygiene`) with docs updated in the same change: + +1. **This RFC revision** (docs-only): the file rewritten as above (renamed `2026-06-15-code-mode.md`, same first-proposed date), regenerated RFC index. +2. **`dsh-code-runtime`** (interface package): the group `packages/code-runtime/`, abstract `CodeRuntime`, vocabulary types, ctx-key declaration, group README + package README + catalog updates. Unit tier: HMR safety (dispose removes `ctx.codeRuntime`), contract docs. This package has no behavior to snapshot or e2e; its coverage story is unit-only by design. +3. **`dsh-code-runtime-worker`**: the implementation above. Unit tier (real workers, no mocks — they are cheap and local): output/value capture, log source attribution, error kinds (exception incl. non-erasable syntax, timeout vs abort vs worker-exit under OOM), compute-time-only timeout (a slow binding does not expire the run), binding bridge hostility cases (unknown name, duplicate id, post-settlement message), structured-clone fallback, cap truncation, `env` emptiness verified from inside the program, dispose-awaits-exit. A real-load-path test runs the built package (`lib/`) so the worker entry resolves both unbuilt (tsx) and built — the published-bin guard from [docs/testing.md](../../../testing.md). +4. **Native code mode in `dsh-tools`** + the end-to-end surface: mode config, provider switch, `tools:sdk` section, `jsonSchemaToTs`, `run_code` + dispatch bridge + serialization queue, `tool/code-dispatch` event; [docs/architecture.md](../../../architecture.md) (tool-pipeline section + `ctx.codeRuntime` service row) and the [adding-a-tool cookbook](../../../cookbook/adding-a-tool.md) cross-reference updated in the same change; an `examples/` leaf + `demo:code` script wiring the worker runtime with `mode: 'code'`; move this RFC to `implemented/`. Coverage named per tier now, per the plan-time rule: **unit** — codegen table (DSL subset, quoted names, `unknown` degradation, determinism), provider contribution per mode, `toolOrder × mode` rejection, missing-runtime/wrong-language loud failures, serialization non-overlap (a probe tool records enter/exit under `Promise.all`), abort stops the queue, binding rejection on `isError`, `CodeRunFailedError` → structured `isError`, event payloads, `deriveMessages()` ignores the event, HMR safety (mode flip via config reload removes tool + section); **e2e (with-key, self-skips)** — a real model, `mode: 'code'`, a task requiring two tool calls and curation, asserting the wire tool list was exactly `run_code` and the transcript's dispatch events; **snapshot (keyless replay)** — goldens for a `run_code` turn in `'code'` and `'both'`, pinning the SDK section text, the collapsed header tools, dispatch events, and the result card. + +The four PRs land in order (each on the previous); per stacked-review practice, review fixes land on the PR that introduced them and merge down. + +## Alternatives considered + +**An add-on consumer plugin, zero core changes (the previous draft of this RFC).** Rejected on both halves. The wire-collapse half aged out from under it: it targeted the `agent/request` waterfall, which [reconstructable requests](../../implemented/architecture/2026-07-05-reconstructable-requests.md) has since re-typed to call-config-only, and the surviving alternative — transforming the assembly a waterfall listener receives — is strictly worse than contributing the right list in the first place (transformation must undo `toolOrder` canonicalization it cannot see the config for, and its correctness depends on where it sits in a listener chain). The deeper reason is ownership: which tools the model is offered, in which representation, is the registry's single concern — `schemas()` for function calling and the SDK for Code Mode are two projections of one store, and splitting the second projection into a satellite package would preserve a boundary the domain does not have. + +**`node:vm` as the reference runtime, hardening deferred (also the previous draft).** Rejected: `node:vm` is not isolation (prototype-chain escapes reach the host realm), cannot interrupt a hot loop, and forced the draft into a two-flag unsafe ceremony plus a mandatory follow-up RFC. The worker thread delivers the missing properties now — separate isolate, empty env, `resourceLimits`, reliable `terminate()` (all verified by probe before this revision) — at bash-equivalent trust, so the reference implementation and the production one are the same package and the ceremony dissolves. + +**Result elision / summarization over native tool-calling.** Addresses only the context-bloat half of the problem: trimming old `tool-result`s (now cheap to add as a logged surface replace, per the reconstructable-requests consequences) still pays one model round-trip per call and cannot express loops, branches, or joins. Complementary, not competing; it can layer under Code Mode for residual native calls. + +**Parallel native dispatch in the loop.** The other answer to round-trip cost; still valid future work (the open TODO), still blocked on concurrency-safety metadata, and still no composition — it parallelizes calls the model already decided on in one step. Code Mode's serialized-queue decision keeps the two compatible: when the metadata lands, both native parallel dispatch and per-tool binding parallelism unlock together. + +**Always-exclusive (Cloudflare-faithful, no mode).** Rejected for this SDK's primary consumer: a coding agent's bread-and-butter single calls (`bash`, `read`, `edit`) are already ideal as native calls, and forcing every edit through a program taxes the common case. The mode config keeps the faithful form (`'code'`) one line away without imposing it. + +**Per-tool visibility tiers (this tool native, that tool code-only).** Deferred again, knowingly: it needs per-tool metadata and a presentation split that `'native' | 'code' | 'both'` does not, and every learning it depends on (how models actually split usage under `'both'`) arrives only after this ships. + +**Sanitized identifier aliases in the SDK** (`my-tool` → `my_tool`, Cloudflare's approach). Rejected: quoted keys on a `declare const` make every name reachable with zero alias-collision logic; models handle `tools["my-tool"](…)` fine. + +**A REPL-style persistent kernel** (state survives across `run_code` calls). Rejected for the MVP: cross-call state would be invisible to the session log, breaking the reconstructability guarantee that every request is a pure function of the log; fresh-per-run keeps it. A kernel-style backend remains expressible behind the seam later, with its own logging story. + +## Acceptance criteria + +- `mode: 'native'` (and unset) is byte-for-byte today's behavior: same assemblies, same headers, same snapshots. +- Under `mode: 'code'`, the assembled tool list (and thus the logged `request/header`) is exactly `[run_code]`; under `'both'`, every native schema plus `run_code`; the `tools:sdk` section is present in both, absent under `'native'`, and its text is deterministic for a fixed tool set (byte-identical across consecutive assemblies). +- The generated `.d.ts` covers every registered tool except `run_code`, non-identifier names via quoted keys, unsupported schema constructs as `unknown`, without codegen ever throwing. +- A program calling two tools returns only its curated output; each sub-call appears as a `tool/code-dispatch` event ordered by log `seq`, flows through `tools/pre-execute`/`post-execute` (a deny reaches the program as a binding rejection), and never enters derived messages. +- `Promise.all` over three bindings produces non-overlapping `ctx.tools.execute()` intervals (probe-tool assertion); aborting mid-program stops the worker and dispatches nothing further. +- Worker runtime: a hot `for(;;){}` run ends at the compute-time budget with `error.kind: 'timeout'`; a pending binding call does not consume that budget; OOM under `resourceLimits` yields `kind: 'worker-exit'` with the host process healthy; `process.env` inside a program is empty; non-erasable syntax yields `kind: 'exception'` without a worker spawn; disposal awaits worker exit. +- Misconfiguration is loud before any model request: non-native mode with no `ctx.codeRuntime`, a runtime whose `language ≠ 'typescript'`, and `toolOrder` naming a non-contributed tool all reject the assembly with actionable messages. +- The demo runs against the real API via `demo:code`; the snapshot goldens replay keylessly; all repo gates pass on every PR of the stack. + +## Risks + +**The worker is not a hard security boundary.** Deliberate and documented (§Trust posture): posture equals the existing bash tool, containment exceeds it, gating uses the same seams. Deployments needing more need a future `isolation: 'container'` backend — tracked as the seam's designed extension, not a TODO on this design. + +**`stripTypeScriptTypes` is marked experimental.** It is also what Node itself runs `.ts` files with on this repo's node floor. Mitigations: the runtime's unit suite pins the behaviors relied on (position preservation, erasable-only rejection message shape loosely), the call sits behind one private function, and `amaro`/`sucrase` are drop-in replacements if the API shifts. The erasable-only subset is a model-facing contract line, and the error path is a working feedback loop, not a dead end. + +**Prompt cost of the SDK, especially under `'both'`.** The `.d.ts` can rival the native schemas it complements; `'both'` carries two representations. Prefix stability + provider caching amortize per-session cost; the mode is per-deployment; the RFC makes no unconditional-savings claim. Measured guidance (when to prefer which mode) is explicitly post-ship learning. + +**Registry scope growth.** `dsh-tools` absorbs codegen, a tool, a bridge, and an event. Contained by module boundaries inside the package (`ts-types.ts`, `code-mode.ts` beside `schema.ts`/`json-schema.ts`/`presentation.ts`) and by the seam: everything substrate-shaped lives behind `ctx.codeRuntime`. + +**Structured-clone limits at the binding boundary.** Tool bindings pass JSON-shaped arguments and return strings in the MVP, comfortably cloneable; the seam contract states the constraint so a future binding producer cannot discover it in production. Non-text sub-result content is reduced to placeholders — a known MVP limitation, recorded in the SDK instructions. + +**Serialized-only sub-dispatch.** `Promise.all` gains no wall-clock parallelism yet, only fewer round-trips; models may over-expect. The instructions state it; lifting it is tied to the same concurrency-safety metadata the native parallel-dispatch TODO needs. + +**Timer-pause bookkeeping.** Compute-time-only budgeting adds a small state machine (pause on RPC out, resume on reply) whose bugs would misattribute time. It is unit-tested from both sides (slow binding ≠ timeout; hot loop = timeout) and is still simpler than the alternative — one budget that spuriously kills programs for waiting on a slow tool. diff --git a/docs/rfc/proposed/feature/2026-06-15-optional-code-mode.md b/docs/rfc/proposed/feature/2026-06-15-optional-code-mode.md deleted file mode 100644 index e221618ce1..0000000000 --- a/docs/rfc/proposed/feature/2026-06-15-optional-code-mode.md +++ /dev/null @@ -1,119 +0,0 @@ -# RFC: Optional Code Mode — model writes TypeScript against an SDK of all tools - -Status: proposed - -> Premise partially stale: this proposal predates [request reconstructability](../../implemented/architecture/2026-07-05-reconstructable-requests.md) — `agent/request` now shapes call config only (no request/content mutation), so the interception points named below need re-mapping onto the log channels and `system-prompt/assemble` before implementation. - -## Problem - -Today the agent loop advertises every registered tool to the model as a native JSON-schema function definition. `ToolRegistry` feeds its schemas into `ctx.systemPrompt`, the loop puts them on `GenerateOptions.tools`, and the adapter serializes them to the provider's function-calling wire format. The model then invokes one `tool-call` block per step, the loop dispatches each call through `ctx.tools.execute()` **sequentially** (parallel tool execution is an explicit open TODO in `dsh-tools` and [docs/architecture.md](../../../architecture.md)), and **every** intermediate `tool-result` re-enters the model's context on the next request. - -For multi-step tool work this is token-heavy and serial. The model cannot compose tools — loop over a result set, branch on an intermediate value, fan out, post-process — without a full model round-trip per call, and each of those round-trips drags the entire intermediate result back into context whether the model needs it or not. - -Cloudflare's [Code Mode](https://blog.cloudflare.com/code-mode/) (shipped as the `@cloudflare/codemode` npm package) proposes an alternative grounded in a simple observation: LLMs are better at writing code than at emitting tool calls, because they have seen millions of lines of real code and comparatively few contrived tool-calling traces. Instead of one tool call per step, the model writes a TypeScript program against a generated SDK that wraps all the tools, and that program is executed. The model curates what comes back — only what it `console.log`s and/or returns — instead of every intermediate result. The SDK functions are async, so the model can *express* fan-out (`Promise.all`) naturally in code; this RFC initially **serializes** those dispatches (§ Concurrency) until the tool contract grows concurrency-safety metadata, so the early win is composition and fewer round-trips, not parallelism. - -This RFC proposes an **optional** Code Mode for the DeepSeek Harness, covering **all** tools uniformly — built-in and future MCP — with no per-tool work, implemented Cordis-style with **zero core-package changes**. It fully specifies the code-execution seam and the SDK-generation pipeline, but ships only a minimal `node:vm` reference stub for execution; the hardened, sandboxed execution substrate is **deferred to a follow-up RFC** (see Risks). This RFC does not change the agent loop, and it leaves native tool-calling exactly as it is — Code Mode is a plugin you load, not a replacement. - -## Proposal - -The design follows the codebase's capability-seam pattern ([capability seams](../../implemented/architecture/2026-06-13-capability-seams.md), the `bash` template) as a three-package split, plus one consumer plugin. Nothing in `dsh-session`, `dsh-agent`, `dsh-agent-loop`, `dsh-llm`, `dsh-tools`, or `dsh-system-prompt` changes. - -**Prior art.** `@cloudflare/codemode` validates this shape directly and several of its decisions are adopted below. Its `Executor` interface is deliberately tiny — `execute(code, fns) → { result, error?, logs? }` — with a production `DynamicWorkerExecutor` (isolated Workers) and a six-line `NodeVMExecutor` example as two implementations behind it: exactly the interface/implementation split [the capability-seam pattern](../../implemented/architecture/2026-06-13-capability-seams.md) prescribes. It generates TypeScript type definitions from tools for the model's context and runs the generated JavaScript in a sandbox, capturing console output alongside the return value. It normalizes model output into an async arrow function via AST parsing (acorn) and sanitizes tool names into valid JS identifiers (`my-tool` → `my_tool`, `delete` → `delete_`). It blocks outbound network by default. The transferable lessons — minimal executor contract, host-side type derivation, capture-output-and-return-value, name sanitization, AST-normalize the code, isolate by default — are folded into the design below. What does **not** transfer is the substrate: Cloudflare's isolation is Workers-specific; our equivalent hardened substrate is the deferred follow-up. - -**Prompt-budget tradeoff (Code Mode is not unconditionally cheaper).** Deriving the SDK types host-side costs no extra *discovery* round-trip, but the generated `.d.ts` is injected into the system prompt (§3a), so the type definitions themselves **do** consume context — and for an all-tools SDK that cost scales with every registered tool and can be comparable to, or larger than, the native JSON schemas it replaces. Code Mode's saving is on the **output/result** side (the model curates what comes back; intermediate results never re-enter context) and on **round-trips** (compose many calls in one program), not on the input-side tool description. The net win is workload-dependent: it pays off for multi-call, large-intermediate-result workflows and can cost *more* for a single call against a large tool surface. The `.d.ts` section is a prefix-stable prompt prefix, so prompt caching amortizes its per-turn cost across a session; the RFC notes that caching is what keeps the injected SDK affordable, and that a deployment with a very large tool surface should weigh the SDK size against native schemas rather than assume Code Mode is strictly cheaper. - -**1. Interface package `packages/code-runtime/`** — a new package `@deepseek-ai/dsh-code-runtime` owning `ctx.codeRuntime`, depending only on `cordis`. It defines an abstract `CodeRuntime extends Service` plus the execution vocabulary. The runtime knows **nothing** about `ctx.tools`: it is handed a set of named async functions (the resolved SDK bindings), runs the program, and captures output. The result shape mirrors Cloudflare's proven-minimal contract so an error is a *field on a resolved result*, not a throw the runtime is expected to make: - -- `CodeRunRequest = { code: string; sdk: SdkBinding[]; signal?: AbortSignal }` -- `CodeRunResult = { result: unknown; logs: string[]; error?: string }` -- a readonly `safe: boolean` on the `CodeRuntime` service — `false` for an unsandboxed stub, `true` only for a real isolating substrate; consumers gate on it (§2). -- `SdkBinding = { namespace: string; fns: Record Promise> }` - -Per the "explicit > implicit at seams" convention, the request spells out every field the runtime acts on; defaulting (e.g. an output cap, a timeout derived from `signal`) is the implementation's explicit job, not a hidden `?? default` inside `run()`. The split into interface + implementation is justified under [the capability-seam pattern](../../implemented/architecture/2026-06-13-capability-seams.md) because there is **genuinely more than one planned implementation** — the node:vm stub *and* the hardened substrate (a real isolate, or the generated program run as a sandboxed process through the existing `ctx.bash` seam) that is scheduled follow-up work, not speculative optionality. The capability-seam pattern warns against splitting preemptively when only one implementation is conceivable; here a second is not just conceivable but required before any untrusted use, so the seam earns its keep. - -**Backends can differ by language/runtime, not only by trust level.** The two implementations above (unsafe stub vs. hardened substrate) differ along the *trust* axis while staying TypeScript/JS, but nothing in the `CodeRuntime` contract — a program string plus a set of named async SDK bindings in, and a `{ result, logs, error? }` out — is bound to one source language. The same seam can host backends that differ along the *language* axis, executing a program written in something other than TypeScript. Two illustrative directions: - -- **An AssemblyScript backend.** AssemblyScript is a strict TypeScript subset that compiles to WebAssembly, so a program stays familiar to a TS-fluent model while the WASM boundary supplies exactly the sandboxing the hardened substrate is meant to provide — memory isolation and no ambient host authority come from the runtime rather than from after-the-fact hardening of `node:vm`. This is an appealing route to a `safe = true` backend. -- **A Python backend.** Python is arguably the model's most native language — it has seen far more real Python than any tool-calling trace — which is the same "LLMs write better code than tool calls" argument that motivates Code Mode, taken one step further. A Python backend is itself a sub-seam over different Python *runtimes*: **CPython** (in-process or a sandboxed subprocess via `ctx.bash`) for maximum fidelity and ecosystem access, or a more controllable / embeddable interpreter — Pyodide (CPython on WASM), RustPython, or a restricted embedded interpreter — when isolation, deterministic resource limits, or a clean capability boundary matter more than running arbitrary native extensions. - -These are illustrations of the seam's reach, **not commitments** — the MVP ships only the TypeScript path. The honest caveat is that the *execution* contract is language-agnostic but the *presentation* is not: the SDK-generation pipeline below (§3a and the `jsonSchemaToTs` codegen, which emits a TypeScript `.d.ts`) is TypeScript-specific, so a non-TS backend pairs the shared `CodeRuntime` contract with its own language-appropriate SDK generator and system-prompt section (a `.pyi` stub and Python usage instructions for the Python backend, AssemblyScript-flavored types for that one). The runtime seam is reused as-is; only the codegen/prompt half is per-language. - -**2. Implementation package `packages/code-runtime-vm/`** — a new package `@deepseek-ai/dsh-code-runtime-vm`, the `node:vm` reference stub. It type-erases the model's TypeScript via the compiler's `transpileModule` (or sucrase) — the types exist only to guide the model; the runtime is plain JS — then wraps the body in an async IIFE for top-level `await` (Cloudflare's `NodeVMExecutor` does literally `new AsyncFunction("codemode", "return await (${code})()")`), runs it in a `vm.Context` whose globals are a capturing `console` and the SDK namespace objects, awaits the IIFE, and captures the return value, the buffered logs, and any thrown error (as `error: string`). It applies an **output cap** (truncate captured logs) and a **timeout tied to `request.signal`**. These caps limit blast radius; **they are not a security boundary**. node:vm is **not** isolation: withholding `require`/`process` does not contain anything (code escapes via `constructor`/prototype reflection), and per [AGENTS.md](../../../../AGENTS.md) the harness must never hand model output the ambient environment. - -**The unsafe-runtime guard is enforceable, not a README warning.** Because a README caveat is not a control — and AGENTS.md's "never hand model output ambient authority" is a hard rule, not advice — the design makes the danger refuse to run by construction. Two layers: - -- **The runtime declares its trust level.** `CodeRuntime` carries a readonly `safe: boolean` (a `node:vm`-class stub returns `safe = false`; a real isolate/sandboxed-process substrate returns `safe = true`). The `code-runtime-vm` constructor *additionally* requires an explicit opt-in — `new VmCodeRuntime({ unsafe: true })` — and **throws** if that flag is absent, so merely depending on the package and wiring it cannot silently produce a live unsafe runtime; the operator must type the word `unsafe`. -- **The consumer refuses to expose `run_code` over an unsafe runtime by default.** When `code-mode` initializes, if `ctx.codeRuntime.safe === false` it does **not** register `run_code` unless the plugin itself is configured with an explicit acknowledgement (e.g. `code-mode` config `allowUnsafeRuntime: true`). Absent that, it logs a typed error and registers nothing — so a real model never reaches an unsandboxed runtime by a single config slip. The refusal path is tested: with the acknowledgement unset and an unsafe runtime, `run_code` is absent (and the wire tool list is unchanged from native); with both opt-ins set, it registers and runs. This keeps the unsafe reference backend usable for tests and trusted local demos while making production misuse take two deliberate, greppable flags rather than one mistake. - -`code-runtime-vm` is therefore documented as **reference / test-only / unsafe-for-untrusted-input**, acceptable in the MVP only because the code runs at harness trust *and* both opt-in flags must be set. Signal handling is best-effort: it aborts in-flight sub-dispatches but cannot reliably interrupt a hot synchronous loop (`while(true){}`) in node:vm — another reason the hardened substrate is deferred, not optional-forever. - -**3. Consumer plugin `packages/code-mode/`** — a new package `@deepseek-ai/dsh-code-mode`, the plugin that wires everything together. It declares `inject = ['tools', 'systemPrompt', 'codeRuntime']` — Cordis throws on access to a service that is not injected, and keeps the plugin inactive until all three exist (the same pattern as `tool-bash`'s `inject = ['tools', 'bash']`), which also gives correct load-ordering relative to `code-runtime`/`code-runtime-vm`. The plugin contributes four things, all through existing seams: - -**3a. Tool presentation — a lazy system-prompt section (the injection seam already exists).** `dsh-system-prompt` already provides the Cordis-idiomatic way for any plugin to inject prompt snippets: `ctx.systemPrompt.section({ name, order, text })`, fiber-scoped and auto-disposed via `ctx.effect()`, where `text` may be a lazy `() => string` re-evaluated at each assembly. No new mechanism is needed or invented. Code Mode registers a lazy section (high `order` so it lands last) whose thunk reads `ctx.tools.schemas()` at assembly time and regenerates the SDK `.d.ts` plus usage instructions from the currently-registered tool set. Because the thunk reads the live registry, coverage of every tool — built-in, MCP, future — is automatic. - -**3b. Wire tool-list enforcement — an `agent/request` listener (the authoritative seam).** The goal "exactly one tool reaches the wire" must be enforced where the wire request is finalized. The loop calls `ctx.systemPrompt.assemble()` first, *then* builds `GenerateOptions` (seeding `tools` from `assembly.tools`), *then* runs the `agent/request` waterfall, *then* calls `ctx.llm.stream()`. A `system-prompt/assemble` listener can only influence the *seed*; `agent/request` is the last seam before the model call, so it is authoritative. The plugin registers an `agent/request` listener that does `const final = await next(); return { ...final, tools: [runCodeSchema] }` — overriding the value *returned by* `next()`, not the inbound argument, so it dominates the cooperative request listeners it wraps. It registers with `prepend: true` to sit at the outer edge of the waterfall chain. One honest caveat, stated in the RFC body: `ctx.llm.stream()` itself runs a further `llm/stream` waterfall before the adapter, so the guarantee is "authoritative within the agent request pipeline," not an absolute wire invariant; if a hard invariant is ever required, a defensive `llm/stream` assertion with a spy adapter covers it in tests. - -**3c. The single tool — `run_code`.** Registered normally in `ctx.tools` with one parameter `{ code: string (required) }`. Because it is an ordinary tool, the unchanged loop dispatches it through the normal path — this is the crux of "zero loop changes." Its `execute(args, exec)`: - -1. Builds the SDK bindings. For each real tool, an async `invoke(callArgs)` that **checks `exec.signal?.aborted` (throwing if set) before and after** calling `ctx.tools.execute({ callId: , name, arguments: callArgs, agent: exec.agent, signal: exec.signal })`, then maps the resulting `ContentBlock[]` to a simplified `{ output, isError }` (text blocks for the MVP), and emits an observability event. The explicit abort check matters because `ctx.tools.execute()` *catches* thrown tool errors and converts them to `isError` results — without the check, an aborted sub-call would look like ordinary error data and the program would keep running instead of stopping. Sub-dispatch still flows through the `tools/pre-execute`/`tools/post-execute` waterfalls, so permission/sandbox/hook plugins apply to code-mode calls exactly as to native ones. -2. Calls `ctx.codeRuntime.run({ code: args.code, sdk: bindings, signal: exec.signal })`. -3. Surfaces the outcome. A *successful* run returns `[{ type: 'text', text: }]`. A *runtime-error* result cannot be reported by returning content, because a normal `ToolDefinition.execute()` returns only `Promise` and `ToolRegistry.execute()` hardcodes `isError: false` on any successful return — `isError: true` arises only from the registry's catch path. So on an error result the tool **throws a `CodeRunError extends HarnessError`** (`HarnessError` is exported from `dsh-llm`; the registry catch turns any throw into `isError: true` with the message as text, and a `HarnessError` additionally carries structured `{ name, code }`). An alternative — registering `run_code` handling as a `tools/execute` listener that returns a full `ToolExecutionResult` and can set `isError` directly — is noted; the throw is simpler and preferred. - -**3d. Result discipline — what the model receives.** The model gets back **only the captured console output and/or the program's return value** (the model chooses which to surface). Intermediate sub-call results are **never** returned to the model. This is the core context-saving benefit: the agent curates its own output, exactly as a script's stdout curates a pipeline's intermediate state. - -**Sub-call CallIds.** Real tool calls dispatched from inside `run_code` need ids, but `CallId` is normally provider-issued (a branded string for correlating a call with its result — only brand-wrapped via `CallId()`, with no generator and no documented session-global-uniqueness guarantee). The plugin mints deterministic sub-ids scoped to the parent: `` `${exec.callId}:code:${n}` `` with a per-run counter `n`. These are unique within one `run_code` run (assuming the parent `callId` is unique, which the provider guarantees per turn); the `code/dispatch` event additionally carries the session log's `seq` so the UI and persistence can order and disambiguate globally without relying on the id alone. `ToolExecution.agent` is optional; the normal loop always supplies it (and with it `exec.agent.session`, the log `code/dispatch` appends to). A `run_code` execution arriving without `exec.agent` still runs (sub-calls propagate `agent: undefined`, exactly as the loop's own contract allows) but **skips session-log observability** — with no session to append to, those direct runs are simply not logged. - -**Observability without context cost.** Each sub-dispatch emits a session event **declared by the `dsh-code-mode` plugin itself** via `SessionEventMap` declaration merging (the map is merge-extensible precisely so plugins can add events without touching `dsh-session`). Shape: `code/dispatch` with `{ parentCallId, subCallId, name, arguments (or redacted), isError, summary }`, ordered by the session log's own `seq`. `deriveMessages()` does **not** translate it into a model message — an unknown event type falls through its `default`, per the merge-extensible-union convention — so the UI and persistence ([session persistence](../../implemented/architecture/2026-06-14-session-persistence.md)) can render every sub-call while the model's context only ever receives the single `run_code` tool-result. Because the event lives in the plugin, this adds no core change. - -**SDK codegen.** A pure `jsonSchemaToTs(schema)` in `code-mode` maps the JSON-schema subset the `defineTool` DSL produces (object/string/number/boolean/array, `properties`, `required[]`, `enum` → string-literal union, nested objects, array `items`) to a TS type literal. It is **total**: any unsupported construct (`$ref`, `oneOf`/`anyOf`, `integer`, `null`, `additionalProperties`, or any raw MCP shape it does not recognize) degrades to `unknown` without throwing — it never crashes codegen. Typing is best-effort, not a guarantee, because MCP tools accept arbitrary JSON Schema and `ToolSchema.parameters` is typed only as `Record`. Because `ToolSchema.name` is an arbitrary string (not necessarily a valid TS identifier), the SDK is generated as a **namespace with quoted access** (e.g. `tools["some-mcp-tool"](args)`) plus safe camelCase aliases where the name is a clean identifier; alias collisions and TS reserved words fall back to quoted-only access (no duplicate alias emitted). This mirrors Cloudflare's `sanitizeToolName`. `run_code` itself is filtered out of the SDK. The MVP surfaces text content only; image and other block types in sub-results are deferred (noted as a limitation). - -**Concurrency — serialized by default (the binding must enforce it).** The SDK functions are async, so a model writing `await Promise.all([tools.a(...), tools.b(...)])` would *start both* immediately, and each would call `ctx.tools.execute` right away — i.e. the binding shape makes concurrent dispatch the **default**, not an opt-in. Because the tool contract carries **no concurrency-safety metadata today** (parallel tool execution and a concurrency-safety hint are an open TODO in both `dsh-tools` and [docs/architecture.md](../../../architecture.md): "phase 1 executes tool calls sequentially"), concurrent dispatch through a not-yet-hardened tool may race. So a prose "may serialize" is not sufficient. **Decision: the MVP SDK bindings enforce serialization** — each `run_code` invocation owns a per-run dispatch queue, and every `invoke()` chains onto it (`tail = tail.then(() => ctx.tools.execute(...))`), so even `Promise.all` over SDK calls executes them one at a time in submission order. This is a hard acceptance criterion, with a test that issues `Promise.all([...])` from a program and asserts the underlying `ctx.tools.execute` calls did **not** overlap (e.g. a probe tool records enter/exit and the test asserts no interleaving). The `.d.ts` may *describe* the model-visible functions as async (they are), but the implementation guarantees serial execution. Lifting serialization is deferred: only once a tool can declare itself read-only / concurrency-safe does the binding allow those specific tools to overlap. The same per-run queue is where the before/after abort checks (§3c) live, so an aborted run drains no further queued dispatches. - -**Tool visibility tiers (design intentionally skipped).** A natural extension is to mark each tool with a *visibility tier*: some tools "direct-call eligible" (still offered as native wire tools alongside `run_code`), some "code-mode only" (reachable solely from within a `run_code` program, never on the wire), and the default "both." This would let a deployment keep a few high-frequency or approval-gated tools as direct calls while routing the long tail through Code Mode, or hide composition-only primitives from the native surface entirely. This RFC notes the possibility but **intentionally skips the detailed design** — the per-tool metadata, how it interacts with the `agent/request` enforcement in 3b, and the presentation split in 3a are left to a follow-up. The MVP is the simple two-state model: Code Mode on (everything via `run_code`) or off (everything native). - -**Optionality / toggle.** Loading the `code-mode` plugin enables Code Mode for that context; not loading it leaves today's native tool-calling untouched. The two are mutually exclusive within one ctx, because Code Mode rewrites the wire tool list down to `[run_code]`. Per-agent selection via ctx forks, and the visibility tiers above, are future work; the MVP toggle is plugin presence. - -## Alternatives considered - -**Result elision / summarization over native tool-calling (the narrower route).** The Problem has two halves — context bloat (every intermediate `tool-result` re-enters context) and serial composition (one tool call per round-trip). The context-bloat half can be addressed *without* any code-execution runtime: keep provider tool-calling exactly as it is, and add a plugin on the `agent/request` waterfall (or a compaction pass akin to [the session-persistence work](../../implemented/architecture/2026-06-14-session-persistence.md)) that elides or summarizes older `tool-result` blocks before they re-enter the model's context — drop them past a window, replace large payloads with a digest, or keep only the blocks the model still references. This is strictly less invasive than Code Mode: no new runtime seam, no model-written programs, no new safety surface. It is the right tool if context growth is the only pain. - -It is insufficient for the **composition / round-trip** half, which is the decisive reason this RFC does not stop there. Elision still pays one model round-trip per tool call: a loop over N items is N turns, a branch on an intermediate value is a turn to fetch then a turn to act, and post-processing (filter, join, reduce) either happens in the model's head over full payloads or not at all. Code Mode collapses all of that into one program — the loop, the branch, the join run in the runtime, and only the curated result returns. Elision also cannot express fan-out or data-dependent control flow; it only shrinks what comes back. So the two are complementary, not competing: elision could even layer *under* Code Mode for the residual native-tool paths. The RFC chooses Code Mode because the round-trip/composition cost is the larger structural limit, and accepts the new code-execution surface as the price — which is exactly why the execution substrate is gated behind the enforceable safety guard (§2) and the hardened backend is a hard prerequisite for untrusted use. - -**Why not change the loop to dispatch native tool calls in parallel instead?** That is the other obvious answer to the round-trip cost, and it remains valid future work (it is the open `dsh-tools`/architecture.md TODO). But it is a core-loop change requiring the same concurrency-safety metadata Code Mode defers, and it still does not give the model *composition* (branch/loop/post-process between calls) — only parallelism of independent calls the model already decided to make in one step. Code Mode delivers composition with zero core change; parallel native dispatch and Code Mode can coexist later. - -## Plan - -1. Scaffold the interface package `packages/code-runtime/` per [the cookbook](../../../cookbook/adding-a-package.md): abstract `CodeRuntime extends Service` (`super(ctx, 'codeRuntime')`) with a readonly `safe: boolean`, the `declare module 'cordis'` ctx key, the `CodeRunRequest`/`CodeRunResult`/`SdkBinding` vocabulary, method contracts documented in JSDoc (what `run` captures, abort semantics, that an error is a result field not a throw, what `safe` means). HMR-safety test (dispose the contributing fiber, assert `ctx.codeRuntime` is gone). -2. Scaffold the implementation package `packages/code-runtime-vm/`: the node:vm stub — `safe = false`, a constructor that **throws unless given `{ unsafe: true }`**, transpile/type-erase, async-IIFE wrap, capturing `console`, SDK globals, return-value/logs/error capture, output cap, signal-tied timeout. Tests for output capture, return value, error-as-field, abort, the constructor refusal without `unsafe`, and a README documenting the "not a sandbox, trusted-only" caveat prominently. -3. Scaffold the consumer plugin `packages/code-mode/`: `jsonSchemaToTs` codegen with namespace/quoted-access + alias handling (unit tests, including non-identifier MCP names and unsupported-shape → `unknown`); the registered lazy `ctx.systemPrompt.section()` carrying the SDK `.d.ts`; the `agent/request` listener (`prepend: true`) collapsing `request.tools` to `[run_code]` after `await next()`; the **unsafe-runtime gate** (refuse to register `run_code` when `ctx.codeRuntime.safe === false` unless `allowUnsafeRuntime` is set); the `run_code` tool with the dispatch bridge (per-run serialization queue, deterministic sub-call ids, before/after abort checks, `CodeRunError` on error results); and the `code/dispatch` event declared here via `SessionEventMap` merge. Declare `inject = ['tools', 'systemPrompt', 'codeRuntime']`. -4. Tests: HMR-safety (dispose removes the tool, the section, and the listener); a waterfall test that the wire tool list is exactly `[run_code]` (spy adapter, asserting via `agent/request` and optionally `llm/stream`); an integration test that a program calling two tools returns only its printed/returned output (verify the world, not the self-report); a **serialization test** that `Promise.all([...])` over SDK calls does not overlap the underlying `ctx.tools.execute` invocations (a probe tool records enter/exit; assert no interleaving); `deriveMessages()` ignores `code/dispatch`; abort mid-program stops further dispatches; `CodeRunError` surfaces as `isError: true`; and the **unsafe-runtime refusal test** (§3, the VM-guard): with the unsafe flag unset, a non-mock agent's `run_code` is refused; with it set, the program runs. -5. Wire an example: `examples/coding-agent-code-mode` (or a config flag on the existing example) loading the trio. Running it against the node:vm stub requires both opt-ins (`VmCodeRuntime({ unsafe: true })` and `code-mode`'s `allowUnsafeRuntime`); the example sets them explicitly and comments why, or uses a mock model — a real model never reaches the unsandboxed stub without those deliberate flags. Add a `pnpm run demo:*` entry. -6. Docs: update [docs/architecture.md](../../../architecture.md) (a `ctx.codeRuntime` row in the service map, a Code Mode note under the tool pipeline / capability seams sections); add a [cookbook](../../../cookbook) note on writing a `CodeRuntime` backend; and **file the follow-up RFC for the hardened execution substrate** (the isolate/sandboxed-process design, the additional-language backends sketched in §1 — AssemblyScript/WASM, Python — with their per-language SDK generators, plus the tool-visibility-tier design skipped here). On landing, move this file to `implemented/` and update its row in [the RFC index](../../README.md). - -## Acceptance criteria - -- The three packages exist and pass their suites: `dsh-code-runtime` (the abstract seam), `dsh-code-runtime-vm` (the reference stub whose constructor throws without `{ unsafe: true }`), and `dsh-code-mode` (SDK codegen, the lazy prompt section, the `agent/request` collapse, the `run_code` tool). -- The wire tool list is exactly `[run_code]` under the plugin (spy-adapter test); the generated SDK covers every registered tool, with non-identifier names reachable via quoted access. -- A program calling two tools returns only its curated output; `code/dispatch` events land in the session log and never enter derived history. -- `Promise.all` over SDK calls does not overlap the underlying `ctx.tools.execute` invocations (the per-run serialization queue holds); an abort stops further dispatches. -- With `allowUnsafeRuntime` unset over an unsafe runtime, `run_code` is not registered and the wire tool list is unchanged from native. - -## Risks - -node:vm is not a sandbox. This is the single biggest caveat. Withholding `require`/`process` is not a boundary; the MVP runs at harness trust only; the hardened substrate is a hard prerequisite before any untrusted use and is the explicit subject of a follow-up RFC. The guard is enforceable, not just documented: the runtime exposes `safe: boolean`, the VM stub throws unless constructed with `{ unsafe: true }`, and `code-mode` refuses to register `run_code` over an unsafe runtime unless separately acknowledged (`allowUnsafeRuntime`) — production misuse requires two deliberate, greppable flags, and the refusal path is tested. - -Wrong seam would leak tools. If the wire tool list were enforced only in `system-prompt/assemble`, a later `agent/request` listener could re-add tools. Mitigation: enforce `request.tools = [run_code]` in the `agent/request` waterfall (the authoritative seam, run last before `llm.stream()`) with `prepend: true`, and assert exactly one wire tool in tests. The residual `llm/stream` caveat is documented, not hidden. - -Concurrency before the contract supports it. The binding shape makes concurrent dispatch the default, and the tool contract has no concurrency-safety metadata yet, so unguarded `Promise.all` over SDK calls could race a not-yet-hardened tool. Mitigation: the MVP bindings enforce a per-run serialization queue (every `invoke` chains onto the previous), with a test asserting `Promise.all` from a program does not overlap the underlying `ctx.tools.execute` calls. Per-tool parallelism is unlocked only once a tool can declare itself concurrency-safe. - -Two presentation modes to keep coherent. A tool added later must work in both native and Code Mode. Mitigation: both the codegen thunk and the `agent/request` listener read `ctx.tools.schemas()`, so coverage is automatic; a test asserts every registered schema produces valid `.d.ts`, including non-identifier MCP names via quoted access. - -Type-erased runtime is not type-checked. The model can write code that type-checks against the advisory `.d.ts` but throws at runtime, and MCP-schema typing is best-effort. Mitigation: errors are captured as `CodeRunResult.error` and surfaced so the model can self-correct; the `.d.ts` is explicitly advisory. - -Lost observability of sub-calls. Routing everything through one `run_code` result hides the individual calls from the model — and could hide them from operators too. Mitigation: the plugin-declared `code/dispatch` event keeps every sub-call in the session log and UI without polluting model context. - -Abort granularity. node:vm cannot reliably interrupt hot synchronous code, and `ctx.tools.execute()` converts thrown aborts into `isError` data. Mitigation: the SDK bindings check `signal.aborted` and throw before/after each dispatch so an aborted sub-call stops the program; the vm stub wraps the run in a signal-tied timeout; the hardened substrate addresses the hot-loop case. - -Unsafe example wiring. A demo running a real model through the node:vm stub would hand model output ambient authority. Mitigation: examples are mock-model or explicitly marked unsafe; `code-runtime-vm` is labeled reference/test-only. - -Non-text sub-results dropped in the MVP. Image and other block types from sub-calls are not surfaced into the program yet. Mitigation: noted as a known limitation; block-type handling deferred.

The seam itself keeps the wider structured-clone contract (it is about the port, and stated so a future binding producer cannot discover it in production); consumers with stricter payload needs enforce them at their own boundary, as the bridge does.

That shape is simple and transport-neutral, but it makes slow delegation expensive for the parent. A model that wants two independent investigations must either run them serially or hold the parent step open for the entire child duration. + +The harness already has one background-task precedent in bash. Bash has task ids, owner-token checks, output polling, stop, completion notifications, and prompt guidance. Subagents need the same user-facing habit, but not by copying bash's process-output semantics: a subagent does not expose an incremental stdout stream, and its child session remains the home for internal steps. The parent needs to start a child, keep working, later wait for or read the final answer, and stop the task when it is no longer relevant. + +The design also has two lifecycle constraints that the synchronous cut does not face. First, a background subagent can outlive the tool call that started it, so the tool-call abort signal must not stay wired to the child after the id is returned. Second, a completion notice can only be injected into a live owner agent: once an ACP session closes or an agent handle is disposed, `agent.inject()` cannot append to that session. The feature must therefore define whether background subagents survive owner disposal. + +## Proposal + +Add a background mode to the existing model-facing subagent tools and add three companion tools: `subagent_wait`, `subagent_output`, and `subagent_stop`. The background task registry lives in `@deepseek-ai/dsh-subagent`, keyed by branded task ids and owner tokens, while `@deepseek-ai/dsh-tool-subagent` owns the model-facing schemas, text rendering, completion notice injection, and prompt guidance. + +`dsh-tool-subagent` becomes a single multi-tool consumer plugin instead of one plugin instance per provider. Its config maps model-facing tool names to provider names, so one plugin instance can register `subagent`, `subagent_fork`, and any deployment-specific aliases such as `subagent_acp`, plus the shared background control tools. Providers remain named implementations on `ctx.subagents`: `spawn`, `fork`, `acp`, or future backends. This keeps provider implementation and model-facing exposure separate while avoiding a failure mode where one `subagent` tool exposes `run_in_background` but the companion wait/output/stop tools were never loaded. + +The background task is scoped to the owner session, not durable across session closure. A background subagent starts only from a model-driven call with `exec.agent`; the service stores the caller's `session.header.id` as the owner token. `subagent_output`, `subagent_wait`, and `subagent_stop` compare that stored token with the caller's session id and reject cross-session access. When the owner agent is disposed, the service cancels any running background subagent tasks for that owner and discards their retained snapshots after quiescence. Completion notices are best-effort: if the owner agent is still registered, `dsh-tool-subagent` injects a short `context/message`; if the owner is gone, no notice is written. + +## Tool surface + +Each configured delegation tool may expose `run_in_background?: boolean`. The deployment can disable background mode per tool; a disabled tool does not include the parameter in its schema. A foreground call keeps the synchronous semantics: it waits for `run.result`, returns final text on `completed`, maps non-clean terminal stop reasons to an errored tool result, and disposes the run in `finally`. + +A background call validates that a parent agent exists, starts the provider run through `ctx.subagents`, registers a task, and returns `started background subagent task `. It checks an already-aborted tool signal before starting, but after the id is returned it does not keep the tool-call signal connected to `run.cancel()`. The parent step may finish while the child continues. + +`subagent_output` is a non-blocking status read for a background subagent task. While the task is `running` or `stopping`, it returns only a status line. Once terminal, it returns the final text output or error message plus the terminal status. Reading output is idempotent and does not consume the result; v1 deliberately exposes no incremental transcript cursor because the child session remains the detailed trace. + +`subagent_wait` waits for a task to become terminal, bounded by a defaulted and capped timeout from `dsh-tool-subagent` config. A wait timeout returns `running` and leaves the child alive. Aborting the wait call cancels only the wait, not the background task. + +`subagent_stop` requests cancellation of a running or stopping task and returns immediately. The task registry remains responsible for observing the run settle, recording the terminal state, and disposing the run. Calling stop on an already-terminal task reports that terminal state rather than failing. + +## Runtime task model + +`@deepseek-ai/dsh-subagent` adds a runtime-global task registry to `SubagentService`. Task ids and owner tokens are branded types. A task snapshot records the task id, provider name, child run id, owner token, status, started/finished timestamps, final output, and error message. The status vocabulary is `running`, `stopping`, and the existing terminal `SubagentStopReason` values (`completed`, `aborted`, `error`, `max-tokens`, `refusal`, plus merge-extensible provider values). + +The registry owns task settlement. It attaches one continuation to `run.result`; on success it stores the final output and stop reason, on rejection it stores `error`, and in both cases it disposes the run and notifies task-done listeners. Listener failures are contained and logged so one consumer cannot starve cleanup. + +The registry is runtime-global because `ctx.subagents` is a service shared by all live agents in the Cordis context. Session isolation is therefore explicit owner-token authorization, not an assumption about separate service instances. This mirrors the bash background-task fence: predictable ids are safe only when read/stop operations check the caller's owner token. + +Owner disposal is a hard lifecycle boundary. `SubagentService` listens to `agent/disposed`, finds tasks owned by that agent's session id, and cancels running tasks. It does not attempt to persist unfinished task state, resume children, or inject into disposed sessions. A future durable job system can extend this boundary, but this feature intentionally keeps background subagents tied to live sessions. + +## Model guidance + +`dsh-tool-subagent` registers a system-prompt section that teaches the background-task habit: + +- Keep track of every task id returned by a background subagent call. +- Do not produce a final answer while a relevant background subagent is still running. +- While waiting, continue independent exploration or use other tools when useful. +- Before summarizing or handing work back, call `subagent_wait` or `subagent_output` to collect finished tasks. +- Call `subagent_stop` for a background task that is no longer needed. +- End without collecting a task only when its result is irrelevant or the task was explicitly stopped. + +This prompt guidance is not the enforcement boundary.

Background subagents should not block on that extraction because subagents have a narrower result model than bash: no incremental stdout, no spill files, and no process exit markers. The implementation should keep the subagent registry small and shaped so it can later migrate into a generic runtime without changing the model-facing `run_in_background`, `subagent_wait`, `subagent_output`, and `subagent_stop` contract. + +## Alternatives considered + +### Why not keep one `dsh-tool-subagent` instance per provider? + +The existing one-instance-per-provider shape makes aliasing simple, but companion tools become ambiguous.

Listener `this` stays `base`-shaped. `{ global: true }` listeners bypass filtering (Cordis semantics). +- `Scoped` The compile-time carrier brand: scope-filtered events demand it as their `this` type, so dispatching with a bare subject is a compile error. +- `isScopeCarrier(value)` / `carrierKeyOf(value)` Runtime carrier marks, used by the dev invariants to assert every scope-filtered dispatch carries a carrier keyed to the subject its arguments name. + +## Design contract + +Ownership and visibility derive from ONE fact — which context a registration went through. An explicit `{ scope }` registration parameter could express "visible to X, disposed with Y", which is almost always a bug; the scoped context makes it unrepresentable.

Thu, 9 Jul 2026 01:09:21 +0800 Subject: [PATCH 046/311] feat(core): scope-aware registries and session dispatch carriers dsh-tools and dsh-system-prompt gain a per-scope registration layer over dsh-scope: a registration through a scoped context files into that scope, shadows a same-named global contribution for that scope (per-agent persona and tool variants), and unwinds with the scope. tools.restrict() masks the global surface per scope (snapshot-at-registration, loud unknown-name validation, intersection composition; scoped grants bypass). One visibility function feeds schemas/get/execute, so prompt, presentation, and dispatch can never disagree; out-of-view executes as UNKNOWN_TOOL. Prompt tool providers now receive the AssembleContext and return {schemas, knownNames}: toolOrder validates against the pre-restriction name universe (a typo fails every assembly loudly) while ordering operates on the post-restriction schemas (a restricted-away tool is a normal absence). dsh-session captures each session's dispatch carrier at enter() from the entering context's scope tag, and the new sessions.flush(session) owns the awaited session/flush dispatch. tools/pre|post-execute and system-prompt/assemble dispatch with scope carriers keyed by their subject; session/created|event|flush by the owning session's scope. --- .../core/agent-loop/tests/tool-order.spec.ts | 2 +- packages/core/session/package.json | 2 + packages/core/session/src/index.ts | 78 +++++- packages/core/session/tests/scoped.spec.ts | 112 ++++++++ packages/core/session/tsconfig.json | 3 + packages/core/system-prompt/package.json | 2 + packages/core/system-prompt/src/index.ts | 246 +++++++++++++----- .../core/system-prompt/tests/scoped.spec.ts | 138 ++++++++++ .../system-prompt/tests/system-prompt.spec.ts | 16 +- .../system-prompt/tests/tool-order.spec.ts | 26 +- packages/core/system-prompt/tsconfig.json | 3 + packages/core/tools/package.json | 2 + packages/core/tools/src/index.ts | 237 +++++++++++++++-- packages/core/tools/tests/scoped.spec.ts | 172 ++++++++++++ packages/core/tools/tsconfig.json | 3 + pnpm-lock.yaml | 15 ++ 16 files changed, 940 insertions(+), 117 deletions(-) create mode 100644 packages/core/session/tests/scoped.spec.ts create mode 100644 packages/core/system-prompt/tests/scoped.spec.ts create mode 100644 packages/core/tools/tests/scoped.spec.ts diff --git a/packages/core/agent-loop/tests/tool-order.spec.ts b/packages/core/agent-loop/tests/tool-order.spec.ts index 35329ce679..d9b0a87e1d 100644 --- a/packages/core/agent-loop/tests/tool-order.spec.ts +++ b/packages/core/agent-loop/tests/tool-order.spec.ts @@ -107,7 +107,7 @@ describe('loop-level canonical tool order', () => { agent.send([{ type: 'text', text: 'go' }]) await waitForIdle(ctx, agent) expect(adapter.requests).toHaveLength(0) - expect(errors.map(e => e.message)).toEqual(['toolOrder lists unregistered tool "ghost"; registered tools: alpha']) + expect(errors.map(e => e.message)).toEqual(['toolOrder lists unregistered tool "ghost"; known tools: alpha']) expect(foldRequestHeader(agent.session.events)).toBeUndefined() const end = agent.session.events.find(e => e.type === 'turn/end') expect(end?.type === 'turn/end' && end.data.reason).toMatchObject({ kind: 'error', step: 1 }) diff --git a/packages/core/session/package.json b/packages/core/session/package.json index 8c6645e37e..454a0d7cc3 100644 --- a/packages/core/session/package.json +++ b/packages/core/session/package.json @@ -24,11 +24,13 @@ "peerDependencies": { "@deepseek-ai/dsh-brand": "^0.0.1", "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-scope": "^0.0.1", "cordis": "^4.0.0-rc.6" }, "devDependencies": { "@deepseek-ai/dsh-brand": "workspace:^", "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-scope": "workspace:^", "cordis": "^4.0.0-rc.6" } } diff --git a/packages/core/session/src/index.ts b/packages/core/session/src/index.ts index cd9e1828b2..0bbd957a79 100644 --- a/packages/core/session/src/index.ts +++ b/packages/core/session/src/index.ts @@ -9,6 +9,8 @@ import { Context, Service } from 'cordis' import { isAbsolute } from 'node:path' import { deepFreeze } from '@deepseek-ai/dsh-llm' +import { scopeOf, scopeTarget } from '@deepseek-ai/dsh-scope' +import type { Scoped } from '@deepseek-ai/dsh-scope' import type { ContentBlock, Message, MessageSource } from '@deepseek-ai/dsh-llm' import { SESSION_FORMAT_VERSION, SessionId } from './types.ts' import type { CreateSessionOptions, EpochHeader, SessionEvent, SessionEventMap, SessionEventType, SessionHeader, SurfaceIntent, SurfaceEventType } from './types.ts' @@ -33,28 +35,48 @@ declare module 'cordis' { interface Events { /** * A session was created in the store. + * Scope-filtered dispatch (`@deepseek-ai/dsh-scope`): the carrier is the + * session's owner scope, captured when the session was ENTERED (an agent's + * session is entered through `agent.ctx`, so its events dispatch in that + * agent's scope; a bare `sessions.create()` from a plain plugin dispatches + * subject-less).

charset=UTF-8 Content-Transfer-Encoding: 8bit Every live agent owns a dsh-scope context (Agent.ctx, key = the agent), minted inside the loop's composite lifecycle effect: registrations through it are agent-visible and agent-lifetime, and agent.ctx listeners hear only that agent's dispatches. The composite yields the scope's raw disposer first (identity-nested, no un-nested window), then session entry (scoped enter captures the session carrier), then registration; teardown runs stop/drain -> unregister -> detach session -> unwind scope, keeping store/registry rollback synchronous on every failure path. CreateAgentOptions.setup(agentCtx) runs after the scope is minted and the agent registered, before agent/session-start and the loop start — the slot where a creator composes the agent's scoped world (persona sections, restrict(), scoped tools); a throwing setup unwinds inside the rollback boundary. Setup registers, it never drives. agentEvents(ctx, agent) fuses the scope carrier with the injected subject argument for every agent/* dispatch (the correct dispatch is the shortest spelling); assembleContextFor(agent) pairs the agent DX field with the scope layer selector.

This is where compaction belongs: it mutates the session surface in place (shadowing an older range with a summary node) with its log-only `compact/*` records cleanly outside any step, and the single subsequent derive reflects the mutation — so there is no double-derive and no listener can see (or be expected to act on) an assembled `messages` array that does not exist yet. -Serial (awaited in registration order), not a waterfall: a listener mutates the surface as a side effect; there is nothing to transform, but the loop must wait for the mutation to complete before opening the step and deriving.

producer/consumer matrix reads dispatch sites statically; the fused agentEvents dispatcher, the agent's loopCtx handle, the session store's captured emitCtx, and carrier-first argument lists were invisible to it, silently dropping agent-loop/session as producers of every scoped event.

A parent-scope teardown effect links each child to its parent through the memoized handle, so a disposed parent reaches its whole subtree even if the delegating tool's finally never runs; subagent/start|end dispatch in the delegating parent's scope. structured.ts loses the placeholder schema, the final-assembly swap/strip, the refcounted root runtime, and the WeakMap state: each child registers its OWN capture tool (real schema), instruction section, and enforcement listeners on child.ctx, riding the child's fiber. The commit listener is call-keyed (a stale stage from a short-circuited post-execute chain is dropped, never promoted on a later call), and one scoped prepend re-assert listener preserves the final-assembly guarantee against a stripping global listener. tool-subagent gains persona/toolFilter/maxDepth passthrough config — deny-listing the delegation tool (or maxDepth) is how a deployment bounds recursion; the omitted-toolFilter schema key is forced absent (a materialized {} would mean an empty allow-list, i.e. deny-everything). --- packages/subagent/subagent-acp/src/index.ts | 2 +- .../subagent-acp/tests/subagent-acp.spec.ts | 2 +- packages/subagent/subagent-fork/src/index.ts | 6 +- .../subagent-fork/tests/subagent-fork.spec.ts | 4 +- .../subagent/subagent-inprocess/src/index.ts | 73 +++- .../subagent-inprocess/src/structured.ts | 400 ++++++------------ .../tests/structured.spec.ts | 206 ++------- packages/subagent/subagent-spawn/src/index.ts | 11 +- .../tests/subagent-spawn.spec.ts | 65 ++- packages/subagent/subagent/src/index.ts | 24 +- packages/subagent/subagent/src/types.ts | 15 +- .../subagent/subagent/tests/service.spec.ts | 4 +- packages/subagent/tool-subagent/src/index.ts | 44 +- .../tool-subagent/tests/tool-subagent.spec.ts | 14 +- packages/support/subagent-mock/src/index.ts | 3 +- 15 files changed, 398 insertions(+), 475 deletions(-) diff --git a/packages/subagent/subagent-acp/src/index.ts b/packages/subagent/subagent-acp/src/index.ts index b2ddd9ab2d..dd0aeb5aea 100644 --- a/packages/subagent/subagent-acp/src/index.ts +++ b/packages/subagent/subagent-acp/src/index.ts @@ -89,7 +89,7 @@ type ResolvedConfig = Required> & Pick * a request needing any of them before `start` runs). */ class AcpProvider implements SubagentProvider { - readonly capabilities: SubagentCapabilities = { outputSchema: false, depthLimit: false, toolFilter: false } + readonly capabilities: SubagentCapabilities = { outputSchema: false, depthLimit: false, toolFilter: false, persona: false } // Context contract: an out-of-process ACP child starts fresh — no parent conversation crosses the process boundary. readonly inheritsParentContext = false diff --git a/packages/subagent/subagent-acp/tests/subagent-acp.spec.ts b/packages/subagent/subagent-acp/tests/subagent-acp.spec.ts index 3eb12fac38..6bf3413485 100644 --- a/packages/subagent/subagent-acp/tests/subagent-acp.spec.ts +++ b/packages/subagent/subagent-acp/tests/subagent-acp.spec.ts @@ -530,7 +530,7 @@ describe('dsh-subagent-acp', () => { it('advertises no start-time capabilities (out-of-process child)', async () => { const ctx = await setup() const provider = ctx.subagents.getProvider('acp')! - expect(provider.capabilities).toEqual({ outputSchema: false, depthLimit: false, toolFilter: false }) + expect(provider.capabilities).toEqual({ outputSchema: false, depthLimit: false, toolFilter: false, persona: false }) }) it('unregisters the provider when its fiber is disposed (HMR safety)', async () => { diff --git a/packages/subagent/subagent-fork/src/index.ts b/packages/subagent/subagent-fork/src/index.ts index d8c77a03ac..de650fa4cd 100644 --- a/packages/subagent/subagent-fork/src/index.ts +++ b/packages/subagent/subagent-fork/src/index.ts @@ -64,11 +64,11 @@ export function completedTurnPrefix(parent: Agent): SessionEvent[] { /** * The fork provider.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three dev-mode invariants close the leak-by-default regression class at runtime: (1) every scope-filtered event family must dispatch with a scope carrier — a bare dispatch throws at the call site naming the carrier rule; (2) where the subject is recoverable from the arguments (agent/*, the tool pipeline, prompt assembly) the carrier's key must BE that subject, and an assembly context must never carry agent without scope (use assembleContextFor); (3) a turn/start logged before the owning agent's agent/session-start is the setup-drives teaching error (setup registers the scoped world, it never drives the agent). --- packages/support/invariants/package.json | 6 ++ packages/support/invariants/src/index.ts | 90 ++++++++++++++++ .../invariants/tests/invariants.spec.ts | 100 ++++++++++++++---- packages/support/invariants/tsconfig.json | 9 ++ pnpm-lock.yaml | 9 ++ 5 files changed, 196 insertions(+), 18 deletions(-) diff --git a/packages/support/invariants/package.json b/packages/support/invariants/package.json index 97d6160b03..4ea36f66de 100644 --- a/packages/support/invariants/package.json +++ b/packages/support/invariants/package.json @@ -24,13 +24,19 @@ "peerDependencies": { "@deepseek-ai/dsh-agent": "^0.0.1", "@deepseek-ai/dsh-llm": "^0.0.1", + "@deepseek-ai/dsh-scope": "^0.0.1", "@deepseek-ai/dsh-session": "^0.0.1", + "@deepseek-ai/dsh-system-prompt": "^0.0.1", + "@deepseek-ai/dsh-tools": "^0.0.1", "cordis": "^4.0.0-rc.6" }, "devDependencies": { "@deepseek-ai/dsh-agent": "workspace:^", "@deepseek-ai/dsh-llm": "workspace:^", + "@deepseek-ai/dsh-scope": "workspace:^", "@deepseek-ai/dsh-session": "workspace:^", + "@deepseek-ai/dsh-system-prompt": "workspace:^", + "@deepseek-ai/dsh-tools": "workspace:^", "cordis": "^4.0.0-rc.6" } } diff --git a/packages/support/invariants/src/index.ts b/packages/support/invariants/src/index.ts index f35fbafa1d..d4b772b317 100644 --- a/packages/support/invariants/src/index.ts +++ b/packages/support/invariants/src/index.ts @@ -20,6 +20,9 @@ */ import type { Context } from 'cordis' +import { carrierKeyOf, isScopeCarrier } from '@deepseek-ai/dsh-scope' +import type { AssembleContext } from '@deepseek-ai/dsh-system-prompt' +import type { ToolExecution } from '@deepseek-ai/dsh-tools' import { HarnessError } from '@deepseek-ai/dsh-llm' import type { CallId, GenerateOptions } from '@deepseek-ai/dsh-llm' import type { Agent, AgentStatus } from '@deepseek-ai/dsh-agent' @@ -362,6 +365,93 @@ export function apply(ctx: Context, config: Config = {}): void { lastStatus.set(agent, status) }) + // --- Scoped-dispatch invariants (the agent-scoping seam) --------------- + // + // Every scope-filtered event family must dispatch with a scope carrier + // (scopeTarget) whose key IS the subject the event's arguments name — + // a dispatch without one silently reverts that event to global delivery + // (agent-scoped listeners over-hear foreign agents), and a mis-keyed one + // delivers to the wrong agent's listeners. `internal/dispatch` fires + // synchronously before listener delivery, so a violation throws at the + // dispatching call site.

The ACP ToolPresenter resolves presentations through the session agent's view (tools.get(name, agent)) so a scoped/shadowed tool renders with the same definition that executed. verify-scoped-dispatch (doc-sync + pre-push) pins the dev-invariants carrier table against the declaration JSDoc set: an event enforced but undocumented, documented but unenforced, or a registry-subject notification leaking into the table fails the build. subagent/start|end docs gain their scoped-dispatch sentence (a real gap the gate caught on first run). --- docs/cordis-catalog/events.md | 8 +-- docs/cordis-catalog/services.md | 2 +- docs/event-producer-consumer.md | 4 +- package.json | 3 +- packages/core/scope/src/index.ts | 56 ++++++++++++++++++ packages/core/scope/tests/scope.spec.ts | 23 +++++++- packages/subagent/subagent/src/index.ts | 8 +++ packages/ui/acp/src/index.ts | 20 +++++-- scripts/run-gates.ts | 1 + scripts/verify-scoped-dispatch.ts | 78 +++++++++++++++++++++++++ 10 files changed, 188 insertions(+), 15 deletions(-) create mode 100644 scripts/verify-scoped-dispatch.ts diff --git a/docs/cordis-catalog/events.md b/docs/cordis-catalog/events.md index c748f30690..798b38b02f 100644 --- a/docs/cordis-catalog/events.md +++ b/docs/cordis-catalog/events.md @@ -237,13 +237,13 @@ Source: [`packages/core/session/src/index.ts:79`](../../packages/core/session/sr ### `subagent/end` — emit -A subagent run settled — emitted when SubagentRun.result resolves (any stop reason).

One tool registry fed every agent's prompt (a child spawned to summarize a file was offered bash, file-write, and the delegation tool itself, unbounded); one section list rendered the same persona for everyone (`SubagentStartRequest` could not express a per-child persona at all); every `agent/*`, `session/*`, and `tools/*` listener fired for every agent, so a decider waterfall written for one agent silently governed all of them unless its author remembered to self-filter. The gap was visible in the API: `SubagentCapabilities.toolFilter` was public vocabulary, yet every real provider declared `toolFilter: false` because per-agent tool visibility was unimplementable, and `structured.ts` carried a FIXME documenting the placeholder-schema/final-assembly-swap/refcount dance forced by global registration. + +## Decision + +Make the agent a registration scope, using the framework's own machinery rather than per-registry bolt-ons: + +- **`dsh-scope`** (`packages/core/scope`, peer-deps cordis only, below `dsh-session`/`dsh-system-prompt` in the module-graph DAG): `createScope(ctx, key)` mints a tagged context over a synchronously-usable no-op-plugin fiber; `scopeOf(ctx)` reads the tag through the prototype chain; `scopeTarget(base, key)` builds the scope-filtered dispatch carrier over cordis `Context.filter`, composing the base's own filter, branded `Scoped` and runtime-marked for the dev invariants; `Scope.rawDispose` exposes the exact cordis disposer so a composite effect nests the scope's teardown at its yield position; `scopeHost` is the fail-loud test-side minter. +- **Ownership and visibility derive from ONE fact** — which context a registration went through: the scope's fiber owns the disposal, and the tag decides who sees it. An explicit `{ scope }` registration parameter could express "visible to X, disposed with Y", which is almost always a bug; the scoped context makes it unrepresentable. +- **`Agent.ctx`**: every live agent owns a scope context (key = the agent), minted inside the loop's composite lifecycle effect. Yield order gives teardown stop/drain → unregister → detach session → unwind scope; detach before the (async) scope unwind keeps store/registry rollback synchronous on every failure path, so a caller catching a throwing `create()` observes no half-created agent or session. `CreateAgentOptions.setup(agentCtx)` runs after the scope is minted and the agent registered, before `agent/session-start` and the loop start — setup REGISTERS the scoped world, it never drives (a dev invariant makes a pre-session-start turn a teaching error). +- **Two registration layers with shadowing**: `ctx.tools` and `ctx.systemPrompt` file a registration by the calling context's tag; a scoped tool/section/variable is visible to that agent alone, unwinds with it, and SHADOWS a same-named global contribution for that agent (most-specific-wins; within one layer duplicates still throw). Shadowing is the per-agent persona mechanism (a scoped `deployment:persona`) and the per-agent tool-variant mechanism (a scoped `bash` with the same model-facing name). +- **`tools.restrict({allow?, deny?})`**: a scoped, snapshot-at-registration mask over the GLOBAL tool surface with loud unknown-name validation; multiple restrictions intersect; scoped registrations are explicit grants that bypass restriction (what keeps a structured capture tool alive under an allow-list). One visibility function feeds prompt assembly, `get(name, scope?)`, and `execute`, so what the model is shown, what a presenter renders, and what dispatches can never disagree; out-of-view execution is `UNKNOWN_TOOL`, indistinguishable from nonexistent. +- **Scoped dispatch by rule**: an event about one agent's activity dispatches with that agent's carrier — all `agent/*` (via the fused `agentEvents(ctx, agent)`, which injects carrier and subject in one move so the correct dispatch is the shortest spelling), `session/created|event|flush` (carrier captured at `SessionStore.enter` from the entering context; `ctx.sessions.flush(session)` owns the awaited checkpoint dispatch), `tools/pre|post-execute` (by `exec.agent`), `system-prompt/assemble` (by `context.scope`; `assembleContextFor(agent)` builds the context), and `subagent/start|end` (by the delegating parent). Registry-subject notifications (`tools/change`, `system-prompt/change`, `subagent/provider-*`) stay deliberately unfiltered. A listener registered through `agent.ctx` hears only its agent; plain plugin listeners keep hearing everything; `{ global: true }` bypasses filtering. +- **Enforcement**: dev-invariants assert at cordis's `internal/dispatch` seam that every scoped-family dispatch carries a carrier keyed to the same subject its arguments name, and that an assembly context never carries `agent` without `scope`; the `verify-scoped-dispatch` gate pins the invariant table against the declaration docs so the two cannot drift. +- **The seam becomes honest**: spawn/fork advertise `{ outputSchema, depthLimit, toolFilter, persona }` all true (ACP all false); the driver composes the child's scoped world in the setup window; a parent-scope teardown effect links each child to its parent through the memoized handle (structured concurrency — a disposed parent reaches its subtree even if the delegating tool's `finally` never runs); `structured.ts` collapses to scoped registrations with a call-keyed two-phase commit and one scoped prepend re-assert listener. + +## Alternatives considered + +- **Explicit scope parameters on every registration API** (`tools.register(def, {agent})`): forgettable — omitting the option is global, so leak-by-default survives; no lifecycle coupling; and it can express visible-to-X-disposed-with-Y, which is almost always a bug. +- **Per-agent `ctx.isolate()` service instances**: isolation is a bulkhead for co-hosting independent applications, not intra-app scoping. Resolution picks exactly one instance per name — "deployment tools plus my tools" needs a hand-built delegating merge registry per service — and single-subscription observers (persistence, the ACP bridge) would have to discover and subscribe per agent. +- **Event-filtering only** (scoped listeners, global registries): leaves the model-visible surfaces — tool schemas, personas — unscoped, which is the half that makes `toolFilter` and per-child personas impossible. +- **Vendored-cordis support** (a first-class scope concept in the framework): more invasive vendor drift for no additional capability; `extend` + `Context.filter` + a no-op plugin fiber already compose the same semantics from public primitives. + +## Consequences + +- Plugin authors get one new concept: register through `agent.ctx` for one agent, through your plugin context for everyone.

Per-agent shaping lives here because the tool registry and prompt assembly are context-global while schemas differ per concurrent child (FIXME in the module doc: per-agent/per-session scoping would dissolve this); cooperative mutate-then-`next()` would not survive a downstream listener returning a replacement assembly. -- a `tools/post-execute` listener (`prepend: true` = outermost, so `await next()` yields the composed final decision) that COMMITS the capture: the tool body only stages the validated value, and it becomes the run's result only when the final decision accepts the call — a downstream block (a PostToolUse hook) turns the logged result into `isError`, and the run must not report `structured` success for a call the model and session log saw fail. -- a `tools/pre-execute` deny for any call arriving after the agent's capture — terminal means terminal WITHIN the step: a response listing `structured_output` before further tool calls cannot run side effects after the final answer was accepted. -- an `agent/turn-continuation` listener (also `prepend: true` — an earlier-registered force-continue listener returning without `next()` must not decide the turn before the veto runs) that stops a child's turn once its output is captured, so a successful capture doesn't buy a wasted extra model step. - -The capture tool validates each call against the run's schema (`validateStructuredValue`) — violations become an `INVALID_ARGS` isError result the model retries in-turn; a valid call stages the value for the post-execute commit. - -Lifetime is refcounted by live structured runs: each acquires at start and releases at settle, so the registrations exist exactly while at least one structured child is live, a backend hot-reload mid-run cannot unregister the capture tool under a live child, and the last settle disposes everything. `release()` is idempotent per acquisition. +- the `structured_output` capture tool with the run's REAL schema as its registered `parameters`, validating each call (`validateStructuredValue`) — violations become an `INVALID_ARGS` isError the model retries in-turn; a valid call STAGES the value keyed by its call id; +- the calling instruction as an ordinary order-190 scoped prompt section (the demand travels with the tool, as prompt state of exactly one agent); +- a scoped `system-prompt/assemble` re-assert (`prepend: true` = outermost): whatever downstream listeners mutate or replace, the child's assembly always carries its capture tool and instruction — the loop logs the rendered assembly as the step's `request/header`, so the demand is reconstructable log state; +- a scoped `tools/post-execute` COMMIT (`prepend: true`): the staged value becomes the run's result only when the final decision accepts THE SAME CALL that staged it — call-keyed, so a stale stage orphaned by an outer short-circuiting listener is dropped, never promoted on a later call's acceptance; +- a scoped `tools/pre-execute` deny for any call arriving after the capture — terminal means terminal WITHIN the step; +- a scoped `agent/turn-continuation` veto (`prepend: true`) stopping the child's turn once its output is captured, so a successful capture doesn't buy a wasted extra model step. ### `depthOf(agent): number` diff --git a/packages/subagent/subagent/README.md b/packages/subagent/subagent/README.md index 8bab4c61c9..695bd8f952 100644 --- a/packages/subagent/subagent/README.md +++ b/packages/subagent/subagent/README.md @@ -25,7 +25,7 @@ Unlike the bash seam (one executor per context, second load throws), **multiple ## Capabilities: two kinds, discovered two ways -- **Start-time features** (`outputSchema`, `depthLimit`, `toolFilter`) are a static `provider.capabilities` descriptor, checked by the service BEFORE a run exists.

Regression test pins turn-end before disposed before detach on owner unload. B2: the structured two-phase commit could promote a stale stage when a later capture call REUSED the orphaned stage's call id with a body that never staged (denied downstream, or invalid args throwing pre-stage). The runtime's pre-execute listener now clears any stale stage unconditionally when a new capture call enters the pipeline — only a call's own body can stage for its commit; the call-id mismatch guard becomes a defensive second layer. Repro test: blocked capture then same-id invalid call. C1: an explicit empty toolFilter config now fails at plugin LOAD (the check is self-contained) instead of killing every delegation at child setup.

An omitted agentOptions materializes {}, which is truthy — so every yml-configured load put a dishonest agentOptions: {} on every start request and the presence check in execute() could never be false through config (only unit tests bypassing schemastery ever exercised that branch). Harmless downstream today (the driver only spreads it), but the request shape lied and the check was production-dead. Same discipline as its toolFilter sibling: the omitted key now defaults to undefined, the presence check is spelled !== undefined like its neighbors, and a regression test (fails against the unfixed schema) pins that an omitted agentOptions stays absent from the request. Swept every other Config in the repo for the class: no further instances — omitted primitives inside a materialized object stay ABSENT (verified empirically), so subagent-mock's capabilities spread is safe, and the remaining object/array fields all carry explicit defaults or the forced-undefined discipline already. --- packages/subagent/tool-subagent/src/index.ts | 8 +++-- .../tool-subagent/tests/tool-subagent.spec.ts | 30 +++++++++++++++++++ 2 files changed, 36 insertions(+), 2 deletions(-) diff --git a/packages/subagent/tool-subagent/src/index.ts b/packages/subagent/tool-subagent/src/index.ts index f677076d3f..31d6dce113 100644 --- a/packages/subagent/tool-subagent/src/index.ts +++ b/packages/subagent/tool-subagent/src/index.ts @@ -93,9 +93,13 @@ export interface Config { export const Config: z = z.object({ provider: z.string().required(), toolName: z.string().default('subagent'), + // Omitted-object discipline (see the toolFilter note below): without the + // forced default an omitted `agentOptions` materializes `{}`, which reads as + // present — the request would carry `agentOptions: {}` and the presence + // check in execute() could never be false through config. agentOptions: z.object({ model: z.string(), - }), + }).default(undefined as unknown as { model: string }), persona: z.string(), // A schemastery object materializes {} (with [] for nested arrays) when the // key is omitted — for toolFilter that would mean an EMPTY ALLOW-LIST, i.e. @@ -229,7 +233,7 @@ export function apply(ctx: Context, config: Config): void { prompt: [{ type: 'text', text: args.prompt }], parent, ...exec.signal ? { signal: exec.signal } : {}, - ...config.agentOptions ? { agentOptions: config.agentOptions } : {}, + ...config.agentOptions !== undefined ? { agentOptions: config.agentOptions } : {}, ...config.persona !== undefined ? { persona: config.persona } : {}, ...config.toolFilter !== undefined ? { toolFilter: config.toolFilter } : {}, ...config.maxDepth !== undefined ? { maxDepth: config.maxDepth } : {}, diff --git a/packages/subagent/tool-subagent/tests/tool-subagent.spec.ts b/packages/subagent/tool-subagent/tests/tool-subagent.spec.ts index da560350e4..9d9941fdff 100644 --- a/packages/subagent/tool-subagent/tests/tool-subagent.spec.ts +++ b/packages/subagent/tool-subagent/tests/tool-subagent.spec.ts @@ -511,6 +511,36 @@ describe('dsh-tool-subagent', () => { expect(seen?.toolFilter).not.toHaveProperty('allow') }) + it('an omitted agentOptions does not materialize an empty object onto the request', async () => { + // Same schemastery trap as toolFilter, adjacent field: an omitted + // `agentOptions` config key materializes `{}` without the forced default, + // which reads as present and puts a dishonest `agentOptions: {}` on every + // start request. + let seen: { agentOptions?: unknown } | undefined + const ctx = new Context() + await ctx.plugin(SystemPrompt) + await ctx.plugin(ToolRegistry) + await ctx.plugin(SubagentService) + ctx.subagents.registerProvider({ + name: 'capture4', + capabilities: { outputSchema: false, depthLimit: false, toolFilter: false, persona: false }, + inheritsParentContext: false, + start: (request) => { + seen = request + return { + id: AgentId('capture4-child'), + result: Promise.resolve({ output: [{ type: 'text', text: 'ok' }], stopReason: 'completed' as const }), + cancel() {}, + dispose: async () => {}, + } + }, + }) + await ctx.plugin(tool, { provider: 'capture4' }) + await callSubagent(ctx, { description: 'd', prompt: 'p' }) + expect(seen).toBeDefined() + expect(seen).not.toHaveProperty('agentOptions') + }) + it('an explicit empty toolFilter fails at plugin load, not at first delegation', async () => { const ctx = new Context() await ctx.plugin(SystemPrompt) From 4e8dc8e8f57918e1881889c7d2440f10159d0f4a Mon Sep 17 00:00:00 2001 From: Tianyi Cui <53024+tianyicui@users.noreply.github.com> Date: Thu, 9 Jul 2026 12:36:18 +0800 Subject: [PATCH 066/311] docs: fail the event matrix on a zero-dispatcher row; attribute provider-removed MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The chained-fused-dispatch spelling fix (0dc2fe90) was whack-a-mole: each unrecognized dispatch spelling silently drops a producer edge from the generated matrix, and only a human reading the table catches it. Convert the class to a build failure: the generator now hard-errors when any DECLARED event ends with zero dispatchers — dead vocabulary or a missed spelling, both actionable ('teach the scan or add a DYNAMIC_EVENT_DISPATCHERS override'). Zero LISTENERS stays legal: seven current rows (agent/request, system-prompt/assemble, tools/change, ...) are ordinary extension points dispatched for out-of-repo plugins. The guard caught a real one on its first run: subagent/provider-removed routes through the same contained events.dispatch as subagent/start|end (it fires inside the provider registration's disposer), but the DYNAMIC_EVENT_DISPATCHERS override list never got an entry when that containment routing was introduced — the committed matrix (on master too) claimed the event has NO dispatcher while tool-subagent listens for it.

A wrapper makes correct composite usage unrepresentable — the exact disposer cannot be recovered, so a generator effect yielding it leaves the inner effect disposing as a CONCURRENT SIBLING on owner unload, silently reproducing B1's ordering corruption. The exact disposer serves both usages (composite-nestable AND fire-and-forget callable); all seven now return it, typed () => Promise | void, with the convention pinned by a discriminating test: an async-link composite probe that passes with the exact disposer and observes the sibling unregistration firing mid-drain with a wrapper. Re-auditing also surfaced that B1 itself SHIPPED a full-lint failure: it changed register()'s return type without updating cross-file consumers (agent.spec.ts dispose() statements, tool-bash's disposer list), which the staged-scoped pre-commit lint never saw — pnpm run lint was red at HEAD. Those three sites and this change's own fallout are fixed together: tests now await disposers (stronger — they observe the full unwind), sync paths void them, and the two annotation sites carry the honest union type. agents.register's README line had drifted the same way (B1 updated the JSDoc, not the README) — all seven README signatures now match; services catalog regenerated. --- docs/cordis-catalog/services.md | 14 +++--- packages/bash/tool-bash/tests/tools.spec.ts | 4 +- packages/core/agent/README.md | 4 +- packages/core/agent/src/index.ts | 12 +++-- packages/core/agent/tests/agent.spec.ts | 6 +-- packages/core/system-prompt/README.md | 6 +-- packages/core/system-prompt/src/index.ts | 48 +++++++++++++------ .../core/system-prompt/tests/scoped.spec.ts | 2 +- .../system-prompt/tests/system-prompt.spec.ts | 8 ++-- packages/core/tools/README.md | 4 +- packages/core/tools/src/index.ts | 32 +++++++++---- packages/core/tools/tests/scoped.spec.ts | 2 +- packages/core/tools/tests/tools.spec.ts | 33 ++++++++++++- .../tests/structured.spec.ts | 2 +- packages/subagent/subagent/src/index.ts | 16 +++++-- .../subagent/subagent/tests/service.spec.ts | 8 ++-- packages/subagent/tool-subagent/src/index.ts | 4 +- 17 files changed, 138 insertions(+), 67 deletions(-) diff --git a/docs/cordis-catalog/services.md b/docs/cordis-catalog/services.md index 3dc09d3fa3..783ef7c83e 100644 --- a/docs/cordis-catalog/services.md +++ b/docs/cordis-catalog/services.md @@ -28,7 +28,7 @@ Source: [`packages/core/agent-loop/src/index.ts:70`](../../packages/core/agent-l Agent registry (`ctx.agents`): tracks live agents so UI, hook, and orchestrator plugins can find them without depending on the concrete loop package.

The withProps-based carrier delegated gets with the PROXY as receiver, so ReactLoopAgent's send/steer/cancel — which read the native-private #carrier through a getter — threw TypeError when called that way (private members do not exist on proxy receivers). scopeTarget now builds its own proxy: overlay props (the composed filter and the carrier mark) answer from a null-shadowed literal via hasOwn (`in` would let Object.prototype's toString/constructor shadow the subject's), every other get delegates with the BASE as receiver (getters see the real object) and returns functions bound to the base (method calls execute on the real receiver), sets land on the base.

implemented + +## Problem + +The bash capability seam supports both foreground commands and long-running background tasks. Background support was large: the abstract executor exposed `start`, `get`, `ownerOf`, `list`, `readOutput`, `kill`, and `onTaskDone`; the local executor tracked tasks, incremental reads, owner tokens, process cleanup, and completion listeners; the model saw three tools (`bash`, `bash_output`, `bash_kill`); the tool plugin injected completion notices back into the owning agent's session. The local executor fenced task access behind owner tokens because predictable global task ids are a cross-session read/kill hazard. + +The [tool cookbook](../../../cookbook/adding-a-tool.md) already pointed at the real design smell: background bash is really generic long-running-tool infrastructure living inside one tool. The pressure stopped being hypothetical with [background subagent tasks](../feature/2026-07-08-background-subagent-tasks.md), which needs the same task ids, owner isolation, polling, stop, completion notices, and prompt guidance, and whose first draft answered by cloning the protocol under new names (`subagent_wait`, `subagent_output`, `subagent_stop`) and reshaping `dsh-tool-subagent` into a multi-tool plugin solely so the cloned companion tools would not collide across instances. Every future long-running capability (dev servers, watchers, remote jobs) would clone it again, and the model would learn a new collect/stop habit per capability. + +The surveyed peer products converged on the opposite shape. Claude Code exposes one `TaskOutput`/`TaskStop` pair spanning seven task kinds (background shells, subagents, remote sessions, …), with its earlier per-capability `BashOutput`/`KillShell` names kept only as aliases; Kimi Code's `BackgroundManager` runs process, agent, and pending-question kinds behind the same two tools and a ~5-method producer interface; DeepSeek-Reasonix serves bash and delegation from one session-scoped jobs manager; OpenCode's `BackgroundJob` registry is kind-agnostic by construction. The lesson is that the task registry, the control tools, and the notification path are one capability, and the producers (bash, subagents) are plugins into it. + +## Decision + +The `tasks/` package group owns background-task semantics once, and bash and subagents are producers: + +- `@deepseek-ai/dsh-tasks` — the task registry service (`ctx.tasks`): branded task ids, owner-scoped authorization, status snapshots, incremental/final output reads, cancellation, wait-for-terminal, completion listeners, and the awaited owner-cleanup path. +- `@deepseek-ai/dsh-tool-tasks` — the model-facing control surface: `task_output`, `task_list`, `task_kill`, the completion-notice injection into the owning session, and the system-prompt section that teaches the background-task habit. + +Producers register running work into `ctx.tasks` and stay owners of their execution concerns: `dsh-tool-bash`'s `run_in_background` path registers the process it started (incremental stdout, spill formatting, kill), and `dsh-tool-subagent`'s background mode ([the feature RFC](../feature/2026-07-08-background-subagent-tasks.md)) registers the child run (final output only, cancel + dispose). The bash seam carries no registry: `bash_output`/`bash_kill` no longer exist (the generic tools replaced them), and the subagent companion tools were never created. The `dsh-agent-core` bundle loads the pair, so every shipped deployment has the control surface. + +The registry is a CONCRETE service, not an interface/implementation seam pair: there is exactly one sensible in-process implementation today, and the capability-seam convention says not to split preemptively. The pre-release stance lets a later durable/remote job system extract an interface when a second backend actually exists. + +## Task model + +`dsh-tasks` owns the vocabulary ([data-structure catalog](../../../core-data-structures/tasks.md)). `TaskId` is branded, generated by the registry as `-N` with a per-kind counter (`bash-1`, `subagent-1`) — the kind prefix keeps ids self-describing in transcripts and preserves the pre-runtime `bash-N` shape. Ids are runtime-global and predictable, so every access is authorized (below). + +A producer registers a task with: + +```ts ignore-check +interface TaskRegistration { + /** Producer kind — also the id prefix ('bash', 'subagent', …). */ + kind: string + /** One-line model-facing label (the command; the delegation description). */ + label: string + /** The spawning agent; undefined = unowned (open access, dies with the service). */ + owner?: Agent + /** Request termination; idempotent; must lead to `done` settling. The optional reason is `task_kill`'s logged reason, forwarded. */ + cancel(reason?: string): void + /** Settles at QUIESCENCE — after the producer has released the task's resources. Never rejects. */ + done: Promise + /** OPTIONAL incremental read (stream kinds). Consecutive calls never re-deliver output; the producer owns truncation/spill formatting. Absence = final-output-only kind. */ + readOutput?(): string +} + +interface TaskOutcome { + status: 'completed' | 'killed' | 'failed' + /** Kind-specific detail rendered into the status line ('exit code: 3', 'max-tokens'). */ + detail?: string + /** Final output for final-only kinds; read idempotently after the task settles. */ + output?: string +} +``` + +The task status vocabulary is generic and closed: `running`, `stopping` (cancel requested, not yet settled), and the three terminal values above. Kind-specific meaning rides in `detail`, so the registry never learns process or agent semantics — the method presence (`readOutput`) is the capability, mirroring `SubagentRun.sendMessage`. + +The registry attaches ONE continuation to `done`: record the terminal snapshot, then notify task-done listeners with per-listener containment (the guarantee the bash seam's `notifyTaskDone` used to give its own listener set). `done` settling at quiescence — not merely at completion — is what makes owner cleanup and service disposal awaitable without a second completion surface; this resolves the old seam's duplication of a per-task `done` promise AND a global `onTaskDone` registry by making the promise the producer contract and the listener registry the consumer surface. + +Registrations are NOT effect-scoped to the registering fiber: a task belongs to its owning agent and its producing backend, not to the tool plugin whose call started it, so an HMR reload of `dsh-tool-bash` or `dsh-tool-tasks` never orphans or kills a running task (the same argument that used to keep bash ownership in the executor). The registry's own disposal cancels every live task and awaits settlement — no orphans survive `fiber.dispose()`. + +## Authorization and the service surface + +Cross-session isolation lives IN the runtime so every consumer gets the same rule for free: read/kill/wait/get take the caller (`Agent | undefined`), and a task whose owner session differs from the caller's session is rejected (`!== undefined` comparison — an unowned task is open, a no-agent caller cannot match an owned task). `list(caller)` returns only the caller-visible tasks (owned-by-caller or unowned) — a global listing would leak other sessions' labels. Owner identity is `session.header.id`, the canonical id every other subsystem keys on; because both sides of the comparison come from live `Agent`s, the freestanding `OwnerToken` brand the bash seam used to carry became internal state rather than a seam type. + +```ts ignore-check +class TaskService extends Service { // ctx.tasks + register(reg: TaskRegistration): TaskId // throws when no control surface is attached; ATOMIC — a throw mutates nothing + get(id: TaskId, caller?: Agent): TaskSnapshot // non-consuming; throws: unknown id, foreign owner + list(caller?: Agent): TaskSnapshot[] // caller-visible only + read(id: TaskId, caller?: Agent): TaskRead // delta (stream kinds, consuming) or final output (final kinds, idempotent) + snapshot + kill(id: TaskId, caller?: Agent, reason?: string): 'requested' | 'already-terminal' + wait(id: TaskId, timeoutMs: number, caller?: Agent, signal?: AbortSignal): Promise + onTaskDone(listener: (snapshot: TaskSnapshot) => void): () => void // effect-scoped, contained, never fires after dispose + attachSurface(name: string): () => void // the misconfiguration fence, below +} +``` + +`TaskSnapshot` is the read-only projection: id, kind, label, owner session, status, detail, started/finished timestamps, and the `reported` notice-suppression flag (below). `wait` resolves with the terminal snapshot, or with the still-`running` snapshot on timeout; aborting the wait cancels only the wait. + +**Misconfiguration fails loud**: a deployment that loads a background-capable producer without any control surface would let the model start tasks it can never read or stop — the half-loaded failure mode the subagent RFC's first draft reshaped a whole plugin to avoid. The fence is `attachSurface()`: `dsh-tool-tasks` attaches (effect-scoped) on load, and `register()` throws `background tasks unavailable: no control surface is attached (load @deepseek-ai/dsh-tool-tasks)` when none is attached — the earliest self-contained moment, since concurrent plugin start makes a load-time check racy. The registry stays ignorant of tool names; a deployment with a custom (non-model) surface attaches its own. + +## The model-facing control tools + +`dsh-tool-tasks` registers three kind-agnostic tools (ACP render intent: `generic` cards, `kind: 'execute'` for kill and `'read'` for output/list, no `locations`): + +- `task_output(task_id, wait?, timeout_ms?)` — non-blocking by default: stream kinds return output produced since the previous read, final kinds return only a status line while running and the final output once terminal; every response ends with the status line (`[status: running]`, `[status: completed, exit code: 0]`, `[status: failed, max-tokens]` — generic status + producer detail). `wait: true` blocks until the task settles or the timeout expires (config: defaulted `waitTimeoutMs`, capped `maxWaitTimeoutMs`); a timed-out wait returns `[status: running]` and leaves the task alive. Polling-by-default preserves the established bash habit; `wait` is what a parent uses when it is genuinely blocked on a subagent's answer. +- `task_list()` — the caller's tasks, one line each: ` [] —
