The bundle ships two rows: the workspace's tools bridged to the model, and the harness-side behavior a tool bridge cannot provide on its own — a supervised workspace session that delivers AgentRQ's pushes into the live agent, and the AgentRQ working agreement as a system-prompt section. + +## Install + +**Requires pnpm.** `dsh plugin` is a thin forwarder to `pnpm` for every profile — installing any plugin, this one included, fails with `pnpm not found on PATH` unless pnpm is already installed (`npm install -g pnpm`, `corepack enable pnpm`, or `brew install pnpm`). This is a DeepSeek Harness CLI requirement, not something this plugin can opt out of. + +**One profile per workspace.** A profile serves one AgentRQ workspace and carries its own endpoint, so name it after the workspace rather than using `default` — that is what makes [several workspaces](#multiple-workspaces) work. Your workspace's **Settings → Setup → DeepSeek Harness** page prints every command and config block below already filled in. + +```sh +dsh plugin --profile agentrq- add @agentrq/dsh-plugin-agentrq +``` + +Then pin this workspace's endpoint in the profile's own patch layer, `~/.dsh/profiles/agentrq-/cordis.patch.yml`.

Supply neither and the row fails to load with the `url` field named — it is a required field, not a silent default. + +Installing from a git checkout instead of the registry fetches sources rather than built artifacts, so pnpm must be allowed to run this package's `prepare` build. Add the allowance to your profile's `pnpm-workspace.yaml` and re-run the `add`: + +```yaml +allowBuilds: + '@agentrq/dsh-plugin-agentrq': true +``` + +That allowance is permission to execute this package's code on your machine at install time. Pin a commit (`github:agentrq/agentrq#`) if you take that route. Publishing to npm or shipping a `pnpm pack` tarball avoids the allowance entirely. + +## What the model gets + +Seven AgentRQ tools, bridged by `@deepseek-ai/dsh-mcp-client` under the `agentrq` namespace: + +| Tool | Purpose | +|---|---| +| `mcp__agentrq__getTask` | Fetch a task, or dequeue the next one assigned to this agent | +| `mcp__agentrq__createTask` | Assign work to the human or to another agent | +| `mcp__agentrq__updateTaskStatus` | Move a task to `ongoing`, `completed`, `blocked`, … | +| `mcp__agentrq__reply` | Send a message into a task thread — the only thing the remote human sees | +| `mcp__agentrq__getWorkspace` | Read the workspace title and mission | +| `mcp__agentrq__downloadAttachment` | Fetch an attachment's content | +| `mcp__agentrq__publishEvent` | Fire a named event so subscriber workspaces spawn their trigger tasks | + +Plus one tool this package owns: + +| Tool | Purpose | +|---|---| +| `agentrq_autopull` | `status`, `pause`, `resume`, or `pull_now` for this session's AgentRQ delivery | + +`pull_now` returns the dequeued task as its own tool result rather than queuing a turn, because a tool body runs mid-turn by definition. + +## How work arrives + +**The plugin does not poll.** AgentRQ already decides when there is work and pushes it over `notifications/claude/channel`: + +- creating a task assigned to the agent pushes it immediately (`backend/internal/handler/api/task.go`), provided nothing else is ongoing; +- `WorkspaceServer.StartPoller` re-pushes the next unclaimed task — or a status check for the ongoing one — every 60 seconds. + +The plugin's own workspace session subscribes to that channel, exactly as [`acp-gateway`](https://github.com/agentrq/agentrq-acp-gateway) does for Gemini and other ACP agents. Polling the queue from the client would duplicate the server's own ticker and deliver every task twice. + +Each push is forwarded **as written**. A new task, the periodic reminder, a status check, and a human's reply all arrive on the same channel; the plugin adds a framing line naming the `chat_id` and the tools to answer with, then hands over the content. It does not try to classify what kind of push it is, because that would only add a way to be wrong. The content is JSON-escaped into the framing, so pushed content cannot forge a framing field. + +Delivery route depends on the agent's state: `inject()` while a turn is running, so it lands at the next step boundary, and `followup()` while idle, since nothing else would wake it. Neither interrupts a turn in flight. + +`SendChannelNotification` puts the task id in `meta.chat_id` on every push, so the id never has to be recovered from the content. + +**Repeats are dropped.** The workspace re-pushes an unclaimed task verbatim every minute; the runtime remembers recent `(task, content)` pairs, so the agent is handed it once and not woken every sixty seconds for work it already has. A genuinely new message on the same task still gets through. + +**Staying connected is the load-bearing part.** No session, no pushes — so a closed transport or an unrecoverable transport error triggers a reconnect with exponential backoff (`reconnect.initialDelayMs` doubling to `reconnect.maxDelayMs`), on top of the SDK's own SSE resumption. Because the server re-pushes on its own schedule, a recovered session catches up on the next tick without any client-side replay. + +`catchUpOnStart` dequeues one task when the session opens, so work that predates the connection does not wait for the server's next tick. A failed startup check costs latency, not work. + +`agentrq_autopull pause` stops pushes from reaching the session; the session itself stays open. + +One AgentRQ queue serves one worker, the harness Web UI creates a root agent per chat session, and pushes are broadcast to **every** connected session. Under the default `scope: single-agent`, exactly one live root agent holds the workspace session, so a second chat session does not get every task delivered a second time; a later session inherits the connection only after the owning agent is gone. Set `every-agent` when your agents work disjoint queues or you want deliberate fan-out. + +## Multiple workspaces + +AgentRQ users normally have several workspaces, each with its own queue, mission, and agent identity. **Run one profile per workspace.** + +Install once per profile, and let each profile's `cordis.patch.yml` carry its own endpoint: + +```sh +dsh plugin --profile agentrq-acme add @agentrq/dsh-plugin-agentrq +dsh plugin --profile agentrq-beta add @agentrq/dsh-plugin-agentrq +# …then pin acme's URL in ~/.dsh/profiles/agentrq-acme/cordis.patch.yml +# and beta's URL in ~/.dsh/profiles/agentrq-beta/cordis.patch.yml + +dsh --profile agentrq-acme # terminal 1 +dsh --profile agentrq-beta # terminal 2 +``` + +Because the endpoint lives in the profile rather than the environment, switching workspaces is switching profiles — nothing to re-export, and no way to start one workspace's profile pointed at another's queue. + +Each profile gets its own process, sessions, working directory, and workspace connection, which matches how AgentRQ already models a workspace: one workspace, one agent, one mission. It also matches the usual case where workspaces track different repositories. + +Two consequences worth knowing: + +- **A single profile cannot serve two workspaces.** Mounting the bundle twice in one profile registers the `agentrq:protocol` prompt section and the `agentrq_autopull` tool twice in the same layer, and both registrations throw on a duplicate name. Namespacing them per instance is deferred until someone needs it. +- **No cross-workspace view.** AgentRQ's CoreMCP supervisor (`https://mcp.agentrq.com/mcp`) does expose `listWorkspaces` and `listAllTasks`, so a deployment that wants "what is outstanding everywhere" can mount it as an extra `@deepseek-ai/dsh-mcp-client` row. It sends no channel notifications, so it complements per-workspace delivery rather than replacing it. + +`serverName` is safe to change: the guidance section and every framing derive their tool names from it, so the namespace the model sees and the namespace the prose describes cannot drift apart. + +## Config + +| Key | Default | Meaning | +|---|---|---| +| `url` | — (required) | Workspace MCP endpoint, including its `?token=` credential | +| `token` | `''` | Bearer token, for deployments that prefer an `Authorization` header over `?token=` | +| `mountBridge` | `true` | Mount the `@deepseek-ai/dsh-mcp-client` child that gives the model AgentRQ's tools | +| `serverName` | `agentrq` | Namespace for the bridged tools; the guidance section and framings follow it | +| `deliverPushes` | `true` | Deliver the workspace's tasks and messages into the live session | +| `catchUpOnStart` | `true` | Dequeue one task when the session opens | +| `scope` | `single-agent` | Whether one root agent or every root agent holds a workspace session | +| `reconnect.initialDelayMs` | `1000` | Delay before the first reconnect attempt | +| `reconnect.maxDelayMs` | `900000` | Ceiling for the reconnect backoff | +| `guidance` | `true` | Contribute the AgentRQ working-agreement system-prompt section | +| `requestTimeoutMs` | `30000` | Timeout for one AgentRQ tool call | + +Set any of these in the same profile patch. A patch replaces a row's whole `config` rather than merging into it, but every key except `url` has a schema default, so a row only restates what it changes: + +```yaml +- id: agentrq + name: '@agentrq/dsh-plugin-agentrq' + config: + url: "https://.mcp.agentrq.com/mcp?token=" + catchUpOnStart: false + reconnect: + initialDelayMs: 2000 + maxDelayMs: 60000 +``` + +## The prompt section + +AgentRQ's MCP server ships its collaboration rules as server `Instructions`, and the harness does not surface an MCP server's instructions to the model. Without them the model has the tools but not the contract — that the human is remote, sees only what `reply` sends, and needs the task claimed before work starts. This package contributes those rules as the `agentrq:protocol` section in the tool-guidance band (order 150), so behavior in dsh matches behavior in the Claude Code and Gemini extensions. Turn it off with `guidance: false` when a deployment states the same protocol in its own persona. + +## Development + +```sh +npm install --legacy-peer-deps # harness packages declare peers pnpm resolves from the profile +npm run typecheck +npm test +npm run build +``` + +`make plugin-deepseek` from the repository root runs all four. + +## Releasing + +`.github/workflows/plugin-deepseek-harness.yml` typechecks, tests, and builds this package on every pull request that touches `plugins/deepseek-harness/**`, and publishes it to npm when such a change lands on `main`. + +**Bumping `version` in `package.json` is what releases.** npm refuses to republish an existing version, so the workflow checks first and skips the publish when the current version is already on the registry — an ordinary fix that touches this path does not need a version bump to merge. + +Authentication is [npm trusted publishing](https://docs.npmjs.com/trusted-publishers): the package names `agentrq/agentrq` and this workflow file as its trusted publisher, the job requests an OIDC token with `id-token: write`, and npm exchanges it for a short-lived publish credential. There is no `NPM_TOKEN` secret to store, rotate, or leak, and npm attaches build provenance automatically. + +Two things that break it, both non-obvious: + +- **Renaming the workflow file.** The trusted-publisher record names `plugin-deepseek-harness.yml` exactly; a rename must be made on npm's side too or every publish is rejected. +- **npm older than 11.5.1.** `setup-node` with Node 22 installs npm 10.x, which has no OIDC support and silently falls back to looking for a token. The workflow upgrades npm explicitly for this reason — do not remove that step. + +## Known limitations and deferred work + +- **One workspace per profile** — each row carries one `url`, and mounting the bundle twice in one profile collides on the prompt-section and tool names. [Several workspaces means several profiles](#multiple-workspaces). +- **The endpoint is configured, not discovered** — there is no in-harness command to switch workspaces; the profile's `cordis.patch.yml` (watched, so no restart needed) or `AGENTRQ_WORKSPACE_MCP_URL` is the switch. A `ctx.settings` namespace would give a schema-driven editor with `role('secret')` redaction for the token, but its document is `$DSH_HOME`-global by default and so does not carry per-profile values without extra plumbing. +- **The bridge is mounted, not injectable** — the plugin mounts one `@deepseek-ai/dsh-mcp-client` child with the settings it derives from its own config. A deployment that needs the bridge's other knobs sets `mountBridge: false` and mounts its own row, and is then responsible for keeping `serverName` aligned. +- **Load-order boundary** — the plugin attaches only to root agents published after it loads; an agent that was already live when the plugin loaded gets no workspace session and no `agentrq_autopull` tool. +- **Ownership does not migrate to a live agent** — under `single-agent`, when the owning agent is disposed the connection stops until the *next* root agent is created; an already-open second session does not adopt it. +- **Session-lifetime repeat memory** — the delivered-set is process-local and bounded, so a restarted harness may be handed a task it saw before if that task is still unclaimed. Claiming a task with `updateTaskStatus` is what stops the workspace re-pushing it. +- **Auth is the URL's credential** — the plugin does not run the AgentRQ OAuth authorization-code flow; it uses the long-lived token from Workspace Settings, as a bearer header or a `?token=` query parameter. +- **Attachments travel through the model** — the plugin's own session only receives pushes and dequeues on request; `downloadAttachment` remains a model-facing tool call on the bridged server. +- **Permission verdicts are not bridged** — `acp-gateway` also consumes `notifications/claude/channel/permission` to answer AgentRQ's allow/deny prompts. The harness has its own `tools/pre-execute` approval axis, and wiring the two together is deferred. + +## License + +[Apache-2.0](./LICENSE), matching the rest of the AgentRQ repository. diff --git a/plugins/agentrq/cordis.patch.yml b/plugins/agentrq/cordis.patch.yml new file mode 100644 index 0000000..e466e78 --- /dev/null +++ b/plugins/agentrq/cordis.patch.yml @@ -0,0 +1,18 @@ +# The @agentrq/dsh-plugin-agentrq bundle patch.
