# List Pinned Workers

`GET /workers/pinned`

## Query parameters

- `search` string, nullable — Case-insensitive substring search over worker display name, rendered status, and status message

## Response `200`

Successful Response

- ListPinnedWorkersResponse
  - `workers` WorkerListItemResponse[], required
    - `id` string, required
    - `resource_id` string, required
    - `display_name` string, required
    - `platform` 'slack' | 'teams' | 'web', required — A supported chat platform. Values align with ``integration_instances.type`` so a chat install's platform and its integration row stay in lockstep.
    - `agent_type` string, required
    - `mode` 'incident' | 'alerts' | 'custom', required — The kind of channel the agent lives in — its standing mission. Drives the swappable mode block in the system prompt (and, later, the toolset). ``escalation`` and others land as localized drop-ins (their standing block + tooling) when that work begins. ``incident`` and ``alerts`` each state a mission the worker owns whatever the operator writes. ``custom`` states none: it supplies only the conduct floor the identity block forward-references, and the operator's ``custom_instruction`` is what gives the worker something to do. A channel that is neither working an incident nor triaging alert fires gets this one rather than being told it is in an incident (PRD-3766). The value is what customer-facing surfaces render, so it reads as the operator's own word for it rather than as an internal category. A member's *name* is persisted, in ``resident_agent_workflow.mode`` and ``resident_agent_template.mode`` — plain varchars with no DB-side value set — and read back through this enum, so adding a member is one deploy but removing or renaming one orphans every row holding it. It also makes a member forward-only: code that predates it raises on a row that carries it, rather than degrading. So a new member wants its read deployed everywhere before anything can write it — either landing the member ahead of the paths that create it, or gating creation while it rolls out.
    - `created_at` string, date-time, required
    - `updated_at` string, date-time, required
    - `stopped_at` string, date-time, nullable, required
    - `status` 'critical' | 'attention' | 'working' | 'stable', required — The worker's present-tense status top-line, shown as a pill on the /workers list. Only these agent-picked values are ever stored in the `status` column; a null column means none has been emitted yet (the UI renders that as `starting`), and the terminal `stopped` state is derived from `stopped_at` — neither is stored here, so there is no second source of truth. The agent-facing definitions live on the ``status`` field in ``prompts.py`` (the only copy the model reads); keep this summary in sync with it. Values: CRITICAL: Immediate coordinated response is warranted because user-facing impact is severe or escalating. ATTENTION: A specific person or team should act now, but immediate coordinated incident response is not warranted. STABLE: Resting floor — no specific person or team needs to act now and no coordinated incident response is warranted. WORKING: Legacy — no longer emittable, see ``EmittableWorkerStatus``.
