# POST /projects/{projectId}/agent-runs

`POST /projects/{projectId}/agent-runs`

## Request

- Base URL: `https://api.caveman.so/api/v1`
- URL: `https://api.caveman.so/api/v1/projects/{projectId}/agent-runs`
- Auth: one of:
  - OAuth 2
    - Authorization code: `/api/v1/oauth/authorize`
    - Token URL: `/api/v1/oauth/token` scopes: `proposal:draft`
  - HTTP bearer
  - API key in cookie `cave_access`
  - API key in cookie `__Secure-cave_identity.session_token`

POST /api/v1/projects/{projectId}/agent-runs on the Caveman Cloud control plane. Requires the proposal:draft scope. Exposed to autonomous agents as the run_agent action of the caveman_evals_write tool (write access). Author versioned datasets, reusable evaluators and workbenches; create strict suites, ingest evidence, and run baselines. Evidence ingest supports dry_run — always dry-run first. Ask Caveman to draft quality criteria again within the drafting allowance, propose a criterion for a person to turn on, and hold the pull request that adds the Caveman check to CI. Track a criterion on a slice of traces in one step: from an agent it lands proposed, and a person turns it on. Queue units for review and label them (an agent's label is recorded as an agent's, never as human gold), and make a dataset from recorded traffic. Native user endpoint. Scoped agent sessions and workload credentials cannot call this operation. Organization budget edits additionally require billing:write. Interactive grants bind current membership and role; input, audit, run and outbox admission commit atomically. Reuse the same request identity, input and deadline on retries.

## Request body

- object
  - `parent_run_id` string, uuid
  - `request_id` string, uuid, required

## Other responses

- `400`: Invalid or missing explicit configuration/input.
- `401`: Authentication required.
- `403`: Native user lacks authority.
- `404`: Requested resource or current authority unavailable.
- `409`: Revision/input conflict or budget unavailable.
