# PUT /projects/{projectId}/review/schemas

`PUT /projects/{projectId}/review/schemas`

## Request

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

PUT /api/v1/projects/{projectId}/review/schemas on the Caveman Cloud control plane. Requires the eval:write scope. Exposed to autonomous agents as the set_review_schema 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.

## Request body

  - `criterion_id` string, uuid, nullable
  - `schema` object, required
