Run test cases against a policy

POST
/v1/policies/test
curl --request POST \
  --url http://127.0.0.1:8080/v1/policies/test \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --header 'Deedglass-Version: 2026-10-01' \
  --data '{ "policy": "postgres-safe", "version": 3, "cases": [ { "name": "deletes never run", "input": { "tool": "postgres.execute", "sql": "DELETE FROM public.orders" }, "expect": { "decision": "deny", "rule": "block-destructive-sql" } } ] }'

Runs a cases file against a source, or against a stored version (policy and version), and reports each case and the rule coverage. Send source or policy with version, not both. It never reserves usage and writes nothing. Limited to 60 requests a minute per person or key (429 rate_limited), with a 2 s timeout and bodies up to 2 MiB. Idempotency-Key is ignored. A Console session (viewer and up, with the Deedglass-CSRF header) or an org admin key (admin scope); agent keys get 403 insufficient_scope (“Agents cannot read or test policies. Use the Console or an admin key.”).

Deedglass-Version

Deedglass-CSRF
string

Needed when the request uses a Console session (it changes state); without it the answer is 403 csrf_failed. Not sent with an API key.

diagnostics

On policy_invalid only. Each problem with its line, code and hint.

Array<object>

One finding about a policy file, with its position and the next step. Codes are stable and listed in docs/POLICY_ERRORS.md. In the policy_invalid error envelope each diagnostic also carries object: policy_diagnostic. The full PolicyDiagnostic schema is in openapi.yaml.

object
action

One agent action. Its sections mirror the deed’s. status is the one field an agent needs; state is the exact lifecycle state (docs/GATE.md). The Gate’s own responses (POST /v1/actions and its result report) add execution.result and witness.reasons; lists leave both out. The full Action schema is in openapi.yaml.

object
checks

On undo_unavailable only. Every check of the undo, each with its fix. Additive (S23).

Array<object>

One of the twelve safety checks (S23 §3.3). Available means no check failed. The full UndoCheck schema is in openapi.yaml.

{
  "error": {
