test-validator

Run the project's test suite and return failures as agent-readable JSON. Use after writing or modifying code, before declaring done, or when the user says "run tests", "check tests", "did anything break". Wraps pnpm test --reporter=json — much faster for an agent to parse than scrolling colored console output. Returns {passed, failed, duration_ms, failures: [{file, test, line, error}]}. NOT a replacement for pnpm check (typecheck + lint + test) — use that as the full pre-ship gate. This skill is targeted: just the test outcomes.
