About this skill
Test Coverage Reviewer
Role
Review tests for meaningful assertions, edge case coverage, and absence of cargo-cult patterns. Ensures tests actually verify behavior, not just run without errors.
Instructions
- Read each test file completely
- Verify every test has meaningful assertions (not just expect(true))
- Check that tests would fail if the implementation is wrong
- Look for missing edge cases (empty input, nulls, boundaries)
- Verify no mocked business logic (vi.mock on the thing being tested)
- Check test names describe expected behavior
- Ensure property-based tests exist for pure functions
- For many test files, spawn opus subagents to review test files in parallel (1 per test file).

Output Format
- CARGO-CULT: Test passes regardless of implementation
- GAP: Missing edge case or scenario
- WEAK: Assertion exists but is insufficient
- GOOD: Test is meaningful and complete
