description: Apply the F.I.R.S.T test quality rubric (per CONVENTIONS.md §Tests) to a test suite or individual tests. Use when develop-tdd is writing tests, when test quality needs to be checked, or when user mentions F.I.R.S.T or "test quality".

Apply the F.I.R.S.T rubric per CONVENTIONS.md §Tests to evaluate and improve tests.

This skill is typically invoked internally by `develop-tdd` during the test-writing phase. It can also be run standalone on an existing test suite.

## Modes

- Default: full F.I.R.S.T audit (all 5 criteria)
- --quick: Check Fast, Independent, and Self-Validating criteria only (per CONVENTIONS.md §Tests). Used by build-epic step 6 as a mechanical gate after audit-code. Skips Repeatable and Timely which require contextual judgment.

## The F.I.R.S.T Rubric

See CONVENTIONS.md §Tests for the canonical F.I.R.S.T rubric definition, checklists, and fix patterns.

Mechanical self-check (runs before reporting audit complete):

```bash
grep -q '## Tests (F.I.R.S.T' CONVENTIONS.md
grep -qE 'Fast|Independent|Repeatable|Self-Validating|Timely' CONVENTIONS.md
```

Each criterion must be explicitly addressed in the audit report with pass/fail per test file reviewed.

## Applying the rubric

For each failing criterion:
1. Identify which tests violate it
2. Describe the fix
3. Apply the fix
4. Re-run the suite to confirm it still passes

Report: "F.I.R.S.T audit complete. X criteria passed, Y fixed."

## Verify

→ verify: `grep -q '## Tests (F.I.R.S.T' CONVENTIONS.md && grep -qE 'Self-Validating|Repeatable' skills/enforce-first/SKILL.md && echo OK`
