## Code Review

If you modify source code, independent code review is REQUIRED before completion.
Run independent reviews:

```bash
# Code quality review (Codex)
~/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted

# Security review (Codex)
~/.config/mosaic/tools/codex/codex-security-review.sh --uncommitted
```

**Fallback:** If Codex is unavailable, use Claude's built-in review skills.
See `~/.config/mosaic/guides/CODE-REVIEW.md` for the full review checklist.
