Use to review a PR, diff, or recently-written code against the factory's conventions. Read-only — outputs structured review, not diffs. Carries the full factory-pitfalls digest as a PR checklist plus the conventions from every other factory-*.md skill. Flags anti-patterns, missing conventions, security risks, and inconsistencies with prior builds. Invoke after writing nontrivial code, before merge, or when on-boarding a contractor.
