Three-stage code review protocol covering spec compliance, code quality, and domain integrity. Use this skill whenever the user asks to review code, prepare or check a PR, assess implementation quality, verify code against a spec or acceptance criteria, or audit for security and domain modeling issues. Triggers on: "review this code", "review my PR", "check implementation against spec", "code quality audit", "does this match the requirements", "review for security issues", "check for primitive obsession", "monetary precision review", "review test coverage gaps". Also activates when the user wants structured PASS/FAIL verdicts per requirement, severity-rated findings, or a gated review that blocks on critical issues. NOT for: style/formatting linting, debugging runtime errors, writing new code, or automated CI checks.
