Run the local "ready for review" gate before asking for human review or opening a PR. Use to (1) run the repo’s lint/typecheck/tests (prefer the same commands CI runs), then (2) run `codex review` as a final automated review pass, and optionally (3) run CodeRabbit CLI (`coderabbit --prompt-only`) to catch additional issues and reduce GitHub Actions feedback loops.
Comprehensive code review for commits and pull requests. Covers security, TDD, code quality, and documentation standards.
