hyperlane-xyz Code Review Skill
Use this skill to review code changes against Hyperlane monorepo standards.
When to Use
- Before committing changes (self-review)
- When asked to review a PR or diff
- To check if changes follow project patterns
Instructions
Read and apply the guidelines from REVIEW.md to review the code changes.
When delegating the review to subagents/teams, pass REVIEW.md to each one so every checklist item (e2e tests, casts, allocations, enums) is actually applied — findings the rules already cover should never slip through.
For PR Reviews
When reviewing a PR, deliver feedback as a single consolidated GitHub review using /inline-pr-comments. Each run produces a separate review — nothing is overwritten.
- Fetch prior reviews first — the
/inline-pr-commentsskill fetches existing reviews/comments so you can avoid duplicating feedback and stay aware of ongoing discussions - Review body — Overall assessment, architecture concerns, and issues found outside the diff
- Inline comments — Specific issues on changed lines (attached to the same review)
For Self-Review
When reviewing your own changes before committing:
- Run
git diffto see changes - Apply the code review guidelines
- Fix issues directly rather than commenting
Security issues should use /claude-security-review or /claude-tob-review instead.
