Use this skill to review code changes against Hyperlane monorepo standards.
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.
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.
/inline-pr-comments skill fetches existing reviews/comments so you can avoid duplicating feedback and stay aware of ongoing discussionsWhen reviewing your own changes before committing:
git diff to see changesSecurity issues should use /security-review or /tob-review instead.

Write a changeset file in the `hyperlane-registry` repo for a PR that adds, updates, or modifies warp route config / chain metadata / addresses. Canonical pattern — never run the interactive `pnpm changeset` CLI; write the file directly. Referenced by any skill that opens a registry PR.

The low-level on-chain probes for identifying what an owner address is — cast code → EOA / EIP-7702-delegated EOA / contract, VERSION() → Gnosis Safe, read-only get-owner-ica.ts derive → ICA derivation, getAccountInfo → Sealevel account existence — with how to interpret each result. The primitive layer beneath validate-owners / resolve-artifacts / update-owners, which each apply their own per-chain or per-artifact policy on top.
