Surgical Code Review

Review diffs in priority order — correctness, then security, then design, then style — with explicit severity labels on every comment.

Use when: Use when asked to review a pull request, a diff, or uncommitted changes and produce actionable feedback rather than a vague approval.

Security Review Checklist

A concrete checklist for reviewing changes against injection, authorization gaps, secret leakage, and unsafe deserialization before they merge.

Use when: Use when reviewing a diff that touches input handling, authentication, database access, file paths, or external calls, or when explicitly asked for a security review.

PR Description Writer

Turn a branch diff into a reviewable pull request description: what changed, why, how it was tested, with risks and review guidance called out.

Use when: Use when opening a pull request or when an existing PR description leaves reviewers to reverse-engineer intent from the diff.
