SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you review GitHub pull requests and local diffs quickly and consistently, turning changes into clear, prioritized feedback before code is merged.

Core Features & Use Cases

  • Diff-based code review for local changes: Use staged diffs or comparisons (e.g., against main) to find issues and summarize findings.
  • PR-level review workflow on GitHub: View PR details, inspect diffs and changed files, and leave summary plus inline comments.
  • Formal review submission with appropriate verdicts: Approve, request changes, or comment using either gh or REST API calls.

Use it when preparing for a pre-push review of new code, performing an end-to-end PR review (including inline notes), or creating a checklist-driven review that maps findings into Critical / Warning / Suggestion / Looks Good.

Quick Start

Have your agent review PR number 123 on GitHub and return a structured summary with prioritized Critical, Warning, Suggestions, and Looks Good sections.
