GitHub PR Review Skill

Purpose

This skill extracts comprehensive GitHub Pull Request data and provides a structured methodology for code review. It fetches PR metadata, commits, comments, reviews, file changes, and diffs via the GitHub API, then guides analysis across code quality, security, testing, and best practices.

When to Use

Use this skill when you need to:

  • Review a GitHub Pull Request
  • Extract detailed PR information for analysis
  • Generate a comprehensive PR summary
  • Provide structured code review feedback

Prerequisites

Required Tools

  • curl - for GitHub API requests
  • jq - for JSON parsing
  • git - for repository operations

Environment

  • GITHUB_TOKEN - GitHub personal access token (optional for public repos, required for private)

Usage

Via Agent (Recommended)

Use the pr-reviewer agent for context isolation:

/​review-pr https://github.com/owner/repo/pull/123

Direct Skill Invocation

Follow the instructions in instructions.md:

  1. Run extraction:
$HOME/​.claude/​skills/​github-pr-review/​scripts/​extract.sh \
  --owner <owner> --repo <repo> --pr <number>

  1. Read the generated extract.md from the output directory

  2. Apply the review methodology from instructions.md

  3. Save the review to review.md in the same directory

Output

The skill creates a directory structure for each PR review:

$BRAIN_HOME/​github-pr-reviews/​{owner}/​{repo}/​pr-{number}/
├── extract.md    # Raw PR data from GitHub API
└── review.md     # Structured analysis with summary, findings, and verdict

This organization:

  • Keeps all PR reviews in a central location
  • Preserves review history for future reference
  • Groups reviews by repository for easy navigation

Integration

  • Agent: agents/​pr-reviewer.md - runs skill in isolated context
  • Command: commands/​review-pr.md - invokes the agent
