Agent Skills for Code Review.
These skills follow the Agent Skills specification so they can be used by any skills-compatible agent, including Claude Code and Codex CLI.
Quick Start
Review a GitHub PR with a single command:
Review PR 123
Review PR owner/repo#123
Review PR https://github.com/owner/repo/pull/123
This will automatically:
- Fetch the PR diff from GitHub
- Triage and assess risk
- Run appropriate specialist reviews
- Post the review to GitHub
Overview
This plugin provides a comprehensive code review system modeled after industry-leading tools like CodeRabbit, Cursor BugBot, and Greptile. It uses an Input → Orchestrator → Specialists → Output pipeline architecture:
