What problem does it solve? Reviewing an existing GitHub PR requires gathering its description, prior discussion, and diff context before any meaningful code review can happen. This Skill automates that setup so the review runs against the correct merge-base with full context. ## Core Features & Use Cases - PR Context Fetching: Pulls the PR title, description, prior comments, and base/head branches via the GitHub CLI. - Safe Checkout Handling: Clones the repo to /tmp and checks out the PR there, never switching the branch of the shared working checkout. - Merge-Base Code Review: Delegates to the code-review workflow using the PR's base branch as the fixed point and its description as the spec, passing prior review discussion so settled points are not relitigated. - Use Case: A teammate asks you to review PR #42. The Skill fetches the PR, checks it out in an isolated clone, and produces a structured review where every finding is framed as the author's call. ## Quick Start Ask the agent to review PR 42 and it will fetch the PR, check it out safely, and deliver a full code review against its merge-base.
