What problem does it solve? Reviewing a pull request normally requires having the target project checked out locally with its environment configured. This Skill lets you review any GitHub PR from anywhere on your machine: it clones or reuses the repo, pins the exact PR head commit, runs a best-effort build and test pass, and posts a deduplicated inline review grounded in the project's own rules. ## Core Features & Use Cases - Checkout-free PR review: Accepts a PR URL or owner/repo#N, clones under a global cache keyed by owner/repo, and creates a review worktree pinned to the immutable head SHA. - Project-aware review scope: Detects rule files (CLAUDE.md, AGENTS.md, docs/ai-rules, .cursorrules) and existing automated reviewers (CodeRabbit, SonarQube, linters, CodeQL) to skip categories bots already cover and focus on logical bugs, edge cases, and missing tests. - Evidence-backed findings: Runs setup and tests in the background (Gradle, Maven, Node), classifies each finding as PR-introduced, PR-exposed, or pre-existing, checks author intent, and dedups against existing PR comments before posting. - Use Case: A teammate asks you to review https://github.com/your-org/example-service/pull/356 but you don't have that repo locally. Invoke the Skill with the URL; it clones the service, runs its tests, reviews the diff against the repo's rules, and posts an inline review with suggested fixes. ## Quick Start Ask the AI to run ar-global-pr-reviewer with a full GitHub pull request URL, for example global review https://github.com/your-org/example-service/pull/356.
