What problem does it solve? Diff-only reviews miss whether code actually builds, runs, and behaves as claimed. This Skill checks out a pull request into an isolated git worktree, runs the project's build and tests, and then audits the change across a fixed set of review lenses so findings are grounded in real behavior. ## Core Features & Use Cases - Run-before-review workflow: Checks out the PR with gh pr checkout or a detached worktree, installs dependencies, runs the test suite, and exercises the changed code path before judging it. - Fixed audit lenses: Evaluates AI slop, obvious bugs, test quality, code and file structure, implementation correctness, docs consistency, and whether the PR should be split into a stack. - Headless mode: Supports a --headless flag for automated orchestration that posts the full report as a PR comment via gh pr comment without interactive prompts. - Use Case: A teammate asks you to review PR #123 before merge. The Skill checks it out, runs the suite, finds a broken error path the diff hid, and reports findings with file:line references ordered by severity. ## Quick Start Ask the assistant to review pull request number 123 and it will check out the branch, run it, and produce a structured review report.
