What problem does it solve? Reviewing pull requests consistently is hard: reviewers skip verification, miss security risks, or disturb their own working tree while inspecting someone else's branch. This Skill enforces a hard review contract that produces an evidence-based review artifact before merge. ## Core Features & Use Cases - Safe diff inspection: Defaults to remote-diff mode using three-dot git diff (base...head) so the current branch and uncommitted work are never touched; escalates to an isolated external worktree only when runtime verification is needed. - Structured findings: Every finding carries severity (Critical/High/Medium/Low/Info), location, evidence, impact, recommendation, and confidence, plus testing gaps and residual risks. - Merge recommendation taxonomy: Outputs Approve, Approve with comments, Request changes, Needs more info, Needs more verification, or Blocked, with PR description accuracy checked against the actual diff. - Use Case: A teammate opens a PR from branch A into develop. You ask the agent to review it; it fetches refs, diffs origin/develop...origin/A, checks CI status via gh, and writes REVIEW_PR.md with findings and a merge recommendation — without checking out anything. ## Quick Start Ask the agent to review the pull request from branch feature-x into develop and produce the REVIEW_PR.md report with findings and a merge recommendation.
