What problem does it solve? Large or unfamiliar pull requests are hard to review by reading diffs alone; this Skill builds a visual map of what a PR logically changes and walks a human reviewer through it step by step, keeping the review above line-level code. ## Core Features & Use Cases - Seven-dimension logical review: evaluates intent, architecture, impacts and dependencies, user experience, operational impact, documentation drift, and test story with a traffic-light status per dimension. - Visual dossier: generates Mermaid before/after architecture diagrams and impact maps, persisted in .reviews/prs/ so the review survives session interruptions. - Interactive walkthrough: dispatches parallel scan and zoom subagents, then guides the reviewer through small sections with closed-menu questions, finding triage, and an optional GitHub comment draft approved verbatim before posting. - Use Case: A reviewer facing a 40-file PR asks for a walkthrough, receives a map of the 5 logical changes, triages each finding as real problem, accepted trade-off, or false alarm, and ends with author questions ready to post. ## Quick Start Walk me through PR 142 and build a visual review dossier of what it changes.
