What problem does it solve? Reviewing a code change without structure leads to missed risks and shallow approvals. This Skill walks a human reviewer through a change step by step — from understanding its intent, to a concern-organized walkthrough, to risk-spot detection, to hands-on verification — so the review decision is informed rather than rubber-stamped. ## Core Features & Use Cases - Orientation and Intent Summary: Identifies the change from a PR, commit, branch, spec, or sprint status, then summarizes intent and surface-area stats (files changed, modules touched, boundary crossings). - Concern-Based Walkthrough: Groups diff stops by design intent rather than by file, ordered for comprehension with clickable path:line references. - Risk and Testing Passes: Surfaces high-blast-radius spots (auth, schema, billing, security, config) and suggests manual observations of user-visible behavior, ending in an approve/rework/discuss decision. - Use Case: After a teammate opens a PR, ask for a walkthrough — the Skill resolves the diff baseline, builds a review trail, and guides you through each concern before you approve via gh pr review. ## Quick Start Ask the assistant to walk you through the current change or a specific PR, for example by saying "walk me through this change on the current branch".
