What problem does it solve? Reviewing a code change without guidance is slow and error-prone: reviewers miss the intent behind a diff, overlook high-risk spots, and lack a structured way to verify behavior. This Skill walks a human reviewer through a change step by step, from understanding its purpose to making an approve/rework decision. ## Core Features & Use Cases - Orientation and Intent Summary: Identifies the change from a PR, commit, branch, or spec, then presents the intent and surface-area stats (files changed, modules touched, boundary crossings). - Concern-Based Walkthrough: Organizes the diff by design concerns with clickable path:line stops, generating a review trail automatically when the author did not provide one. - Risk and Testing Passes: Surfaces high-blast-radius spots (auth, schema, billing, security) and suggests concrete manual observations to verify behavior. - Use Case: A teammate opens a PR touching authentication middleware. Trigger the walkthrough to get the intent summary, a guided tour of the key code locations, a list of risk spots like token validation changes, and suggested manual tests before approving. ## Quick Start Ask the assistant to walk me through this change or give me a human review of the current PR.
