What problem does it solve? Reviewing a code change without context is slow and error-prone. This Skill turns an LLM into a guided review companion that orients you on a change's intent, walks you through its design concerns, surfaces high-risk spots, and suggests how to observe the behavior before you approve or reject it. ## Core Features & Use Cases - Structured Review Trail: Identifies the change from a PR, commit, branch, or spec, computes diff statistics, and builds an ordered review trail of concerns with clickable path:line stops. - Risk and Detail Pass: Scans the diff for risk-sensitive patterns (auth, schema, billing, security, config) and surfaces machine-hardening findings from spec change logs. - Experiential Testing Suggestions: Proposes concrete manual actions and expected outcomes so reviewers can observe the change's behavior directly. - Use Case: After a teammate opens a PR touching authentication middleware, trigger the checkpoint workflow to get an intent summary, a concern-grouped walkthrough, a list of auth and security risk spots, and manual verification steps before approving. ## Quick Start Say "checkpoint" or "walk me through this change" to start a guided human review of the current PR, commit, or branch.
