What problem does it solve? Commit messages rarely tell the whole story of what a change actually does. This Skill reads the full diff of every commit on a branch or PR, traces each change to its real integration points across layers, and verifies claimed behavior with executable evidence so you know the true blast radius before merging. ## Core Features & Use Cases - Full-Diff Commit Review: Enumerates commits against the real baseline, reads every diff hunk, and identifies which invariants, callers, and behaviors changed. - Cross-Cutting Impact Tracing: Greps every consumer of changed types, protocol kinds, and CSS hooks to catch half-dead features that are emitted but unmapped or mapped but unstyled. - Evidence-Based Verification: Runs the project's real gates (typecheck, JS tests, dotnet build/test) and answers questions like "does X still exist?" by tracing the full stack from model to render to CSS to layout, citing file:line evidence. - Use Case: Before merging a PR that adds a new drag-and-drop target kind, use this Skill to confirm the schema, producer, consumer host, presentation CSS, tests, and contract docs were all updated, and to get real test pass counts instead of trusting the commit message. ## Quick Start Ask the agent to read this branch's commits, analyze what changed and what the impact is, and verify the claims by running the project's test gates.
