What problem does it solve? After code ships, project documentation drifts out of sync with reality. This Skill audits README, ARCHITECTURE, CONTRIBUTING, CHANGELOG, and other docs against the actual diff, fixing stale claims and surfacing documentation debt before users hit it. ## Core Features & Use Cases - Diff-driven doc audit: Cross-references every documentation file against the branch diff, auto-applying factual fixes and asking before narrative changes. - Diataxis coverage map: Builds a reference/how-to/tutorial/explanation coverage matrix for shipped features and reports gaps as documentation debt in the PR body. - CHANGELOG voice polish and VERSION handling: Scores CHANGELOG entries with a sell-test rubric without rewriting them, and gates any VERSION bump behind explicit user approval. - Use Case: After merging a feature branch, run the Skill to update the README feature table, polish the CHANGELOG entry, clean up completed TODOS, and push a single docs commit with an updated PR body. ## Quick Start Ask the AI to update the project documentation to match what shipped on this branch.
