What problem does it solve? After shipping code, project docs (README, ARCHITECTURE, CONTRIBUTING, CHANGELOG, TODOS) drift out of sync with what actually shipped. This Skill audits every doc against the release diff and brings them back into alignment. ## Core Features & Use Cases - Per-file documentation audit: Cross-references README, ARCHITECTURE, CONTRIBUTING, and CLAUDE.md against the git diff, classifying fixes as auto-updates or user-approved changes. - Diataxis coverage map: Builds a reference/how-to/tutorial/explanation coverage matrix for shipped features and surfaces documentation debt in the PR body. - CHANGELOG voice polish and VERSION bump: Scores CHANGELOG entries with a sell-test rubric without clobbering existing content, and asks before bumping VERSION. - Use Case: After merging a feature branch, run this Skill to update all docs, clean up TODOS.md, sync the PR title with the version, and commit the documentation changes. ## Quick Start Update the docs to match what shipped on this branch and surface any documentation debt in the PR body.
