What problem does it solve? After shipping code, project documentation (README, ARCHITECTURE, CONTRIBUTING, CHANGELOG, TODOS) often drifts out of sync with what actually shipped. This Skill audits every doc file against the release diff and brings documentation back in line with reality. ## 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-confirmed changes. - Diataxis coverage map: Builds a reference/how-to/tutorial/explanation coverage matrix and surfaces documentation debt in the PR body. - CHANGELOG voice polish: Scores entries with a sell-test rubric and rewrites commit-message-style entries without ever clobbering existing content. - Release hygiene: Cleans up TODOS.md, optionally bumps VERSION, syncs the PR title, and runs an independent Codex or Claude cross-model doc review. - Use Case: After merging a feature branch, run this Skill to update all docs, polish the CHANGELOG, and append a documentation debt summary to the PR body before release. ## Quick Start Update all project documentation to match what shipped on this branch and surface any documentation gaps in the PR body.
