What problem does it solve? After a release, documentation often drifts out of sync with the code. This Skill determines exactly which source files changed in a release range and updates only the documentation affected by those changes, avoiding unnecessary rewrites and missed updates. ## Core Features & Use Cases - Diff-driven doc sync: Runs git diff over a release range (auto-detected from tags or a ship artifact) and maps changed source files to documentation via docs-map.yaml, frontmatter sources, or name heuristics. - Changelog verification: Confirms CHANGELOG.md contains an entry for the release without modifying it, since changelog ownership belongs to the ship workflow. - Documentation debt detection: Identifies changed source files with no mapped documentation and reports them as informational debt. - Use Case: After tagging v1.2.0, run the skill to update only the docs whose source modules changed since v1.1.0, with an evidence trail linking every doc claim to a source file and line. ## Quick Start Run the release-docs skill to sync documentation for the latest release range, optionally passing an explicit git range or --dry-run to preview changes.
