What problem does it solve? Keeping user documentation in sync with a fast-changing codebase is tedious and error-prone. This Skill reviews recent git commits, staged changes, and changelog entries to detect how product behavior actually changed, then updates the docs directory page by page so the documentation always matches the real user experience. ## Core Features & Use Cases - Change-Driven Doc Updates: Reads recent git commits, staged changes, and changelog.md to identify user-facing behavior changes, consulting the actual source code when needed. - Changelog Synchronization: Runs the docs/scripts/sync-changelog.mjs script first to keep the English changelog current before editing content. - Bilingual Documentation Maintenance: Verifies Chinese documentation matches the latest code behavior, then hands off to the translate-docs skill for bilingual synchronization. - Use Case: After merging a feature branch that changes CLI flags, invoke this Skill to audit every affected docs page against the new code and produce consistent, up-to-date English and Chinese documentation. ## Quick Start Update the project documentation to reflect the latest git commits and staged changes, then sync the changelog and translations.
