What problem does it solve? After code is implemented, project documentation often drifts out of sync with reality. This Skill closes the gap by updating SPEC statuses, changelogs, architecture docs, and decision records so the repository always reflects the current state of the codebase. ## Core Features & Use Cases - Documentation Synchronization: Marks SPECs as completed, refreshes API docs, architecture diagrams, and CHANGELOG entries after implementation. - @AX Tag Lifecycle Management: Tracks TODO cycle counters, verifies ANCHOR fan-in reference counts, and removes orphaned NOTE tags across the codebase. - Two-Phase Lore Commits: Splits commits between module repositories and the meta repository with conventional commit messages. - Use Case: After finishing a feature with /auto go, run the sync step to mark SPEC-AUTH-001 completed, update ARCHITECTURE.md, record decisions in Lore, and commit everything in the correct repos. ## Quick Start Ask the agent to run /auto sync SPEC-AUTH-001 to synchronize all project documentation and commit the changes.
