What problem does it solve?
It prevents documentation from drifting out of date by making your project docs accurately reflect the current codebase while safeguarding future-facing planning content.
Core Features & Use Cases
- Codebase-to-docs mirror updates: Refreshes wrong, stale, or obsolete documentation by comparing what exists in the repository against what the docs claim.
- Forward-looking preservation: Never removes roadmaps, visions, open questions, architectural proposals (ADRs/RFCs), or other future-oriented sections; ambiguous items are flagged instead of silently deleted.
- Documentation inventory and gap analysis: Finds documentation across the repo, categorizes freshness/accuracy, and identifies missing or outdated areas.
- Cleanup and consistency: Removes completed TODOs already implemented, deletes dead references, reduces redundancy, and fixes cross-document inconsistencies.
Quick Start
Run /devlyn:update-docs in the repository to synchronize all documentation with the current codebase while preserving any Roadmap, Vision, RFC, Open/TBD, and Phase markers.
