What problem does it solve? Keeping local copies of Claude Code official documentation up to date is tedious: you must manually check the GitHub CHANGELOG, figure out which versions you missed, and edit each guide file by hand. This Skill automates that entire sync workflow with version tracking. ## Core Features & Use Cases - Dual version tracking: Separately tracks the cached CHANGELOG version and the version your guide documents actually reflect, so it knows exactly what is missing. - Categorized change analysis: Classifies CHANGELOG entries by topic (Skills, Subagents, CLAUDE.md, Rules, Plugins, Hooks, Breaking Changes) and maps them to the correct guide file. - Safe updates with reporting: Updates the five guide documents under 30-knowledge/37-claude-code/37.00-official-docs/, highlights Breaking Changes, checks whether workspace skills/agents are affected, and never commits to git automatically. - Use Case: You return to your workspace after a month and say "문서 업데이트 확인해줘" — the Skill fetches the latest CHANGELOG, detects three missed versions, updates the affected guides, and reports one Breaking Change requiring manual review. ## Quick Start Ask Claude to check for Claude Code documentation updates and sync the official docs guides.
