Update CLAUDE.md with minimal, concise, targeted edits. Avoid bloat.TRIGGERS - Use this skill when user says:- "update claude.md", "update the claude md"- "sync claude.md", "refresh claude.md"- "edit claude.md", "modify claude.md"- "add to claude.md", "change claude.md"- "update claude.md with X" (explicit content)- Any request to make changes to CLAUDE.md contentTWO MODES:(1) DEFAULT MODE - "update claude.md" → Analyze git changes since last timestamp(2) EXPLICIT MODE - "update claude.md with X" → Add the specific content XCORE PRINCIPLE: Every update must be minimal and concise. Question every line added.Also use when:- User asks to sync CLAUDE.md with recent code changes (default mode)- Adding major dependencies, architecture patterns, or directory changes- Claude repeatedly makes mistakes that a targeted rule could prevent- Post-milestone updates (new APIs, testing patterns, security fixes)- Project standards, workflows, or conventions change
