CLAUDE.md Refresh Skill

Purpose

Intelligently merge updates from the CC Commander template into an existing CLAUDE.md file without destroying user customizations.

Algorithm

1. Parse existing CLAUDE.md into sections (split on ## headers)
2. Parse latest template into sections
3. Classify each section:
   • MATCH: exists in both -> compare content, flag if template is newer
   • MISSING: in template but not in existing -> recommend adding
   • CUSTOM: in existing but not in template -> preserve untouched
4. Generate merge plan showing adds, updates, and preserves
5. Apply after confirmation — insert new sections, update outdated ones, keep custom
