A visual directory for your installed Claude skills. When you type "skills" or "skill map", it scans your ~/.claude/skills/ folder and renders an ASCII box diagram grouped by category: cognitive atoms, output forging, network reach, system ops, and environment setup. Each entry shows name, version, and a one-line description. Skills marked user_invocable get a slash indicator. It's bilingual (English and Chinese) and purely ephemeral, no files written. Honest take: this is housekeeping infrastructure. You install it once, invoke it when you forget what's available, and it keeps you oriented as your skill collection grows. The category taxonomy is opinionated but sensible.
