Garbage collection for your Claude Code configuration. Periodically scans ~/.claude (skills, memory, hooks, permissions, MCP servers, caches) for redundant, stale, orphaned, or low-value items, then walks the user through a confirm-each-deletion cleanup. Use when the user says "clean up my config", "config GC", "too many skills", "audit my setup", "my .claude is bloated", or asks for a periodic config review.

# Config GC — Garbage Collection for Claude Code Setups

Borrowed from runtime garbage collection: periodically scan for objects that are no longer referenced, redundant, expired, or low-value, and reclaim the space. The critical difference: **here, collection requires a human in the loop. Never delete autonomously.**

## When to Activate

- The user asks to clean up, audit, or slim down their Claude Code configuration
- The user complains about too many skills, noisy hooks, or slow session startup
- A monthly/periodic config review is due
- After installing a large skill pack (e.g. this repo), to reconcile overlaps with existing setup

Do NOT activate for: cleaning project source code (that's refactoring), clearing chat history, or uninstalling Claude Code itself.
