70 / 100 · Review before installing
Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

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.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'config-gc' ] || [ -L ~/.agents/skills/'config-gc' ]; then echo 'A skill folder named config-gc already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/affaan-m/ECC' "$d" && git -C "$d" checkout --quiet 'd2ef2680594f9a17526a6e1a2e18b3d242c5d17b' -- 'skills/config-gc' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/config-gc' ~/.agents/skills/'config-gc' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'config-gc' ~/.claude/skills/'config-gc' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
