README

agent-cleaner

Slim down installed Claude Code or Codex skills, Claude Code subagents, and MCP servers based on usage. Reports per-entry last-used time, suggests stale ones, and disables them — by renaming the source file (skills/subagents) or by splicing the entry out of its config and stashing it for restore (MCP servers). After the agent restarts, disabled descriptions and tool catalogs no longer appear in the system prompt — recovering context budget for actual work.

Quick start: Claude Code

git clone  agent-cleaner
cd agent-cleaner

npm install
npm run install:plugin     # build + register + enable

Restart Claude Code. In a new session, ask the model:

帮我瘦身一下 skills

The bundled SKILL guides the model through `suggest` → confirm → `disable`.

Quick start: Codex

git clone  agent-cleaner
cd agent-cleaner

npm install
npm run install:codex-plugin

Restart Codex. Then run the slash command:

/agent-cleaner:skills

That command is backed by `~/.codex/prompts/agent-cleaner-skills.md`. Codex loads Markdown files in `~/.codex/prompts` as slash commands: a file named `agent-cleaner-skills.md` appears as `/agent-cleaner:skills`. The installed prompt tells Codex to call the bundled CLI with `--host=codex`, show suggestions, ask for confirmation, and then disable selected skills.

To remove later:

npm run uninstall:plugin                # Claude Code
npm run uninstall:plugin -- --purge
npm run uninstall:codex-plugin          # Codex
npm run uninstall:codex-plugin -- --purge

⚠ Uninstall does **not** auto-restore disabled skills. If you want them back, run `skills enable ` *before* uninstalling, or just re-install.

CLI

The same bundle is usable directly without going through the agent UI:
