Claude Code mod
house-rules
Your homelab conventions as rules on Claude's tool calls: a note, an ask or a refusal when a call breaks one (Unraid appdata paths, CLAUDE.local.md staged, force-push to upstream, HA restarts). /rules lists them with hit counts; /rules add makes your own.
Install
/plugin marketplace add davidcoulson/crab-workshop
/plugin install house-rules@crab-workshopMods install like plugins. Run /reload-plugins or start a new session to load it.

How Claude Code mods work
- A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
- It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
- Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
- Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.
