disable-model-invocation: true

In Claude Code a hook answers this command without the model; you only see it when that hook
did not run (agy, or an old install). Then:

1. Run `python3 <team skill folder>/scripts/tw.py addons $ARGUMENTS` from the repository
   root and show its output as it is.
2. If the user asked in words ("install caveman", "add the MCP servers"), translate it into
   `addons add <name>` or `addons remove <name>` and run that.
3. Remind the user to restart the app to load the change; in agy, `!team addons`
   does it without spending tokens (after `tw.py install-cli`).
