What problem does it solve? Users of the caveman skill family often forget the available slash commands, mode names, and deactivation triggers, forcing them to hunt through documentation mid-session. ## Core Features & Use Cases - One-Shot Reference Card: Prints all caveman modes (lite, full, ultra, wenyan variants), sibling skills, and deactivation triggers in a single display. - Non-Persistent Display: Shows help without changing the active mode, writing flag files, or persisting any state. - Configuration Guidance: Explains how to set the default mode via the CAVEMAN_DEFAULT_MODE environment variable or a JSON config file. - Use Case: You are mid-session in caveman mode and forget how to switch to ultra compression or disable auto-activation; invoke the help card to see every command instantly. ## Quick Start Ask the assistant to show the caveman help reference card to list all available modes and commands.
