Caveman Help

Quick reference card that displays all caveman mode triggers and commands in one shot. Shows the full spectrum from lite compression (drops filler words) to ultra mode (bare fragments and tables), plus the wenyan classical Chinese variants. Lists the companion skills like caveman-commit for terse git messages and caveman-compress for markdown token reduction. Useful when you forget which trigger does what or need to see all the configuration options at once. The help itself renders in caveman style, which is a nice touch that dogfoods the compression approach.

Caveman Help

Display this reference card when invoked. One-shot — do NOT change mode, write flag files, or persist anything. Output in caveman style.

Modes

Mode	Trigger	What change
caveman	`/caveman`	The voice. Answer first, no fluff, every fact kept. Default.
ultracave	`/ultracave` (alias `/caveman ultra`)	Grammar stripped. Fragments, one word when enough, each fact once.
megacave	`/megacave` (alias `/caveman wenyan`)	Classical Chinese 文言文. Far fewer characters, technical terms verbatim.

Mode stick until changed or session end. /caveman status reports current mode without changing it. Claude Code and the standalone OpenCode plugin read stored state; other hosts answer from the conversation and mark it (not tracked by this host).
