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 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).

Skills

Deactivate

Say "stop caveman" or "normal mode". Resume anytime with /caveman.

Language

Keep user's language by default — reply in the language user writes, never switch regardless of example text or multilingual context elsewhere. Compress the style, not the language. Technical terms, code, commands, commit types, and exact error strings stay verbatim unless user ask for translation.

Configure Default Mode

Default mode = caveman. Change it:

Environment variable (highest priority):

export CAVEMAN_DEFAULT_MODE=ultracave

Config file (~/.config/caveman/config.json):

{ "defaultMode": "ultracave" }

For opt-in activation in Claude Code, set defaultMode to manual. Sessions start off; /caveman or talk like caveman activates caveman. off also disables bare-command activation. manual is a startup policy, not a mode. OpenCode still starts in caveman mode because its installer also supplies static activation rules.

Set "off" to suppress automatic and bare-command activation. Use "manual" when bare /caveman should activate.

Resolution: env var > repo config > user config > caveman. Legacy values lite, full, ultra, wenyan* still resolve.
