Deactivate

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

Language

Keep user's language by default. User write Portuguese → reply Portuguese caveman. 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 = full. Change it:

Environment variable (highest priority):

export CAVEMAN_DEFAULT_MODE=ultra

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

{ "defaultMode": "lite" }

Set "off" to disable auto-activation on session start. User can still activate manually with /caveman.

Resolution: env var > config file > full.
