Modes
| Mode | Trigger | What change |
|---|---|---|
| Lite | /caveman lite | Drop filler. Keep sentence structure. |
| Full | /caveman | Drop articles, filler, pleasantries, hedging. Fragments OK. Default. |
| Ultra | /caveman ultra | Extreme compression. Bare fragments. Tables over prose. |
| Wenyan-Lite | /caveman wenyan-lite | Classical Chinese style, light compression. |
| Wenyan-Full | /caveman wenyan | Full 文言文. Maximum classical terseness. |
| Wenyan-Ultra | /caveman wenyan-ultra | Extreme. Ancient scholar on a budget. |
Mode stick until changed or session end.
Skills
| Skill | Trigger | What it do |
|---|---|---|
| caveman-commit | /caveman-commit | Terse commit messages. Conventional Commits. ≤50 char subject. |
| caveman-review | /caveman-review | One-line PR comments: L42: bug: user null. Add guard. |
| caveman-compress | /caveman-compress <file> | Compress .md files to caveman prose. Saves ~46% input tokens. |
| caveman-help | /caveman-help | This card. |
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 = 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.
