How this skill gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Quick-reference card for all caveman modes, skills, and commands.
One-shot display, not a persistent mode. Trigger: /caveman-help,
"caveman help", "what caveman commands", "how do I use caveman".
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 | |------|---------|-------------| | **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. 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` macOS/Linux, `%APPDATA%\caveman\config.json` Windows):
{ "defaultMode": "lite" }Set `"off"` to disable auto-activation on session start. User can still activate manually with `/caveman`.
Resolution: env var > config file > `full`.

Other skills on caveman.
- /cavecrew
Decision guide for delegating to caveman-style subagents. Tells the main thread WHEN to spawn `cavecrew-investigator` (locate code), `cavecrew-builder` (1-2 file edit), or `cavecrew-reviewer` (diff review) instead of doing the work inline or using vanilla `Explore`. Subagent
Open skill - /caveman-compress
Compress natural language memory files (CLAUDE.md, todos, preferences) into caveman format to save input tokens. Preserves all technical substance, code, URLs, and structure. Compressed version overwrites the original file. Human-readable backup saved as FILE.original.md.
Open skill - /caveman-stats
Show real token usage and estimated savings for the current session. Reads directly from the Claude Code session log — no AI estimation. Triggers on /caveman-stats. Output is injected by the mode-tracker hook; the model itself does not compute the numbers.
Open skill - /caveman
Ultra-compressed communication mode. Cuts output tokens 65% (measured) by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like

Open skill - /caveman-commit
Ultra-compressed commit message generator. Cuts noise from commit messages while preserving intent and reasoning. Conventional Commits format. Subject ≤50 chars, body only when "why" isn't obvious. Use when user says "write a commit", "commit message", "generate commit",
