Install the caveman-help skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description. 

git clone --depth 1 https://github.com/JuliusBrussee/caveman.git /tmp/caveman
mkdir -p ~/.claude/skills
cp -r /tmp/caveman/skills/caveman-help ~/.claude/skills/caveman-help
available in every project

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.

  • Acaveman-commitWrite a Conventional Commits message compressed to intent only. Use for "write a commit", "commit message", /commit or /caveman-commit.
  • Ccaveman-compressCompress a memory file such as CLAUDE.md or a todo list into caveman format to save input tokens, keeping a readable backup. Sends the file's text to the configured model provider. Trigger: /caveman-compress.
  • Ccaveman-compressCompress a memory file such as CLAUDE.md or a todo list into caveman format to save input tokens, keeping a readable backup. Sends the file's text to the configured model provider. Trigger: /caveman-compress.
  • Acaveman-discoverFind and label every LLM workflow in the repository so Caveman Cloud groups spend by workflow instead of one bucket. Use for "discover workflows" or breaking LLM spend down by workflow.
  • Acaveman-evidence-reviewRead-only review of Caveman Cloud evidence: cost, Cave Score, workflows, traces, latency, errors, routing, savings. Use when asked what Caveman found or where LLM spend goes.
  • Acaveman-exploreRead-only repository explorer for cold-start orientation, broad cross-file localization, or when a direct search failed. Skip it when the exact file or symbol is already named. Returns path:line citations only; its reads stay out of main context.
  • Acaveman-learnAct on a Caveman learn report - review the ranked token sinks, apply cost-lowering fixes with per-edit consent, and report what those fixes returned. Use when asked to lower an agent's token cost, what caveman has saved, to trim a heavy CLAUDE.md, or to offload re-pasted context into cavemem.
  • Acaveman-manageInspect Caveman Cloud's experiment lifecycle and block unsafe execution. Use when asked to start, approve, cancel, promote or roll back a Caveman experiment.
