Installation Guide

Caveman come in two sizes.

Small rock: the skill. A rule file that makes your agent answer in caveman. MIT, free forever, works in [30+ agents](./INSTALL.md) (Claude Code, Codex, Gemini, Cursor, Windsurf, Cline, Copilot, more). One command:

bash
npx skills add JuliusBrussee/caveman

Type /caveman if your agent doesn't wake up on its own. That the whole install. One rock.

Big rock: the proxy. Runs on your machine, between your agent and the AI provider, and shrinks what the agent *reads* before every call. Everything it squeezes gets a backup on your disk, so the agent can always pull the original back. MIT CLI, BSL-1.1 runtime:

bash
npm install -g @caveman-ai/cli && caveman setup --install
caveman claude        # or codex · gemini · aider · kilo · qwen · opencode · hermes · openclaw · pi

They stack. Most people start with the small rock and graduate.

The full installer wires up Claude Code hooks and the statusline badge, finds every supported agent on your machine, and skips agents you no have. Safe to re-run. Needs Node.js 22.13+.

bash
curl -fsSL https://raw.githubusercontent.com/JuliusBrussee/caveman/v2.6.0/install.sh | bash

Windows, PowerShell 5.1+:

powershell
irm https://raw.githubusercontent.com/JuliusBrussee/caveman/v2.6.0/install.ps1 | iex

Just one agent:

bash
# Claude Code
claude plugin marketplace add JuliusBrussee/caveman && claude plugin install caveman@caveman

# Gemini CLI
gemini extensions install https://github.com/JuliusBrussee/caveman

# Qwen Code CLI, then its Caveman wrapper
npm i -g @qwen-code/qwen-code
caveman qwen

# Codex, Cursor, Windsurf, Cline, and other skills-compatible agents
npx skills add JuliusBrussee/caveman --skill '*' -a codex --yes  # replace codex with your agent profile

Install broke? Open your agent in this repo and say: *"Read CLAUDE.md and INSTALL.md, install caveman for me."* Agent read repo, agent fix own brain. Snake eat tail.

Changed your mind: npx -y github:JuliusBrussee/caveman -- --uninstall

The full 30+ agent matrix, dry runs, flags, and verification live in [INSTALL.md](./INSTALL.md).
