What is Caveman?

Caveman is a skill/plugin for Claude code, Codex, Gemini, Cursor, Windsurf, Cline, Copilot, and 30+ other agents. Install once. Agent drops the filler and answers in tight caveman-speak, keeping code, commands, and errors byte-for-byte exact. You save output tokens on every reply, forever.

Above is a screenshot from the Caveman README file. It demonstrates how the output tokens can be saved by using less words.

Caveman no make brain smaller. Caveman make mouth smaller. Shrinks what the agent says, not what it knows.

Setup

In the install section, I found the below command

# macOS · Linux · WSL · Git Bash
curl -fsSL https://raw.githubusercontent.com/JuliusBrussee/caveman/main/install.sh | bash

When you run this command, caveman finds every agent on your machine and installs for each of them.

okay what happens after you run this command? In the README, it is mentioned as shown below:

Turn it on: type /caveman or say "talk like caveman". Turn it off: say "normal mode". On Claude Code, Codex, and Gemini it's already on from message one. No command needed.

Wait, there is also modes to this:
