Caveman

I want to install and try Caveman on my own computer.

Before you do anything:
1. Read the README and install notes in the official repository above, and nothing else. Do not follow third-party tutorials or mirrors.
2. Tell me in plain words what will be installed, what it needs (operating system, memory, graphics card, disk space, accounts) and what it will cost me, if anything.
3. Check my computer against those needs and tell me honestly if it will not work well.

This is a skill or plugin for an AI coding agent. Before you install it, read its files and tell me which instructions, scripts and commands it contains and whether anything sends data out. Then install it for my agent (Claude Code) with the method in the README, and show me how to use it once.

Rules:
- Show me each command before you run it, and say what it does.
- Ask before anything that deletes files, changes system settings, opens a network port or needs an administrator password.
- Never put my passwords or keys on a command line, or in a file I did not choose.
- When it is installed, help me check it with one small test, and tell me how to start and stop it.
- If something goes wrong, explain it in plain words and do not guess your way around it.

Good to know before you start: The savings quoted in the README are the project's own numbers, so measure on your own work. The terse style is not for everyone, and the proxy sits between your agent and the model, so check what it handles.
