## About

### What it is

Caveman is a set of tools designed to reduce token consumption by AI agents. It compresses logs, manages agent scripts, and optimizes agent output to lower costs while keeping code and information exact.

### Who it suits

It is for developers and engineers who use AI coding agents and want to manage their token usage.

### Where to use it

You can use it within terminal-based coding agents, CLI tools, and various development frameworks.

- Claude Code
- Gemini CLI
- Codex
- OpenCode
- Vercel AI SDK
- LangChain

### How to set it up

You need a machine running Node.js 22.13 or newer on Mac, Linux, or Windows.

1. Install the CLI using the command provided.
2. Run the tool to automatically find agents and logins.
3. Use the status command to see which features are active.

```bash
npx @caveman-ai/cli@latest
```

### How to use it

You can interact with the tools by running commands in your terminal or by invoking slash commands directly through your agent's chat interface.

```bash
caveman status
```

\| Tool \| What it does \| \|---\|---\| \| /caveman \| Sets the agent to respond with short, direct phrases \| \| /caveman-compress \| Shrinks memory files while keeping the content intact \| \| caveman-blocks \| Manages and reuses common scripts written by agents \| \| caveman login \| Connects to a free account to enable model routing \|

### Example

Instead of a long explanation, the agent provides a direct fix. The answer remains accurate but consumes fewer tokens.

### For newcomers and experts

Newcomers can think of this as a filter that asks the AI to be brief, which saves time and money. Experts can use it as a token-efficiency layer that sits between the agent and the model provider. It uses response-voice control, log-file compression, and script-block reuse to optimize token throughput. It trades off conversational style for structured output that preserves functional integrity.

### Good to know

- The tool operates locally on your machine for most tasks.
- It can read your local files, logs, and agent scripts.
- It is released under the Apache-2.0 license.
- Features like Auto model routing require a free account and may send metadata to the cloud.

It saves tokens. Being polite consumes extra tokens, and being rude can risk you getting banned. So use caveman speak, save tokens.
