# AI use cases for Caveman (JuliusBrussee/caveman)

Repo: [JuliusBrussee/caveman](https://github.com/JuliusBrussee/caveman) | Use cases: 3 | Page: https://dedupedai.com/use-cases/juliusbrussee-caveman/

Caveman is a skill and proxy for coding agents that cuts tokens by making the agent talk tersely and read less, while code stays exact. The README reports 33.2% fewer input tokens across 54 Claude Code runs and links an Adobe Research paper on caveman-style output; it also links a page listing every case where caveman loses. It installs as a skill, a Claude Code plugin, a Gemini CLI extension or an all-agents installer, with an optional free Auto model router.

This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL.

## How to cut your coding agent's token use with one skill with Caveman

Repo: [JuliusBrussee/caveman](https://github.com/JuliusBrussee/caveman) | Difficulty: Beginner | Time: 5 minutes | Basis: From the README

Install the Caveman skill so the agent answers in short, exact sentences.

**Who it is for:** A developer whose agent writes three paragraphs where one line would do.

**The problem:** Verbose agent replies burn tokens and bury the answer.

**The outcome:** Shorter replies with the same code, switched on and off by command.

### Steps

1. Install for every agent with `npx skills add JuliusBrussee/caveman -g`
2. Or in Claude Code: `/plugin marketplace add JuliusBrussee/caveman` then `/plugin install caveman@caveman`
3. Type `/caveman` (`$caveman` in Codex) if it does not start on its own; `/ultracave` is even shorter
4. Say `stop caveman` to go back to normal

### Prompt to paste into your agent

```text
Install JuliusBrussee/caveman as a skill for my coding agent, run the same task <task> once with and once without it, and compare output tokens and whether the code changes were identical.
```

### Caveat

If you pay per request rather than per token (for example GitHub Copilot), shorter answers save nothing, as the README notes.

## How to shrink what your agent reads: logs, test output and web pages with Caveman

Repo: [JuliusBrussee/caveman](https://github.com/JuliusBrussee/caveman) | Difficulty: Beginner | Time: 15 minutes | Basis: From the README

Turn on the read-less rocks so tool output and pages come back compressed before they hit the context.

**Who it is for:** Someone whose agent context fills up with test logs and HTML.

**The problem:** Long command output and pages eat the context window and push out what matters.

**The outcome:** Fewer input tokens per session, with `caveman status` showing what is active.

### Steps

1. Install with `npx @caveman-ai/cli@latest`
2. Check what is on with `caveman status`
3. Turn a feature off if it gets in the way, for example `caveman off browse`
4. Compare session token counts before and after

### Prompt to paste into your agent

```text
Set up JuliusBrussee/caveman's CLI, show me caveman status, and measure input tokens for one full test-fix loop on this repo with and without it.
```

## How to add Caveman to Gemini CLI as an extension with Caveman

Repo: [JuliusBrussee/caveman](https://github.com/JuliusBrussee/caveman) | Difficulty: Beginner | Time: 5 minutes | Basis: From the README

Install the Gemini CLI extension so the same terse mode works there.

**Who it is for:** A Gemini CLI user who wants the same savings as Claude Code users.

**The problem:** Each agent needs its own install path for skills.

**The outcome:** Caveman mode available inside Gemini CLI.

### Steps

1. Run `gemini extensions install https://github.com/JuliusBrussee/caveman`
2. Start gemini and type `/caveman`
3. Say `stop caveman` to turn it off

### Prompt to paste into your agent

```text
Install JuliusBrussee/caveman as a Gemini CLI extension, confirm /caveman works, and tell me how to uninstall it.
```
