# caveman-stats

> Claude/Codex skill by [@juliusbrussee](https://omgskills.com/library/juliusbrussee/index.md) · 95k stars · Updated 2026-07-26

Show real token usage and estimated savings for the current session. Reads directly from the Claude Code session log — no AI estimation. Triggers on /caveman-stats. Output is injected by the mode-tracker hook; the model itself does not compute the numbers.

## Install

```sh
git clone https://github.com/JuliusBrussee/caveman /tmp/caveman && ln -s /tmp/caveman/skills/caveman-stats ~/.claude/skills/caveman-stats
```

## From README

This skill is delivered by hooks/caveman-stats.js (read by hooks/caveman-mode-tracker.js on /caveman-stats). The model does not need to do anything when this skill fires — the hook returns decision: "block" with the formatted stats as the reason. The user sees the numbers immediately.
