# Caveman Stats

> Caveman Stats is an Agent Skill for productivity published in the JuliusBrussee/caveman repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

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.

## SKILL.md

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.
