caveman-stats
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.
Why this skill is useful
Provides real-time token usage statistics and estimated savings directly from session logs, which the AI cannot infer on its own.
What it needs
Requires node installed locally. About 1k tokens when loaded. Last updated 2026-08-07. 405 stars on the source repository.
What this skill does
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.
How to use it
Reference it in AdaL, Claude Code, Cursor or any coding agent — nothing to install:
