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.
This skill does not declare a tool allowlist. The agent host applies whatever default tools are available at runtime.
