Type /caveman-stats and get instant token counts and savings for your current session. Unlike most monitoring tools, this reads straight from the Claude Code session log instead of making the AI estimate usage. The hook blocks the command and injects the numbers directly, so the model never even sees the request. Useful when you're curious whether caveman mode is actually saving you tokens or if you're burning through your budget faster than you thought. No guesswork, just the raw numbers from your session.
