Caveman Stats

The Caveman Stats agent skill provides developers with real-time token usage and estimated cost savings for their current session, directly from the Claude Code session log without AI estimation. This agent skill is particularly valuable for developers and teams using AI agents powered by Claude models who need clear visibility into their session's token consumption and potential cost efficiencies. This is a skill with 2K installs, indicating a notable level of adoption among the agent skill registry. To use it, a developer simply triggers the `/caveman-stats` command within their session. The skill operates via a backend hook, which directly reads session logs and injects the token usage data and savings estimates into the output, meaning the AI model itself does not process the request or compute these statistics, ensuring immediate results without additional token expenditure.
