skillusage

Skill / slash-command usage analytics for Claude Code and Codex, parsed from your local on-disk data.

[ccusage](https://github.com/ccusage/ccusage) tells you what your agents **cost**. `skillusage` tells you what they **do**: which of your skills actually get used, how often, by you or by the agent itself.
