Honestly this thing is so simple that if you have a use case for scheduling CC, it is probably easier to just use it vs. read about it:

pip install claun-tui

I needed a way to quickly (like 60 seconds) get a Claude Code job set up to repeat at an interval. I figured I would save everyone else the tokens and open source it. I've spent many years shipping products that need bulletproof data pipelines, and I understand it would be cleaner and more reliable to use systemd, or a managed tool like AWS Glue. But this is fast, and helps keep the decision loop tight during early stage development.
