If you ever want a few more features on top of "CC in a container", then do consider byre. It's literally that, but also a nice TUI for adding extra folders, reusable skills, encrypted credentials, etc, and you can eject back to plain Docker (or Podman) whenever you want. Useful if you want to just be able to go to any folder and spin it up with your toolbox with one command: https://github.com/pjlsergeant/byre
