Yes you can use this with any text file format and file extension. Markdown just happens to work well with Claude Code and is very readable. But some other comments here mention `.ag` as a nice alternative, and plain text with C code. But you can also use it to send yaml, xml, simple text, or commented code in directly.

The scripts are all pretty simple but they also:

- Handle script-context-relevant flags and control code execution permissions

- Convenience flags for directing scripts to run across cloud providers rather than a personal Claude subscription.

- Session isolation, especially between your regular interactive `claude` command and running with API keys

This means that your runnable script use can be kept isolated from your regular personal Claude environment that you use for interactive development.
