Basically skills are /commands that can have attached scripts, that's about it.

If your "skill" doesn't come with scripts/executables, it's just a fancy slash command.

I've had success with code quality analysis skills that use PEP723 Python scripts with tree-sitter to actually analyse the code structure as an AST. The script output and switches are specifically optimised for LLM use, no extra fluff - just condensed content with the exact data needed.
