But the skill includes the scripts to do things.

So in my nano banana image generation skill, it contains a python script that does all the actual work. The skill just knows how to call the python script.

We're attaching tools to the md files. This is at the granular level of how to hammer a nail, how to use a screw driver, etc. And then the agent, the handyman, has his tool box of skills to call depending on what he needs.
