People are really misunderstanding Skills, in my opinion. It's not really about the .md file. It's about the bundling of code and instructions. Skills assume a code execution environment.

You could already pre-approve an executable and just call that from your prompt. The context savings by adding/indexing metadata and dynamically loading the rest of the content as-needed is the big win here IMHO.

Yes, and! It's the combo/bundling/distribution of these things that makes this powerful.
