I like his still of prompt creation "Give me a list of styles to choose from" then choosing one of the available options. SKILL.md files seem to be built upon assumptions of what the language model already knows and understands. Can it be that most skills are therefore tied to a particular LLM vendor/version combination ? The same prompt might be interpreted completely differently by a slightly different language model.

Here the author is asking the machine about what it knows, so there is less of an element of doubt.
