I have found that scripts, and the environment that runs them, are the skills' superpower.

Computability (scripts) means being able build documents, access remote data, retrieve data from packaged databases and a bunch of other fundamentally useful things, not just "code things". Computability makes up for many of the LLM's weaknesses and gives it autonomy to perform tasks independently.

On top of that, we can provide the documentation and examples in the skill that help the LLM execute computability effectively.

And if the LLM gets hung up on something while executing the skill, we can ask it why and then have it write better documentation or examples for a new skill version. So skills can self-improve.

It's still so early. We need better packaging, distribution, version control, sharing, composability.

But there's definitely something simple, elegant, and effective here.
