I find it amazing that skills are essentially excellent tools for humans to understand too.

I really wish they were called lessons instead of skills. It makes way more sense and prevents the overloading of the term "skill".

There is some papers [0] showing that the skill and agent files reduce the reasoning effectiveness in some use cases (e.g. autogenerated)

We'd just be overloading "lessons" as well, and even more so because it takes more work to ground the concept, given its larger semantic distance from what we're describing.
