I think Skills could turn into something like open source libraries: standardized solutions to common problems, often written by experts.

Imagine having Skills available that implements authentication systems, multi-tenancy, etc.. in your codebase without having to know all the details about how to do this securely and correctly. This would probably boost code quality a lot and prevent insecure/buggy vibe coded products.

And then you make a global index of those skills available to models, where they can search for an appropriate skill on demand, then download and use them automatically.

A lot of the things we want continuous learning for can actually be provided by the ability to obtain skills on the fly.
