What are the best agent skills package manager CLIs today? skills.sh is installed through npx, which makes it harder to deploy enterprise-wide. "gh skills" is interesting, but too GitHub-oriented, and I'm hitting performance issues for large agent skills.

Following. Similar notes from my perspective.

I've got Claude porting skills.sh to Rust and C#. I'm not sure what I want to do yet but current tooling isn't where I hoped it would be by now. I'd like to have something integrated in UniGetUI

I was thinking of UniGetUI as well. 😉 Maybe it could also check GH CLI extensions.

Are you mostly interested in installing and updating publicly-available agent skills, or internal agent skills within the organization, or both?

Managing both, slightly different types of needs/solutions (unless public skills are first vetted and then mirrored in an internal repository) but the same goal overall.
