Nori uses Claude Code's skills extensively, which you can see here: https://github.com/tilework-tech/nori-profiles/tree/main/src...

We use Claude Code's ability to use skills by defining a bunch of really useful and common skills that are necessary for writing software. For e.g. brainstorming, doing test driven development, or submitting a git commit.

The specific skills you linked are interesting demos of what you can do with skills! But most of them are not useful for the day to day of building software
