Thanks for sharing this hunt. For me as a full-time web engineer, I can say that there are a lot of this frameworks that provide the groundwork for your UI components. And for this service I'm missing some clean documentation. And I'm also missing some information for your hunt here, just these three sentences? You should describe more how it works and maybe also give an example. :)

Pros:

• Provides a way to create a living styleguide for your UI components

Cons:

• Lacks proper documentation
