I took a peek out of curiosity and MoltHub… wow. Sorting is all done locally and only sorts skills that have been loaded onto the client, so scrolling down inserts skills into their sorted positions rather than at the bottom of the list. Scrolling down to the bottom of what’s been loaded (infinite scroll) can therefore insert stuff to the top of the list.

Also, from what it looks like, skills just execute arbitrary code on your machine. While I’m not surprised, considering one of the most popular skills (from what I can tell) is a Polymarket trader, I’m gonna nope out of that one.
