Happy pi.dev user here, give it a try! I would say that's kind of the "vim experience" but for harnesses: has the minimum, if you want something more you extend it :)
as is always the answer when this comes up about anything agent related :
save yourself the time and have the agent do it. Don't spend hours on something you don't want to do that it can - that's the point here.
(Edit sorry forgetting names, I mean who's going to buy Earendil). Good luck to Armin, he's done some good stuff.
edit: From first glance, it doesn't look like it. But I basically don't trust any tech company that takes to Tolkien naming conventions.
Sounds like it is not related
