It's not hard to force even the mid tier Chinese models to build a fast, easy to use, reasonably bug free app.

All you need to do is become a UX designer and complain about every small problem you see. That way any bad patterns leaves the repo fast and your agents will repeat the good ones. Pick frameworks with minimal boilerplate and good performance so you don't get lost in syntax noise or end up with Electron slop.

And always read code before you commit, that's the only thing that separates you from a stupid vibe coder.
