What's the biggest UX mistake AI tools make when generating interfaces?

I've been building a Claude Code plugin that tries to solve this — and I'd love to hear what frustrates you most.

For me, the top offenders are:

- Same generic fonts (Inter, Roboto) on every project regardless of context

- Purple gradients on white backgrounds (the "AI aesthetic")

- Jumping straight to code without understanding the product

- No iteration — you get V1 and that's it

I compiled 376 UX rules from WCAG 2.1, Nielsen Norman, and Laws of UX into a plugin that asks questions first, then designs with live preview.

Launching tomorrow — curious if others have hit the same wall, and what you'd want a UX co-pilot to actually do differently.
