Is there a way to have a UX QA AI with keen eye to design?

Hi all! As many of you, I jumped on the vibe coding train hard. The first prompt is always so promising then the quality deteriorates as the complexity of what you're trying to build increases. The issue I am finding is that there is no clear feedback loop for any agent to get updated prompts related to the UX itself (similar to what a human QA with keen attention to details would be able to see). Has anyone found a tool that can close that feedback loop? I had heard about Playwright and I have been using it but it is not effective. I would appreciate the help. Thanks!
