Does the UI match expected behavior?
It compares implementation against supplied expectations, visible states, and user-facing behavior.
Frontend QA / Design Checker
Frontend QA / Design Checker is the Builder Core AI UI QA checker for interface quality. It reviews expected behavior, responsive layout, accessibility basics, and UI states without pretending a browser pass happened when it did not.
What it answers
It compares implementation against supplied expectations, visible states, and user-facing behavior.
It looks for responsive wrapping, unstable dimensions, overflow, occlusion, and controls that become hard to use.
It separates code review, screenshot review, and live browser verification so the answer does not overclaim.
Good fit
