Agent Skills: ui-critique

Critique a rendered UI for visual hierarchy, clutter, "AI-generated" tells, and drift from an established design world — when there is no golden image to match against, only a sense that "it looks off / too busy / too AI". Renders the real pixels (headless browser screenshot), judges against a named failure-mode taxonomy, and returns ranked, subtraction-biased fixes that preserve the world. Triggered by "review this UI", "this screen looks cluttered/AI-ish", "critique this design", "why does this feel off", "keep the vibe but clean it up".
