AI-consumed reference. This skill verifies rendered UI; it does not generate taste (that's frontend-aesthetics) or enforce statically (that's the design-conformance hook + theme-consistency rule). Close the loop: build → see → critique → fix.

Design Vision Loop

Open-loop text guidance is why "correct" UI still looks off — nobody looked at it. This skill adds the eyes: render → screenshot → critique → iterate, the pattern Anthropic endorses for UI agents (Building agents with the Claude Agent SDK: "visual feedback… can be helpful"; computer-use docs: "after each step, take a screenshot and carefully evaluate… only when you confirm a step was executed correctly should you move on").

Precondition

The UI must be renderable: a running dev server URL/route, or a static HTML artifact. If nothing renders (component with no harness), say so and either spin up a preview or fall back to static review — don't pretend to have looked.
