S UI Check

Review how the output communicates and supports its intended use. Judge hierarchy, legibility, labels, visual relationships and navigation or interaction where present. Apply the relevant design system, template or host-product conventions.

Inspect the output in its delivered medium and viewing conditions. Source alone cannot prove appearance, interaction, accessibility or medium fit. Use a renderer or viewer appropriate to that medium and retain rendered evidence; exercise interaction where the output supports it.

Independent verification starts in a fresh context with the accepted contract, candidate identity, and relevant project constraints, without inherited builder conversation or rationale. A review performed in the builder's context remains self-verification.

Treat the project's design system as the source of truth. When none exists, verify coherent reusable visual conventions appropriate to the surface.

Exercise the relevant combinations of:

• light, dark, and system appearance;
• representative wide and narrow layouts, orientation, zoom, and content density;
• keyboard, focus, pointer, touch, assistive names, contrast, and reduced motion;
• loading, empty, validation, saving, success, failure, offline, permission, and destructive-confirmation states that can occur;
• long translated text, dynamic values, overflow, and RTL when localization is applicable or future support is an accepted design constraint;
• platform navigation and interaction conventions, hierarchy, continuity, and recovery from errors.
