What problem does it solve? AI-generated UI often looks generic, ignores accessibility requirements, and breaks on different screen sizes. This Skill enforces the engineering standards that make interfaces look professionally built: WCAG 2.1 AA accessibility, responsive layouts, proper state handling, and adherence to the project's actual design system. ## Core Features & Use Cases - Component Architecture Guidance: Enforces composition over configuration, colocated file structures, and separation of data fetching from presentation. - Accessibility Compliance: Covers keyboard navigation, ARIA labels, focus management, and meaningful empty/error states to meet WCAG 2.1 AA. - Design System Adherence: Eliminates the recognizable "AI aesthetic" (purple gradients, excessive rounding, stock card grids) in favor of the project's real spacing scale, color tokens, and typography hierarchy. - Use Case: When building a new dashboard page, use this Skill to generate components with skeleton loading states, optimistic updates, mobile-first responsive grids, and full keyboard accessibility instead of a generic template layout. ## Quick Start Ask the agent to build a responsive, accessible task list component with loading, error, and empty states that follows the project's design system.
