What problem does it solve? AI-generated interfaces often look generic, ignore accessibility requirements, and lack proper loading, error, and empty states. This Skill enforces disciplined component architecture, design system adherence, and WCAG 2.1 AA accessibility so UI output looks professionally engineered rather than machine-generated. ## Core Features & Use Cases - Component Architecture Patterns: Enforces composition over configuration, container/presentation separation, and colocated file structures for React components. - Accessibility Enforcement: Provides concrete patterns for keyboard navigation, ARIA labels, focus management, and meaningful empty/error states meeting WCAG 2.1 AA. - Design System Discipline: Rejects the generic "AI aesthetic" (purple gradients, excessive rounding, stock card grids) in favor of consistent spacing scales, semantic color tokens, and type hierarchy. - Use Case: When asked to build a task management dashboard, the Skill produces a responsive grid with skeleton loading states, optimistic updates via React Query, keyboard-accessible controls, and styling drawn from the project's actual design tokens. ## Quick Start Ask the AI to build a responsive, accessible task list component with loading, error, and empty states using the project's design system.
