What problem does it solve? Designing consistent, accessible interfaces across platforms requires expertise in design systems, user research, and WCAG standards that many teams lack. This Skill provides structured UI/UX guidance covering design tokens, component libraries, user research, and accessibility compliance. ## Core Features & Use Cases - Design System Architecture: Build token-based design systems with atomic design methodology, multi-brand support, and design-to-development handoff workflows. - User Research & Validation: Plan usability tests, user interviews, A/B tests, and journey mapping to validate design decisions with data. - Accessibility & Inclusive Design: Apply WCAG 2.1/2.2 AA/AAA compliance, color contrast analysis, and keyboard navigation patterns from the concept stage. - Use Case: A product team redesigning a B2B dashboard can use this Skill to create a design token architecture, audit accessibility issues, and produce developer-ready component documentation. ## Quick Start Ask the assistant to design an accessible component library with design tokens for a cross-platform web and mobile product.
