What problem does it solve? Building a consistent design system from scratch requires defining tokens, wiring build configuration, and implementing accessible base components, which is repetitive and error-prone when done manually. ## Core Features & Use Cases - Design Token Generation: Creates color, typography, spacing, shadow, and radius token files plus CSS variable setup for light and dark themes. - Base Component Library: Provides reference implementations of Button, Input, and Card components using class-variance-authority variants and a barrel export index. - Build Integration: Wires tokens into a Tailwind config and supplies the cn class-merge utility built on clsx and tailwind-merge. - Use Case: When starting a new React product, use this Skill to scaffold a token-driven design system with themed CSS variables, a Tailwind theme extension, and documented UI primitives ready for extension. ## Quick Start Generate a design system with brand colors, base Button and Input components, and a Tailwind config for my React project.
