If you're building a React component library and need full control over styling while keeping accessibility rock solid, this is your blueprint. Radix UI gives you unstyled primitives with WAI-ARIA compliance baked in, so you handle the CSS however you want. The skill walks through real patterns: theming with CSS variables or Tailwind, compound components, the asChild polymorphic trick. It's opinionated about composition over configuration and never breaking the accessibility features Radix ships with. Good for design systems or when shadcn feels too prescriptive but you still want the Dialog and Dropdown complexity handled correctly. Won't help if you need something non-React or just want styled components out of the box.
