Build accessible design systems with Radix UI primitives. Headless component customization, theming strategies, and compound component patterns for production-grade UI libraries.

Radix UI Design System Build production ready, accessible design systems using Radix UI primitives with full customization control and zero style opinions. Detailed Guide Read [the detailed guide](references/detailed guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end to end work, read the guide completely. When to Use This Skill Creating a custom design system from scratch Building accessible UI component libraries Implementing complex interactive components (Dialog, Dropdown, Tabs, etc.) Migrating from styled component libraries to unstyled primitives Setting up theming systems with CSS variables or Tailwind Need full control over component behavior and styling Building applications requiring WCAG 2.1 AA/AAA compliance Do not use this skill when You need pre styled components out of the box (use shadcn/ui, Mantine, etc.) Building simple static pages without interactivity The project doesn't use React 16.8+ (Radix requires hooks) You need components for frameworks other than React Real World Examples Example 1: Command Palette (Combo Dialog) Example 2: Dropdown Menu with Icons Example 3: Form with Radix Select + React Hook Form Limitations Use this skill only when the task clearly matches the scope described above. Do not treat the output as a substitute for environment specific validation, testing, or expert review. Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
