Radix UI Design System

Overview

This public intake copy packages

plugins/antigravity-awesome-skills-claude/skills/radix-ui-design-system

https://github.com/sickn33/antigravity-awesome-skills

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses

metadata.json

ORIGIN.md

Radix UI Design System Build production-ready, accessible design systems using Radix UI primitives with full customization control and zero style opinions.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Getting Started, Theming Strategies, Component Patterns, Accessibility Checklist, Performance Optimization, Integration with Popular Tools.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• 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

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
2. Read the overview and provenance files before loading any copied upstream support files.
3. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
4. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
5. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
6. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.
7. Before merge or closure, record what was used, what changed, and what the reviewer still needs to verify.

Imported Workflow Notes

Imported: Overview

Radix UI provides unstyled, accessible components (primitives) that you can customize to match any design system. This skill guides you through building scalable component libraries with Radix UI, focusing on accessibility-first design, theming architecture, and composable patterns.

Key Strengths:

• Headless by design: Full styling control without fighting defaults
• Accessibility built-in: WAI-ARIA compliant, keyboard navigation, screen reader support
• Composable primitives: Build complex components from simple building blocks
• Framework agnostic: Works with React, but styles work anywhere

Imported: Getting Started

Installation

# Install individual primitives (recommended)
npm install @radix-ui/react-dialog @radix-ui/react-dropdown-menu

# Or install multiple at once
npm install @radix-ui/react-{dialog,dropdown-menu,tabs,tooltip}

# For styling (optional but common)
npm install clsx tailwind-merge class-variance-authority

Basic Component Pattern

Every Radix component follows this pattern:

import * as Dialog from '@radix-ui/react-dialog';

export function MyDialog() {
  return (
    <Dialog.Root>
      {/* Trigger the dialog */}
      <Dialog.Trigger asChild>
        <button className="trigger-styles">Open</button>
      </Dialog.Trigger>

      {/* Portal renders outside DOM hierarchy */}
      <Dialog.Portal>
        {/* Overlay (backdrop) */}
        <Dialog.Overlay className="overlay-styles" />
        
        {/* Content (modal) */}
        <Dialog.Content className="content-styles">
          <Dialog.Title>Title</Dialog.Title>
          <Dialog.Description>Description</Dialog.Description>
          
          {/* Your content here */}
          
          <Dialog.Close asChild>
            <button>Close</button>
          </Dialog.Close>
        </Dialog.Content>
      </Dialog.Portal>
    </Dialog.Root>
  );
}

Examples

Example 1: Ask for the upstream workflow directly

Use @radix-ui-design-system to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @radix-ui-design-system against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @radix-ui-design-system for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @radix-ui-design-system using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Imported Usage Notes

Imported: Real-World Examples

Example 1: Command Palette (Combo Dialog)

import * as Dialog from '@radix-ui/react-dialog';
import { Command } from 'cmdk';

export function CommandPalette() {
  const [open, setOpen] = useState(false);

  useEffect(() => {
    const down = (e: KeyboardEvent) => {
      if (e.key === 'k' && (e.metaKey || e.ctrlKey)) {
        e.preventDefault();
        setOpen((open) => !open);
      }
    };
    document.addEventListener('keydown', down);
    return () => document.removeEventListener('keydown', down);
  }, []);

  return (
    <Dialog.Root open={open} onOpenChange={setOpen}>
      <Dialog.Portal>
        <Dialog.Overlay className="fixed inset-0 bg-black/50" />
        <Dialog.Content className="fixed left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2">
          <Command>
            <Command.Input placeholder="Type a command..." />
            <Command.List>
              <Command.Empty>No results found.</Command.Empty>
              <Command.Group heading="Suggestions">
                <Command.Item>Calendar</Command.Item>
                <Command.Item>Search Emoji</Command.Item>
              </Command.Group>
            </Command.List>
          </Command>
        </Dialog.Content>
      </Dialog.Portal>
    </Dialog.Root>
  );
}

Example 2: Dropdown Menu with Icons

import * as DropdownMenu from '@radix-ui/react-dropdown-menu';
import { DotsHorizontalIcon } from '@radix-ui/react-icons';

export function ActionsMenu() {
  return (
    <DropdownMenu.Root>
      <DropdownMenu.Trigger asChild>
        <button className="icon-button" aria-label="Actions">
          <DotsHorizontalIcon />
        </button>
      </DropdownMenu.Trigger>

      <DropdownMenu.Portal>
        <DropdownMenu.Content className="dropdown-content" align="end">
          <DropdownMenu.Item className="dropdown-item">
            Edit
          </DropdownMenu.Item>
          <DropdownMenu.Item className="dropdown-item">
            Duplicate
          </DropdownMenu.Item>
          <DropdownMenu.Separator className="dropdown-separator" />
          <DropdownMenu.Item className="dropdown-item text-red-500">
            Delete
          </DropdownMenu.Item>
        </DropdownMenu.Content>
      </DropdownMenu.Portal>
    </DropdownMenu.Root>
  );
}

Example 3: Form with Radix Select + React Hook Form

import * as Select from '@radix-ui/react-select';
import { useForm, Controller } from 'react-hook-form';

interface FormData {
  country: string;
}

export function CountryForm() {
  const { control, handleSubmit } = useForm<FormData>();

  return (
    <form onSubmit={handleSubmit((data) => console.log(data))}>
      <Controller
        name="country"
        control={control}
        render={({ field }) => (
          <Select.Root onValueChange={field.onChange} value={field.value}>
            <Select.Trigger className="select-trigger">
              <Select.Value placeholder="Select a country" />
              <Select.Icon />
            </Select.Trigger>
            
            <Select.Portal>
              <Select.Content className="select-content">
                <Select.Viewport>
                  <Select.Item value="us">United States</Select.Item>
                  <Select.Item value="ca">Canada</Select.Item>
                  <Select.Item value="uk">United Kingdom</Select.Item>
                </Select.Viewport>
              </Select.Content>
            </Select.Portal>
          </Select.Root>
        )}
      />
      <button type="submit">Submit</button>
    </form>
  );
}

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keyboard Navigation: Full keyboard support (Tab, Arrow keys, Enter, Escape)
• Screen Readers: Proper ARIA attributes and live regions
• Focus Management: Automatic focus trapping and restoration
• Disabled States: Proper handling of disabled and aria-disabled
• Always use asChild to avoid wrapper divs
• Provide semantic HTML
• Use CSS variables for theming

Imported Operating Notes

Imported: Core Principles

1. Accessibility First

Every Radix primitive is built with accessibility as the foundation:

• Keyboard Navigation: Full keyboard support (Tab, Arrow keys, Enter, Escape)
• Screen Readers: Proper ARIA attributes and live regions
• Focus Management: Automatic focus trapping and restoration
• Disabled States: Proper handling of disabled and aria-disabled

Rule: Never override accessibility features. Enhance, don't replace.

2. Headless Architecture

Radix provides behavior, you provide appearance:

// ❌ Don't fight pre-styled components
<Button className="override-everything" />

// ✅ Radix gives you behavior, you add styling
<Dialog.Root>
  <Dialog.Trigger className="your-button-styles" />
  <Dialog.Content className="your-modal-styles" />
</Dialog.Root>

3. Composition Over Configuration

Build complex components from simple primitives:

// Primitive components compose naturally
<Tabs.Root>
  <Tabs.List>
    <Tabs.Trigger value="tab1">Tab 1</Tabs.Trigger>
    <Tabs.Trigger value="tab2">Tab 2</Tabs.Trigger>
  </Tabs.List>
  <Tabs.Content value="tab1">Content 1</Tabs.Content>
  <Tabs.Content value="tab2">Content 2</Tabs.Content>
</Tabs.Root>

Imported: Best Practices

✅ Do This

1. Always use

   asChild

   to avoid wrapper divs

   <Dialog.Trigger asChild>
     <button>Open</button>
   </Dialog.Trigger>
   

2. Provide semantic HTML

   <Dialog.Content asChild>
     <article role="dialog" aria-labelledby="title">
       {/* content */}
     </article>
   </Dialog.Content>
   

3. Use CSS variables for theming

   .dialog-content {
     background: hsl(var(--surface));
     color: hsl(var(--on-surface));
   }
   

4. Compose primitives for complex components

   function CommandPalette() {
     return (
       <Dialog.Root>
         <Dialog.Content>
           <Combobox /> {/* Radix Combobox inside Dialog */}
         </Dialog.Content>
       </Dialog.Root>
     );
   }
   

❌ Don't Do This

1. Don't skip accessibility parts

   // ❌ Missing Title and Description
   <Dialog.Content>
     <div>Content</div>
   </Dialog.Content>
   

2. Don't fight the primitives

   // ❌ Overriding internal behavior
   <Dialog.Content onClick={(e) => e.stopPropagation()}>
   

3. Don't mix controlled and uncontrolled

   // ❌ Inconsistent state management
   <Tabs.Root defaultValue="tab1" value={activeTab}>
   

4. Don't ignore keyboard navigation

   // ❌ Disabling keyboard behavior
   <DropdownMenu.Item onKeyDown={(e) => e.preventDefault()}>
   

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in

plugins/antigravity-awesome-skills-claude/skills/radix-ui-design-system

metadata.json

ORIGIN.md

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated

SKILL.md

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Troubleshooting Notes

Imported: Troubleshooting

Problem: Dialog doesn't close on Escape key

Cause:

onEscapeKeyDown

open

Solution:

<Dialog.Root open={open} onOpenChange={setOpen}>
  {/* Don't prevent default on escape */}
</Dialog.Root>

Problem: Dropdown menu positioning is off

Cause: Parent container has

overflow: hidden

Solution:

// Use Portal to render outside overflow container
<DropdownMenu.Portal>
  <DropdownMenu.Content />
</DropdownMenu.Portal>

Problem: Animations don't work

Cause: Portal content unmounts immediately

Solution:

// Use forceMount + AnimatePresence
<Dialog.Portal forceMount>
  <AnimatePresence>
    {open && <Dialog.Content />}
  </AnimatePresence>
</Dialog.Portal>

Problem: TypeScript errors with

asChild

Cause: Type inference issues with polymorphic components

Solution:

// Explicitly type your component
<Dialog.Trigger asChild>
  <button type="button">Open</button>
</Dialog.Trigger>

Imported: Theming Strategies

Strategy 1: CSS Variables (Framework-Agnostic)

Best for: Maximum portability, SSR-friendly

/* globals.css */
:root {
  --color-primary: 220 90% 56%;
  --color-surface: 0 0% 100%;
  --radius-base: 0.5rem;
  --shadow-lg: 0 10px 15px -3px rgb(0 0 0 / 0.1);
}

[data-theme="dark"] {
  --color-primary: 220 90% 66%;
  --color-surface: 222 47% 11%;
}

// Component.tsx
<Dialog.Content 
  className="
    bg-[hsl(var(--color-surface))]
    rounded-[var(--radius-base)]
    shadow-[var(--shadow-lg)]
  "
/>

Strategy 2: Tailwind + CVA (Class Variance Authority)

Best for: Tailwind projects, variant-heavy components

// button.tsx
import { cva, type VariantProps } from 'class-variance-authority';
import { cn } from '@/lib/utils';

const buttonVariants = cva(
  // Base styles
  "inline-flex items-center justify-center rounded-md font-medium transition-colors focus-visible:outline-none disabled:pointer-events-none disabled:opacity-50",
  {
    variants: {
      variant: {
        default: "bg-primary text-primary-foreground hover:bg-primary/90",
        destructive: "bg-destructive text-destructive-foreground hover:bg-destructive/90",
        outline: "border border-input bg-background hover:bg-accent",
        ghost: "hover:bg-accent hover:text-accent-foreground",
      },
      size: {
        default: "h-10 px-4 py-2",
        sm: "h-9 rounded-md px-3",
        lg: "h-11 rounded-md px-8",
        icon: "h-10 w-10",
      },
    },
    defaultVariants: {
      variant: "default",
      size: "default",
    },
  }
);

interface ButtonProps extends VariantProps<typeof buttonVariants> {
  children: React.ReactNode;
}

export function Button({ variant, size, children }: ButtonProps) {
  return (
    <button className={cn(buttonVariants({ variant, size }))}>
      {children}
    </button>
  );
}

Strategy 3: Stitches (CSS-in-JS)

Best for: Runtime theming, scoped styles

import { styled } from '@stitches/react';
import * as Dialog from '@radix-ui/react-dialog';

const StyledContent = styled(Dialog.Content, {
  backgroundColor: '$surface',
  borderRadius: '$md',
  padding: '$6',
  
  variants: {
    size: {
      small: { width: '300px' },
      medium: { width: '500px' },
      large: { width: '700px' },
    },
  },
  
  defaultVariants: {
    size: 'medium',
  },
});

Imported: Component Patterns

Pattern 1: Compound Components with Context

Use case: Share state between primitive parts

// Select.tsx
import * as Select from '@radix-ui/react-select';
import { CheckIcon, ChevronDownIcon } from '@radix-ui/react-icons';

export function CustomSelect({ items, placeholder, onValueChange }) {
  return (
    <Select.Root onValueChange={onValueChange}>
      <Select.Trigger className="select-trigger">
        <Select.Value placeholder={placeholder} />
        <Select.Icon>
          <ChevronDownIcon />
        </Select.Icon>
      </Select.Trigger>

      <Select.Portal>
        <Select.Content className="select-content">
          <Select.Viewport>
            {items.map((item) => (
              <Select.Item 
                key={item.value} 
                value={item.value}
                className="select-item"
              >
                <Select.ItemText>{item.label}</Select.ItemText>
                <Select.ItemIndicator>
                  <CheckIcon />
                </Select.ItemIndicator>
              </Select.Item>
            ))}
          </Select.Viewport>
        </Select.Content>
      </Select.Portal>
    </Select.Root>
  );
}

Pattern 2: Polymorphic Components with

asChild

Use case: Render as different elements without losing behavior

// ✅ Render as Next.js Link but keep Radix behavior
<Dialog.Trigger asChild>
  <Link href="/settings">Open Settings</Link>
</Dialog.Trigger>

// ✅ Render as custom component
<DropdownMenu.Item asChild>
  <YourCustomButton icon={<Icon />}>Action</YourCustomButton>
</DropdownMenu.Item>

Why

asChild

Pattern 3: Controlled vs Uncontrolled

// Uncontrolled (Radix manages state)
<Tabs.Root defaultValue="tab1">
  <Tabs.Trigger value="tab1">Tab 1</Tabs.Trigger>
</Tabs.Root>

// Controlled (You manage state)
const [activeTab, setActiveTab] = useState('tab1');

<Tabs.Root value={activeTab} onValueChange={setActiveTab}>
  <Tabs.Trigger value="tab1">Tab 1</Tabs.Trigger>
</Tabs.Root>

Rule: Use controlled when you need to sync with external state (URL, Redux, etc.).

Pattern 4: Animation with Framer Motion

import * as Dialog from '@radix-ui/react-dialog';
import { motion, AnimatePresence } from 'framer-motion';

export function AnimatedDialog({ open, onOpenChange }) {
  return (
    <Dialog.Root open={open} onOpenChange={onOpenChange}>
      <Dialog.Portal forceMount>
        <AnimatePresence>
          {open && (
            <>
              <Dialog.Overlay asChild>
                <motion.div
                  initial={{ opacity: 0 }}
                  animate={{ opacity: 1 }}
                  exit={{ opacity: 0 }}
                  className="dialog-overlay"
                />
              </Dialog.Overlay>
              
              <Dialog.Content asChild>
                <motion.div
                  initial={{ opacity: 0, scale: 0.95 }}
                  animate={{ opacity: 1, scale: 1 }}
                  exit={{ opacity: 0, scale: 0.95 }}
                  className="dialog-content"
                >
                  {/* Content */}
                </motion.div>
              </Dialog.Content>
            </>
          )}
        </AnimatePresence>
      </Dialog.Portal>
    </Dialog.Root>
  );
}

• Focus Management: Visible focus indicators on all interactive elements
• Keyboard Navigation: Full keyboard support (Tab, Arrows, Enter, Esc)
• ARIA Labels: Meaningful labels for screen readers
• Color Contrast: WCAG AA minimum (4.5:1 for text, 3:1 for UI)
• Error States: Clear error messages with

  aria-invalid

  and

  aria-describedby

• Loading States: Proper

  aria-busy

  during async operations

Dialog-Specific:

• Dialog.Title

  is present (required for screen readers)

• Dialog.Description

  provides context
• Focus trapped inside modal when open
• Escape key closes dialog
• Focus returns to trigger on close

Dropdown-Specific:

• Arrow keys navigate items
• Type-ahead search works
• First/last item wrapping behavior
• Selected state indicated visually and with ARIA

Imported: Performance Optimization

1. Code Splitting

// Lazy load heavy primitives
const Dialog = lazy(() => import('@radix-ui/react-dialog'));
const DropdownMenu = lazy(() => import('@radix-ui/react-dropdown-menu'));

2. Portal Container Reuse

// Create portal container once
<Tooltip.Provider>
  {/* All tooltips share portal container */}
  <Tooltip.Root>...</Tooltip.Root>
  <Tooltip.Root>...</Tooltip.Root>
</Tooltip.Provider>

3. Memoization

// Memoize expensive render functions
const SelectItems = memo(({ items }) => (
  items.map((item) => <Select.Item key={item.value} value={item.value} />)
));

Imported: Integration with Popular Tools

shadcn/ui (Built on Radix)

shadcn/ui is a collection of copy-paste components built with Radix + Tailwind.

npx shadcn-ui@latest init
npx shadcn-ui@latest add dialog

When to use shadcn vs raw Radix:

• Use shadcn: Quick prototyping, standard designs
• Use raw Radix: Full customization, unique designs

Radix Themes (Official Styled System)

import { Theme, Button, Dialog } from '@radix-ui/themes';

function App() {
  return (
    <Theme accentColor="crimson" grayColor="sand">
      <Button>Click me</Button>
    </Theme>
  );
}
