+ {message}
+
+```
+
+### Keyboard Patterns
+```tsx
+const handleKeyDown = (e: React.KeyboardEvent) => {
+ switch (e.key) {
+ case 'Enter':
+ case ' ':
+ e.preventDefault()
+ handleActivate()
+ break
+ case 'Escape':
+ e.preventDefault()
+ handleClose()
+ break
+ case 'ArrowDown':
+ e.preventDefault()
+ focusNext()
+ break
+ case 'ArrowUp':
+ e.preventDefault()
+ focusPrevious()
+ break
+ case 'Home':
+ e.preventDefault()
+ focusFirst()
+ break
+ case 'End':
+ e.preventDefault()
+ focusLast()
+ break
+ }
+}
+```
+
+## Validation Checklist
+
+### Forms
+- [ ] All inputs have associated labels
+- [ ] Required fields are marked with aria-required
+- [ ] Error messages are associated with aria-describedby
+- [ ] Form validation is announced to screen readers
+- [ ] Submit button is properly labeled
+
+### Modals/Dialogs
+- [ ] Focus is trapped within modal
+- [ ] Focus returns to trigger on close
+- [ ] Modal has proper ARIA attributes
+- [ ] Escape key closes modal
+- [ ] Background is inert (aria-hidden)
+
+### Navigation
+- [ ] Skip links are provided
+- [ ] Navigation has proper landmarks
+- [ ] Current page is indicated (aria-current)
+- [ ] Submenus are properly announced
+- [ ] Mobile menu is accessible
+
+### Data Tables
+- [ ] Table has caption or aria-label
+- [ ] Column headers are marked with th
+- [ ] Row headers use scope attribute
+- [ ] Sortable columns are announced
+- [ ] Empty states are described
+
+## Testing Tools
+
+```bash
+# Automated testing
+npm install -D @axe-core/react jest-axe
+
+# Manual testing checklist
+- [ ] Navigate with keyboard only
+- [ ] Test with screen reader (NVDA/JAWS/VoiceOver)
+- [ ] Check color contrast
+- [ ] Disable CSS and check structure
+- [ ] Test with 200% zoom
+- [ ] Verify focus indicators
+```
+
+## Common Issues and Fixes
+
+### Missing Labels
+```tsx
+// ❌ Bad
+
+
+// ✅ Good
+
+
+
+// ✅ Also good (visually hidden)
+
+
+```
+
+### Focus Indicators
+```tsx
+// Ensure visible focus
+className="focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2"
+```
+
+### Color Contrast
+```css
+/* Use CSS variables for consistent contrast */
+.text-muted-foreground {
+ color: hsl(var(--muted-foreground)); /* Ensure 4.5:1 ratio */
+}
+```

+
+### Framer Motion Integration
+```tsx
+import { motion, AnimatePresence, Variants } from "framer-motion"
+import * as React from "react"
+
+// Basic motion component setup
+const MotionDiv = motion.div
+const MotionButton = motion.button
+
+// Common animation variants
+export const fadeInUp: Variants = {
+ initial: {
+ opacity: 0,
+ y: 20,
+ },
+ animate: {
+ opacity: 1,
+ y: 0,
+ transition: {
+ duration: 0.4,
+ ease: "easeOut",
+ },
+ },
+ exit: {
+ opacity: 0,
+ y: -20,
+ transition: {
+ duration: 0.2,
+ ease: "easeIn",
+ },
+ },
+}
+
+export const scaleIn: Variants = {
+ initial: {
+ opacity: 0,
+ scale: 0.8,
+ },
+ animate: {
+ opacity: 1,
+ scale: 1,
+ transition: {
+ duration: 0.3,
+ ease: "easeOut",
+ },
+ },
+ exit: {
+ opacity: 0,
+ scale: 0.8,
+ transition: {
+ duration: 0.2,
+ ease: "easeIn",
+ },
+ },
+}
+
+export const slideInRight: Variants = {
+ initial: {
+ opacity: 0,
+ x: "100%",
+ },
+ animate: {
+ opacity: 1,
+ x: 0,
+ transition: {
+ duration: 0.3,
+ ease: "easeOut",
+ },
+ },
+ exit: {
+ opacity: 0,
+ x: "100%",
+ transition: {
+ duration: 0.2,
+ ease: "easeIn",
+ },
+ },
+}
+
+// Stagger animation for lists
+export const staggerContainer: Variants = {
+ animate: {
+ transition: {
+ staggerChildren: 0.1,
+ },
+ },
+}
+
+export const staggerChild: Variants = {
+ initial: {
+ opacity: 0,
+ y: 20,
+ },
+ animate: {
+ opacity: 1,
+ y: 0,
+ transition: {
+ duration: 0.4,
+ ease: "easeOut",
+ },
+ },
+}
+```
+
+### Animated Components
+
+#### Animated Button
+```tsx
+import { motion } from "framer-motion"
+import { Button, ButtonProps } from "@/components/ui/button"
+import { cn } from "@/lib/utils"
+
+interface AnimatedButtonProps extends ButtonProps {
+ animation?: "pulse" | "bounce" | "shake" | "glow"
+ loading?: boolean
+}
+
+export const AnimatedButton = React.forwardRef<
+ HTMLButtonElement,
+ AnimatedButtonProps
+>(({ className, animation = "pulse", loading, children, ...props }, ref) => {
+ const animations = {
+ pulse: {
+ scale: [1, 1.05, 1],
+ transition: { duration: 0.3 },
+ },
+ bounce: {
+ y: [0, -8, 0],
+ transition: { duration: 0.4, ease: "easeOut" },
+ },
+ shake: {
+ x: [0, -10, 10, -10, 10, 0],
+ transition: { duration: 0.4 },
+ },
+ glow: {
+ boxShadow: [
+ "0 0 0 0 rgba(var(--primary-rgb), 0)",
+ "0 0 0 10px rgba(var(--primary-rgb), 0.1)",
+ "0 0 0 0 rgba(var(--primary-rgb), 0)",
+ ],
+ transition: { duration: 1, repeat: Infinity },
+ },
+ }
+
+ return (
+
+
+ {todo.text}
+
+
+ )}
+ className="space-y-2"
+ />
+ )
+}
+```
+
+### Page Transitions
+```tsx
+import { motion, AnimatePresence } from "framer-motion"
+import { useRouter } from "next/router"
+
+const pageVariants: Variants = {
+ initial: {
+ opacity: 0,
+ x: "-100vw",
+ },
+ in: {
+ opacity: 1,
+ x: 0,
+ },
+ out: {
+ opacity: 0,
+ x: "100vw",
+ },
+}
+
+const pageTransition = {
+ type: "tween",
+ ease: "anticipate",
+ duration: 0.5,
+}
+
+export function PageTransition({ children }: { children: React.ReactNode }) {
+ const router = useRouter()
+
+ return (
+
+
+ )
+}
+
+// Shimmer effect
+const shimmerVariants: Variants = {
+ initial: {
+ backgroundPosition: "-200px 0",
+ },
+ animate: {
+ backgroundPosition: "calc(200px + 100%) 0",
+ transition: {
+ duration: 2,
+ ease: "linear",
+ repeat: Infinity,
+ },
+ },
+}
+
+export function ShimmerSkeleton({ className }: { className?: string }) {
+ return (
+
+
+ Static content
+ }
+
+ return (
+
+
+ {row.getValue("status")}
+
+
+ ),
+ },
+ {
+ accessorKey: "email",
+ header: "Email",
+ },
+ {
+ accessorKey: "amount",
+ header: () => Amount
,
+ cell: ({ row }) => {
+ const amount = parseFloat(row.getValue("amount"))
+ const formatted = new Intl.NumberFormat("en-US", {
+ style: "currency",
+ currency: "USD",
+ }).format(amount)
+
+ return {formatted}
+ },
+ },
+ {
+ accessorKey: "createdAt",
+ header: "Created",
+ cell: ({ row }) => {
+ const date = row.getValue("createdAt") as Date
+ return (
+
+ {date.toLocaleDateString()}
+
+ )
+ },
+ },
+ {
+ id: "actions",
+ enableHiding: false,
+ cell: ({ row }) => {
+ const payment = row.original
+
+ return (
+
+
+ )
+}
+```
+
+### Advanced Filtering
+```tsx
+import { Button } from "@/components/ui/button"
+import {
+ DropdownMenu,
+ DropdownMenuCheckboxItem,
+ DropdownMenuContent,
+ DropdownMenuTrigger,
+} from "@/components/ui/dropdown-menu"
+
+// Column visibility toggle
+
+
+ table.getColumn("email")?.setFilterValue(event.target.value)
+ }
+ className="max-w-sm"
+ />
+
+
+
+
+
+
+
+
+ {table.getFilteredSelectedRowModel().rows.length} of{" "}
+ {table.getFilteredRowModel().rows.length} row(s) selected.
+
+
+
+
+
+
+
+ )
+}
+
+// Usage in table cell
+{
+ accessorKey: "progress",
+ header: "Completion",
+ cell: ({ row }) => (
+
+ {label && {label}}
+ {showValue && (
+
+ {value} / {max}
+
+ )}
+
+
+
+
+ )
+}
+```
+
+### Export Functionality
+```tsx
+import { Button } from "@/components/ui/button"
+import { Download } from "lucide-react"
+
+export function ExportButton({ data, filename = 'data' }: {
+ data: any[]
+ filename?: string
+}) {
+ const exportToCSV = () => {
+ if (!data.length) return
+
+ const headers = Object.keys(data[0]).join(',')
+ const rows = data.map(row =>
+ Object.values(row).map(value =>
+ typeof value === 'string' ? `"${value}"` : value
+ ).join(',')
+ ).join('\n')
+
+ const csv = `${headers}\n${rows}`
+ const blob = new Blob([csv], { type: 'text/csv' })
+ const url = URL.createObjectURL(blob)
+
+ const link = document.createElement('a')
+ link.href = url
+ link.download = `${filename}.csv`
+ link.click()
+
+ URL.revokeObjectURL(url)
+ }
+
+ return (
+
+ )
+}
+```
+
+## Best Practices
+
+1. **Performance**
+ - Use virtualization for large datasets (1000+ rows)
+ - Implement proper memoization with React.memo
+ - Debounce search/filter inputs
+ - Use server-side pagination when possible
+
+2. **Accessibility**
+ - Include proper ARIA labels for sortable columns
+ - Ensure keyboard navigation works
+ - Provide screen reader announcements for data changes
+ - Use semantic table markup
+
+3. **User Experience**
+ - Show loading states during data fetching
+ - Provide empty state messages
+ - Include pagination controls
+ - Make columns resizable and sortable
+ - Implement persistent column preferences
+
+4. **Data Integrity**
+ - Validate data types before rendering
+ - Handle null/undefined values gracefully
+ - Provide fallback values for missing data
+ - Include error boundaries for chart components
+
+Remember: Data should tell a story - make it clear, accessible, and actionable!

+import { useForm } from "react-hook-form"
+import { zodResolver } from "@hookform/resolvers/zod"
+import * as z from "zod"
+import {
+ Form,
+ FormControl,
+ FormDescription,

+
+ {/* Row content */}
+
+ ))}
+
+ {data[virtualRow.index].name}
+
+
+
+ )}

+ const handleKeyDown = (event: KeyboardEvent) => {
+ if (event.key === 'Escape') {
+ setIsOpen(false)
+ }
+ }
+
+ if (isOpen) {
+ document.addEventListener('keydown', handleKeyDown)
+ return () => document.removeEventListener('keydown', handleKeyDown)
+ }
+ }, [isOpen])
+
+ return (
+
+ )
+}
+```
+
+### Form Migration
+```tsx
+// BEFORE: Legacy form with custom validation
+import { useState } from 'react'
+
+interface FormData {
+ email: string
+ password: string
+}
+
+interface FormErrors {
+ email?: string
+ password?: string
+}
+
+export function LegacyForm() {
+ const [data, setData] = useState
+
+ {title}
+ {children} + +
+
+ ),
+}
+```
+
+### Automated Testing
+```tsx
+// Jest test for migration compatibility
+import { render, screen } from '@testing-library/react'
+import userEvent from '@testing-library/user-event'
+import { Button } from './Button'
+import { LegacyButton } from './LegacyButton'
+
+describe('Button Migration', () => {
+ it('should maintain same API for basic usage', () => {
+ const handleClick = jest.fn()
+
+ render()
+ render(
+
+ Legacy Button
+
+ Primary
+ Secondary
+ Danger
+
+
+
+ New Button
+
+
+
+
+
+
+ Loading visualization...
}>
+ Dashboard
+Loading admin panel...
,
+})
+
+export function App({ user }: { user: User }) {
+ return (
+
+ {user.isAdmin && (
+ Loading...
}>
+
+ {processedData.map(item => (
+
+ )
+ },
+ // Custom comparison function
+ (prevProps, nextProps) => {
+ return (
+ prevProps.data.length === nextProps.data.length &&
+ prevProps.data.every((item, index) =>
+ item.id === nextProps.data[index].id &&
+ item.version === nextProps.data[index].version
+ )
+ )
+ }
+)
+
+// Optimize context providers
+const ThemeContext = React.createContext
+ {renderItem({ index, style })}
+
+ ))
+
+ return (
+ -
+ {Row}
+
+
+
+
+ )
+}
+```
+
+### Debounced Inputs and Search
+```tsx
+import { useMemo, useState, useCallback } from 'react'
+import { debounce } from 'lodash-es'
+import { Input } from '@/components/ui/input'
+
+export function OptimizedSearch({
+ onSearch,
+ placeholder = "Search...",
+ debounceMs = 300,
+}: {
+ onSearch: (query: string) => void
+ placeholder?: string
+ debounceMs?: number
+}) {
+ const [query, setQuery] = useState('')
+
+ // Debounce search function
+ const debouncedSearch = useMemo(
+ () => debounce(onSearch, debounceMs),
+ [onSearch, debounceMs]
+ )
+
+ const handleInputChange = useCallback((e: React.ChangeEvent
+ 
setLoaded(true)}
+ onError={() => setError(true)}
+ />
+ {!loaded && !error && (
+
+ )}
+ {error && (
+
+ )
+}
+```
+
+### Resource Preloading
+```tsx
+// Preload critical resources
+export function useResourcePreload() {
+ useEffect(() => {
+ // Preload critical fonts
+ const fontLink = document.createElement('link')
+ fontLink.rel = 'preload'
+ fontLink.href = '/fonts/inter-var.woff2'
+ fontLink.as = 'font'
+ fontLink.type = 'font/woff2'
+ fontLink.crossOrigin = 'anonymous'
+ document.head.appendChild(fontLink)
+
+ // Preload critical images
+ const criticalImages = [
+ '/images/logo.svg',
+ '/images/hero-bg.jpg',
+ ]
+
+ criticalImages.forEach(src => {
+ const link = document.createElement('link')
+ link.rel = 'preload'
+ link.href = src
+ link.as = 'image'
+ document.head.appendChild(link)
+ })
+
+ // Prefetch next page resources
+ const prefetchLink = document.createElement('link')
+ prefetchLink.rel = 'prefetch'
+ prefetchLink.href = '/dashboard'
+ document.head.appendChild(prefetchLink)
+ }, [])
+}
+
+// Smart component preloading
+export function useComponentPreload(condition: boolean, importFn: () => Promise
+ Failed to load
+
+ )}
+
+
+
+ )
+}
+```
+
+## Performance Monitoring
+
+### Performance Metrics Tracking
+```tsx
+import { useEffect } from 'react'
+
+export function usePerformanceMetrics() {
+ useEffect(() => {
+ // Measure component render time
+ const startTime = performance.now()
+
+ return () => {
+ const endTime = performance.now()
+ const renderTime = endTime - startTime
+
+ if (renderTime > 16) { // 60fps threshold
+ console.warn(`Slow render detected: ${renderTime}ms`)
+ }
+
+ // Send metrics to monitoring service
+ if (typeof window !== 'undefined' && window.gtag) {
+ window.gtag('event', 'timing_complete', {
+ name: 'component_render',
+ value: renderTime,
+ })
+ }
+ }
+ })
+}
+
+// Bundle size monitoring
+export function trackBundleSize() {
+ if (typeof window !== 'undefined' && 'performance' in window) {
+ window.addEventListener('load', () => {
+ const navigation = performance.getEntriesByType('navigation')[0] as PerformanceNavigationTiming
+ const resources = performance.getEntriesByType('resource') as PerformanceResourceTiming[]
+
+ const jsSize = resources
+ .filter(resource => resource.name.includes('.js'))
+ .reduce((total, resource) => total + (resource.transferSize || 0), 0)
+
+ const cssSize = resources
+ .filter(resource => resource.name.includes('.css'))
+ .reduce((total, resource) => total + (resource.transferSize || 0), 0)
+
+ console.log('Bundle sizes:', {
+ js: `${(jsSize / 1024).toFixed(2)}KB`,
+ css: `${(cssSize / 1024).toFixed(2)}KB`,
+ total: `${((jsSize + cssSize) / 1024).toFixed(2)}KB`,
+ })
+ })
+ }
+}
+```
+
+### Memory Leak Prevention
+```tsx
+// Cleanup patterns
+export function useEventListener(
+ eventName: string,
+ handler: (event: Event) => void,
+ element: HTMLElement | Window = window
+) {
+ const savedHandler = useRef(handler)
+
+ useEffect(() => {
+ savedHandler.current = handler
+ }, [handler])
+
+ useEffect(() => {
+ const eventListener = (event: Event) => savedHandler.current(event)
+ element.addEventListener(eventName, eventListener)
+
+ return () => {
+ element.removeEventListener(eventName, eventListener)
+ }
+ }, [eventName, element])
+}
+
+// Intersection Observer cleanup
+export function useIntersectionObserver(
+ elementRef: React.RefObject
+```
+
+## Dark Mode Implementation
+
+### CSS Variables
+```css
+@layer base {
+ :root {
+ --background: 0 0% 100%;
+ --foreground: 222.2 84% 4.9%;
+ }
+
+ .dark {
+ --background: 222.2 84% 4.9%;
+ --foreground: 210 40% 98%;
+ }
+}
+
+@layer base {
+ * {
+ @apply border-border;
+ }
+ body {
+ @apply bg-background text-foreground;
+ }
+}
+```
+
+### Component Classes
+```tsx
+// Automatic dark mode support via CSS variables
+className="bg-background text-foreground"
+
+// Explicit dark mode classes (when needed)
+className="bg-white dark:bg-gray-900"
+```
+
+## Performance Optimization
+
+### Purge Configuration
+```js
+// Ensure all dynamic classes are included
+content: [
+ './src/**/*.{js,ts,jsx,tsx,mdx}',
+ // Include safelist for dynamic classes
+],
+safelist: [
+ 'bg-red-500',
+ 'text-3xl',
+ 'lg:text-4xl',
+ // Dynamic classes that might be generated
+]
+```
+
+### Critical CSS
+```tsx
+// Inline critical styles
+
+```
+
+## Common Patterns
+
+### Gradient Utilities
+```tsx
+className="bg-gradient-to-r from-primary to-secondary"
+```
+
+### Animation Utilities
+```tsx
+className="transition-all duration-200 ease-in-out"
+className="animate-pulse"
+className="motion-safe:animate-spin motion-reduce:animate-none"
+```
+
+### Typography
+```tsx
+className="text-sm font-medium leading-none"
+className="text-muted-foreground"
+className="truncate" // text-overflow: ellipsis
+```
+
+### Spacing System
+```tsx
+// Consistent spacing scale
+className="space-y-4" // Vertical spacing between children
+className="gap-4" // Gap in flex/grid
+className="p-6" // Padding
+className="m-auto" // Margin
+```
+
+## Best Practices
+
+1. **Use semantic color names** (primary, secondary, muted)
+2. **Leverage CSS variables** for theming
+3. **Sort classes consistently** for readability
+4. **Avoid arbitrary values** when possible
+5. **Use component variants** over conditional classes
+6. **Optimize for production** with PurgeCSS
+7. **Test responsive designs** at all breakpoints
+8. **Maintain consistent spacing** scale
+
+## Debugging Tips
+
+```bash
+# Check Tailwind config
+npx tailwindcss init --full
+
+# Build CSS and check output
+npx tailwindcss -i ./src/input.css -o ./dist/output.css --watch
+
+# Analyze bundle size
+npx tailwindcss -i ./src/input.css -o ./dist/output.css --minify
+```
+

+
+### Theme Provider Setup
+```tsx
+import * as React from "react"
+import { ThemeProvider as NextThemesProvider } from "next-themes"
+import { type ThemeProviderProps } from "next-themes/dist/types"
+
+export function ThemeProvider({ children, ...props }: ThemeProviderProps) {
+ return {children}
+}
+
+// Usage in app
+import { ThemeProvider } from "@/components/theme-provider"
+
+export default function RootLayout({
+ children,
+}: {
+ children: React.ReactNode
+}) {
+ return (
+
+
+
+ {children}
+
+
+
+ )
+}
+```
+
+### Theme Toggle Component
+```tsx
+import * as React from "react"
+import { Moon, Sun } from "lucide-react"
+import { useTheme } from "next-themes"
+import { Button } from "@/components/ui/button"
+import {
+ DropdownMenu,
+ DropdownMenuContent,
+ DropdownMenuItem,
+ DropdownMenuTrigger,
+} from "@/components/ui/dropdown-menu"
+
+export function ModeToggle() {
+ const { setTheme } = useTheme()
+
+ return (
+
+
+
+
+
+ setTheme("light")}>
+ Light
+
+ setTheme("dark")}>
+ Dark
+
+ setTheme("system")}>
+ System
+
+
+
+ )
+}
+```
+
+## Custom Theme Creation
+
+### Brand Color Integration
+```tsx
+// Create custom theme configuration
+export const createTheme = (brandColors: {
+ primary: string
+ secondary: string
+ accent?: string
+}) => {
+ return {
+ extend: {
+ colors: {
+ brand: {
+ primary: brandColors.primary,
+ secondary: brandColors.secondary,
+ accent: brandColors.accent || brandColors.primary,
+ },
+ // Override default colors
+ primary: {
+ DEFAULT: brandColors.primary,
+ foreground: "hsl(var(--primary-foreground))",
+ },
+ },
+ },
+ }
+}
+
+// Usage in tailwind.config.js
+module.exports = {
+ content: [...],
+ theme: {
+ ...createTheme({
+ primary: "hsl(240, 100%, 50%)", // Brand blue
+ secondary: "hsl(280, 100%, 70%)", // Brand purple
+ }),
+ },
+}
+```
+
+### Dynamic Theme Generator
+```tsx
+import { useState, useEffect } from "react"
+
+export function useCustomTheme() {
+ const [customColors, setCustomColors] = useState({
+ primary: "222.2 47.4% 11.2%",
+ secondary: "210 40% 96%",
+ accent: "210 40% 96%",
+ })
+
+ const applyCustomTheme = (colors: typeof customColors) => {
+ const root = document.documentElement
+
+ Object.entries(colors).forEach(([key, value]) => {
+ root.style.setProperty(`--${key}`, value)
+ })
+
+ setCustomColors(colors)
+ }
+
+ const generateColorPalette = (baseColor: string) => {
+ // Color manipulation logic
+ const hsl = parseHSL(baseColor)
+
+ return {
+ primary: baseColor,
+ secondary: `${hsl.h} ${Math.max(hsl.s - 20, 0)}% ${Math.min(hsl.l + 30, 100)}%`,
+ accent: `${(hsl.h + 30) % 360} ${hsl.s}% ${hsl.l}%`,
+ muted: `${hsl.h} ${Math.max(hsl.s - 40, 0)}% ${Math.min(hsl.l + 40, 95)}%`,
+ }
+ }
+
+ return {
+ customColors,
+ applyCustomTheme,
+ generateColorPalette,
+ }
+}
+```
+
+## Component Theming Patterns
+
+### Themed Component Variants
+```tsx
+import { cva } from "class-variance-authority"
+
+const buttonVariants = cva(
+ "inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors",
+ {
+ 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 hover:bg-accent hover:text-accent-foreground",
+ secondary: "bg-secondary text-secondary-foreground hover:bg-secondary/80",
+ ghost: "hover:bg-accent hover:text-accent-foreground",
+ link: "underline-offset-4 hover:underline text-primary",
+ // Custom brand variants
+ brand: "bg-brand-primary text-white hover:bg-brand-primary/90",
+ gradient: "bg-gradient-to-r from-primary to-accent text-primary-foreground hover:opacity-90",
+ },
+ size: {
+ default: "h-10 py-2 px-4",
+ sm: "h-9 px-3 rounded-md",
+ lg: "h-11 px-8 rounded-md",
+ icon: "h-10 w-10",
+ },
+ },
+ defaultVariants: {
+ variant: "default",
+ size: "default",
+ },
+ }
+)
+```
+
+### Contextual Color System
+```tsx
+// Create semantic color contexts
+export const semanticColors = {
+ success: {
+ light: "hsl(142, 76%, 36%)",
+ dark: "hsl(142, 71%, 45%)",
+ },
+ warning: {
+ light: "hsl(38, 92%, 50%)",
+ dark: "hsl(38, 92%, 50%)",
+ },
+ error: {
+ light: "hsl(0, 84%, 60%)",
+ dark: "hsl(0, 63%, 31%)",
+ },
+ info: {
+ light: "hsl(199, 89%, 48%)",
+ dark: "hsl(199, 89%, 48%)",
+ },
+}
+
+// Status indicator component
+export function StatusIndicator({
+ status,
+ children
+}: {
+ status: keyof typeof semanticColors
+ children: React.ReactNode
+}) {
+ return (
+
+
+# Use React Testing Library
+npm test -- --coverage
+```

+Create a fully-featured data table using TanStack Table and shadcn/ui components.
+
+## Instructions
+
+1. Install required dependencies:
+ - `@tanstack/react-table`
+ - Required shadcn components: `table`, `button`, `input`, `dropdown-menu`
+
+2. Create data table with features:
+ - Column definitions with proper types
+ - Sorting functionality
+ - Filtering (global and column)
+ - Pagination
+ - Row selection
+ - Column visibility toggle
+ - Export functionality (optional)
+
+## Template Structure
+
+```tsx
+// components/[table-name]/columns.tsx
+import { ColumnDef } from "@tanstack/react-table"
+import { Button } from "@/components/ui/button"

+
+Add a new variant to an existing shadcn/ui component using CVA (class-variance-authority).
+
+## Instructions
+
+1. Locate the component file in `components/ui/[component].tsx`
+2. Find the existing CVA variants configuration
+3. Add the new variant to the appropriate variant type
+4. Update TypeScript types if needed
+5. Provide usage example of the new variant
+
+## Arguments
+
+- `component-name`: The component to modify (e.g., `button`, `card`)
+- `variant-type`: The type of variant (`variant`, `size`, or custom)
+- `variant-name`: The name of the new variant
+
+## Example
+
+If the user says: `/create-variant button size=xl`
+
+1. Open `components/ui/button.tsx`
+2. Find the `buttonVariants` CVA configuration
+3. Add to the `size` variants:
+
+```tsx
+const buttonVariants = cva(
+ "...",
+ {
+ variants: {
+ variant: { ... },
+ size: {
+ default: "h-9 px-4 py-2",
+ sm: "h-8 rounded-md px-3 text-xs",
+ lg: "h-10 rounded-md px-8",
+ icon: "h-9 w-9",
+ // NEW VARIANT
+ xl: "h-12 rounded-md px-10 text-lg",
+ },
+ },
+ }
+)
+```
+
+4. Show usage:
+```tsx
+
+```
+
+## Common Variant Types
+
+- **variant**: Visual style (default, destructive, outline, secondary, ghost, link)
+- **size**: Component size (sm, default, lg, xl)
+- **state**: Interactive state (active, disabled, loading)
+- **theme**: Theme-specific (brand, success, warning, info)
+
+## Best Practices
+
+1. Keep variant names consistent across components
+2. Update TypeScript types when adding variants
+3. Test the variant with all other variant combinations
+4. Ensure accessibility is maintained
+5. Document the new variant in comments

+description: Migrate existing component to shadcn/ui patterns
+argument-hint:
+allowed-tools: Read, Write, Edit, MultiEdit, Bash
+---
+
+Convert an existing component to follow shadcn/ui patterns and best practices.
+
+## Instructions
+
+1. Analyze the existing component
+2. Identify required shadcn/ui dependencies
+3. Refactor to use:
+ - CVA for variants
+ - cn() for class merging
+ - Radix UI primitives (if applicable)
+ - Proper TypeScript types
+ - forwardRef pattern
+ - Accessibility attributes
+4. Maintain backward compatibility where possible
+5. Create migration guide
+
+## Migration Patterns
+
+### From Styled Components/Emotion
+```tsx
+// ❌ Before - Styled Components
+const StyledButton = styled.button`
+ background: ${props => props.primary ? 'blue' : 'gray'};
+ color: white;
+ padding: 10px 20px;
+ &:hover {
+ opacity: 0.8;
+ }
+`
+
+// ✅ After - shadcn/ui pattern
+import { cva, type VariantProps } from "class-variance-authority"
+import { cn } from "@/lib/utils"
+
+const buttonVariants = cva(
+ "inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors focus-visible:outline-none focus-visible:ring-2",
+ {
+ variants: {
+ variant: {
+ primary: "bg-blue-600 text-white hover:bg-blue-700",
+ secondary: "bg-gray-600 text-white hover:bg-gray-700",
+ },
+ },
+ defaultVariants: {
+ variant: "primary",
+ },
+ }
+)
+
+const Button = React.forwardRef<
+ HTMLButtonElement,
+ React.ButtonHTMLAttributes &
+ VariantProps
+>(({ className, variant, ...props }, ref) => {
+ return (
+
+ )
+})
+Button.displayName = "Button"
+```
+
+### From Material-UI/Ant Design
+```tsx
+// ❌ Before - MUI
+import { Button, TextField, Dialog } from '@mui/material'
+
+
+
+// ✅ After - shadcn/ui
+import {
+ Dialog,
+ DialogContent,
+ DialogDescription,
+ DialogFooter,
+ DialogHeader,
+ DialogTitle,
+} from "@/components/ui/dialog"
+import { Input } from "@/components/ui/input"
+import { Label } from "@/components/ui/label"
+import { Button } from "@/components/ui/button"
+
+
+```
+
+### From Bootstrap/Traditional CSS
+```tsx
+// ❌ Before - Bootstrap classes
+
+
+ Title
+
+
+
+
+
+
+
+```

+description: Set up a form with React Hook Form and Zod validation
+argument-hint:
+allowed-tools: Read, Write, Edit, Bash
+---
+
+Create a complete form setup with React Hook Form, Zod validation, and shadcn/ui form components.
+
+## Instructions
+
+1. Install required dependencies if not present:
+ - `react-hook-form`
+ - `@hookform/resolvers`
+ - `zod`
+ - Required shadcn components: `form`, `input`, `button`, etc.
+
+2. Create the form with:
+ - Zod schema for validation
+ - Form component with React Hook Form
+ - Proper error handling
+ - Loading states
+ - Success feedback
+
+## Template Structure
+
+```tsx
+// lib/validations/[form-name].ts
+import * as z from "zod"
+
+export const [formName]Schema = z.object({
+ // Define fields
+})
+
+export type [FormName]Values = z.infer
+
+// components/forms/[form-name]-form.tsx
+import { useForm } from "react-hook-form"
+import { zodResolver } from "@hookform/resolvers/zod"
+import { [formName]Schema, type [FormName]Values } from "@/lib/validations/[form-name]"
+import {
+ Form,
+ FormControl,
+ FormDescription,
+ FormField,
+ FormItem,
+ FormLabel,
+ FormMessage,
+} from "@/components/ui/form"
+import { Input } from "@/components/ui/input"
+import { Button } from "@/components/ui/button"
+import { toast } from "@/components/ui/use-toast"
+
+export function [FormName]Form() {
+ const form = useForm<[FormName]Values>({
+ resolver: zodResolver([formName]Schema),
+ defaultValues: {
+ // Set defaults
+ },
+ })
+
+ async function onSubmit(data: [FormName]Values) {
+ try {
+ // Handle submission
+ toast({
+ title: "Success",
+ description: "Form submitted successfully",
+ })
+ } catch (error) {
+ toast({
+ title: "Error",
+ description: "Something went wrong",
+ variant: "destructive",
+ })
+ }
+ }
+
+ return (
+
+
+ )
+}
+```
+
+## Common Form Types
+
+- **contact-form**: Name, email, message
+- **login-form**: Email/username, password
+- **register-form**: Name, email, password, confirm password
+- **profile-form**: Avatar, bio, social links
+- **settings-form**: Preferences, notifications
+- **checkout-form**: Billing, shipping, payment
+
+## Field Types to Consider
+
+- Text inputs (email, url, tel, password)
+- Textareas for long text
+- Select dropdowns
+- Radio groups
+- Checkboxes
+- Date pickers
+- File uploads
+- Number inputs with validation
+
+## Example
+
+If the user says: `/setup-form contact`
+
+1. Install dependencies:
+```bash
+npm install react-hook-form @hookform/resolvers zod
+npx shadcn@latest add form input textarea button
+```
+
+2. Create validation schema
+3. Create form component with name, email, message fields
+4. Add proper validation rules
+5. Include submit handler with loading state

+## Advanced Theming Features
+
+### CSS-in-JS Theme Integration
+```tsx
+import { createStitches } from "@stitches/react"
+
+export const { styled, css, globalCss, keyframes, getCssText, theme, createTheme, config } = createStitches({
+ theme: {
+ colors: {
+ primary: "hsl(var(--primary))",
+ secondary: "hsl(var(--secondary))",
+ background: "hsl(var(--background))",
+ foreground: "hsl(var(--foreground))",
+ },
+ space: {
+ 1: "0.25rem",
+ 2: "0.5rem",
+ 3: "0.75rem",
+ 4: "1rem",
+ 5: "1.25rem",
+ 6: "1.5rem",
+ },
+ radii: {
+ sm: "0.375rem",
+ md: "0.5rem",
+ lg: "0.75rem",
+ },
+ },
+})
+
+// Dark theme variant
+export const darkTheme = createTheme("dark-theme", {
+ colors: {
+ primary: "hsl(var(--primary))",
+ secondary: "hsl(var(--secondary))",
+ background: "hsl(var(--background))",
+ foreground: "hsl(var(--foreground))",
+ },
+})
+
+// Usage
+const Button = styled("button", {
+ backgroundColor: "$primary",
+ color: "$background",
+ padding: "$3 $5",
+ borderRadius: "$md",
+})
+```
+
+### Animation Theme Integration
+```css
+/* Custom animation utilities */
+.animate-theme-transition {
+ transition-property: background-color, border-color, color, fill, stroke;
+ transition-timing-function: cubic-bezier(0.4, 0, 0.2, 1);
+ transition-duration: var(--duration-normal);
+}
+
+.animate-slide-in {
+ animation: slide-in var(--duration-normal) var(--ease-in-out);
+}
+
+@keyframes slide-in {
+ from {
+ transform: translateY(-100%);
+ opacity: 0;
+ }
+ to {
+ transform: translateY(0);
+ opacity: 1;
+ }
+}
+
+/* Theme-aware gradients */
+.bg-theme-gradient {
+ background: linear-gradient(
+ 135deg,
+ hsl(var(--primary)) 0%,
+ hsl(var(--accent)) 50%,
+ hsl(var(--secondary)) 100%
+ );
+}
+```
+
+### Responsive Theme Tokens
+```css
+/* Responsive spacing system */
+:root {
+ --container-padding: 1rem;
+ --grid-gap: 1rem;
+ --section-spacing: 2rem;
+}
+
+@media (min-width: 768px) {
+ :root {
+ --container-padding: 2rem;
+ --grid-gap: 1.5rem;
+ --section-spacing: 3rem;
+ }
+}
+
+@media (min-width: 1024px) {
+ :root {
+ --container-padding: 3rem;
+ --grid-gap: 2rem;
+ --section-spacing: 4rem;
+ }
+}
+
+/* Responsive typography */
+.text-responsive-xl {
+ font-size: clamp(1.5rem, 4vw, 3rem);
+ line-height: 1.2;
+}
+```
+
+## Theme Validation and Testing
+
+### Color Contrast Checker
+```tsx
+export function checkColorContrast(foreground: string, background: string): {
+ ratio: number
+ aaLarge: boolean
+ aa: boolean
+ aaa: boolean
+} {
+ const getLuminance = (color: string): number => {
+ // Convert color to RGB and calculate luminance
+ // Implementation details...
+ return 0.5 // Placeholder
+ }
+
+ const fg = getLuminance(foreground)
+ const bg = getLuminance(background)
+ const ratio = (Math.max(fg, bg) + 0.05) / (Math.min(fg, bg) + 0.05)
+
+ return {
+ ratio,
+ aaLarge: ratio >= 3,
+ aa: ratio >= 4.5,
+ aaa: ratio >= 7,
+ }
+}
+```
+
+### Theme Preview Component
+```tsx
+export function ThemePreview({ theme }: { theme: any }) {
+ return (
+
+
+ )
+}
+```
+
+## Best Practices
+
+1. **Design Token Organization**
+ - Use semantic naming (primary, secondary, not blue, red)
+ - Maintain consistent naming conventions
+ - Group related tokens together
+ - Version your design tokens
+
+2. **Color Accessibility**
+ - Test contrast ratios for all color combinations
+ - Ensure colors work for colorblind users
+ - Don't rely solely on color to convey information
+ - Provide sufficient contrast in both themes
+
+3. **Performance Optimization**
+ - Use CSS custom properties for runtime changes
+ - Avoid inline styles for theme values
+ - Minimize CSS-in-JS overhead
+ - Cache theme calculations
+
+4. **Developer Experience**
+ - Provide TypeScript types for theme tokens
+ - Include theme documentation
+ - Create theme development tools
+ - Maintain consistent API patterns
+
+Remember: Great themes are invisible to users but make everything feel cohesive and professional!

+description: Add shadcn/ui components to your project
+argument-hint: "[component-names...]"
+allowed-tools: Bash, Read, Write
+---
+
+Add one or more shadcn/ui components to your project.
+
+## Instructions
+
+1. Check if shadcn/ui is initialized in the project
+2. If not initialized, suggest running `npx shadcn@latest init` first
+3. For each component requested:
+ - Run `npx shadcn@latest add [component]`
+ - Verify component was added successfully
+ - Check for any peer dependencies
+4. If components have dependencies on each other, install in correct order
+5. Provide usage examples for the installed components
+
+## Component Dependencies
+
+Some components depend on others:
+- `form` requires `button`, `label`, `input`
+- `data-table` requires `table`, `button`, `dropdown-menu`, `input`
+- `date-picker` requires `button`, `calendar`, `popover`
+- `combobox` requires `command`, `popover`, `button`
+
+## Common Components
+
+**Layout**: card, separator, aspect-ratio, scroll-area
+**Forms**: input, label, button, select, checkbox, radio-group, switch, textarea, form
+**Overlays**: dialog, alert-dialog, sheet, popover, tooltip, hover-card
+**Navigation**: navigation-menu, tabs, breadcrumb, pagination
+**Data**: table, data-table, badge, avatar, progress
+**Feedback**: alert, toast, skeleton, sonner
+
+## Arguments
+
+- Component names separated by spaces: `button card dialog`
+- Or use `--all` to add all available components
+
+## Example
+
+If the user says: `/add-component form select date-picker`
+
+Execute:
+```bash
+npx shadcn@latest add form
+npx shadcn@latest add select
+npx shadcn@latest add date-picker
+```
+
+Then provide usage examples for each component added.

+
+Analyze components for accessibility issues and provide recommendations.
+
+## Instructions
+
+1. If no path specified, analyze all components in `components/ui/`
+2. Check for common accessibility issues
+3. Verify WCAG 2.1 AA compliance
+4. Provide specific recommendations for fixes
+5. Generate accessibility report
+
+## Checks to Perform
+
+### HTML Semantics
+- [ ] Proper heading hierarchy (h1 → h2 → h3)
+- [ ] Semantic HTML elements used appropriately
+- [ ] Lists use ul/ol with li elements
+- [ ] Buttons vs links used correctly
+
+### ARIA Implementation
+- [ ] Required ARIA attributes present
+- [ ] ARIA roles used appropriately
+- [ ] aria-label or aria-labelledby for interactive elements
+- [ ] aria-describedby for additional context
+- [ ] Live regions for dynamic content
+
+### Keyboard Navigation
+- [ ] All interactive elements keyboard accessible
+- [ ] Tab order is logical
+- [ ] Focus indicators visible
+- [ ] Escape key closes modals/popups
+- [ ] Arrow keys work in menus/lists
+
+### Forms
+- [ ] All inputs have associated labels
+- [ ] Required fields marked with aria-required
+- [ ] Error messages associated with inputs
+- [ ] Form validation accessible
+
+### Images & Media
+- [ ] Images have alt text
+- [ ] Decorative images have empty alt=""
+- [ ] Videos have captions/transcripts
+- [ ] Audio has transcripts
+
+### Color & Contrast
+- [ ] Text contrast ratio ≥ 4.5:1 (normal text)
+- [ ] Text contrast ratio ≥ 3:1 (large text)
+- [ ] Focus indicators have sufficient contrast
+- [ ] Information not conveyed by color alone
+
+### Motion & Animation
+- [ ] Respects prefers-reduced-motion
+- [ ] Animations can be paused/stopped
+- [ ] No flashing content (seizure risk)
+
+## Automated Testing
+
+Install and run automated tools:
+```bash
+# Install testing dependencies
+npm install -D @axe-core/react jest-axe
+
+# Run axe-core tests
+npx axe
+
+
+ Colors
+ {Object.entries(theme.colors).map(([name, value]) => ( +
+
+ {name}
+
+ ))}
+ {value}
+
+
+ Components
+ + + +
+ {message}
+
+```
+
+## Example
+
+If the user says: `/analyze-accessibility`
+
+1. Scan all components in components/ui/
+2. Check each component against accessibility checklist
+3. Run automated tests if available
+4. Generate detailed report with:
+ - Issues found
+ - Specific fixes needed
+ - Code examples
+ - Priority levels
