+description: Migrate existing component to shadcn/ui patterns
+argument-hint: <component-file>
+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<HTMLButtonElement> &
+    VariantProps<typeof buttonVariants>
+>(({ className, variant, ...props }, ref) => {
+  return (
+    <button
+      ref={ref}
+      className={cn(buttonVariants({ variant, className }))}
+      {...props}
+    />
+  )
+})
+Button.displayName = "Button"
+```
+
+### From Material-UI/Ant Design
+```tsx
+// ❌ Before - MUI
+import { Button, TextField, Dialog } from '@mui/material'
+
+<Dialog open={open} onClose={handleClose}>
+  <DialogTitle>Title</DialogTitle>
+  <DialogContent>
+    <TextField label="Name" />
+  </DialogContent>
+  <DialogActions>
+    <Button onClick={handleClose}>Cancel</Button>
+  </DialogActions>
+</Dialog>
+
+// ✅ 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"
+
+<Dialog open={open} onOpenChange={setOpen}>
+  <DialogContent>
+    <DialogHeader>
+      <DialogTitle>Title</DialogTitle>
+    </DialogHeader>
+    <div className="grid gap-4 py-4">
+      <div className="grid gap-2">
+        <Label htmlFor="name">Name</Label>
+        <Input id="name" />
+      </div>
+    </div>
+    <DialogFooter>
+      <Button variant="outline" onClick={() => setOpen(false)}>
+        Cancel
+      </Button>
+    </DialogFooter>
+  </DialogContent>
+</Dialog>
+```
+
+### From Bootstrap/Traditional CSS
+```tsx
+// ❌ Before - Bootstrap classes
+<div className="card">
+  <div className="card-header">
+    <h5 className="card-title">Title</h5>
+  </div>
+  <div className="card-body">
+    <p className="card-text">Content</p>
+    <button className="btn btn-primary">Action</button>
+  </div>
+</div>
+
+// ✅ After - shadcn/ui
+import {
+  Card,
+  CardContent,
+  CardDescription,
+  CardFooter,
+  CardHeader,
+  CardTitle,
+} from "@/components/ui/card"
+import { Button } from "@/components/ui/button"
+
+<Card>
+  <CardHeader>
+    <CardTitle>Title</CardTitle>
+  </CardHeader>
+  <CardContent>
+    <p>Content</p>
+  </CardContent>
+  <CardFooter>
+    <Button>Action</Button>
+  </CardFooter>
+</Card>
+```

+## Migration Guide Template
+
+```markdown
+# Migration Guide: [ComponentName]
+
+## Breaking Changes
+- Changed prop: `color` → `variant`
+- Removed prop: `size="medium"` (now default)
+- New required prop: `asChild` for composition
+
+## API Changes
+```tsx
+// Before
+<OldComponent color="primary" size="large" />
+
+// After
+<NewComponent variant="default" size="lg" />
+```
+
+## Styling Changes
+- Uses Tailwind classes instead of CSS modules
+- Theme variables now use CSS custom properties
+- Dark mode handled automatically
+
+## Usage Examples
+[Provide before/after examples]
+```
+
+## Example
+
+If the user says: `/migrate-component components/CustomButton.jsx`
+
+1. Read and analyze CustomButton.jsx
+2. Identify styling system used
+3. Create new button following shadcn patterns:
+   - Add CVA variants
+   - Convert styles to Tailwind
+   - Add proper TypeScript types
+   - Include forwardRef
+4. Test compatibility
+5. Provide migration guide
