Complete shadcn/ui component management for adding, searching, fixing, styling, and composing UI.

## Core Capabilities

- Adding, updating, and debugging components using CLI commands
- Applying presets and managing project configurations
- Composing UI using existing components rather than custom markup
- Enforcing styling and structural best practices

## Critical Rules

### Styling

- Use semantic colors (`bg-primary`, not `bg-blue-500`)
- Apply `gap-*` for spacing, never `space-x-*` or `space-y-*`
- Use `size-*` when width equals height
- Apply `cn()` for conditional classes
- Avoid manual `dark:` overrides or manual `z-index`

### Forms

- Structure forms with `FieldGroup` + `Field`, never raw divs
- Use `ToggleGroup` for 2–7 option sets

### Components

- Keep items inside their containers (`SelectItem` → `SelectGroup`)
- Always include accessibility elements (`DialogTitle`, `AvatarFallback`)
- Use `data-icon` for button icons, no sizing classes on icons
- Compose with `Spinner` instead of pseudo-loading states via CSS

### Icons

- Pass icons as objects, never string lookups
- Do not add size classes to icon components — use `data-icon`

## Workflow

1. Get your project context (run `npx shadcn@latest info` if needed)
2. Check installed components before adding new ones
3. Run `npx shadcn@latest docs <component>` for current APIs
4. Use `--dry-run` and `--diff` before updating existing components
5. Verify all added files match the critical rules above

## Key Project Context Fields

Your project context includes:
- `isRSC` — whether React Server Components are enabled
- `packageManager` — npm, pnpm, yarn, bun
- `iconLibrary` — lucide-react, radix-icons, etc.
- `base` — radix or base registry
- `aliases` — path aliases for components, utils, etc.
- `resolvedPaths` — actual filesystem paths for each alias

## Common CLI Commands

```bash
# Add a component
npx shadcn@latest add button

# Check what's installed
npx shadcn@latest info

# View component documentation
npx shadcn@latest docs button

# Preview changes before applying
npx shadcn@latest update button --dry-run
npx shadcn@latest update button --diff
```

## Multiple Registries

The skill supports multiple registries and automatically injects project context when running CLI commands to give accurate, project-specific guidance.

## Installation

```bash
npx skills add https://github.com/shadcn/ui --skill shadcn
```
