Loading Files

Consider loading these reference files based on your task:

• [ ] references/installation.md - if installing or configuring @nuxt/ui
• [ ] references/theming.md - if customizing theme, colors, or Tailwind Variants
• [ ] references/components.md - if browsing component index or finding components by category
• [ ] references/forms.md - if building forms with validation (Zod/Valibot)
• [ ] references/overlays.md - if using Toast, Modal, Slideover, Drawer, or CommandPalette
• [ ] references/composables.md - if using useToast, useOverlay, or other composables

DO NOT load all files at once. Load only what's relevant to your current task.

Key Concepts

| Concept | Description | | ----------------- | ---------------------------------------------------------- | | UApp | Required wrapper component for Toast, Tooltip, overlays | | Tailwind Variants | Type-safe styling with slots, variants, compoundVariants | | Semantic Colors | primary, secondary, success, error, warning, info, neutral | | Reka UI | Headless component primitives (accessibility built-in) |

For headless component primitives (API details, accessibility patterns, asChild): read the reka-ui skill
