Use when building styled UI with @nuxt/ui v4 components (Button, Modal, Form, Table, etc.) - provides ready-to-use components with Tailwind Variants theming. Use vue skill for raw component patterns, reka-ui for headless primitives.
Nuxt UI v4
Component library for Vue 3 and Nuxt 4+ built on Reka UI (headless) + Tailwind CSS v4 + Tailwind Variants.
Current stable version: v4.4.0 (January 2026)
When to Use
- Installing/configuring @nuxt/ui
- Using UI components (Button, Card, Table, Form, etc.)
- Customizing theme (colors, variants, CSS variables)
- Building forms with validation
- Using overlays (Modal, Toast, CommandPalette)
- Working with composables (useToast, useOverlay)
For Vue component patterns: use vue skill
For Nuxt routing/server: use nuxt skill
Available Guidance
| File | Topics |
|---|---|
| references/installation.md | Nuxt/Vue setup, pnpm gotchas, UApp wrapper, module options, prefix, tree-shaking |
| references/theming.md | Semantic colors, CSS variables, app.config.ts, Tailwind Variants |
| references/components.md | Component index by category (125+ components) |
| components/*.md | Per-component details (button.md, modal.md, etc.) |
| references/forms.md | Form components, validation (Zod/Valibot), useFormField |
| references/overlays.md | Toast, Modal, Slideover, Drawer, CommandPalette |
| references/composables.md | useToast, useOverlay, defineShortcuts, useScrollspy |
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
Quick Reference
// nuxt.config.ts
export default defineNuxtConfig({
modules: ['@nuxt/ui'],
css: ['~/assets/css/main.css']
})
/* assets/css/main.css */
@import 'tailwindcss';
@import '@nuxt/ui';
<!-- app.vue - UApp wrapper required -->

cache-components
Expert guidance for Next.js Cache Components and Partial Prerendering (PPR). **PROACTIVE ACTIVATION**: Use this skill automatically when working in Next.js projects that have `cacheComponents: true` in their next.config.ts/next.config.js. When this config is detected, proactively apply Cache Components patterns and best practices to all React Server Component implementations. **DETECTION**: At the start of a session in a Next.js project, check for `cacheComponents: true` in next.config. If enabled, this skill's patterns should guide all component authoring, data fetching, and caching decisions. **USE CASES**: Implementing 'use cache' directive, configuring cache lifetimes with cacheLife(), tagging cached data with cacheTag(), invalidating caches with updateTag()/revalidateTag(), optimizing static vs dynamic content boundaries, debugging cache issues, and reviewing Cache Component implementations.

component-refactoring
Refactor high-complexity React components in Dify frontend. Use when `pnpm analyze-component --json` shows complexity > 50 or lineCount > 300, when the user asks for code splitting, hook extraction, or complexity reduction, or when `pnpm analyze-component` warns to refactor before testing; avoid for simple/well-structured components, third-party wrappers, or when the user explicitly wants testing without refactoring.
