+# Nuxt 4+ Development
+
+Progressive guidance for Nuxt 4+ projects with latest patterns and conventions.
+
+## When to Use
+
+Working with:
+
+- Server routes (API endpoints, server middleware, server utils)
+- File-based routing (pages, layouts, route groups)
+- Nuxt middleware (route guards, navigation)
+- Nuxt plugins (app extensions)
+- Nuxt-specific features (auto-imports, layers, modules)
+
+## Available Guidance
+
+Read specific files based on current work:
+
+- **[references/server.md](references/server.md)** - API routes, server middleware, validation (Zod), WebSocket, SSE
+- **[references/routing.md](references/routing.md)** - File-based routing, route groups, typed router, definePage
+- **[references/middleware-plugins.md](references/middleware-plugins.md)** - Route middleware, plugins, app lifecycle
+- **[references/nuxt-composables.md](references/nuxt-composables.md)** - Nuxt composables (useRequestURL, useFetch, navigation)
+- **[references/nuxt-components.md](references/nuxt-components.md)** - NuxtLink, NuxtImg, NuxtTime (prefer over HTML elements)
+- **[references/nuxt-config.md](references/nuxt-config.md)** - Configuration, modules, auto-imports, layers
+
+**For Vue composables:** See `vue` skill composables.md (VueUse, Composition API patterns)
+**For UI components:** use `nuxt-ui` skill
+**For database/storage:** use `nuxthub` skill
+**For content-driven sites:** use `nuxt-content` skill
+**For creating modules:** use `nuxt-modules` skill
+**For project scaffolding/CI:** use `personal-ts-setup` skill
+
+## Usage Pattern
+
+**Progressive loading - only read what you need:**
+
+- Creating API endpoint? → [references/server.md](references/server.md)
+- Setting up pages/routing? → [references/routing.md](references/routing.md)
+- Using composables/data fetching? → [references/nuxt-composables.md](references/nuxt-composables.md)
+- Adding middleware/plugins? → [references/middleware-plugins.md](references/middleware-plugins.md)
+- Configuring Nuxt? → [references/nuxt-config.md](references/nuxt-config.md)
+- Setting up CI/ESLint? → [references/project-setup.md](references/project-setup.md)
+
+**DO NOT read all files at once.** Load based on context:
+
+- Working in `server/` → read server.md
+- Working in `pages/` or `layouts/` → read routing.md
+- Using `useFetch`, `useRequestURL`, navigation → read nuxt-composables.md
+- Using `<a>`, `<img>`, `<time>` elements → read nuxt-components.md
+- Working in `middleware/` or `plugins/` → read middleware-plugins.md
+- Editing `nuxt.config.ts` → read nuxt-config.md
+
+## Nuxt 4 vs Older Versions
+
+**You are working with Nuxt 4+.** Key differences:
+
+| Old (Nuxt 2/3)    | New (Nuxt 4)                    |
+| ----------------- | ------------------------------- |
+| `<Nuxt />`        | `<NuxtPage />`                  |
+| `context.params`  | `getRouterParam(event, 'name')` |
+| `window.origin`   | `useRequestURL().origin`        |
+| String routes     | Typed router with route names   |
+| Separate layouts/ | Parent routes with `<slot>`     |
+
+**If you're unsure about Nuxt 4 patterns, read the relevant guidance file first.**
+
+## Latest Documentation
+
+**When to fetch latest docs:**
+
+- New Nuxt 4 features not covered here
+- Module-specific configuration
+- Breaking changes or deprecations
+- Advanced use cases

+## Token Efficiency
+
+Main skill: ~300 tokens. Each sub-file: ~800-1500 tokens. Only load files relevant to current task.
