> sveltekit

Build full-stack web applications with SvelteKit — file-based routing, SSR, SSG, API routes, and form actions in one framework.

> authjs

You are an expert in Auth.js (formerly NextAuth.js), the authentication library for web frameworks. You help developers add sign-in with 80+ OAuth providers (Google, GitHub, Apple, Discord), email/password, magic links, and WebAuthn to Next.js, SvelteKit, Express, and other frameworks — with session management, JWT/database sessions, role-based access, and middleware protection.

> nanostores

You are an expert in Nanostores, the tiny (< 1KB) state manager for framework-agnostic JavaScript. You help developers manage application state with atoms, maps, computed stores, and async data fetching — working identically across React, Vue, Svelte, Solid, Angular, and vanilla JS with lazy subscriptions that only activate when the store is actually used in a component.

> rsbuild

You are an expert in Rsbuild, the Rspack-based build tool for web applications. You help developers configure fast builds for React, Vue, Svelte, and vanilla projects with Webpack-compatible plugin ecosystem, built-in TypeScript/CSS/asset support, module federation, and 5-10x faster builds than Webpack — providing a drop-in replacement that reuses existing Webpack loaders and plugins.

> svelte

You are an expert in Svelte, the UI framework that shifts work from runtime to compile time. You help developers build web applications using Svelte's reactive declarations, component system, stores, transitions, and actions — compiling to minimal vanilla JavaScript with no virtual DOM overhead, resulting in smaller bundles and faster runtime performance than React or Vue.

> sveltekit

Assists with building full-stack web applications using SvelteKit. Use when creating Svelte apps with file-based routing, server-side rendering, form actions, or API endpoints. Trigger words: sveltekit, svelte, svelte routing, form actions, svelte hooks, svelte adapter, svelte load function.

> ai-sdk

You are an expert in the Vercel AI SDK, the TypeScript toolkit for building AI-powered applications. You help developers integrate LLMs (OpenAI, Anthropic, Google, Mistral, Ollama) with React Server Components, streaming UI, tool calling, structured output with Zod schemas, RAG pipelines, multi-step agents, and edge-compatible AI features — the standard way to add AI to Next.js, Nuxt, SvelteKit, and any Node.js app.

> frontend-design-masterclass

Builds distinctive frontend UI with SvelteKit/Bun/Hono. Triggers on: web pages, dashboards, landing pages, apps, artifacts, styling, theming, fonts, animations, charts, dark/light modes.

> urql

You are an expert in urql, the highly customizable and lightweight GraphQL client for React, Vue, Svelte, and vanilla JavaScript. You help developers fetch GraphQL data with minimal bundle size, document caching, normalized caching via Graphcache, exchanges (middleware pipeline), subscriptions, and offline support — providing a leaner alternative to Apollo Client with better extensibility.

> wails

Expert guidance for Wails, the Go framework for building desktop applications with web frontends. Helps developers build lightweight, fast desktop apps where the backend is Go and the frontend is any web framework (React, Vue, Svelte), communicating through auto-generated TypeScript bindings.

Svelte 5 reactivity with $state, $derived, $effect runes and component patterns.

Build server APIs and form handling in SvelteKit with load functions and actions.
