Alternative: Direct Prompt Integration

If you're using Claude through the web interface or API, you can activate this skill by including the following in your system prompt:

You are an expert in TypeScript, Node.js, Next.js App Router, React, 
Shadcn UI, Radix UI, Supabase, Tailwind, and Vercel AI SDK.

Use Cases: Where This Claude Skill Excels

Use Case 1: Building a Real-Time Authentication System with Supabase

Scenario: You're developing a multi-tenant SaaS application and need to implement secure authentication with role-based access control.

Example Prompt:

Using Next.js 14 App Router and Supabase, help me implement a complete 
authentication system with email/password signup, magic link login, and 
protected API routes. Include TypeScript types for user roles (admin, user, viewer) 
and show how to create middleware that checks permissions before allowing access 
to specific routes.

What the Skill Delivers:

• Complete authentication flow using Supabase Auth
• Type-safe middleware implementation with Next.js 14
• Row-level security (RLS) policies for Supabase
• Reusable auth hooks with proper TypeScript typing
• Integration with Shadcn UI components for login forms

Use Case 2: Creating a Scalable API with Server Actions and Database Optimization

Scenario: You need to build a performant API layer that handles complex data relationships while maintaining type safety across your entire stack.

Example Prompt:

I'm building a project management tool with Next.js and Supabase. Create 
server actions for CRUD operations on projects, tasks, and comments with 
proper relationships. Include TypeScript types, error handling, optimistic 
updates on the client, and show how to use Supabase's query builder efficiently. 
Also implement real-time subscriptions for collaborative features.

What the Skill Delivers:

• Type-safe server actions using Next.js App Router patterns
• Optimized Supabase queries with proper joins and indexes
• Zod schemas for runtime validation
• Real-time subscription setup with TypeScript types
• Error boundary implementation with React
• Optimistic UI updates using React hooks

Use Case 3: Implementing AI-Powered Features with Vercel AI SDK

Scenario: You want to integrate AI capabilities into your application, such as content generation, smart search, or chatbot functionality.

Example Prompt:

Help me integrate the Vercel AI SDK into my Next.js app to create an AI-powered 
content assistant. The feature should stream responses, save conversation history 
to Supabase, and use React Server Components. Include proper TypeScript types, 
error handling, and a beautiful UI using Shadcn components with Tailwind styling.

What the Skill Delivers:

• Streaming AI responses with Vercel AI SDK
• Server-side API routes with edge runtime support
• Supabase integration for conversation persistence
• Type-safe chat UI components using Shadcn/Radix
• Responsive design with Tailwind CSS utilities
• Rate limiting and authentication integration
