Security Review

Analyze the codebase for security vulnerabilities:

1. Authentication & Authorization

   • Verify Clerk auth is properly configured on protected routes
   • Check middleware.ts for proper route protection
   • Ensure API routes validate user sessions

2. API Security

   • No exposed API keys or secrets in client-side code
   • Environment variables properly prefixed with NEXT_PUBLIC_
   • Rate limiting on public endpoints
   • Input validation with Zod on all API routes

3. Injection Risks

   • SQL injection (Supabase queries use parameterized queries)
   • XSS risks in user-generated content
   • Prompt injection in AI features

4. Data Protection

   • .env files are gitignored
   • No sensitive data in client-side code
   • Proper CORS configuration
   • HTTPS enforcement in production

5. AI-Specific Concerns

   • User input sanitization before AI prompts
