What problem does it solve?

This Skill addresses critical security vulnerabilities in Next.js applications, particularly within the App Router and Server Actions, ensuring data integrity and preventing common attack vectors.

Core Features & Use Cases

• Input Validation: Enforces strict data validation for all incoming data using Zod schemas.
• Data Boundary Enforcement: Prevents sensitive data leakage from server components to client components.
• Server-Side Security: Implements server-only markers and middleware for route protection.
• Use Case: Protect your Next.js application by ensuring all form submissions to Server Actions are validated, preventing unauthorized data modifications and security breaches.
