What problem does it solve?

This Skill eliminates repetitive boilerplate code for input validation in Next.js API routes, ensuring type safety and consistent error handling.

Core Features & Use Cases

• Automatic Zod Validation: Integrates Zod schemas for seamless input validation of query parameters or request bodies.
• Type Safety: Provides fully typed input data to your API handlers.
• Consistent Error Handling: Standardizes error responses for validation failures and internal server errors.
• Use Case: When building a Next.js API endpoint that accepts user search queries and pagination parameters, this Skill ensures the input is correctly formatted and typed before your business logic executes.

Quick Start
