SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires zod.

What problem does it solve?

This skill provides battle-tested patterns for securing Next.js API routes, addressing critical vulnerabilities like abuse, data leaks, and unauthorized access. It simplifies the implementation of rate limiting, security headers, and robust validation, ensuring your APIs are resilient and protect sensitive data.

Core Features & Use Cases

Rate Limiting: Implements robust rate limiting to prevent abuse and Denial-of-Service (DoS) attacks on API endpoints.
Security Headers & CORS: Configures essential HTTP security headers (HSTS, X-Frame-Options, CSP) and proper Cross-Origin Resource Sharing (CORS) for API responses.
Protected API Route Pattern: Provides a comprehensive template for securing API routes with authentication, validation, sanitization, and error handling.
Use Case: A developer is building a critical API endpoint that handles sensitive user data. They activate this skill to get immediate, secure code for rate limiting, authentication, input validation, and applying security headers, ensuring the endpoint is protected against common web attacks.

Quick Start

Use the api-security-patterns skill to implement rate limiting and security headers for a new API route.
