Are security best practices included?

Absolutely. The skill provides patterns for auth wrappers, rate-limiting middleware, and cryptographic signature verification for webhooks.

How does this skill handle input validation?

It utilizes Zod for schema-based validation, ensuring that all API inputs are type-safe and transformed correctly before reaching your business logic.

What frameworks does this skill support?

The patterns are designed to be framework-agnostic but include specific implementations for Next.js, Express, and Fastify using TypeScript.

Does it support advanced database features?

Yes, it includes specialized logic for cursor-based pagination, which is more performant than offset pagination for large-scale applications.

API Development

Implements secure, type-safe, and scalable server-side API patterns for modern web frameworks like Next.js and Express.

About

This skill equips Claude with standardized implementation patterns for building professional-grade APIs that prioritize security and maintainability. It provides ready-to-use boilerplate for Next.js Server Actions, Express/Fastify REST endpoints, and Zod-based validation. Beyond basic CRUD, it includes advanced architectural patterns for cursor-based pagination, multi-strategy API versioning, token-bucket rate limiting, and robust webhook delivery systems with retry logic and signature verification. It is ideal for developers looking to accelerate backend development while adhering to industry best practices.
