Which programming languages does this skill support?

While the core implementation patterns are illustrated in TypeScript, the architectural concepts like Repository patterns and JWT flows are applicable to most modern backend languages.

Does it include security best practices?

Yes, it provides robust patterns for JWT-based authentication, secure refresh token handling, and role-based access control (RBAC) via middleware.

What is the Backend API Patterns skill?

It is a specialized capability for Claude Code that provides domain-specific guidance and implementation patterns for building secure, scalable, and maintainable backend services.

How does this skill help with database performance?

The skill includes specific patterns for avoiding N+1 query problems through eager loading, implementing cursor-based pagination, and utilizing the cache-aside pattern.
