Can it help with database performance issues?

Yes, it provides specific implementation patterns for preventing N+1 queries, utilizing SQL transactions, and selecting only necessary columns to reduce overhead.

When should I activate this skill in Claude?

Activate it when you are designing new API endpoints, structuring your project's folder hierarchy, or adding complex features like caching and background jobs.

Which frameworks are supported by this skill?

While the architectural principles are universal, the skill is optimized with specific examples for Node.js, Express, and Next.js API routes.

Does it handle API security and authentication?

Absolutely. It includes patterns for JWT token validation, Role-Based Access Control (RBAC), and implementing rate limiters to protect endpoints.

What does the Backend Patterns skill do?

It provides expert guidance and boilerplate code for professional backend structures including repository layers, service layers, and request-processing middleware.
