Backend Code Skill

This skill handles backend service development, data processing, and integration.

When to use this skill

• When building APIs, workers, or microservices.
• When interacting with databases, caches, and message queues.
• When implementing business logic and validation rules.

Guidelines

• Validate and sanitize all incoming data at the API edge.
• Assume network calls and database queries will occasionally fail; implement retries and circuit breakers.
• Decouple business logic from the transport layer (e.g., Controllers should not contain complex logic).
• Log structured data (JSON) and ensure PII is masked.
