name: Backend API Responses description: Structure API responses with consistent envelopes, appropriate HTTP status codes, and standardized error formats. Use this skill when implementing response handlers, formatting API response data, creating error response structures, implementing validation error responses, setting up pagination response formats, defining response DTOs or serializers, implementing HTTP status code logic, creating response middleware or interceptors, formatting success and error response envelopes, sanitizing response data to prevent sensitive data leakage, implementing field-level validation error responses, or working with response transformation logic. Use when writing controller return statements, response serializers, error handlers, or any code that formats and returns data to API clients.

When to use this skill

• When implementing response handlers or formatters
• When creating or updating error response structures
• When implementing validation error responses with field-level details
• When setting up pagination response formats (limit/offset or cursor-based)
• When defining response DTOs, serializers, or data transfer objects
• When implementing HTTP status code selection logic
• When creating response middleware, interceptors, or transformers
• When formatting success response envelopes
• When sanitizing response data to prevent sensitive information leakage
• When implementing consistent error code and message formats
• When working with controller return statements or response builders
• When creating response helper functions or utilities
• When removing stack traces or internal details from production responses
