error-codes-skill

What problem does it solve?

Managing error codes and delivering consistent error responses across Go services is error-prone and leads to ambiguous failures. This Skill provides a centralized scheme for error codes, error constructors, and a middleware-friendly pattern to ensure uniform responses.

Core Features & Use Cases

• Error code definitions: central constants for common and business errors.
• Unified responses: standard error payloads across handlers and services.
• Middleware integration: reusable middleware to map errors to HTTP responses.

Quick Start

• Create a shared error_codes.go with business and generic error constants.
• Add a middleware that converts errors into a standardized JSON response.
