Build production-grade REST APIs with Go and Gin. This skill covers the 80% of patterns you need daily: server setup, routing, request binding, response formatting, and error handling.

Use internal/ for code that must not be imported by other modules. Use pkg/ for reusable middleware and utilities.

Architecture note: In clean architecture, domain entities should not carry json or binding tags. Use separate request/response DTOs in the delivery layer. See golang-gin-clean-arch Golden Rule 4.

Build REST APIs with Go Gin framework. Covers routing, handler patterns, request binding/validation, middleware chains, error handling, security headers (OWASP), CORS, timeout middleware, and layered project structure. Use when creating Go web servers, REST endpoints, HTTP handlers, or working with the Gin framework. Also activate when the user mentions Gin routes, middleware, JSON responses, request parsing, or API structure in Go. Source: henriqueatila/golang-gin-best-practices.
