# Go Coding Style > This file extends [common/coding-style.md](../common/coding-style.md) with Go specific content. ## Formatting - **gofmt** and **goimports** are mandatory — no style debates ## Design Principles - Accept interfaces, return structs - Keep interfaces small (1-3 methods) ## Error Handling Always wrap errors with context: ```go if err != nil { return fmt.Errorf("failed to create user: %w", err) } ``` ## Reference See skill: `golang-patterns` for comprehensive Go idioms and patterns.
