# Effective Go Apply best practices and conventions from the official [Effective Go guide](https://go.dev/doc/effective_go) to write clean, idiomatic Go code. ## When to Apply Use this skill automatically when: - Writing new Go code - Reviewing Go code - Refactoring existing Go implementations ## Key Reminders Follow the conventions and patterns documented at https://go.dev/doc/effective_go, with particular attention to: - **Formatting**: Always use `gofmt` - this is non-negotiable - **Naming**: No underscores, use MixedCaps for exported names, mixedCaps for unexported - **Error handling**: Always check errors; return them, don't panic - **Concurrency**: Share memory by communicating (use channels) - **Interfaces**: Keep small (1-3 methods ideal); accept interfaces, return concrete types - **Documentation**: Document all exported symbols, starting with the symbol name ## References - Official Guide: https://go.dev/doc/effective_go - Code Review Comments: https://github.com/golang/go/wiki/CodeReviewComments - Standard Library: Use as reference for idiomatic patterns
