go

name	go
description	Go programming conventions, error handling, concurrency patterns, and tooling. Use when writing or editing .go files, working with go.mod, goroutines, channels, or Go interfaces.

Go

• Use gofmt formatting conventions.
• Prefer explicit error handling over panics.
• Use context.Context for cancellation and deadlines.
• Avoid global mutable state; prefer dependency injection.
• Interfaces should be small (1-3 methods) and defined at the call site.
• Use defer for resource cleanup.
• Goroutines must have clear lifecycle management.
• Channels close from the sender side.
• Use go build, go test, go vet for verification.
