Why Go Works Well for CLIs
Go produces static binaries, starts quickly, and has a strong standard library. Those traits make it a practical language for internal tools and user-facing command-line applications.
Command Structure
Use a command tree when the tool has more than one workflow. Keep command names direct, keep flags predictable, and make help output useful enough that users do not need to read source code.
package main
import "fmt"
func main() {
fmt.Println("ship it carefully")
}Release Flow
Automate builds for macOS, Linux, and Windows. Publish checksums, keep changelogs concise, and treat breaking flag changes as real API changes.
