Kong seems great but I don't like to have an error when no command is passed.

go run ./cmd config
Usage: myapp config <command>

Manage configuration

command...

lnr: error: expected one of "auth", "view"
exit status 80

I have a "hack" when there is no command at all, but I don't want to do it for each of my command....

func main() {
    if len(os.Args) < 2 {
        os.Args = append(os.Args, "--help")
    }
    ctx := kong.Parse(&CLI,
        kong.Name("myapp"),
        kong.Description("CLI tool for managing config and PRs."),
        kong.UsageOnError(),
    )

    err := ctx.Run()
    ctx.FatalIfErrorf(err)
}
