func handleCommand(ctx context.Context, args []string) error { // Creating a new context string object cs := kbcli.NewContextString("handleCommand") // Adding the context string to the context object ctx = kbcli.NewContext(ctx, cs) // Logging a message with the context string kbcli.Log(ctx, "handling command: %s", args) // ... other command handling logic ... }In this example, a new context string object is created with the label "handleCommand". This label can then be added to the existing context object by calling `kbcli.NewContext` with the original context object and the new context string object as the parameters. Finally, the `kbcli.Log` function is called with the modified context object to log a message that includes the context string. Overall, the go github.com.keybase.cli package provides a useful set of logging and messaging tools that can improve the developer experience when building command-line interfaces.
