How does this skill handle user cancellation (Ctrl+C)?

It enforces global SIGINT handling and requires p.isCancel() checks after every prompt to ensure the CLI exits gracefully with appropriate codes without corrupting terminal state.

Why should I use Commander.js with @clack/prompts?

Commander.js excels at command structure and flag parsing, while Clack provides a superior interactive terminal UI. Together they create professional, user-friendly CLI experiences with clear navigation.

Does it support async operations in CLI actions?

Yes, it mandates the use of parseAsync() to ensure that asynchronous command actions propagate errors correctly and prevent the process from exiting prematurely before operations complete.

What is the configuration resolution order provided by this skill?

It follows a strict hierarchy: command-line flags take precedence, followed by environment variables, project-level config files, global user config, and finally hardcoded defaults.
