Where should configuration files be stored according to these patterns?

The skill recommends using a hidden directory in the user's home folder (e.g., ~/.battery) to store JSON-based configuration and credentials.

What libraries does this skill utilize for CLI structure?

This skill focuses on Commander.js for command structure, Chalk for terminal styling, Ora for spinners, and @inquirer/prompts for interactive user input.

Does it support interactive user input?

Yes, it includes patterns for various input types including basic text, secure passwords, multiple-choice selections, and boolean confirmations.

Can I use these patterns for non-Battery projects?

While designed for the Battery hosting platform, these patterns are general-purpose and highly effective for any Node.js-based CLI tool.

How does this skill help with error handling?

It provides a standardized ExitCode mapping and an error display pattern that handles causes, stack traces in debug mode, and graceful SIGINT shutdowns.
