How does it handle input validation?

It utilizes the Commander.js Option class and custom argument parsers to validate data types, choices, and mandatory flags before execution.

Does this skill support TypeScript?

Yes, it includes specialized TypeScript templates and configurations to ensure type safety across your CLI commands and options.

Is it compatible with other Node.js libraries like Inquirer or Chalk?

Yes, the skill includes integration recipes for combining Commander.js with Inquirer for interactive prompts and Chalk for styled terminal output.

What version of Commander.js is this optimized for?

These patterns are optimized for Commander.js v12 and above, taking advantage of the latest framework features.

Can I build nested subcommands like those found in Git?

Absolutely. The skill provides specific patterns and logic for creating complex, multi-level command hierarchies.
