What programming languages does this skill support?

While the skill defaults to Python (argparse, Click, Typer), the core design principles, POSIX conventions, and architecture patterns can be applied to any language used for CLI development.

Can it help me design complex subcommand structures?

Yes, the skill is specifically designed to handle both simple single-command tools and complex CLI applications with nested subcommands and shared global options.

Does it follow standard UNIX conventions?

Absolutely. It enforces POSIX argument styles, standard help formats, proper use of stdout for data and stderr for errors, and conventional exit codes.

How does this skill handle input validation?

It provides patterns for strict argument type validation, explicit handling of required versus optional arguments, and managing mutually exclusive options.
