Does it handle configuration management?

Yes, it includes patterns for integrating with Viper for config files (YAML, JSON) and automatic environment variable binding.

Is it suitable for enterprise-grade tools?

Yes, it is specifically modeled after high-scale production tools like Hugo and kubectl, ensuring reliability, scalability, and maintainability.

What CLI structures are supported by this skill?

It supports five distinct architectures: simple (single command), flat (root with subcommands), nested (hierarchical/kubectl-style), plugin (extensible), and hybrid.

Can I validate command arguments automatically?

Absolutely, it provides patterns for custom validation functions, exact argument counts, range-based validation, and shell completion.

How does it help with user experience?

It facilitates the creation of command groups for organized help menus, standardized error handling (RunE), and automated completion support.
