What languages are supported for CLI development?

This skill provides specific implementation guides for Python using Typer, Go using Cobra, and Rust using the clap framework.

Can I use this for complex subcommand structures?

Yes, it provides patterns for flat, grouped, and nested command hierarchies suitable for large-scale tools similar to kubectl or gcloud.

Can it help with software distribution?

Yes, it covers packaging strategies for major platforms including PyPI for Python, Homebrew for Go binaries, and Cargo for Rust applications.

Does it handle configuration management and secrets?

The skill implements a standard precedence model including CLI flags, environment variables, and multi-level config files, along with best practices for secret management.

How does it help with user experience (UX)?

It includes patterns for interactive features like progress bars, confirmation prompts, colored output, and automated shell completion generation for Bash and Zsh.
