How does this skill help with argument parsing?

The skill provides patterns for using the clap crate's derive macros to create type-safe, hierarchical argument and subcommand structures automatically.

What is the recommended configuration priority for CLI tools?

It enforces a standard hierarchy where CLI arguments override environment variables, which in turn override configuration files and default values.

Does this skill support interactive terminal features?

Yes, it includes guidance for integrating interactive prompts with dialoguer, progress bars with indicatif, and full TUIs with ratatui.

How are errors handled for shell script compatibility?

The skill ensures that all errors are directed to stderr and results in non-zero exit codes, making the tools reliable for use in automated pipelines.

Developer Tools

Streamlines the creation of robust, ergonomic Rust command-line interfaces using industry-standard libraries and implementation patterns.

The domain-cli skill provides a comprehensive framework for building professional terminal applications in Rust by enforcing critical domain constraints and design implications. It guides developers through implementing standard I/O best practices, layered configuration precedence (CLI > Env > File), and type-safe argument parsing using the clap crate. By integrating best-in-class tools like ratatui for TUIs and indicatif for progress tracking, this skill ensures that CLI tools are not only functional but also ergonomic, scriptable, and production-ready with proper error propagation and exit code management.
