This skill equips Claude with specialized knowledge for architecting and implementing professional CLI applications in Rust. It enforces critical domain constraints such as proper error reporting to stderr, layered configuration management (CLI, env, files), and non-zero exit codes. By leveraging crates like clap, ratatui, and indicatif, it helps developers create type-safe argument parsers, interactive TUIs, and responsive progress indicators, ensuring production-grade user ergonomics and scriptability.
