domain-cli

What problem does it solve?

This skill helps developers implement and enforce consistent domain constraints when building command-line tools, ensuring predictable UX, clear error handling, and reliable configuration behavior.

Core Features & Use Cases

• Domain-rule mapping to CLI design implications (argument parsing, subcommands, help messages) for maintainable and intuitive interfaces.
• Config precedence handling (CLI args > env vars > config file) with clear error reporting and predictable behavior.
• Practical use case: designing a Rust CLI with Clap derive, proper subcommands, and robust exit semantics for real-world tooling.

Quick Start

Review domain constraints, translate them into your CLI design, implement argument parsing with Clap, apply layered configuration, and verify with tests.
