About
The Clap Patterns skill equips Claude with specialized knowledge for building high-quality command-line tools in Rust using the Clap crate (v4+). It provides a library of implementation patterns covering both the declarative Derive API and the dynamic Builder API, ensuring that CLI tools are type-safe, user-friendly, and maintainable. By leveraging this skill, developers can quickly implement complex features like custom value validation, environment variable fallbacks, mutually exclusive argument groups, and sophisticated subcommand hierarchies with shared global options.
