The YAMLScript skill empowers Claude to act as a domain expert in the YAMLScript programming language, which brings functional programming power to YAML. It facilitates a structured workflow where logic is first verified in Clojure and then translated into idiomatic YAMLScript using specific style rules, such as dot-chaining, advanced string interpolation, and Do What I Mean (DWIM) argument placement. This skill is essential for developers building executable YAML configurations, CLI tools, or data-driven applications that require the readability of YAML combined with the robust logic of a Lisp-based language.
