The **@ash-framework/argument-error** package provides a tiny utility class for generating clear, descriptive error messages when a function or class receives an invalid argument. By supplying the context (e.g., class name), the offending argument’s name, and an optional detail message, developers get a ready‑to‑throw `ArgumentError` that formats a helpful message for end‑users. It is targeted at JavaScript/Node developers who want consistent, readable argument‑validation errors in their libraries or applications.
