概要
This skill empowers Claude to automatically add Sorbet `sig` blocks to your Ruby codebase, enhancing type safety without the need for external RBI files. It follows a rigorous 5-step process that includes source analysis, type inference to eliminate `T.untyped`, and validation using the Sorbet type checker (`srb tc`). By enforcing best practices like `extend T::Sig` and avoiding unsafe type casts, it helps maintain a robust, type-safe Ruby environment while preserving existing file strictness levels and adhering to professional Ruby standards.
