This skill provides specialized guidance for implementing functional error handling in TypeScript using the fp-ts library. It enables developers to treat errors as values, ensuring that failure states are explicitly represented in function signatures. By utilizing patterns like Either for synchronous operations and TaskEither for asynchronous tasks, it eliminates 'try/catch spaghetti' and provides robust methods for error accumulation in complex workflows like form validation and API services.
