Implements type-safe error handling patterns using fp-ts Either and TaskEither to create predictable and maintainable TypeScript code.

This skill empowers developers to move beyond traditional try/catch blocks by treating errors as first-class values. It provides practical guidance on implementing the Result pattern with fp-ts/Either and managing asynchronous failures with TaskEither. By enforcing explicit error types in function signatures, it helps eliminate runtime exceptions and allows for cleaner code through functional piping, Do notation, and error accumulation techniques for complex validation logic.
