Implements type-safe error handling in TypeScript using fp-ts patterns like Either and TaskEither to replace unpredictable try/catch blocks.

This skill provides a structured approach to managing errors as values within TypeScript applications by leveraging the fp-ts library. It guides developers through replacing traditional exceptions with explicit, type-checked failure states, ensuring that errors are handled at compile-time rather than runtime. By covering synchronous Result patterns, asynchronous TaskEither workflows, and advanced error accumulation for validations, this skill helps create more predictable, maintainable, and robust codebases.
