Practical Error Handling with fp-ts

Name: fp-errors
Author: sickn33

This skill teaches you how to handle errors without try/catch spaghetti. No academic jargon - just practical patterns for real problems.

The core idea: Errors are just data. Instead of throwing them into the void and hoping someone catches them, return them as values that TypeScript can track.

Detailed Guide

Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

When to Use

You need to replace exception-heavy code with Either or TaskEither.
The task involves validation, domain errors, or clearer error contracts in TypeScript.
You want pragmatic fp-ts error-handling guidance for real application code.

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
