What is the difference between Exceptions and Result types?

The skill provides guidance on using Exceptions for unexpected conditions and Result types for explicit, functional error handling in languages like Rust or TypeScript.

How does this improve debugging?

By implementing structured custom error classes and proper error wrapping, it ensures that stack traces and error messages contain the context necessary to solve issues quickly.

When should I use this skill?

Use it when designing new APIs, implementing retry logic, debugging complex production issues, or improving application reliability.

Which programming languages are supported?

This skill provides specialized patterns and code examples for Python, TypeScript/JavaScript, Rust, and Go.

Does it cover distributed systems?

Yes, it includes universal patterns like Circuit Breakers and exponential backoff to prevent cascading failures in microservice architectures.
