Which programming languages does this skill support?

This skill provides specific, idiomatic implementation patterns for Python, TypeScript/JavaScript, Rust, and Go.

Does it include guidance on user-facing error messages?

Yes, it focuses on creating structured error details that benefit both developer debugging and end-user clarity.

How does this improve API design?

It provides templates for standardized error objects, ensuring your API communicates failures consistently across different endpoints.

What is the difference between Exceptions and Result types in this skill?

The skill helps you decide between traditional control-flow exceptions for unexpected errors and explicit Result types for expected domain-level failures.

Can this skill help with microservices reliability?

Yes, it includes advanced patterns like Circuit Breakers and exponential backoff retries designed to prevent cascading failures in distributed systems.
