Can it handle multiple errors at once?

Yes, it includes specific patterns for using errors.Join to collect and return multiple independent errors, which is ideal for validation tasks.

How does it improve overall Go code quality?

By enforcing strict anti-patterns such as 'don't log and return' and 'don't use string matching,' it ensures your error handling is consistent, performant, and easy to maintain.

Does it support HTTP API development?

Absolutely. It features a dedicated pattern for mapping internal domain errors to appropriate HTTP status codes and JSON responses at the package boundary.

How does this skill help with Go error wrapping?

It provides strict rules for using fmt.Errorf with the %w verb, ensuring that useful context is added to an error chain while maintaining the ability to unwrap the root cause.

API 개발

Implements idiomatic, robust error handling patterns for Go projects including wrapping, sentinel errors, and HTTP mapping.

This skill provides a comprehensive framework for Go error management, guiding developers through the selection and implementation of the most appropriate error patterns. It covers everything from simple error wrapping with fmt.Errorf and the %w verb to advanced custom error types and multi-error collection using errors.Join. By adhering to a structured decision framework, the skill ensures that errors are handled gracefully at the right level of abstraction, facilitating better debugging and more reliable API responses while strictly avoiding common anti-patterns like panics or redundant logging.
