What is the Go Error Handling skill?

It is a specialized capability for Claude Code that provides expert guidance and implementation patterns for managing errors idiomatic to the Go programming language.

Does this skill support the %w wrapping verb?

Yes, it prioritizes using %w with fmt.Errorf to ensure that error chains remain inspectable via the standard library errors package.

Can it help with custom error types?

Absolutely. It provides patterns for creating structured error types that include specific metadata while correctly implementing the error interface.

How does it handle sentinel errors?

The skill provides guidance on defining package-level sentinel errors and using errors.Is to check for them safely without breaking encapsulation.

API Development

Implements idiomatic Go error handling patterns including wrapping, custom types, and inspection to ensure robust and maintainable backend code.

The Go Error Handling skill provides Claude with expert knowledge of Go's unique error management ecosystem, enabling the automated application of modern best practices. It guides the implementation of contextual wrapping using the %w verb, the creation of structured custom error types, and the correct use of errors.Is and errors.As for deep error inspection. This skill is essential for developers looking to eliminate common mistakes like ignored errors or lost type context while ensuring that error chains are handled consistently across package boundaries.
