How does this skill improve Go code quality?

It enforces idiomatic Go patterns where errors are treated as values, ensuring that failures are handled explicitly, wrapped with context, and easily inspectable by calling functions.

Can it help me avoid common Go error mistakes?

Absolutely. It identifies and corrects issues like shadowing errors, ignoring Close() calls, using capital letters in error strings, and using equality checks instead of errors.Is.

Does it support modern Go error features?

Yes, it fully supports Go 1.13+ features including the %w formatting verb for wrapping and the errors package functions Is and As for navigating error chains.

When should I use custom error types instead of simple errors?

Use custom error types when you need to attach extra metadata to a failure, such as field names for validation or resource IDs for database lookups, which callers might need to access programmatically.

Does this skill provide guidance on using panic?

Yes, it defines strict rules for panic usage, reserving it for truly unrecoverable programmer errors and providing patterns for safe recovery at goroutine or request boundaries.

Implements idiomatic Go error handling strategies, wrapping patterns, and best practices for robust application development.

The Go Error Handling skill equips Claude with specialized knowledge to manage errors as first-class values in Go. It provides comprehensive guidance on creating sentinel errors, implementing custom error types with the Unwrap interface, and using modern error wrapping techniques with the %w verb. By applying these patterns, the skill helps developers maintain clear error chains, correctly utilize errors.Is and errors.As for inspection, and avoid common pitfalls like silent failures or inappropriate use of panic. It is an essential resource for building maintainable, production-grade Go services that communicate failure context effectively.
