Go Error Handling Mastery

About

This skill empowers developers to master Go's idiomatic error handling ecosystem, moving beyond simple checks to professional patterns like error wrapping with context, custom error type assertions, and structured multi-error management. It provides a comprehensive framework for building robust, observable Go applications by ensuring errors are enriched with context and handled according to modern Go 1.13+ standards and industry best practices, making it essential for backend engineers and system architects.
