Go Error Handling

What it does

This skill provides Go code snippets and explanations focused on robust error handling. It demonstrates techniques such as using custom error types, wrapping errors with context, and implementing graceful error recovery strategies within Go applications. The goal is to improve the reliability and maintainability of Go programs by effectively managing potential failure scenarios.

When to use it

• Debugging existing Go code: When encountering unexpected behavior or crashes in a Go application, this skill can help analyze and fix error handling logic.
• Writing new Go services: To ensure proper error propagation and logging when building backend systems or APIs.
• Refactoring legacy Go projects: Improve the robustness of older Go codebases by introducing more structured and informative error handling practices.
• Learning best practices in Go: For developers looking to deepen their understanding of how to write resilient and maintainable Go applications.

Key capabilities

• Custom Error Types
• Error Wrapping with Context
• Graceful Error Recovery
• Detailed Error Logging

Example prompts

• "Show me an example of wrapping a standard library error in Go."
• "How can I create a custom error type in Go?"
• "Give me a code snippet demonstrating how to handle errors gracefully in a Go HTTP server."

Tips & gotchas

This skill assumes basic familiarity with the Go programming language. While it provides examples, understanding the underlying principles of error handling is crucial for effective application.
