Idiomatic Go code for microservices requires following community best practices for error handling, concurrency patterns, and package organization to ensure applications are robust, readable, and easy to maintain. This Skill guides you in applying these patterns to new code, refactoring, and module design.

The best way to handle errors and concurrency in Go is to use proper error wrapping with context and implement safe worker pools. This approach prevents goroutine leaks and avoids using panic for control flow, which are common anti-patterns that cause fragile and hard-to-maintain applications.

To refactor existing Go code to follow best practices, you should review your current implementation against idiomatic patterns. This Skill helps identify potential concurrency issues, improper error handling, and suboptimal struct or interface design to reduce technical debt and improve team collaboration.

Package design affects Go application maintainability by enforcing clean package structure and proper interface organization. Following idiomatic Go patterns for package design prevents non-idiomatic and bug-prone code, ensuring your application scales effectively without accumulating technical debt.

Yes, you can use this Skill for Go code review on your team. It explicitly calls out common Go mistakes like naked returns in long functions, goroutine leaks, and using panic for control flow, helping engineering teams identify potential issues and enforce best practices during reviews.

You should avoid naked returns and panic for control flow in Go because they are anti-patterns that make code fragile and hard to read. This Skill identifies these mistakes to help you write robust, idiomatic code that properly handles errors and concurrency without costly bugs.
