What are the best practices for error handling in Go applications?

As I continue to build applications in Go, I've been reflecting on how vital effective error handling is to robust software. Go's approach to errors, with its explicit return values, is quite different from other languages that rely on exceptions. I'm curious about the best practices the community has developed for managing errors in Go.

How do you structure your error handling?
Do you use custom error types, and if so, what patterns have you found to be the most useful?

Additionally, how do you balance between returning detailed errors for debugging and keeping your API clean and user-friendly?

I'm looking forward to hearing your thoughts and experiences!
