Best Practices Summary

• Always wrap errors when crossing package boundaries
• Include operation context (“unmarshal”, “dial”, “fetch”)
• Include relevant identifiers (userID, filename, URL)
• Don’t include sensitive data (passwords, tokens, secrets)
• Be consistent within your codebase
• Consider your audience (internal vs external errors)
• Use structured logging for detailed debugging info instead of cramming everything into error messages
