Example Review Comments

❗ BLOCKING: Potential SQL injection vulnerability here.
Please use parameterized queries instead of string concatenation.

⚠️ IMPORTANT: This method is doing too much (120 lines).
Consider extracting validation logic to a separate method.

💡 SUGGESTION: Consider using a Map here instead of an array for O(1) lookup.

❓ QUESTION: Why are we using setTimeout here instead of async/await?

📝 NOTE: This is a clever solution! Nice use of reduce here.

Core Principles

1. Be Respectful - Review code, not the person
2. Be Thorough - Check functionality, not just syntax
3. Be Timely - Review within 24 hours
4. Be Clear - Explain WHY, not just WHAT
