Code Review Best Practices: How to Give and Receive Feedback That Actually Improves Code

Short summary

Code review is the highest-leverage practice for shipping reliable software—catching bugs before production and spreading team knowledge. Structure reviews by priority (correctness/security → design → style), use prefixes to clarify intent, and batch reviews in focused blocks to catch 40% more defects. Keep PRs under 400 lines, provide specific constructive feedback, and self-review your code first.

• •Structure reviews by priority: correctness/security first, then design, then style
• •Use prefixes (blocking, suggestion, nit, question) to distinguish issue severity and reduce friction
• •Batch reviews and keep PRs small for 40% better defect detection
