Code review for security and performance uses structured checklists to identify blocking vulnerabilities and bottlenecks. You apply these checklists after implementing features to assess reliability, security, and maintainability before merging pull requests.

When auditing distributed systems code for reliability, check idempotency, transaction boundaries, retry safety, and circuit breaker patterns. These specific considerations ensure your production system handles failures and network partitions without hidden defects.

Maintainability code review for production code uses reference guidelines to assess architectural decisions, testing coverage, and observability. Apply these checklists to existing code to uncover technical debt, ensure comprehensive documentation, and validate maintainability concerns.

This code review approach works for both new pull requests and auditing existing code. Apply the structured checklists after implementing features, before merging, or when assessing architectural decisions and testing coverage in current production systems.

The best way to structure code review feedback for blocking issues is using ready-to-use phrasing templates. These practical feedback templates categorize responses into blocking security vulnerabilities, important suggestions, and minor improvements for clear communication.

Code review misses hidden defects and technical debt in production systems when lacking a systematic approach. Using comprehensive checklists covering architecture, security, performance, and observability reveals issues that unstructured reviews overlook.
