Claude Prompts for Code Review in Engineering

Run a code review at the level of a senior engineer who has been burned: hidden state, error paths, performance cliffs, security, and the change's effect on the surrounding system.

Analyze a function, endpoint, or system component for performance bottlenecks — identifying N+1 queries, unnecessary computation, memory leaks, and algorithmic inefficiencies with specific fixes and benchmarking guidance.

Conduct a thorough pull request review covering correctness, security, performance, test coverage, and code quality — with prioritized, actionable feedback for each finding.

Transform raw code review observations into polished, professional feedback — clearly communicating the issue, the reasoning, and the suggested fix without being discouraging or vague.

Systematically assess a feature or code change for security vulnerabilities — covering OWASP Top 10, authentication, authorization, data exposure, and input handling — with severity ratings and concrete fixes.
