[counterintuitive] Should I have AI review code by reading it sequentially like a human reviewer?

Do not ask AI to 'review this code' like a human. Instead, decompose review into specific checks: 'Find race conditions in this concurrent code,' 'Check that all error paths release resources,' 'Verify authorization checks on all endpoints.' Targeted prompts catch 3-5x more real bugs than open-ended review requests.

Journey Context:
The default approach to AI code review is pasting a diff and asking 'review this code,' mirroring how humans review. This is suboptimal for AI. Humans do holistic review because we simultaneously reason about style, correctness, security, and design. AI performs much better with targeted, specific instructions because: it reduces the task to pattern matching \(which AI is good at\) rather than judgment \(which AI is bad at\); it prevents the model from spending capacity on low-value observations like style nits and forces focus on the requested dimension; it makes output verifiable—you can check whether AI found race conditions specifically, rather than getting vague 'looks good but consider renaming this variable.' The counterintuitive insight: asking AI to do less \(one specific check\) produces more valuable output than asking it to do more \(comprehensive review\). AI's capacity per inference is finite, and broad requests dilute that capacity across many dimensions, producing shallow analysis on each.
