[counterintuitive] AI code review catches the same bug classes as human review, just faster

Deploy AI code review as a complement to human review, never a replacement. Use AI to catch: inconsistent error handling, missing null/edge-case checks, style and pattern deviations, known anti-patterns, and common vulnerability signatures. Reserve mandatory human review for: business logic correctness, temporal coupling between components, state machine transition errors, implicit contract violations, and any code where 'correct' depends on domain knowledge not present in the diff. Track which bug classes each catches to avoid coverage illusions.

Journey Context:
AI code review tools are sophisticated pattern matchers. They excel at finding bugs that manifest as deviations from common patterns: missing error handling, inconsistent null checks, known vulnerability signatures. But they systematically miss entire bug classes that humans catch: \(1\) Business logic errors—AI doesn't understand what the code SHOULD do, only what common patterns look like; \(2\) Temporal coupling—bugs where method A must be called before method B but nothing enforces this; \(3\) State machine violations—transitions that are syntactically valid but semantically wrong; \(4\) Implicit contract violations—breaking assumptions never written down. The OWASP code review guide categorizes these as requiring human review because they cannot be detected by pattern matching alone. The insidious danger: when AI catches many easy bugs, teams develop false confidence that coverage is comprehensive, and human reviewers start skimming—exactly the bug classes AI misses are the ones humans stop looking for.
