[counterintuitive] AI code review catches subtle logic bugs better than humans

Use AI code review exclusively for style, missing error handling, and standard pattern deviations. Rely on humans for logic bugs and intent-mismatches. Prompt AI to check 'does this code follow standard error handling for this API' rather than 'is this logic correct'.

Journey Context:
The belief is that AI's vast pattern-matching allows it to spot subtle bugs. In reality, AI assumes the code's intent is correct and hallucinates plausible execution paths. It misses entire bug classes where the code does exactly what the author wrote, but what they wrote doesn't match what they meant. Humans are superior at reading intent. AI is genuinely better at catching missing standard patterns \(e.g., 'you forgot to close this resource'\) because it has seen millions of examples of the correct pattern.
