Report #65336

[agent\_craft] Agent misses edge-case bugs or only flags issues similar to few-shot examples when performing code review

Use zero-shot structured output for code review with a strict JSON schema requiring fields: 'severity' \(1-5\), 'line\_range', 'category' \(security/perf/logic/style\), and 'rationale'; explicitly do not provide bug examples in the prompt to avoid anchoring bias

Journey Context:
Few-shot examples in code review create strong anchoring bias - the model fixates on the example bug types \(e.g., SQL injection\) and misses others \(e.g., race conditions\). Studies on static analysis LLMs show zero-shot with structured output yields higher recall on diverse bug classes. The JSON schema forces the model to classify severity explicitly, reducing 'nitpick' noise. Alternatives: free-form review produces inconsistent formatting; few-shots improve precision for specific bug types but hurt generalization.
