Option B removes the prompt-level suppression responsible for the false negatives while preserving machine-readable metadata. Anthropic’s current code-review prompting guidance warns that instructions such as “only report high-severity issues” or “be conservative” may be followed literally: Claude can identify genuine defects during analysis but omit them from its output. Anthropic recommends requesting all findings and applying filtering separately.

Confidence and severity fields allow downstream code to apply adjustable thresholds without forcing the model to discard evidence during generation. A schema can require fields such as file, line, description, severity, confidence, evidence, and recommended action; Anthropic’s Structured Outputs documentation supports enforcing such a response contract. Option A repeats the same suppressive instruction and is likely to reproduce the same omissions. Option C removes the explicit reporting structure and leaves filtering behavior undefined. Option D may improve analysis depth, but extended reasoning does not override a direct instruction to suppress uncertain findings. Separating detection from deterministic filtering preserves recall, structure, and operational control.
