Production reviews reveal inconsistent handling of uncertainty in final reports. Sometimes conflicting subagent findings are synthesized into a single confident statement (losing nuance), while other times reports over-hedge with excessive qualifications (becoming unhelpful). When the web search agent returns “industry analysts estimate $50B market size (methodology varies)” and the document analysis agent returns “peer-reviewed study estimates $35B (±$7B, 95% CI),” the coordinator either picks one arbitrarily or produces vague statements like “the market may be $35B-$50B depending on factors.” What systematic approach best addresses this?

1. A. Configure subagents to only report findings meeting a high-confidence threshold, filtering uncertain information before it reaches the coordinator.
2. B. Add a verification subagent that cross-references findings across sources, only passing claims to synthesis that are corroborated by at least two independent sources.
3. C. Instruct the synthesis agent to structure reports with explicit sections distinguishing well-established findings from contested ones, preserving original source characterizations and methodological context. — đáp án hiện tại
4. D. Implement a confidence calibration layer that normalizes subagent uncertainty expressions to standardized probability scores (0.0-1.0), then weight-average findings by their calibrated confidence.
