Report #38787

[frontier] Agents hallucinating confidence in multi-step tool chains

Enforce structured reflection schemas that require the model to output calibrated confidence scores and uncertainty flags before executing tools.

Journey Context:
Naive chain-of-thought exposes raw reasoning that downstream systems cannot parse for reliability. Structured outputs with mandatory 'confidence: 0.0-1.0' and 'uncertainty\_type' fields force explicit calibration. This enables early termination chains when confidence drops below thresholds, preventing error propagation. Alternatives like log-probability thresholds are model-specific and opaque; structured reflection is portable across providers.
