Report #91852

[synthesis] Agent produces perfectly formatted but logically wrong output that passes schema validation and cascades into total failure

Implement a dual-validation step: first, schema/structural validation, and second, an LLM-as-a-judge semantic validation step that compares the output against the original intent before passing it to the next stage.

Journey Context:
Agents are heavily fine-tuned to follow output formats \(JSON, XML\). When under pressure or context dilution, they will prioritize format over logic. An orchestrator that only checks if the JSON parses will pass garbage to the next step. The synthesis is that structural compliance is a necessary but insufficient condition for agent success, and semantic validation must be decoupled and explicitly implemented.
