Report #52705

[architecture] Passing agent outputs directly to the next agent based solely on schema validation, missing semantic errors

Implement a two-tier validation gate between agents: 1\) Structural \(JSON Schema\) to verify keys/types, and 2\) Semantic \(LLM-as-a-judge or deterministic rules\) to verify business logic and value constraints.

Journey Context:
JSON schema validation ensures the keys exist, but not that the values make sense \(e.g., \{'action': 'refund', 'amount': -500\}\). A semantic validation step, either via a lightweight LLM evaluator or deterministic business rules, acts as a true trust boundary. Tradeoff: Adds latency and cost to the pipeline, but prevents cascading semantic drift where one bad value corrupts downstream reasoning.
