Report #21144

[architecture] Unstructured text passing between agents causes cascading parsing failures

Enforce strict schema contracts \(e.g., JSON Schema\) at the agent boundary; reject and retry if validation fails.

Journey Context:
Developers often treat LLM outputs as reliable strings to be passed directly. But LLMs hallucinate formats. Without a strict contract, Agent B gets garbage and hallucinates further. Using structured output enforcement at the boundary ensures Agent B receives a valid payload. Tradeoff: strict schemas can cause high rejection rates if the prompt isn't tuned for the schema, but a retry loop is cheaper than a cascading multi-agent failure.
