Report #88904

[architecture] Unstructured prompt-based contracts between agents lead to hallucinated keys and broken handoffs

Enforce strict JSON Schema validation at the orchestration layer for all inter-agent messages, using structured output generation \(e.g., function calling\) rather than relying on prompt instructions.

Journey Context:
Developers often ask Agent A to 'respond in JSON with keys X, Y' and pass it to Agent B. Under complexity, A drops keys or hallucinates new ones, causing B to crash or hallucinate further. Treating the agent boundary like a network API with a strict schema acts as a compiler, failing fast at the boundary rather than propagating garbage state downstream.
