Report #31048

[architecture] Unstructured text passed between agents causes cascading parsing failures and hallucinated tool calls

Enforce strict JSON Schema validation at the boundary of every agent handoff; reject the output and force a retry if the schema fails.

Journey Context:
Developers often treat multi-agent handoffs like human chats, passing free-text 'thoughts'. LLMs are bad at extracting parameters from free text, leading to missing arguments or hallucinated tool calls in the receiving agent. By forcing the output into a strict JSON schema, the contract becomes machine-verifiable. The tradeoff is slightly higher latency and occasional invalid generation retries, but it guarantees the downstream agent receives exactly what its tools expect.
