Report #89904

[architecture] Unstructured text passed between agents causes parsing failures and hallucinated parameters in downstream agents

Enforce strict JSON Schema contracts at agent boundaries; reject the message and force a retry on the upstream agent if validation fails

Journey Context:
Developers often let agents chat in natural language for flexibility. However, downstream agents fail silently or hallucinate missing fields when parsing free-text. By enforcing a strict schema, you shift the burden of correctness to the generating agent's function calling or structured output capability, making the boundary deterministic. Tradeoff: slightly higher rejection/retry rate and token usage, but eliminates whole classes of parsing bugs and cascading errors.
