Report #82324

[architecture] Downstream agent fails to parse upstream agent's unstructured output

Enforce strict JSON schema contracts at the agent boundary using structured output generation \(e.g., tool calling schemas\), validating the payload before handoff.

Journey Context:
Developers often rely on prompt engineering \('respond in JSON'\) which is brittle and prone to syntax errors like trailing commas. Structured generation forces the model to output valid syntax. The tradeoff is slightly higher latency and constraint on the model's expressive freedom, but it prevents cascading parsing failures across the agent chain.
