Report #59117

[architecture] Downstream agent fails parsing because upstream agent returned malformed JSON or changed the data structure

Enforce strict JSON Schema validation at the inter-agent boundary. Treat every agent handoff as an API contract; reject and retry the upstream agent if the output doesn't conform.

Journey Context:
Relying purely on prompt instructions to enforce output structure is brittle. LLMs frequently omit keys or hallucinate types under stress. By validating against a JSON Schema before the receiving agent processes the payload, you catch structural errors early. The tradeoff is added latency from validation and potential retry loops, but it prevents cascading parsing failures deep in the pipeline.
