Report #85213

[architecture] Cascading parse failures when passing unstructured text between agents

Enforce strict JSON schema contracts at agent boundaries using structured output generation \(e.g., tool calls or response\_format\), and validate against the schema before the receiving agent processes the payload.

Journey Context:
Developers often let agents communicate via natural language, assuming the receiving LLM can handle ambiguity. However, slight variations in formatting \(e.g., missing a key field\) cause downstream agents to hallucinate or crash. Structured output forces the emitting agent to serialize its state, acting as a hard type-check. The tradeoff is slightly higher token cost and generation latency, but it eliminates an entire class of state-propagation bugs. Alternatives like 'prompting harder' are brittle and fail silently.
