Report #77603

[architecture] Downstream agent fails parsing unstructured text from upstream agent

Enforce strict JSON schema contracts at the agent boundary using structured output features \(e.g., tool/function calling or structured outputs\) rather than relying on raw text parsing or regex extraction.

Journey Context:
Developers often let agents chat in natural language, assuming the LLM will adapt. However, as context windows fill or tasks get complex, formatting drifts and downstream agents fail with parsing errors. Structured outputs guarantee the contract, but add token overhead and restrict the agent's expressive freedom. The tradeoff is worth it for reliability in production pipelines.
