Report #68207
[architecture] Unstructured text handoffs between agents cause parsing failures and hallucinated formats
Enforce strict JSON Schema contracts at agent boundaries using structured output generation \(e.g., tool/function calling or constrained decoding\) and validate programmatically before passing data to the next agent.
Journey Context:
Agents communicating via natural language often omit required fields or invent new formats, causing downstream agents to misinterpret or crash. Relying on prompt engineering alone to enforce format is fragile. By forcing a JSON Schema contract and validating it with code \(e.g., Pydantic\) at the boundary, you fail fast and can trigger targeted retries rather than letting garbage propagate through the chain.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
