Report #66649

[architecture] Inter-agent context loss and hallucinated parameters from free-form text handoffs

Enforce structured JSON schema \(or Pydantic/TypedDict\) for all inter-agent messages and handoff payloads, strictly avoiding unstructured natural language summaries for state transfer.

Journey Context:
Developers often use natural language for agent-to-agent communication because LLMs excel at generating it. However, downstream LLMs frequently hallucinate or omit critical details when parsing unstructured text into actionable parameters. Structured schemas act as a strict contract, ensuring state variables \(like file paths, error codes, or user IDs\) survive handoffs without degradation. The tradeoff is slightly higher prompt token overhead for schema definitions, but the elimination of cascading parsing errors makes it strictly superior for reliable coordination.
