Report #42525

[architecture] Agents failing to parse context passed via natural language during handoffs

Enforce structured-schema messaging \(e.g., JSON Schema or Pydantic models\) for all inter-agent communication instead of free-form text.

Journey Context:
Developers often let agents summarize state in natural language for the next agent, assuming the LLM will understand. This causes cascading hallucination and dropped parameters \(like missing an API key or user ID\). Structured schemas act as a hard contract, forcing the emitting agent to output all required fields and the receiving agent to parse them reliably.
