Report #1567

[architecture] Agents failing to parse state updates from other agents due to free-form natural language messaging

Enforce structured schema \(e.g., JSON, Pydantic models\) for all inter-agent messages and state transfers. Reserve natural language only for the final user-facing output.

Journey Context:
LLMs are good at generating text but unreliable at extracting precise state from unstructured text. If Agent A tells Agent B 'I updated the user address to 123 Main St', Agent B might miss the address or format it wrong. Free-form messaging acts like a lossy compression algorithm for state. Structured schemas act as a strict contract, ensuring that state variables are unambiguously passed. This shifts the LLM's role from 'parser' to 'populator', drastically reducing hallucination in state synchronization.
