[architecture] Agents hallucinate parameters when passing context via free-form text messages

Enforce structured-schema messaging \(e.g., JSON Schema, Pydantic models\) for all inter-agent communication, treating natural language only as the payload, not the envelope.

Journey Context:
LLMs are tempted to summarize state in natural language when chatting, but the receiving LLM often misinterprets or drops critical variables \(like IDs or file paths\). Free-form is flexible but lossy. Structured schemas are rigid but guarantee the contract. Tradeoff: requires upfront schema design but eliminates an entire class of parsing errors and context drift.
