[architecture] Agents failing to parse context or dropping parameters when passing free-form natural language messages

Use structured JSON schemas for all inter-agent communication and handoffs, enforcing strict contracts for required parameters.

Journey Context:
Passing natural language between agents seems flexible but introduces ambiguity. The receiving agent must parse unstructured text, often hallucinating or dropping critical variables \(like user IDs or session state\). Structured schemas act as an API contract between agents, ensuring no state is lost in translation and reducing token waste on descriptive filler.
