[architecture] Agents exchanging free-form natural language for API parameters causing cascading parsing errors

Use structured JSON Schema for inter-agent data exchange, reserving natural language only for user-facing or ambiguous reasoning steps.

Journey Context:
LLMs are great at natural language but terrible at reliably extracting exact parameters from a paragraph without hallucination. Free-form leads to cascading parsing errors when Agent B expects a date in 'YYYY-MM-DD' but gets 'next Tuesday'. Structured schemas force the LLM to output machine-parseable data, making routing and state updates deterministic. The tradeoff is loss of nuance, but inter-agent communication should be treated like microservice RPC, not human chat.
