[architecture] Agents hallucinating parameters when passing tasks via free-form natural language

Use structured JSON schemas for inter-agent messaging, treating agent handoffs as strict API contracts rather than conversational prompts.

Journey Context:
LLMs are great at natural language, but when Agent A passes context to Agent B, free-form text leads to dropped constraints or hallucinated arguments. JSON schemas enforce exact parameter passing. Tradeoff: slightly more rigid and requires schema definition upfront, but eliminates parsing failures and ensures B receives exactly the state it needs to act.
