[architecture] Agents failing to parse arguments passed via natural language handoffs

Use structured schema messaging \(JSON\) for inter-agent communication, not free-form natural language. Define strict input/output schemas for agent handoffs just like you would for tool calls.

Journey Context:
It is tempting to let agents 'talk' to each other via natural language since they are LLMs. However, free-form handoffs cause silent data loss, hallucinated parameters, and parsing failures. The receiving agent might miss a crucial ID or misinterpret a constraint. By enforcing JSON schemas \(or function-calling formats\) for agent-to-agent transitions, you force the sending agent to serialize the exact required state, making the contract unambiguous and machine-parseable, reducing error rates drastically.
