Report #6041

[architecture] Agents passing unstructured natural language to each other and hallucinating parameters or failing to parse instructions

Enforce strict JSON schema for all inter-agent handoffs and control-plane messages. Natural language should only exist inside specific data payloads, never as the routing or instruction mechanism.

Journey Context:
LLMs naturally want to chat, but free-form text between agents leads to cascading parsing errors and infinite loops of 'I didn't understand, please provide the JSON'. Structured schemas make the handoff deterministic and machine-readable. The tradeoff is slightly higher token usage for schema enforcement, but it prevents the fragility of regex-parsing chat responses.
