Report #1619

[architecture] Agents failing to parse or ignoring instructions from other agents in free-form natural language

Enforce structured-schema messaging \(e.g., JSON Schema, Pydantic models, or strict tool-call returns\) for all inter-agent communication. Reserve natural language only for the final user-facing output.

Journey Context:
It is tempting to let agents 'chat' via natural language since they are LLMs. In practice, free-form inter-agent chat leads to hallucinated instructions, ignored constraints, and parsing failures. By forcing communication through structured schemas or tool invocations, the receiving agent is constrained to process machine-readable data, eliminating ambiguity and making the coordination protocol deterministic and debuggable.
