Report #75544

[architecture] Cascading parsing failures from free-form natural language communication between agents

Use structured schemas \(JSON schema, Pydantic models, or function calls\) for all inter-agent messaging and handoffs instead of unstructured text.

Journey Context:
While natural language seems flexible, LLMs hallucinate or omit required parameters when generating free-text messages for other LLMs, causing the receiving agent to fail deterministically. Structured outputs force the sending agent to produce machine-parseable state, making handoffs reliable and eliminating the need for a receiving agent to 'extract' data from prose.
