Report #74700

[architecture] Unstructured text passing between agents causes cascading parsing failures and hallucinations

Enforce inter-agent communication strictly through structured tool-call schemas \(JSON Schema\) rather than free-text parsing. The orchestrator should treat agent outputs as API payloads.

Journey Context:
Developers often let agents chat in natural language, assuming the LLM will figure it out. However, minor formatting deviations break downstream agents. By forcing the output through a strict function-calling schema \(Structured Outputs\), you shift the contract from 'hope the LLM formats it' to a deterministic API boundary. The tradeoff is slightly higher token cost for schema enforcement, but it eliminates an entire class of parsing bugs and context drift.
