Report #41435

[architecture] Unstructured text between agents causes cascading parsing failures

Enforce strict JSON Schema contracts at agent boundaries using structured outputs \(e.g., OpenAI function calling / tool schemas\), treating the schema as an API contract between microservices.

Journey Context:
Developers often let agents chat in natural language because LLMs are good at it. However, slight variations in formatting break the parser of the receiving agent. By enforcing a JSON schema, the receiving agent's input parser fails fast on contract violations rather than hallucinating interpretations of malformed text. The tradeoff is slightly higher token cost and latency for schema enforcement, but it eliminates an entire class of state-parsing bugs.
