Report #91610

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

Enforce strict JSON schema contracts \(e.g., Pydantic/Zod\) at the boundary between agents using structured outputs/function calling, rather than free-text generation.

Journey Context:
Unstructured text seems flexible but breaks down as context windows fill or agents misinterpret instructions. Function calling forces the LLM to output valid JSON conforming to a schema. Tradeoff: slightly higher token cost for tool definitions, but massive reduction in downstream parsing errors and strict contract enforcement.
