Report #62217

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

Enforce strict schema contracts \(e.g., JSON Schema, Pydantic\) at agent boundaries. Use function calling or structured output to guarantee the receiving agent gets a machine-validatable payload, not free-text.

Journey Context:
Developers often treat LLMs like human colleagues, passing free-text messages. But downstream LLMs easily misinterpret text or hallucinate missing fields. By enforcing a schema contract, you shift validation from 'semantic interpretation' to 'syntactic validation'. If the upstream agent fails the schema, you retry or escalate before the downstream agent ever runs. The tradeoff is slightly higher latency/token cost for structured generation, but it eliminates an entire class of cascading format errors.
