Report #46786

[architecture] Unstructured text passed between agents causes parsing failures and hallucinated formats

Enforce strict JSON schema contracts at agent boundaries using structured output generation \(e.g., tool/function calling modes or constrained decoding\) rather than raw text prompting.

Journey Context:
Developers often treat multi-agent handoffs like human conversations, passing free-text. LLMs are notoriously bad at adhering to implicit formatting rules without constraints, leading to missing keys or broken syntax in the receiving agent. By forcing the generating agent to use structured output modes, the receiving agent is guaranteed a valid payload, eliminating an entire class of parsing exceptions and preventing the downstream agent from hallucinating context to fill missing fields.
