Report #23174

[architecture] Cascading parse failures when agents pass unstructured text

Enforce strict structured output \(JSON schema\) at agent boundaries using constrained decoding, treating the schema as an immutable inter-agent contract.

Journey Context:
Developers often let agents chat freely, assuming the downstream LLM will just figure out the format. However, a minor format deviation by Agent 1 causes Agent 2 to hallucinate or crash. By forcing Agent 1 to output via a strict schema \(e.g., function calling\), you decouple generation from parsing. Tradeoff: slightly higher latency and token usage for schema enforcement, but massive gains in pipeline stability and debuggability.
