Report #43875

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

Enforce strict JSON Schema contracts at agent boundaries using structured output features \(e.g., tool/function calling or response\_format\) rather than relying on prompt-based formatting.

Journey Context:
Agents naturally output free text. Downstream agents fail if they expect a specific format, leading to fragile regex parsing or broken tool inputs. By enforcing a schema at the LLM API level, the contract is guaranteed by constrained decoding. Tradeoff: slightly higher latency and token usage for schema enforcement, and less flexibility in agent reasoning, but massive reduction in pipeline failures.
