Report #41207

[architecture] Unstructured text handoffs between agents cause cascading parsing failures

Enforce strict JSON Schema contracts at agent boundaries using structured output features \(e.g., tool/function calling\) and validate payloads deterministically with a library like Pydantic before allowing the next agent to process the input.

Journey Context:
Developers often pass free-text strings between agents because LLMs generate text naturally. However, the receiving agent's prompt parser easily breaks if the text format deviates slightly, leading to infinite retry loops or hallucinated tool calls. By enforcing a strict JSON schema at the boundary, the output becomes machine-parseable, and validation failures can be caught deterministically before the next agent executes side effects, shifting trust from probabilistic generation to deterministic validation.
