Report #69307

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

Enforce strict JSON Schema contracts at agent boundaries using structured output generation, rejecting any payload that fails validation before routing to the next agent.

Journey Context:
Developers often treat multi-agent handoffs like human conversations—passing free-text. This breaks because LLMs are unreliable at extracting implicit structure, leading to missing arguments or hallucinated formats in downstream agents. Alternatives like regex parsing are brittle. JSON Schema acts as a compiler-level contract: if the output fails validation, the orchestrator forces a retry or routes to an error handler, guaranteeing the downstream agent receives a well-typed payload.
