Report #82993

[architecture] Unstructured text handoffs cause parsing failures between agents

Enforce strict JSON schema contracts at agent boundaries using structured outputs, treating the schema as an internal API interface.

Journey Context:
Developers often pass raw string outputs between agents, assuming the downstream agent will 'just understand.' This breaks when LLM verbosity or formatting changes. By enforcing a strict JSON schema \(acting as an internal API contract\), the orchestrator can programmatically validate the output before routing, catching format drift immediately. The tradeoff is slightly higher token usage and latency for schema enforcement, but it prevents cascading parsing errors in multi-step pipelines.
