Report #82785

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

Enforce strict JSON Schema contracts at agent boundaries using structured output generation \(e.g., tool/function calling formats\), and reject/terminate the workflow if validation fails rather than attempting auto-repair by the same agent.

Journey Context:
Developers often let agents chat in natural language for flexibility. However, LLMs are unreliable parsers of free-text. A minor formatting deviation by Agent A causes Agent B to hallucinate missing fields. Alternatives like 'ask Agent A to fix it' create infinite retry loops. Enforcing a strict schema at the boundary \(like an API contract\) decouples the agents, makes failures deterministic, and allows the orchestrator to handle exceptions gracefully.
