Report #61964

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

Enforce strict JSON schema contracts at the boundary of every agent handoff, validating the payload before execution of the next agent.

Journey Context:
LLMs default to chatty text. If Agent B expects a specific list of IDs, Agent A's conversational wrapper breaks Agent B. Structured output solves this, but you still need runtime validation at the contract boundary because LLMs hallucinate keys or omit required fields. Tradeoff: strict schemas reduce agent flexibility but guarantee pipeline stability.
