Report #96698

[architecture] Cascading parse failures when Agent B receives unexpected JSON structure from Agent A

Enforce strict structural contracts \(e.g., JSON Schema, Pydantic\) at the agent boundary using structured outputs, and reject non-conforming payloads before executing Agent B's logic.

Journey Context:
Prompting Agent A to 'return JSON' is fragile; LLMs frequently omit keys or change types. If Agent B expects result.data but gets result.output, it crashes or hallucinates. Strict validation at the boundary allows Agent A to self-correct \(via retry\) or triggers a deterministic fallback before Agent B even runs, preventing cascading multi-agent failures.
