Report #29901
[architecture] Unstructured text passing between agents causes hallucinated parsing and cascading failures
Enforce strict JSON Schema contracts at agent boundaries; treat inter-agent communication as an API, not a conversation. Validate outputs against the schema before routing to the next agent, and force a retry with error feedback on validation failure.
Journey Context:
Developers often treat multi-agent handoffs as chat messages, assuming the receiving agent will 'figure it out.' This leads to fragile chains where a missing field or slight phrasing change crashes the downstream agent. By enforcing a strict schema \(like an OpenAPI spec for microservices\), you decouple the agents. If Agent A fails to produce valid JSON, it is caught immediately, preventing Agent B from hallucinating the missing data. The tradeoff is higher prompt complexity and token usage for Agent A to conform, but it guarantees structural integrity across the pipeline.
