Report #75953

[architecture] Downstream agents receive malformed or logically flawed output from an upstream agent, causing them to hallucinate or crash

Insert a lightweight 'Verifier' agent or programmatic check between steps. The verifier compares the upstream output against the original task constraints and the inter-agent schema contract before routing.

Journey Context:
Trusting an LLM to perfectly follow the output format or logic is a recipe for cascading failures. A dedicated verifier \(either a cheaper/faster LLM or a deterministic rule engine\) acts as a gateway. The tradeoff is added latency and cost per step, but it dramatically reduces error propagation. Programmatic checks are preferred for syntax; LLM verifiers are reserved for semantic/logic checks where regex fails.
