[architecture] Passing an agent's output directly to the next agent without verifying it satisfies the original goal leads to off-topic drift

Insert a lightweight Verifier agent \(LLM-as-a-judge\) between the worker agent and the next step. The Verifier compares the worker's output against the original task prompt and a rubric, passing it on only if it passes, or routing back for revision.

Journey Context:
A single agent might misinterpret a prompt and go off-track. The next agent, just following orders, continues the drift. A Verifier agent acts as a gatekeeper. The tradeoff is added latency and cost \(an extra LLM call per step\). Alternatives like simple keyword matching are too brittle. LLM-as-a-judge is the only flexible enough heuristic for unstructured tasks, provided the verification rubric is strictly defined.
