A Quarkus walkthrough routes requests and checks specialist replies through a shared Jev/Laya interface.

Before you dive in

What you’ll find in the original

  1. A Planner can use typed Choice answers to select one specialist agent.
  2. An OutputGuardrail can separately reject replies that fail bounded checks.
  3. The author could not access Jev, so Jev runs used a deterministic stub while only Laya ran for real.
Worth knowing

Do not interpret the article’s Jev path as a live Jev evaluation; the author explicitly used a stub.
