A hospital agent's topics use one-word triggers, so a question that should miss still enters a topic. Questions that truly match nothing still need an honest miss path. What should the architect change?
Select an answer to reveal the explanation.
Short Explanation
A one-word trigger is a wide net, and it catches questions you meant to let pass. You replace those triggers with phrases that mean the intent, or you adjust the orchestration, and you keep a fallback for a true miss. Deleting the fallback does not make the net any narrower.
Full Explanation
A one-word trigger matches too broadly, so a question that should miss still enters a topic. The architect replaces those triggers with phrases that mean the intent, or adjusts orchestration so only a real request reaches a topic. A fallback remains for a question that truly matches nothing, because that miss path is still required. Deleting the fallback topic turns those true misses into silence and does not stop a one-word trigger from claiming a question it should have left alone. Shortening every trigger to a single letter makes the match even wider, so more questions enter a topic by accident. Making the fallback message the clinical answer sends unmatched questions, including nonsense, down a path that pretends to be care. The fallback stays honest: it covers a miss, and it does not become the answer for questions a topic should have claimed. Exam caveat: a topic that fires on one word is a matching problem, and removing the fallback does not repair that match. Operational check: ask a question that should miss and confirm it no longer enters a topic, then ask nonsense and confirm the fallback is what still answers.
