Shape the pace through the next reply
Read the reply, respond to one part and add a follow-up question. Ask for shorter answers or a different tone if that would help. When a reply misunderstands you, explain what you meant. If you start a fictional scene, make your role clear. Treat generated information as something to check before relying on it outside the conversation.
Try one opening
Choose one topic, give one sentence of context and ask one question. Then respond to the answer rather than writing a whole script in advance.
