Give the agent all details before it books lunch
A usability researcher gave ChatGPT's agent mode a short, deliberately incomplete prompt about a business lunch on Friday at noon. The agent asked no clarifying questions, spent six minutes on ten searches and 96 sources, and suggested three restaurants without menu or price. The reservation went through, but was time consuming and prone to misunderstandings when he added a shellfish allergy. August 2025, one task.

Try it with ChatGPT
Find a restaurant for [occasion] for [number] people on [day and time] near [place]. Before you search: ask me about atmosphere, budget, allergies and what matters most. Show me three suggestions with menu, price level and open times. Do not reserve before I have chosen, and do not pay anything. You are done when I have three suggestions to choose from, or have said which one you should reserve.
