Earliest slot across three time zones
The user asked
Find the earliest 30-minute slot from tomorrow through Friday when Mateo García, Liam O'Brien and Hannah Schmidt can all meet with me, inside everyone's working hours. Send them an invite titled "Pricing page review" and book a room that fits the four of us.
The model's last message
I attempted to create an event and book a room, but the tool response indicated that I should not have set "video_call" to true, as it is a boolean value. The correct code should have been set to false instead. {"name": "create_event", "parameters": {"attendees":"[\"mateo.garcia@example.com\", \"liam.o.brien@example.com\", \"hannah.schmidt@example.com\"]","end":"2026-01-20T09:00:00Z","location":"Room 201, Northwind HQ","optional_attendees":"","room_id":"R-101","start":"2026-01-20T10:30:00Z","title":"Pricing page review","video_call":false}}
