📄 Description

Overview

I was trying out the complete working example of the personal assistant tutorial and with the current system prompt, the calendar scheduling agent would always schedule an event, even if get_available_time_slots would not return a matching time slot. For example when I change the code of get_available_time_slots to something like this:

@tool
def get_available_time_slots(
    attendees: list[str],
    date: str,  # ISO format: "2024-01-15"
    duration_minutes: int
) -> list[str]:
    """Check calendar availability for given attendees on a specific date."""
    return []

Although this is just a tutorial of course, I think the sub agent should be smart enough to not schedule an event if there is no available time slot. This PR corrects the system prompt of the agent so that events are not scheduled, in the case where there is no suitable time slot.

I also changed the model of the complete example from claude-haiku-4-5-20251001 to gpt-4.1 since I never got the agent to work with the Anthropic model.

Note that I have tested the python code but could not test the typescript example.
