It sounds like you're experiencing inconsistent behavior with your call agent's appointment booking, where sometimes it correctly identifies booked times and other times it allows double-booking or marks booked times as available. From the information you've shared, your process uses tools like 'appGetAvailability' to check for open slots and 'apptBookAppointment' to reserve them, with integrations to webhooks and Google Calendar for event creation.
While the process steps and tools are clear, the specific reason for the inconsistency isn't detailed in the information provided. Issues like this can sometimes be related to how availability is checked or how quickly bookings are synced across systems, but without more details about the internal workings or error logs, it's hard to pinpoint the exact cause. If you have access to more detailed logs or error messages, reviewing those might help identify where the mismatch is happening.
