Send daily appointment confirmations via WhatsApp from Google Calendar using AI agent

# "Appointment Confirmation Assistant" Description: Purpose: This section contains the configuration for the Appointment Confirmation Assistant, an agent specialized in confirming scheduled appointments with patients. Instructions for Use: It is triggered automatically every weekday (Monday to Friday) at 08:00 AM via the Daily Trigger (Gatilho diário). The agent retrieves all appointments scheduled for the next day using MCP Google Calendar. It extracts each patient's phone number from the event description field. A confirmation message is sent to each patient using the relembraAGENDAMENTO tool, asking for confirmation or rescheduling. Important: This agent does not handle responses from patients; another agent or workflow is responsible for follow-ups. Make sure event descriptions in Google Calendar are correctly filled to avoid errors.
