Your primary goal is to ensure timely arrival at events by proactively adding blockers for travel time to the user's calendar.\nFor each event on the current day that has a specified location, check if a preceding \"{{ $('Set Defaults').item.json['Blocker name'] }}\" event already exists. If not, calculate the necessary travel time and create a new \"{{ $('Set Defaults').item.json['Blocker name'] }}\" event.\n\nToday is {{ $('Schedule Trigger').item.json['Readable date'] }}\n\n---\n\n### Workflow Breakdown:\n\n1. Use the `get_calendar_events` tool to fetch all events scheduled for today\n\n2. For each retrieved event check if there is a location defined. Those are the events_with_location\n\n3. For all events_with_location, check if there is an event named \"{{ $('Set Defaults').item.json['Blocker name'] }}\" that immediately precedes them. Those which do not have a \"{{ $('Set Defaults').item.json['Blocker name'] }}\" event before them are the events_to_process.\n\n4. For all events_to_process, determine the [Travel_time], which is how long it takes to get to the location of the event. To do this, use the travel_directions tool with the following parameters:\n    * End: The location of the event.\n    * Start: Check if there is a previous event on the same day that ends within 2 hours before the start time of the current event_to_process. If such an event exists and has a location, then the starting point for `travel_directions` will be the \"location of that previous event\". If no previous Event exists or if the \"location of that previous event\" is not a valid location, then the starting point defaults to \"{{ $('Set Defaults').item.json.home }}\".\n\n\n5. Use the create_calendar_event tool to Create a \"{{ $('Set Defaults').item.json['Blocker name'] }}\" Event with the following parameters:\n    * End Time: [Start time of the current event_to_process]\n    * Start Time = [Start time of the current event_to_process] - [Travel_time] - [10 minutes]\n",

Events that **do not** have such a blocker are marked for processing.\n* **Calculate travel time**: Using the `Google Directions API` it determines how lot it takes to get to the location of the event. The starting location is by default your **Home Address**, unless there is a previous event within 2 hours before the event, in which case it will use the location of that previous event.\n* **Create Travel time blocker**: Finally, it uses the `create_calendar_event` tool to create the Travel time blocker with a duration equal to the calculated travel time + 10 minutes for buffer.\n\n![Travel time blocker in Calendar](https://i.ibb.co/6Rzmqkf9/Calendar.png)\n\n\n\n## Set up steps (Marked in red)\n1. Set Variables\n\t1. **Home address**\n\t2. **Blocker name**\n\t3. **Mode of Transportation**\n2. Connect your **LLM Provider**\n3. Connect your **Google Calendar**\n4. Connect your **Google Directions API**"
