Calendar Setup - Enable Fast Queries

Purpose: Grant Python calendar access for 30x faster calendar queries (30s → <1s)

When to run:

• After initial Dex installation
• If calendar queries feel slow
• If you see "Calendar access denied" errors

Process

1. Check current permission status:

   • Run the permission checker: python3 core/mcp/scripts/check_calendar_permission.py
   • Show the user what status was returned

2. If Already Authorized:

   • Great! Calendar queries are already optimized.
   • No action needed.

3. If NotDetermined (permission not yet requested):

   • The script will show a macOS permission dialog
   • Guide user: "Click 'OK' when the dialog appears to grant Python access to Calendar"
   • Run the script again to verify

4. If Denied (previously rejected):

   • Show clear instructions:
     Copy

     To enable fast calendar queries:
     
     1. Open System Settings (Command+Space, type "System Settings")
     2. Click "Privacy & Security" in the sidebar
     3. Click "Calendars"
     4. Find "Python" or "python3" in the list
     5. Enable the checkbox
     6. Run `/calendar-setup` again to verify
     

5. If Restricted:

   • Explain: "Calendar access is blocked by system policies (parental controls or enterprise MDM)"
   • Calendar queries will use AppleScript (slower but functional)
   • No user action possible

6. After Success:

   • Confirm: "✅ Calendar access granted! Queries are now 30x faster."
   • Explain: "Calendar queries now use native EventKit instead of AppleScript"
   • No need to run this again - permission is persistent

Technical Notes

• EventKit vs AppleScript: EventKit uses database queries (fast), AppleScript loads all events then filters (slow)
• Permission is persistent: Once granted, Python keeps access until explicitly revoked
• Privacy: All calendar data stays local - Dex never sends calendar data anywhere
• Fallback: If EventKit isn't available, Dex falls back to AppleScript (works but slower)

Troubleshooting

"Module EventKit not found":

• Run: pip3 install pyobjc-framework-EventKit
• This should have been installed during Dex setup

Permission dialog doesn't appear:

• System Settings might already show "Denied" from a previous attempt
• Follow the manual steps above to toggle permission on

Still seeing slow queries after granting access:

• Restart your coding harness (Cursor/Claude Code/Pi) to reload MCP server
• Verify permission: python3 core/mcp/scripts/check_calendar_permission.py
