Calendar Setup - Enable Fast Queries

**Purpose:** Grant 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
• Do not promise that a Mac permission dialog will appear. When Dex runs inside VS Code or Cursor, that dialog often never shows.

2. **If Already Authorized:**

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

3. **If NotDetermined or Denied:**

• VS Code and Cursor are first-class Calendar surfaces. Send the person to System Settings for the app Dex is running in. Do not send them to a standalone terminal as the only path. Do not tell them to wait for a popup. Do not tell them that granting Terminal, Python, or python3 is enough.
• Show clear instructions:

     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 the app Dex is running in — VS Code or Cursor — and turn it on
     5. Click that app and set access to Full (not "Add Only")
     6. Quit the editor and open it again
     7. Run /calendar-setup again to verify

• A Terminal grant does not transfer to the editor. Reinstalling Dex does not fix a missing editor grant.

4. **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

5. **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 for that app

Technical Notes

• **EventKit vs AppleScript:** EventKit uses database queries (fast), AppleScript loads all events then filters (slow)
• **Permission is per app:** macOS grants Calendar access to the app that is asking. When Dex runs inside VS Code or Cursor, grant that editor. A Terminal grant does not carry over.
• **Permission is persistent:** Once granted to the editor, access lasts until it is 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

**No permission popup / access still denied:**

• Do not wait for a dialog, and do not switch to Terminal as the only fix
• Open System Settings → Privacy & Security → Calendars
• Turn on VS Code or Cursor (the app Dex is running in) and set Full access
• A grant already given to Terminal, Python, or python3 does not transfer
• Reinstalling Dex does not fix this

**Still seeing slow queries after granting access:**

• Restart the app Dex is running in (VS Code or Cursor) to reload the calendar connection
• Verify permission: `python3 core/mcp/scripts/check_calendar_permission.py`
