sudo sqlite3 ~/Library/Application\ Support/com.apple.TCC/TCC.db \

Configure in ~/.hermes/config.yaml:

    default_calendar: "Work"        # Default calendar name
    default_duration_minutes: 60    # Default meeting duration
    default_alert_minutes: 15       # Default reminder before event
    working_hours:
      start: "09:00"
      end: "17:00"
      timezone: "America/Phoenix"
      days: [1, 2, 3, 4, 5]        # Mon-Fri

The skill uses CalDAV (the standard calendar protocol) to communicate with macOS Calendar. This provides a uniform interface regardless of which backend you use (iCloud, Exchange, Google).

CorpusIQ Use Cases

  1. Content Calendar Management: Schedule social posts, blog publications, and video releases directly from Hermes. "Schedule the UGC video #47 for Thursday at 6pm"

  2. Meeting Coordination: Hermes can find mutually available slots for team meetings across multiple calendars.

  3. Deadline Tracking: Set reminders for product milestones, launch dates, and customer deliverables. "Set a reminder for 'CorpusIQ v2 launch' on August 1st with 1-week and 1-day alerts"

  4. Daily Standup Automation: Automatically schedule daily standups that respect working hours and existing commitments.

  5. Client Follow-up Calendar: Create calendar events for follow-up tasks based on email conversations.

Limitations

  • macOS Only: This skill uses CalDAV via macOS - not available on Linux or Windows.
  • Calendar Permissions: macOS privacy settings may require manual approval on first use.
  • Read-Only External: Some shared calendars may be read-only depending on permissions.

Troubleshooting

Symptom Likely Cause Fix
"Calendar access denied" macOS privacy permissions Grant access in System Settings → Privacy → Calendars
"Calendar not found" Calendar name mismatch List calendars: hermes calendar list
Events not syncing CalDAV sync delay Wait 30-60 seconds; check internet connection
"Invalid recurrence rule" Complex custom rule syntax Use simple recurrence patterns (daily/weekly/monthly)
Working hours not respected Timezone mismatch in config Verify timezone matches systemsetup -gettimezone
