Calendar & Scheduling Assistant

Review your schedule, find meeting slots, and create events with smart suggestions.

When to Use

Use this skill when:

• User asks "what's on my calendar" or "what meetings do I have today"
• User wants to "schedule a meeting" or "find time to meet"
• User mentions "check my availability"
• User says "when am I free this week"
• User wants to create a calendar event

Important: This skill NEVER creates or modifies events without explicit user confirmation.

Dynamic Context

The following live data is available:

Today's agenda:

!`gog calendar events --today --json 2>/dev/null || echo "GOG_NOT_CONFIGURED"`

Workflow

Reviewing Calendar

Today's Agenda

When user says "what's on my calendar today" or "show today's schedule":

1. Fetch today's events:

   gog calendar events --today --json
   

2. Present formatted agenda:

Week's Agenda

When user says "what's my week look like" or "show this week":

1. Fetch week's events:

   # Calculate date range for this week
   FROM_DATE=$(date +%Y-%m-%d)
   TO_DATE=$(date -v+7d +%Y-%m-%d)  # macOS
   
   # Fetch events in range
   gog calendar events --from "$FROM_DATE" --to "$TO_DATE" --json
   

2. Present grouped by day:

   # Week Agenda — Week of [Date]
   
   ## Monday, [Date]
   - 9:00 AM - 9:30 AM | Team Standup
   - 2:00 PM - 3:00 PM | Design Review

   - Total meetings: 15
   - Busiest day: Tuesday (3.5 hours)
   - Lightest day: Wednesday (0.5 hours)
   - Free afternoons: Wednesday, Friday
   

Finding Meeting Slots

When user says "find time for a meeting" or "when am I free":

1. Gather requirements:

   Let me find available meeting times. A few questions:
   
   1. **Duration**: How long should the meeting be? (30 min, 1 hour, etc.)
   2. **Date range**: When are you looking? (This week, next week, specific dates)
   3. **Time preferences**: Any time constraints? (Mornings only, after 2pm, etc.)
   4. **Attendees**: Anyone else's calendar to check? (If you have access)
   

2. Search for slots using freebusy:

   # Get busy periods
   gog calendar freebusy primary \
     --from "2026-01-29T00:00:00Z" \
     --to "2026-01-31T23:59:59Z" \
     --json
   

   Note: GOG CLI v0.9.0 doesn't have find-slots. Instead, use freebusy to get busy periods, then calculate free gaps between them. For example:

   • If busy: 9-10am, 2-3pm
   • Then free: 8-9am, 10am-2pm, 3-5pm

   Parse the busy periods and suggest slots in the free time.

3. Present options:

   # Available Meeting Slots
   
   ## Top 5 Options (60 minutes)
   
   1. **Wednesday, Jan 29 at 2:00 PM - 3:00 PM**
      - Ideal time: After lunch, before end of day
      - No conflicts
   
   2. **Thursday, Jan 30 at 10:00 AM - 11:00 AM**
      - Morning slot, good energy
      - No conflicts
   
   3. **Thursday, Jan 30 at 3:00 PM - 4:00 PM**
      - Afternoon slot

   4. **Friday, Jan 31 at 9:00 AM - 10:00 AM**
      - Early morning
      - No conflicts
   
   5. **Friday, Jan 31 at 1:00 PM - 2:00 PM**
      - Post-lunch
      - No conflicts
   
   ---
   
   **Recommendation**: Option 1 (Wed at 2pm) — Best mid-week timing
   
   Which slot works best? Or need more options?
   

Creating Events

When user says "schedule a meeting" or "create a calendar event":

1. Gather event details:

   Let me create that calendar event. I need:
   
   1. **Title**: What's the meeting about?
   2. **Date & Time**: When? (e.g., "Tomorrow at 2pm", "Jan 30 at 10am")
   3. **Duration**: How long? (30 min, 1 hour, 90 min, etc.)
   4. **Attendees**: Who should attend? (email addresses, comma-separated)
   5. **Location**: Where? (Zoom, physical location, or I can generate a meeting link)
   6. **Description**: Any agenda or notes?
   

2. Parse date/time:

   • Support natural language: "tomorrow at 2pm", "next Tuesday at 10am"
   • Convert to ISO8601: "2026-01-29T14:00:00Z"
   • Confirm timezone assumptions

3. Present proposed event:

   ## Proposed Event
   
   **Title**: Q2 Planning Meeting
   **Date**: Wednesday, January 29, 2026
   **Time**: 2:00 PM - 3:00 PM (1 hour)
   **Attendees**:
   - alice@company.com
   - bob@company.com
   - carol@company.com
   **Location**: Zoom (meeting link will be generated)
   **Description**: Discuss Q2 goals, budget allocation, and team priorities.
   
   **Conflicts check**: ✅ No conflicts found for you
   
   ⚠️  **Note**: Cannot check attendees' availability without access to their calendars.
   
   Does this look correct? Any changes needed?
   

4. Request confirmation:

   Ready to create this event? It will:
   - Add to your calendar
   - Send invitations to all attendees
   - Generate meeting link (if applicable)
   
   Reply "yes, create" to confirm.
   

5. Only create with explicit confirmation: "yes, create" or "create it"

6. Create event:

   # Calculate end time from duration
   START_TIME="2026-01-29T14:00:00Z"
   END_TIME="2026-01-29T15:00:00Z"  # 1 hour later
   
   gog calendar create primary \
     --summary "Q2 Planning Meeting" \
     --from "$START_TIME" \
     --to "$END_TIME" \
     --attendees "alice@company.com,bob@company.com,carol@company.com" \
     --location "Zoom" \
     --description "Discuss Q2 goals, budget allocation, and team priorities." \
     --with-meet \
     --json
   

   Note:

   • Use primary as the calendar ID for the user's main calendar
   • --summary is the event title (not --title)
   • --from and --to are absolute times (not --start and --duration)
   • --with-meet automatically generates a Google Meet link

7. Confirm creation:

   ✅ **Event Created**
   
   Event ID: event_abc123
   Title: Q2 Planning Meeting
   When: Wednesday, Jan 29 at 2:00 PM
   Invitations sent to: 3 attendees
   
   **Next steps**:
   - Prepare agenda?
   - Send pre-read materials via email?
   - Add this to your task list as prep?
   

8. Offer email draft (optional):

   Would you like me to draft an email to attendees with:
   - Meeting details
   - Agenda
   - Pre-read or prep instructions

Failure Modes / Troubleshooting

GOG Not Configured

Symptom: Dynamic context shows GOG_NOT_CONFIGURED

Resolution:

1. Inform: "GOG CLI is not configured. See: skills/gog/_shared/references/gog-interface.md"
2. Suggest: "Run gog auth login to authenticate with calendar access"
3. Offer: "I can still help you plan scheduling manually"

Ambiguous Date/Time

Symptom: User says "schedule meeting tomorrow" without specifying time

Resolution:

1. Ask: "What time tomorrow? (e.g., 2pm, morning, afternoon)"
2. If still vague, suggest: "Would 2:00 PM work? (mid-afternoon, typical meeting time)"
3. Always confirm parsed date/time before creating

Timezone Confusion

Symptom: User is in different timezone than system

Resolution:

1. Check system timezone: date +%Z
2. Ask user: "I'm showing times in [TZ]. Is that correct for you?"
3. If mismatch, clarify: "So 2pm your time is [X]pm [TZ], correct?"
4. Always display timezone in event confirmations

No Available Slots

Symptom: Calendar is fully booked, no free slots found

Resolution:

1. Inform: "Your calendar is packed for [date range]. No [duration] slots available."
2. Suggest alternatives:
   • "Extend to next week?"
   • "Shorten meeting to [shorter duration]?"
   • "Consider before 9am or after 5pm?"
3. Show least-conflict options: "These times have only 1 conflict..."

Attendee Email Typo

Symptom: User provides malformed email address

Resolution:

1. Detect invalid format (no @, invalid domain)
2. Warn: "The email '[address]' doesn't look valid. Please double-check."
3. Ask: "Did you mean [suggested correction]?"
4. Don't create event with invalid emails

Conflict with Existing Event

Symptom: Proposed time overlaps with existing event

Resolution:

1. Warn: "⚠️ Conflict detected: You have '[Event Title]' at that time."
2. Ask: "Should I:
   • Find a different time?
   • Create anyway (double-booked)?
   • Reschedule the conflicting event?"
3. Require explicit confirmation for double-booking

Safety Rules

1. Never create events without confirmation - Always show proposal and request "yes, create"
2. No modifications without confirmation - Editing events requires explicit approval
3. Timezone awareness - Always clarify and confirm timezone in summaries
4. Privacy in invites - Don't include sensitive info in event titles/descriptions
5. Invitation transparency - Tell user who will receive invitations before creating

Safe Test

To safely test this skill using only user@example.com:

Test 1: View Agenda (Read-Only, Always Safe)

In Claude Code:

1. Load gog-calendar skill
2. Say: "Show today's agenda"
3. Verify output includes:
   • Events for today (or "No events" if empty)
   • Time, title, location, attendees
   • Summary with meeting count and free blocks

Test 2: Find Slots (Read-Only, Always Safe)

1. Say: "When am I free for a 30-minute meeting tomorrow?"
2. Verify output includes:
   • List of available time slots
   • Duration specified
   • Recommendation
3. Confirm no events are created

Test 3: Create Event (Draft-to-Self Only, Safe)

1. Say: "Schedule a test meeting with user@example.com tomorrow at 3pm, 30 minutes, test meeting"
2. Review proposed event
3. Say: "yes, create"
4. Verify event is created
5. Check your calendar to confirm event appears
6. Delete the test event afterward

See skills/gog/_shared/references/testing.md for complete test plan.

Notes

• This skill integrates with:

  • gog-email-triage: Calendar conflicts inform email prioritization
  • gog-email-draft: Can draft meeting invitations or agenda emails
  • gog-tasks: Meeting prep can become tasks
  • gog-followups: Track meeting follow-ups

• Consider creating event templates for recurring meetings (1:1s, standups)

• For recurring events, user should use calendar client directly (more complex to create via CLI)

• Smart scheduling tips:

  • Batch meetings on certain days, leave other days meeting-free
  • Suggest "No Meeting Fridays" if calendar is too full
  • Recommend buffer time between back-to-back meetings

• If GOG supports it, integrate with video conferencing (auto-generate Zoom links, etc.)

• Future enhancement: Analyze meeting patterns and suggest optimization
