Example Prompts

Try asking Claude:

• "Schedule a 30-minute meeting with Alice and Bob sometime next week"
• "Find a time when the engineering team is all free on Tuesday"
• "Show me my calendar for this week"
• "When is everyone available for a 1-hour planning session?"
• "Block off 2-4pm on Friday for focused work"

Scenarios

display (default)

View-only calendar display. User can navigate weeks but cannot select times.

bun run src/cli.ts show calendar --scenario display --config '{
  "title": "My Week",
  "events": [
    {"id": "1", "title": "Meeting", "startTime": "2025-01-06T09:00:00", "endTime": "2025-01-06T10:00:00"}
  ]
}'

meeting-picker

Interactive scenario for selecting a free time slot when viewing multiple people's calendars.

• Shows multiple calendars overlaid with different colors
• User can click on free slots to select a meeting time
• Selection is sent back via IPC
• Supports configurable time slot granularity (15/30/60 min)

bun run src/cli.ts spawn calendar --scenario meeting-picker --config '{
