- 4-week implementation roadmap:
- Week 1: Foundation (detection, parsing, basic display)
- Week 2: Mail App Integration (viewer, actions)
- Week 3: Advanced Features (Graph API sync)
- Week 4: Calendar Sync Integration (two-way sync)
Key capabilities:
- Parse ICS calendar files (text/calendar content type)
- Extract event details (summary, attendees, method, status)
- Detect cancellation vs invite vs update vs request
- Display calendar events in TUI with beautiful formatting
- Accept/Decline/Tentative/Remove actions
- Integration path with Microsoft Graph API (future)
Testing:
- Unit tests for parsing cancellations and invites
- Test fixture with real Outlook calendar example
- All tests passing
