Fetch events from Apple Calendar for next 7 days using AppleScript.

Display in DOS style:

UPCOMING (7 days)

| Date       | Time  | Event              | Calendar |
|------------|-------|--------------------|----------|
| Jan 17 Sat | 09:15 | AI Builder Co-work | Personal |
| Jan 17 Sat | 19:00 | Bear's Wine Bar    | Personal |

Show Notes column from events.md if HAL has context for any event.

2. View week/month

Ask: "View this week, next week, or full month?"

Fetch appropriate date range from Apple Calendar and display.

3. Add event

Ask: "Event name, date, time, calendar?"

After info gathered:

1. Show the entry for confirmation
2. Use AppleScript to create event in Apple Calendar
3. Add to events.md Upcoming section with Source: "HAL"
4. Confirm: "Added to Apple Calendar and HAL"

AppleScript for creating event:

tell application "Calendar"
    tell calendar "[calendar name]"
        make new event with properties {summary:"[event name]", start date:date "[date string]", end date:date "[end date string]"}
    end tell
end tell

4. Sync now

Pull events from Apple Calendar (next 30 days).

Compare to events.md:

• New events in Apple Calendar → add to events.md with Source: "Apple Calendar"
• Events in events.md but not in Apple Calendar → mark or ask user

Report: "Synced. +X new events, Y already tracked."

Update events.md with any changes.

5. Edit event notes

Show upcoming events from events.md.

Ask: "Which event to edit?"

Then ask: "New notes for this event?"

Update the Notes column in events.md.

Tags to suggest:

• [networking] for networking events
• [work] for work events
• [personal] for personal events

6. Exit

Say: "Closing Calendar. Returning to HAL." End the application mode.

Sync Logic

When syncing, match events by:

1. Date + Time + Event name (exact match)
2. If close match (same date, similar name), ask user

For new events from Apple Calendar:

• Add to events.md Upcoming section
• Source: "Apple Calendar"
• Notes: empty (user can add later)

After Each Action

Ask: "Another action? (y/n)"

If yes: show main menu again. If no: exit gracefully.

Style

• Keep the DOS aesthetic
• Be concise
• Stay in "application mode" until exit
• Use AppleScript for all Apple Calendar operations
