# macos-calendar-assistant

Use bundled scripts for reliable Calendar.app operations.

## Workflow

1. Extract title, start/end, timezone, calendar, location, notes, alarm.
2. Check conflicts before writing:
   - `scripts/list_events.swift <start_iso> <end_iso>`
3. Prefer idempotent writes:
   - `scripts/upsert_event.py` (create/update/skip)
4. Apply alarm if requested:
   - `scripts/set_alarm.py --uid <event_uid> --alarm-minutes <n>`
5. For hygiene, run duplicate scan:
   - `scripts/calendar_clean.py --start <iso> --end <iso>`

## Calendar routing defaults

- Workout / Run / Training → `Training`
- Work / Meeting / Client → `Work`
- Product / Development / Building → `Product`
- Personal / Social / Travel → `Life`
- If unspecified: prefer writable iCloud/CalDAV calendars over local calendars.

> Note: Calendar names vary by user setup. Map the intent to the closest local calendar name before writing.

## Commands

### List calendars
```bash
swift scripts/list_calendars.swift
```

### List events in range
```bash
swift scripts/list_events.swift "2026-03-06T00:00:00+08:00" "2026-03-06T23:59:59+08:00"
```

Output includes `uid` for follow-up alarm/edit operations.

### Idempotent create/update (recommended)
```bash
python3 scripts/upsert_event.py \
  --title "Team sync" \
  --start "2026-03-06T19:00:00+08:00" \
  --end "2026-03-06T20:00:00+08:00" \
  --calendar "Work" \
  --notes "Agenda" \
  --location "Online" \
  --alarm-minutes 15
```
