macOS Calendar Assistant

---

name: macos-calendar-assistant description: Manage macOS Calendar with OpenClaw in IM-first workflows (Telegram/Discord/Feishu/iMessage/Slack), including screenshot-to-schedule extraction, idempotent create/update, move/extend/reschedule, reminders, conflict checks, daily review sync, and duplicate cleanup. Use when users ask to add/edit/move/postpone events, parse schedule screenshots/chat messages, adjust weekly plans into daily execution, or keep calendar and review notes in sync.

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 3. Prefer idempotent writes: - scripts/upsert_event.py (create/update/skip) 4. Apply alarm if requested: - scripts/set_alarm.py --uid --alarm-minutes 5. For hygiene, run duplicate scan: - scripts/calendar_clean.py --start --end

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

swift scripts/list_calendars.swift

List events in range

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)

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

Result is one of: CREATED, UPDATED, SKIPPED. Use --dry-run for preview.

Legacy direct add (always creates)

python3 scripts/add_event.py --title "..." --start "..." --end "..."

Set alarm by UID

python3 scripts/set_alarm.py --uid "EVENT_UID" --alarm-minutes 15

Move event (legacy utility)

swift scripts/move_event.swift "Team sync" "Work" "2026-03-07T10:00:00+08:00" 60 --search-days 7
optional precise match:
--original-start "2026-03-06T10:00:00+08:00"

Prefer upsert_event.py for most rescheduling flows; use move_event.swift for direct title-based move when needed.

Duplicate scan / cleanup

python3 scripts/calendar_clean.py --start "2026-03-01T00:00:00+08:00" --end "2026-03-08T23:59:59+08:00"
python3 scripts/calendar_clean.py --start "..." --end "..." --apply --confirm yes --snapshot-out ./delete-plan.json

Upcoming events (within 2 hours)

python3 scripts/within_2h.py

Environment + tests

python3 scripts/env_check.py
python3 scripts/regression_test.py
scripts/smoke_test.sh

Daily auto-check notifier

scripts/install.sh     # run env check + install cron from config.json
scripts/uninstall.sh   # remove cron

Extraction & scheduling heuristics (from real usage)

1. Speaker ownership from chat screenshots - Treat the user's message bubble as primary intent. - Treat counterpart bubbles as constraints (availability/travel window), not direct auto-create tasks.

2. Conflict policy - If user explicitly says "override" (for example, "replace this slot"), allow replacing an existing slot and reschedule the displaced event. - If not explicit, warn and ask for a choice before overwriting.

3. Time-window intent parsing - Phrases like "4–6 PM for the other person" should first be interpreted as an availability window. - Convert to a formal event only after user confirmation.

4. Reschedule priority - Prefer moving flexible events (workouts/optional blocks) before strategic P0 work blocks. - Do not auto-move P0 items unless user explicitly requests.

5. Confirmation prompt template - Use: "I identified X as your intent and Y as counterpart constraints. I will apply Z. Confirm?" - Keep it short; avoid over-confirming when intent is explicit.

Constraints

macOS only (EventKit + Calendar permission required)

Default timezone comes from config.json.timezone (fallback Asia/Shanghai) when user does not specify

Use --apply only after reviewing dry-run output
