  • reminders_tasksPriority, tags, subtasks. `startDate` is set via `update`, not `create`; on `read` it scopes the due-date window alongside `endDate`. Cross-list moves unsupported.
  • reminders_subtasksStored in the notes field (human-readable in Reminders.app).
  • reminders_listsRename via `name` → `newName`.
  • calendar_eventsOn reads, `startDate` and `endDate` are wall-clock values in the event's `timeZone`; timed events also include `startDateISO` and `endDateISO` as unambiguous UTC timestamps when available. Use the ISO fields to schedule or compare events. All-day events do not include them. All-day is inferred from…
  • calendar_calendarsWithout a date range, every calendar EventKit reports, with its `source` and write permission. With `startDate`/`endDate`, calendars holding ≥1 event in the window, annotated with an event count.
