Apple Reminders

Overview

apple-reminders is a built-in native command backed by EventKit. It exposes five verbs — list, create, update, complete, delete — over reminder titles, due dates, lists, priorities, notes, and completion state. Every call prints one JSON envelope to stdout.

The command is small, but three of its behaviours fail silently and successfully: a mistyped list name, an unparseable due date, and a truncated read all return ok: true. Most of this skill exists to keep those three from turning into wrong answers or misplaced tasks.
