Apple Reminders CLI (remindctl)

Use remindctl to manage Apple Reminders directly from the terminal.

When to Use

✅ USE this skill when:

• User explicitly mentions "reminder" or "Reminders app"
• Creating personal to-dos with due dates that sync to iOS
• Managing Apple Reminders lists
• User wants tasks to appear in their iPhone/iPad Reminders app

When NOT to Use

❌ DON'T use this skill when:

• Scheduling Understudy chat alerts or recurring automations → use the schedule tool instead
• Calendar events or appointments → use Apple Calendar
• Project/work task management → use Notion, GitHub Issues, or task queue
• One-time or recurring in-chat notifications → use the schedule tool
• User says "remind me" but means an Understudy alert in this chat → clarify first

Setup

• Install: brew install steipete/tap/remindctl
• macOS-only; grant Reminders permission when prompted
• Check status: remindctl status
• Request access: remindctl authorize
