Prismer execution contract

This is the uniquely named prismer-apple-reminders skill, adapted from Hermes. Use the actual tools exposed by the executing host; examples using terminal, process, delegate_task, vision_analyze or browser_* are not tool registrations. Missing dependencies do not hide this skill. Report command startup, version, account/permissions and task-specific live verification separately. Use task-owned artifact paths and existing user authorization; do not change shared accounts, Runtime/provider configuration, global security settings or unrelated work. See NOTICE.md and LICENSE for resource provenance. Runtime availability and upstream-entry suppression are owned by the integration layer.

Apple Reminders

Use remindctl to manage Apple Reminders directly from the terminal. Tasks sync across all Apple devices via iCloud.

Prerequisites

Resolve SKILL_ROOT to this installed directory and run python3 "$SKILL_ROOT/scripts/readiness.py" reminders, then remindctl --version. The startup probe does not authorize EventKit or verify iCloud/notifications. The audited 0.1.1 lacks --alarm: enable the alarm examples below only when the installed add/edit help explicitly supports that flag. Otherwise report the early-notification requirement blocked; do not silently substitute a due date.

• macOS with Reminders.app
• Install: brew install steipete/tap/remindctl
• Grant Reminders permission when prompted
• Check: remindctl status / Request: remindctl authorize

When to Use

• User 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 on their iPhone/iPad

When NOT to Use

• Scheduling agent alerts → use the actual Prismer task scheduler, not an invented cronjob tool
• Calendar events → use Apple Calendar or Google Calendar
• Project task management → use GitHub Issues, Notion, etc.
• If user says "remind me" but means an agent alert → clarify first

Quick Reference

View Reminders

remindctl                    # Today's reminders
remindctl today              # Today
remindctl tomorrow           # Tomorrow
remindctl week               # This week
remindctl overdue            # Past due
remindctl all                # Everything
remindctl 2026-01-04         # Specific date

Manage Lists

remindctl list               # List all lists
remindctl list Work          # Show specific list
remindctl list Projects --create    # Create list
remindctl list Work --delete        # Delete list

Create Reminders

remindctl add "Buy milk"
remindctl add --title "Call mom" --list Personal --due tomorrow
remindctl add --title "Meeting prep" --due "2026-02-15 09:00"

Due Time vs Alarm / Early Nudge

When the installed version supports both, --due and --alarm are different fields:

• --due sets the reminder's due date/time.
• --alarm sets the EventKit alarm/notification trigger. Timed due reminders may default to an alarm at the due time, but pass --alarm explicitly when the user asks for an earlier nudge.

For a reminder due at 2:00 PM with a notification 30 minutes earlier:

remindctl add --title "Hairdresser" --due "2026-05-15 14:00" --alarm "2026-05-15 13:30"

To edit an existing reminder:

remindctl edit 87354 --due "2026-05-15 14:00" --alarm "2026-05-15 13:30"

The Reminders UI may show or group the item by the alarm time because that is when the notification fires. Verify with JSON instead of assuming the due time moved:

remindctl today --json

Read the actual version's JSON schema; the following fields are version-dependent:

• dueDate: actual due time
• alarmDate: notification / early nudge time

Apple's public EKReminder docs list only reminder-specific properties. Alarm support comes from inherited EKCalendarItem behavior exposed by remindctl's --alarm flag.

Complete / Delete

remindctl complete 1 2 3          # Complete by ID
remindctl delete 4A83 --force     # Delete by ID

Output Formats

remindctl today --json       # JSON for scripting
remindctl today --plain      # TSV format
remindctl today --quiet      # Counts only

Date Formats

Accepted by --due and date filters:

• today, tomorrow, yesterday
• YYYY-MM-DD
• YYYY-MM-DD HH:mm
• ISO 8601 (2026-01-04T12:34:56Z)

Rules

1. Clarify Apple Reminders versus an agent scheduled task only when intent is ambiguous.
2. Use the user's stated content/time authorization; clarify only missing fields.
3. Use --json for programmatic parsing
4. Record host timezone and resolved timestamp. Read back the exact created ID; help/JSON success alone does not prove the notification was delivered.
