Our review

Creates macOS Calendar events with tiered sound alarms and paired Reminders to ensure notifications are never missed.

Strengths

  • Uses long, distinct sounds for each reminder tier, recognizable by ear.
  • Combines Calendar sound alarms with separate Reminders for redundancy.
  • Automatically checks and guides notification settings to ensure alerts work.

Limitations

  • Requires macOS and the Calendar app.
  • Only works if system notifications are enabled.
  • Predefined approved sounds list, no custom sounds.
When to use it

Use this skill for important events where missing a reminder is critical (doctor appointments, key meetings, birthday parties).

When not to use it

Do not use for trivial or daily recurring events that don't warrant multiple sound reminders.

Security analysis

Safe
Quality score88/100

The skill only uses AppleScript to create local calendar events and reminders on macOS. It does not involve network access, data exfiltration, or destructive commands. The Bash tool is allowed but only used for harmless operations like opening system preferences. There is no risk of code injection or unauthorized access.

Calendar Event Manager

Create macOS Calendar events with tiered sound alarms and paired Reminders so events are never missed across Mac and iOS.

CRITICAL RULES (Hard-Learned Truths 2026-02-12)

These rules are NON-NEGOTIABLE. Violating any of them defeats the purpose of this skill.

1. Calendar + Reminders ALWAYS Together

Every event MUST create BOTH:

  • Calendar event with multiple sound alarm entries (custom sound per tier)
  • Reminders (3 minimum) as a separate notification channel

Never create one without the other.

2. Use sound alarm, NOT display alarm

-- CORRECT: audible alert with custom sound
make new sound alarm at end of sound alarms with properties {trigger interval:-60, sound name:"Glass"}

-- WRONG: silent visual banner only
make new display alarm at end of display alarms with properties {trigger interval:-60}

Each alarm supports its own sound name property. Use DIFFERENT sounds for different tiers so the user knows which alert level it is by sound alone.

3. ONLY Long Sounds (>= 1.4 seconds)

Short sounds get missed and ignored. NEVER use sounds under 1.4 seconds.

APPROVED sounds only:

| Sound | Duration | Use For | | --------- | -------- | ------------------------- | | Funk | 2.16s | At event time (loudest) | | Glass | 1.65s | 1 hour before | | Pop | 1.63s | Morning-of / 3 hrs before | | Sosumi | 1.54s | Day-before | | Ping | 1.50s | 30 min before | | Submarine | 1.49s | Alternative | | Blow | 1.40s | Gentle early reminder |

BANNED sounds: Hero, Basso, Bottle, Purr, Frog, Morse, Tink (all < 1.4s)

4. Multiple Early Reminders Are Mandatory

Minimum alarm tiers for any event:

| Tier | Trigger | Calendar Sound | Reminder | | --------------- | --------- | -------------- | ----------------- | | 1 day before | -1440 min | Blow | "TOMORROW: ..." | | Morning-of 9 AM | Absolute | Sosumi | "TODAY: ..." | | 3 hours before | -180 min | Pop | (via Calendar) | | 1 hour before | -60 min | Glass | (via Calendar) | | 30 min before | -30 min | Ping | (via Calendar) | | At event time | 0 min | Funk | Due-time reminder |

5. macOS Notification Settings Prerequisite

Calendar notifications must be enabled in System Settings:

  • System Settings > Notifications > Calendar > Allow Notifications = ON
  • Alert style = Banners or Alerts
  • Play sound = ON

Open with: open "x-apple.systempreferences:com.apple.Notifications-Settings.extension"

AppleScript Patterns

Full Event Creation (Copy-Paste Ready)

tell application "Calendar"
    tell calendar "Calendar"
        set newEvent to make new event with properties {summary:"EVENT_NAME", start date:date "DATE_STRING", end date:date "DATE_STRING", location:"LOCATION", description:"NOTES"}
        tell newEvent
            -- 1 day before: gentle
            make new sound alarm at end of sound alarms with properties {trigger interval:-1440, sound name:"Blow"}
            -- 3 hours before: noticeable
            make new sound alarm at end of sound alarms with properties {trigger interval:-180, sound name:"Pop"}
            -- 1 hour before: clear
            make new sound alarm at end of sound alarms with properties {trigger interval:-60, sound name:"Glass"}
            -- 30 min before: time to go
            make new sound alarm at end of sound alarms with properties {trigger interval:-30, sound name:"Ping"}
            -- At event time: loudest
            make new sound alarm at end of sound alarms with properties {trigger interval:0, sound name:"Funk"}
        end tell
    end tell
    reload calendars
end tell

Paired Reminders Creation

tell application "Reminders"
    set defaultList to default list
    -- Due-time reminder
    make new reminder in defaultList with properties {name:"EVENT_NAME", due date:EVENT_DATE, body:"LOCATION\nNOTES"}
    -- Day-before
    make new reminder in defaultList with properties {name:"TOMORROW: EVENT_NAME", due date:(EVENT_DATE - 1 * days), body:"Event tomorrow! LOCATION"}
    -- Morning-of at 9 AM
    set morningDate to date "DATE_STRING"
    set time of morningDate to 9 * hours
    make new reminder in defaultList with properties {name:"TODAY: EVENT_NAME", due date:morningDate, body:"Today! LOCATION"}
end tell
