Our review
Creates macOS Calendar events with tiered sound alarms and paired Reminders to ensure events are never missed.
Strengths
- Multi-tier sound alarms with custom sounds for different lead times
- Always paired with Reminders for dual notification channels
- Detailed instructions for system notification setup
- Ready-to-use templates for various scenarios
Limitations
- macOS only, requires Calendar and Reminders automation permissions
- Approved sounds are limited to a predefined list
- Relies on user having notification settings configured correctly
When you need to create an important event with reliable, audible reminders to ensure it is never missed.
For informal events or when the user prefers simple visual reminders without sound.
Security analysis
CautionThe skill relies on Bash to run osascript commands that create calendar events and reminders with user-supplied data. While the intent is legitimate productivity automation, the AI must construct AppleScript strings with potentially unescaped user input, creating injection risk. No destructive or exfiltrating actions are included, but the use of powerful system tools warrants caution.
- •Uses Bash to execute osascript with user-provided event details, which could lead to AppleScript injection if inputs are not properly sanitized.
- •Opens System Settings via URL scheme (open x-apple.systempreferences...), though benign.

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 alarmentries (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"
TodoWrite Task Templates

2. Create Calendar event with 6-tier sound alarms (Blow, Sosumi, Pop, Glass, Ping, Funk)
3. Create 3 Reminders (TOMORROW, TODAY morning, due-time)
4. Verify event and reminders created
5. Report full schedule to user
Template B: Create Event from User Description
1. Ask user for: event name, date/time, duration, location
2. Create Calendar event with 6-tier sound alarms
3. Create 3 Reminders
4. Verify event and reminders created
5. Report full schedule to user
Template C: Test Notification Setup
1. Create test Calendar event 3 min in future with sound alarms (1 min, 2 min tiers)
2. Create test Reminder 2 min in future
3. Wait for user confirmation of notifications
4. Clean up test event and reminders
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
