Key Concepts

Short IDs

Reminders have UUIDs like x-apple-reminder://AB12CD34-.... The CLI displays the first 8 characters as a short ID (AB12CD34). You can pass any unique prefix to commands — rem complete AB1 works if it matches exactly one reminder.

Natural Language Dates

The --due flag accepts natural language:

rem add "Call dentist" --due tomorrow
rem add "Submit report" --due "next friday at 2pm"
rem add "Quick task" --due "in 30 minutes"
rem add "Wrap up" --due eod

Supported patterns: today, tomorrow, next monday, in 3 hours, eod, eow, 5pm, 2026-02-15, and more. See references/dates.md for the full list.

Priority Levels

Level	Flag value	AppleScript value
High	--priority high	1 (range 1-4)
Medium	--priority medium	5
Low	--priority low	9 (range 6-9)
None	--priority none	0

Output Formats

All read commands support -o / --output:

• table (default) — formatted table with borders
• json — machine-readable JSON
• plain — simple text, one item per line

The NO_COLOR environment variable is respected.

URL Storage

macOS Reminders has no native URL field. rem stores URLs in the notes/body field with a URL: prefix and extracts them for display.

Common Workflows

Daily review

rem overdue                          # Check what's past due
rem upcoming --days 1                # See today's reminders
rem list --list Work --incomplete    # Focus on work items

Batch operations with JSON

rem export --list Work --format json > backup.json
rem import backup.json --list "Work Archive"

Scripting with JSON output

# Get overdue count
rem overdue -o json | jq 'length'

# List all incomplete reminder titles
rem list --incomplete -o json | jq -r '.[].name'

Public Go API

For programmatic access, use go-eventkit directly:

import "github.com/BRO3886/go-eventkit/reminders"

client, _ := reminders.New()
r, _ := client.CreateReminder(reminders.CreateReminderInput{
    Title:    "Buy milk",
    ListName: "Shopping",
    Priority: reminders.PriorityHigh,
})
items, _ := client.Reminders(reminders.WithCompleted(false))

See go-eventkit docs for the full API surface.

Limitations

• macOS only — requires EventKit framework and osascript
• No tags, subtasks, or recurrence — not exposed by EventKit/AppleScript
• --flagged filter is slower (~3-4s) — falls back to JXA since EventKit doesn't expose flagged
• List deletion may fail on some macOS versions
