Reminders

macOS Reminders

Manage macOS Reminders via the reminders script. Returns JSON. Zero dependencies — uses built-in macOS tools.

When to Use This Skill

Use this skill proactively, not only when the user explicitly asks:

• "Remind me to..." — create a reminder with a due date.
• User mentions a task or to-do — create a reminder or search for existing ones.
• "What do I need to do?" — list upcoming/incomplete reminders.
• "I finished X" or "Done with X" — mark the matching reminder as complete.
• User explicitly asks to look up, add, complete, edit, or delete reminders.

Running Commands

All commands use the reminders script in this skill's references/ directory. Determine the path relative to this SKILL.md file:

REMINDERS="$(dirname "<path-to-this-SKILL.md>")/references/reminders.sh"

On first run, macOS will prompt for Reminders access — click Allow.

Commands

Lists

$REMINDERS lists

Shows all reminder lists with total and incomplete counts.

List Reminders

$REMINDERS ls [<list-name>] [--all]

List reminders. By default shows only incomplete. If no list name given, shows across all lists.

$REMINDERS ls
$REMINDERS ls "Shopping"
$REMINDERS ls "Work" --all

Search (default)

$REMINDERS search <query> [--all]
$REMINDERS <query>                   # search is the default command

Search reminders by name and notes across all lists. By default excludes completed.

$REMINDERS search "buy milk"
$REMINDERS "dentist"
$REMINDERS search "groceries" --all

Add

$REMINDERS add --name <text> [--list <name>] [--due <datetime>] [--remind <datetime>] [--notes <text>] [--priority high|medium|low] [--flagged]

--name is required. If --list is omitted, uses the default list. If --due is provided without --remind, the remind-me date is set to the same value.

Dates must be ISO 8601 with time (e.g. 2025-02-15T10:00:00). Convert relative dates (e.g. "tomorrow at 9am") to absolute ISO 8601 before calling.

$REMINDERS add --name "Buy milk"
$REMINDERS add --name "Call dentist" --due 2025-02-15T09:00:00 --priority high
$REMINDERS add --name "Pick up package" --list "Errands" --notes "At the post office"

Complete

$REMINDERS complete <query> [--list <name>]

Mark a reminder as complete. Searches incomplete reminders by name. If multiple match, lists them.

$REMINDERS complete "Buy milk"
$REMINDERS complete "Buy milk" --list "Shopping"

Edit

$REMINDERS edit <query> [--list <name>] [options]

Find a reminder by name and apply changes. If multiple match, lists them.

$REMINDERS edit "Buy milk" --name "Buy almond milk"
$REMINDERS edit "Call dentist" --due 2025-02-20T14:00:00
$REMINDERS edit "Old task" --uncomplete

Delete

$REMINDERS delete <query> [--list <name>] [--yes]

Find a reminder by name and delete it. Asks for confirmation unless --yes is passed. Always use --yes to skip the interactive prompt.

$REMINDERS delete "Buy milk" --yes
$REMINDERS delete "Old task" --list "Shopping" --yes

Add List

$REMINDERS add-list --name <text>

Create a new reminder list.

$REMINDERS add-list --name "Projects"

Workflow

- [ ] 1. Set REMINDERS path relative to this SKILL.md
- [ ] 2. Run the appropriate command
- [ ] 3. If permission error → tell user to grant Reminders access in System Settings > Privacy & Security > Reminders
- [ ] 4. Parse and present results to the user

Proactive behaviors

• "Remind me to...": Create a reminder immediately. Parse the due date from context (e.g., "tomorrow morning" → next day at 9:00 AM). Confirm what you created.
• Task mentioned in conversation: If the user mentions needing to do something, offer to create a reminder or do it proactively if the intent is clear.
• "Done with X" / "I finished X": Search for matching reminders and mark them complete. Confirm what was completed.
• "What's on my list?": List incomplete reminders. Summarize by list if there are many.
