3. Confirm: "✅ Reminder set: <task>" + due date if applicable

Deleting a reminder

1. Extract task name; use fuzzy: true if unsure of exact wording
2. POST /delete_reminder
3. Check count: if 0, say "⚠️ No reminder found matching '<task>'"

Updating a reminder

1. Extract current name and what to change
2. POST /update_reminder with only the changed fields
3. Confirm what was changed

Listing reminders

1. GET /list_reminders (add ?list=X if user specifies a list)
