Work with Apple Reminders synced to ~/Documents/alto-index/reminders/.
If $ARGUMENTS is provided, search reminders for that query or filter by list name.
If no arguments, show all reminders grouped by list:
- use Glob to find
~/Documents/alto-index/reminders/*/directories - count reminders in each list
- highlight reminders with due dates (show due_date from frontmatter)
- highlight flagged reminders
Always include the x-apple-reminder:// deep link from the link frontmatter field.
