What it does

The plugin teaches Claude about your synced data in ~/Documents/alto-index/. It knows the folder structure, frontmatter format, and deep links for every data source. Ask Claude about your notes, reminders, calendar, messages, or contacts naturally, no special syntax needed.

Every item includes native app deep links so Claude can reference the original note, reminder, event, or contact directly.

Commands

  • /altoindex:today: daily briefing across all sources
  • /altoindex:search [query]: search across all sources
  • /altoindex:summary [source]: summarize a data source
  • /altoindex:notes [query]: browse or search Apple Notes
  • /altoindex:reminders [list]: browse Apple Reminders
  • /altoindex:calendar [date]: browse Apple Calendar events

Auto-invoked skill

  • “what did I write about X in my notes?”
  • “do I have any reminders about Y?”
  • “find Z in my contacts”
  • “what meetings did I have last week?”
  • “what was I browsing yesterday?”
