It has no API, MCP server or documented command for another agent, it is five days old, and it rebuilds itself from the main branch every six hours by default. **Caddy.** Caddy is a free iMessage and RCS assistant in public beta that watches connected mail, calendars and work apps and asks before sending email or changing data. No outside agent can call it, and no status page, changelog or security contact was found, though its iOS app ships every week or two. ## Before you call either ### Atticus 1. Don't plan to call Atticus from another agent. It takes requests only from its own shortcut and typing box 2. If a user runs Atticus beside you, expect it to move windows and type into apps on the same Mac 3. Point a user who wants pinned versions to Settings > About & Updates to turn off self-update ### Caddy 1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to. 2. Expect Caddy to ask the owner before it sends email or creates an invite. ## Questions ### Which is better for AI agents, Atticus or Caddy?

It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
