Why it matters
This is the classic promise of AI agents: a helper that handles errands and reminders on your behalf. Real cases like this show how close that promise is today. It is one of 57 sightings filed under Personal Assistant on Agent Sightings (number 51 by interest), and one of 1 involving Bob.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Bob or any similar agent and adjust the details to your situation.
Run on my laptop only. Handle my calendar, expenses, invoices and email, but only with tools you ship yourself, and ask me before any action that goes outside the house.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
