Why it matters
Notes are only useful if you can find and connect them later. Agents that organise, summarise and link information make a personal knowledge base far easier to keep up. It is one of 60 sightings filed under Knowledge & Notes on Agent Sightings (number 17 by interest), and one of 122 involving Microsoft 365 Copilot.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Microsoft 365 Copilot or any similar agent and adjust the details to your situation.
I want an agent to take on this workflow, show its working, and wait for approval on anything that changes a system or contacts someone. The tool in the source case was Microsoft 365 Copilot.
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.
