Why it matters

Research is mostly gathering, cleaning and comparing. Handing that groundwork to an agent leaves the person with the part that needs judgment: deciding what the findings mean. It is one of 201 sightings filed under Research & Data on Agent Sightings (number 3 by interest), and one of 213 involving Claude.

How you could try it

Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude 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 Claude.

Saved

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.
