Why it matters

Small, repetitive tasks eat more of the week than anyone likes to admit. Cases like this show an agent taking a chore off someone's plate end to end, not just suggesting what to do. It is one of 196 sightings filed under Productivity on Agent Sightings (number 82 by interest), and one of 91 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.

Help me search Facebook Marketplace and tabulate results in Sheets. Break it into steps, show your work, and wait for confirmation before anything irreversible, paid, or outbound.

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.
