Why it matters
Money tasks are tedious but high-stakes, which is exactly where a careful agent helps: it does the checking and paperwork while a person keeps the final say. It is one of 65 sightings filed under Finance on Agent Sightings (number 22 by interest), and one of 48 involving ChatGPT Agent.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into ChatGPT Agent or any similar agent and adjust the details to your situation.
Finance task: play online math games in agent mode. Tabulate numbers, mark uncertainties, and do not file, pay, or submit until I confirm.
Tip: Keep the agent in 'propose, don't pay' mode: let it gather numbers and draft messages, and approve any payment or account change yourself.
