The Job
A shopper demonstrated agent mode doing the chore everyone hates: finding discount codes that actually work. He fed it a screenshot of an Amazon product page and had the agent hunt down valid codes and apply the savings before checkout.
The Prompt — try it yourself
I am about to buy [product] at [store]. Find every currently valid discount, coupon, or promo code, verify which ones actually work, and tell me the best final price before I check out.
Field note: swap the bracketed details for your own, keep the approval steps — and make the agent show its work before it acts. That's the whole trick.— V.
