Give your shopping shortlist a winner
Why now: Agent shopping makes it useful to distinguish choosing a suitable item from authorizing its purchase.

What you'll need
- A non-sensitive shopping shortlist with prices, relevant features, a budget and your priorities.
Steps
- Paste the options, including any delivery charges and your must-have features.
- Run the prompt to get one recommendation grounded only in your notes.
- Check the price calculation and trade-off before making your own purchase decision.
The prompt
Help me choose from this shopping shortlist using only the information provided. Treat my budget and must-have features as hard limits, then apply my stated priorities in order. Do not invent product details or assume missing costs are zero. Write plain text with no Markdown formatting, under 120 words, as one paragraph of three sentences. First, name the recommended option and its total cost including any stated delivery charge. Second, explain why it best matches my priorities. Third, state one trade-off from the supplied details. If no option qualifies or essential information is missing, explain that instead of forcing a recommendation. Do not make or authorize a purchase. Here is my shortlist: [paste your shortlist, budget and priorities]
What you should get
One three-sentence paragraph under 120 words: a qualifying option and total cost, a reason following the stated priorities, and one supported trade-off; no invented features or purchase authorization.
Tested example: Tested on sample input
Input
I need a desk lamp for evening sketching. My total budget is 45, including delivery. An adjustable arm is essential. After that, I prefer a smaller base, then a lower price. Lamp A costs 28 plus 5 delivery, has a fixed arm and a small base. Lamp B costs 39 with free delivery, has an adjustable arm and a small base. Lamp C costs 32 plus 4 delivery, has an adjustable arm and a wide base.
Output
I recommend Lamp B at a total cost of 39, including free delivery. It meets your 45 budget and adjustable-arm requirement, and its small base takes priority over Lamp C’s lower price. The trade-off is that Lamp B costs 3 more than Lamp C’s delivered total of 36.
