Prompt
Compare [OPTIONS] for office work, video calls and light photo editing. My budget is USD 900. My priorities, in order, are battery life, weight, screen, price. First check whether I supplied exact product names, specifications or links. If not, ask me for the missing options and stop; do not invent candidates. Use only supplied facts or current sources you can actually access. For prices and specifications, give the source and date when available; otherwise mark them unknown. Make a concise table with my priorities as rows and the products as columns. Explain the main trade-offs. Recommend one only when the evidence supports it; otherwise give a shortlist and the exact details I need to verify. Flag local availability, warranty and final price before purchase. Do not invent specifications, ratings or discounts.

Example output
Actual tested output. The notes used for this result are an example, not a real event. This box is not copied. Replace the notes above with your own before you paste the prompt.
You did not supply exact product names, specifications, or links. The request still says [OPTIONS]. Send the options you want compared. I will not invent candidates, ratings, discounts, or specs. For each option, send a listing or spec source with: current price in USD (your budget is 900), battery life, weight, screen details, and the date of that source. Also send local availability, warranty, and the final price before purchase. Your use is office work, video calls, and light photo editing. Your priorities, in order, are battery life, weight, screen, and price. When those listings are here, the table will use your priorities as rows and these products as columns.
