The source didn't share its exact prompt, so we wrote this from what it describes.

Here's a folder of photos of everything I want to sell before we move. Organize the photos into subfolders by item. Then, for each item, look up the correct Facebook Marketplace category name, research the average resale price, write a title and description, and output it all as a spreadsheet that matches Facebook's bulk upload template.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Turn a folder of item photos into a ready-to-upload Facebook Marketplace spreadsheet, with fair prices I can review.

Questions to ask me first:
- How many items, and where are the photos?
- Do you have Facebook's bulk upload template?
- Do you want to sell fast or get the best price, and are there items with known defects?

Inputs (fill in or confirm):
- Photo folder: [FOLDER]
- Facebook bulk upload template: [TEMPLATE FILE]
- Pricing goal: [FAST SALE / BEST PRICE]
- Notes on condition, model numbers or defects: [NOTES]

Rules:
- Group photos into one subfolder per item and list any you're unsure about.
- Use only real Facebook Marketplace category names that you've looked up, not invented ones.
- Base prices on used listings and say where each price came from; if there are no comps, say so.
- Don't put retail prices in descriptions, and note any defects I gave you.

Checkpoint: Show me the item folders and a sample of 5 rows before filling in the whole spreadsheet.

If you get stuck: If you can't identify an item from the photos, ask me instead of guessing.

Verify before you finish: Check that every row matches the template's columns and that the highest-value items' prices look sensible.

Output: A filled bulk upload spreadsheet and a short list of items whose prices I should double-check.

Done when: I've uploaded the spreadsheet and only need to attach photos to each listing.

Outcome

Getting ready to move, Dave Swift had close to a hundred items to sell on Facebook Marketplace. After photographing everything into one folder, Swift had Claude Cowork sort the photos into labeled subfolders by item, correctly pairing tricky cases such as a ukulele and its separate case. Claude then looked up Facebook's real category names (Swift notes Claude makes them up if not told to look), used sub-agents to research resale prices for several items at once, wrote descriptions and produced a spreadsheet in Facebook's bulk-upload template. Swift uploaded it with 'Create Multiple Listings' and only had to attach photos. Claude priced a patio furniture set too low, so Swift raised it to $1,000, and it tended to put retail prices in descriptions.
