Sold anywhere, take down everywhere
For someone clearing out a closet across several marketplaces. One inventory record holds each item, a cron job checks every live listing for a sold signal, and the moment one sells the quantity locks to zero and every other listing is flagged to take down.
What it does
- Identifies the item from phone photos: brand, size, condition and a value estimate
- Prices each marketplace backward from the amount you want to keep after fees and shipping
- Writes a listing per platform within its title and length rules
- Checks every live listing every 10 minutes for a sold out signal
- Locks the inventory to zero on the first sale and lists the other listings to remove
Your approval boundaries
Approval requiredThese actions always wait for your yes:
- Publishing each listing in your own signed in browser
- Taking down the other listings after a sale
- Accepting any offer
You decide what happens next.
More about this workflow
This setup is for online sellers and resale shops juggling listings, orders and buyers. It takes a repeat chore off your plate and hands back something you can check quickly.
First, it identifies the item from phone photos: brand, size, condition and a value estimate. Next, it prices each marketplace backward from the amount you want to keep after fees and shipping. Then it writes a listing per platform within its title and length rules. After that, it checks every live listing every 10 minutes for a sold out signal. Finally, it locks the inventory to zero on the first sale and lists the other listings to remove. It works with your store admin, marketplace APIs and photo storage, each on its own login with limited access.
You get the prep work done and waiting for you. The agent stops and asks for your yes before publishing each listing in your own signed in browser, taking down the other listings after a sale and accepting any offer, and says plainly if a step cannot be undone.
“Shopify quantity is the lock.”

Steps
Do these in order. Test on old data before it touches live work.
- 1Connect Shopify with its own login, not yours. Grant read orders and products.
- 2Connect eBay with its own login, not yours. Grant read scopes for orders and listings.
- 3Set up Photo storage. Keep it to read-only access to one photo folder.
- 4Paste the prompt where your harness takes instructions. See the note under the Copy button.
- 5Do a dry run on old or test data first. Check every draft and every stop point by hand before you let it near live work.
- 6Read its log after the first real run. Only widen access once a week of runs looks clean.
Safeguards and trust score
The score describes this example setup’s access, approval boundaries, ability to undo changes, and scope.
Can draft things that send or spend, so it sits close to risky actions.
Waits for a yes on: publishing each listing in your own signed in browser, taking down the other listings after a sale, accepting any offer.
Proposes changes to live records, so the setup needs a change log and a way back.
Runs on its own login across 3 tools. Fewer connections means a smaller blast radius.
How to raise it
- Access: Take away its ability to send, post or spend. Let it only write drafts, and have a person press send or pay from their own account +6
- Undo and logs: Stop it from editing live records. Have it write the change as a proposal you apply, and keep a log of every change with a way to roll it back +3
- Scope: Cut it down from 3 connected tools to the 2 it needs most, each with its own limited login instead of your full account +2
Do all of these to reach 89, up from 78.
