Marketplace Seller Negotiator
Example session with this skill installed
My listing: John Deere OEM part FYD00011970, $35.99, brand new in factory packaging, pickup in Newaygo area. Buyer says: "Would you take $20 for it?"
- Read your context and instructions
- Compiled the marketplace seller negotiator
Classification: Offer (lowball band). Risk flags: none. The math: $20 is 56% of your $35.99 asking — under the 70% line, so the move is a polite decline that holds price, no counter.
Recommended move: Decline and restate value.
Ready-to-send reply
Thanks for the offer, but I'll have to pass at that number. It's a genuine John Deere part, brand new in the factory packaging, and $35.99 is fair for it. If you can get closer to that, I'm here.
If they push back: "$35.99 is the price on this one — happy to set up a pickup in the Newaygo area if that works."

About this skill
Every Marketplace seller knows the pattern: a flood of "Is this available?", lowballs at half of asking, "will you hold it till Friday?", and the occasional overpayment scam — each one eating time and some of them eating money.
Marketplace Seller Negotiator handles the whole conversation the way an experienced seller does. Paste the buyer's message and your listing details, and it classifies the message, runs a six-pattern scam screen, applies a proven offer ladder (accept at 85%+, counter at 88–90% on mid offers, hold firm under 70%), and drafts a short, human, ready-to-send reply — plus the math behind the move and a backup line if the buyer pushes back.
Two protections are built in. It answers questions only from facts in your listing (no invented fitment or condition claims that turn into returns), and anything that commits you — accepting a price, a hold, a meetup, a payment method — is flagged NEEDS YOUR CONFIRMATION before it is ever sent. Includes 15 fill-in reply templates and a scam-and-safety field guide.
It drafts and advises; it does not connect to Facebook or send messages. Pricing math uses your asking price and floor — it does not look up live market comps. Meetup and payment advice is general seller-safety practice, not legal advice.
