Used Car Listing Writer — Claude Skill for Private-Party Car Ads
Give Claude your car's real specs — year, mileage, features, honest condition, price — and get back a complete, trustworthy listing for Facebook Marketplace, Craigslist, or a dealer website, ready to post. One named job, executed end to end. Not a prompt pack.
What makes it different from every generic "AI listing generator" is a hard guardrail: if you didn't supply a spec, a history detail, or a price, it does not make one up. It leaves a [bracketed placeholder] you fill before posting. Honesty sells cars — disclosed flaws build the trust that gets replies.
What you get
- used-car-listing-writer/SKILL.md — the complete Claude skill file (readable plain text, no code)
- README.md — 60-second install quick-start for Claude Code, Claude.ai, or Cursor
- Delivered as one zip, instant download
A real example — verbatim from the skill file
Input: FB Marketplace, private seller. 2016 Honda CR-V EX, 92,450 mi, AWD, 2.4L, automatic, silver/gray cloth, $14,900 OBO. Sunroof, backup camera, new front tires + brakes ~2 months ago. One owner, clean title, no accidents. Small dent rear hatch. Selling — growing family needs a 3rd row. Vestal NY.
Output:
2016 Honda CR-V EX AWD — 1 Owner, Clean Title, New Tires & Brakes
A one-owner family SUV I've owned since new. Honest rundown:
- ✅ AWD — confident in NY snow and rain
- ✅ Power sunroof + backup camera
- ✅ New front tires & brakes (~2 months ago)
- ✅ Roomy cargo area + cloth interior
- ✅ 92,450 miles, automatic, 2.4L engine
Condition: One owner, clean title, no accidents. Honest note — there's a small dent on the rear hatch (happy to send a close-up). [Optional: add a line on how it drives day-to-day — buyers trust a quick, honest note here.]
Asking $14,900 OBO. Only selling because our growing family needs a third row.
Message me to set up a time to see it and test drive in [Vestal, NY]. Cash or [your accepted payment].
— Listing completeness: HIGH. — [Fill before posting]: add 4–6 photos incl. the dent and odometer; confirm VIN.
Inputs and outputs
- You supply: platform (Marketplace / Craigslist / dealer site), seller type, year/make/model/trim, mileage, price, features actually present, honest condition and title status — whatever you have. Anything missing becomes a [bracket], never a guess.
- You get back: a headline, 4–8 benefit bullets each tied to a real supplied spec, a plain-spoken condition section, a soft no-pressure CTA, a fill-before-posting checklist, and a LOW/MED/HIGH completeness read.
- Format: plain text, shaped to the platform you name (short and scannable for Marketplace, fuller for Craigslist, professional third-person for a dealer site).
- Model compatibility: tested with Claude (Claude Code and Claude.ai). Install instructions for Claude Code, Claude.ai, and Cursor are in the README.
When to use it — and when NOT to
- Use it when you're a private seller or small dealer with the facts in hand and a blank text box in front of you — a first listing, or a rewrite of one that isn't getting messages.
- Do NOT use it for pricing or appraisal. It never estimates market value, KBB numbers, MPG, horsepower, or how fast the car will sell, and it won't write "runs great" or "well-maintained" unless those are your words. Salvage or rebuilt title? It goes plainly up top — never omitted, never softened. If you ask it to add a feature the car doesn't have, it declines.

Honest claims only
No promises about how fast your car sells or what it sells for — no tool can honestly make them. This skill drafts a trustworthy ad from the facts you supply; the facts, the photos, and the price stay yours. It is not an appraisal, pricing tool, or vehicle-history report — confirm VIN, title, and odometer before posting and follow your platform's rules and local disclosure laws.
