Decode a used-car listing before you drive an hour to see it — what the seller's phrasing is hiding, the history-check items that matter, a test-drive and inspection checklist ordered by cost-of-miss, the questions that make evasive sellers visible, and the walk-away signs ranked 🔴🟡🟢. Use when someone says 'is this car listing legit', 'what should I check on a used car', 'decode this ad', or is about to buy their first car. Produces a listing decode, the viewing checklist, and the negotiation frame. Not a mechanic — and it says which checks need one.

What changed
🗣 Say this to your agent
“Is this car listing legit?”“What should I check on a used car?”“Decode this ad.”
What to give it
▸The listing text and photos described, plus price and the car — make/model/year/mileage
▸The buyer — first car or fifteenth, mechanical comfort level, who else might inspect with them
▸Budget truth — the price ceiling *including* the first-year surprises buffer (insurance, immediate maintenance)
▸Country — for the verify-local flags on history checks and paperwork (this skill never asserts registry procedures)
✅ The bar it holds itself to
Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.
✓Every decoded phrase quotes the actual listing — no generic
✓suspicion without a receipt
✓All registry/history/paperwork items carry verify-local flags with
✓search terms, never asserted procedure
✓The checklist is executable by the stated mechanical comfort level;
✓pro-inspection items say so
✓Repair costs appear as classes, never invented precise quotes
✓The walk-away list is present and absolute — items where
⚠️ What it refuses to do
Do not diagnose remotely — signs and their severity class, yes;
"that's definitely the clutch," no
Do not assert country procedures (title transfer, history
registers, deposit law) — flag and route
Do not let a good price override the walk-away list anywhere in
