Car Lease Decoder

Q: How do I know the Car Lease Decoder output is good?

The skill verifies itself against its own quality checks: The money factor is converted to APR and the markup question is raised; Total lease cost is computed, not just the payment; Mileage exposure uses the user's real miles; Every trap carries a dollar exposure and a protective ask.

Decode a car lease offer — the money factor converted to APR, the cap-cost math, mileage and disposition traps, and what to negotiate. Use when asked to decode my car lease, is this lease deal good, what's a money factor, or review this lease before I sign. Produces the real-numbers decode (money factor → APR, total lease cost), the trap list with dollar exposure, and the negotiation points dealers expect to concede.

What to give it

▸The offer sheet — payment, term, miles/year, drive-off; ideally: money factor, residual %, cap cost, fees

▸The car — model and MSRP (residuals and negotiability vary)

▸Your driving reality — honest annual miles; the mileage trap is priced per your number

▸The alternative — buying the same car, if they want the comparison (chain to `car-tco`)

✅ 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.

✓The money factor is converted to APR and the markup question is raised

✓Total lease cost is computed, not just the payment

✓Mileage exposure uses the user's real miles

✓Every trap carries a dollar exposure and a protective ask

✓The disclaimer appears verbatim

⚠️ What it refuses to do

Do not evaluate the payment — payments are the costume; APR and total cost are the deal

Do not accept the money factor as a mystical constant — it's a rate with a markup

Do not use the leased mileage in the math — use the driven mileage

Do not ignore the end-of-lease pages — that's where the cheap payment gets paid back

Do not declare lease vs buy universally — it depends on miles, years, and taxes; point to the calculator
