What it does

Car Lease Decoder is an agent skill from mohitagw15856/pm-claude-skills. 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.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/worked-example.md`).

The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked to decode my car lease
  • Is this lease deal good
  • Whats a money factor
  • Review this lease before I sign

Example prompts

  • “/car-lease-decoder”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Money factor first: MF × 2400 = APR. Quote it back to the dealer as a rate. A "0.00325 money factor" is 7.8% — a number the customer can…
  2. The lease equation, shown: depreciation (cap cost − residual) + rent charge ((cap + residual) × MF) + taxes/fees. Every offer decodes into…
  3. Cap cost is the price — negotiate it exactly like a purchase price before ever discussing payment. "What payment do you want?" is the trap…
  4. The mileage math, personalized: (your real miles − allowance) × per-mile charge × term. At 15k real vs 10k leased and $0.25/mile, that's…
  5. The end-of-lease gauntlet: disposition fee, wear standards ("excessive" defined by whom?), and the early-exit table — decode each with its…

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Car Lease Decoder loads about 1.1k tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 110 tokens; SKILL.md has 595 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~110
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
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.

Car Lease Decoder Skill

Leases are quoted in a dialect designed to prevent comparison: money factors instead of interest rates, cap costs instead of prices, payments instead of totals. This skill translates everything into the two numbers that matter — the effective APR and the total cost of the lease — then walks the traps that live in the back pages.

Not quite this? Use used-car-decoder when you are buying a used car from a listing rather than leasing.

What This Skill Produces

  • The translation — money factor × 2400 = the APR they didn't say; cap cost vs MSRP vs negotiated price
  • Total lease cost — payments + drive-off + fees + likely end charges, one number
  • The trap list — mileage math, disposition fee, wear-and-tear standards, early-exit exposure, each priced
  • Negotiation points — what's routinely movable, with the asks

Required Inputs

Ask for these only if not provided:

  • 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)

Framework

  1. Money factor first: MF × 2400 = APR. Quote it back to the dealer as a rate. A "0.00325 money factor" is 7.8% — a number the customer can compare to their credit union. Also ask what MF the captive lender published — marked-up MF is dealer profit and negotiable.
  2. The lease equation, shown: depreciation (cap cost − residual) + rent charge ((cap + residual) × MF) + taxes/fees. Every offer decodes into this; anything that doesn't reconcile is a question.
  3. Cap cost is the price — negotiate it exactly like a purchase price before ever discussing payment. "What payment do you want?" is the trap question; the decode answers with cap cost.
  4. The mileage math, personalized: (your real miles − allowance) × per-mile charge × term. At 15k real vs 10k leased and $0.25/mile, that's $3,750 hiding behind a cheaper payment.
  5. The end-of-lease gauntlet: disposition fee, wear standards ("excessive" defined by whom?), and the early-exit table — decode each with its dollar exposure and the one protective ask (e.g., waived disposition if leasing again).

Output Format

Lease Decode: [car] — [term]/[miles]

The two numbers: effective APR [n.n]% · total lease cost $[n] ([payments] + [drive-off] + [fees] + [projected end charges])

The equation, reconciled [depreciation + rent charge + fees vs their payment math — matches / gap of $n asks why] Trap table | Trap | The line | Your exposure | The ask | Negotiation points — cap cost, MF markup, mileage tier, disposition — each with wording Lease vs buy pointer: [one honest paragraph; full math via car-tco]

End verbatim: "This is a plain-language reading, not financial advice — lease structures and taxes vary by jurisdiction; confirm anything load-bearing before signing."

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
  • The disclaimer appears verbatim

Anti-Patterns

  • 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

Example Trigger Phrases

  • "Decode my car lease."
  • "Is this lease deal good?"
  • "What's a money factor?"
  • "Review this lease before I sign."
