Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00176 | $0.03517 |
| Opus 5 | $0.00088 | $0.01758 |
| Sonnet 5 | $0.00035 | $0.00703 |
| Haiku 4.5 | $0.00018 | $0.00352 |
Grade A, and why
ev-buyer-helper scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

EV Buyer Helper
Caveat: this skill is one author's playbook + 5-scenario stress test. Verify state fees / CPO terms / EV credits / dealer practices against current sources before quoting numbers to a dealer or making financial decisions. Not tax, legal, or financial advice. last_verified: 2026-06-22 (federal credit termination re-verified against IRS)
⚠️ CRITICAL, FEDERAL EV CREDITS HAVE ENDED (as of 2026-06)
The One Big Beautiful Bill Act (OBBBA / Public Law 119-21, signed 2025-07-04) terminated all three federal clean-vehicle credits for any vehicle acquired after 2025-09-30:
- §30D New Clean Vehicle Credit ($7,500), TERMINATED.
- §25E Previously-Owned (Used) Clean Vehicle Credit ($4,000), TERMINATED.
- §45W Commercial Clean Vehicle Credit ($7,500, the lease pass-through), TERMINATED.
A vehicle acquired on or before 2025-09-30 (written binding contract + a payment, incl. a nominal deposit or trade-in, by that date) can still claim the credit even if placed in service later, but that window is closed for any 2026 purchase.
For any buyer purchasing now (2026): there is NO federal $7,500 / $4,000 / §45W EV credit. Do NOT quote these to a buyer or use them in OTD / net-price math. Only state/local rebates (where still funded) and manufacturer incentives remain.
The §30D / §25E / §45W mechanics below are retained as historical reference (eligibility for pre-2025-10-01 acquisitions, and in case Congress reinstates a credit). They do not apply to current purchases.
Sources: IRS FAQ Fact Sheet 2025-05 (modification of §§25C/25D/25E/30C/30D/45L/45W/179D under OBBB); IRS, accelerated termination of energy provisions under OBBB.
Narrow helper for EV-only buying scenarios: federal/state incentives, charging hardware transition, used-EV battery diligence. Use when buyer has already chosen an EV powertrain and needs the EV-specific layer on top of the standard OTD/negotiation flow.
Note (2026): the federal incentive layer is gone (see banner above); this skill's present-day value is the state rebate matrix, charging/SoH/range diligence, and used-EV battery checks. Treat all §30D / §25E / §45W content as historical.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ev-buyer-helper is a skill published in the GitHub repository DaizeDong/buy-me-a-car (5 stars, last pushed 8d ago), licensed MIT. It adds 176 tokens to every session and 3,517 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings.
