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 | $0.00030 | $0.01523 |
| Opus 5 | $0.00015 | $0.00762 |
| Sonnet 5 | $0.00006 | $0.00305 |
| Haiku 4.5 | $0.00003 | $0.00152 |
Grade A, and why
design-ev-charging-setup 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design EV Charging Setup
Design a safe, code-compliant home EV charging installation by selecting the appropriate charging level, specifying electrical requirements, and preparing for professional installation.
Why This Is Best Practice
Adopted by: DOE "EV Everywhere" national program, NEC Article 625 (adopted by all 50 states), SAE International (J1772 connector standard used by all non-Tesla EVs), NFPA electrical safety standards, utility EV programs nationwide
Impact: 80% of EV charging occurs at home (DOE AFDC data); proper Level 2 installation adds $1,000–$2,500 in home value (Zillow EV data, 2022); incorrect installation causes fire risk — 34% of EV charging incidents involve improper extension cords or undersized wiring; utility time-of-use (TOU) optimization saves $400–$900/year on charging costs
Why best: NEC Article 625 and SAE J1772 together define the physical, electrical, and safety requirements for EV charging; designing within these standards ensures safety, maximum charging speed, and insurance/warranty compliance
Sources: SAE J1772 "Electric Vehicle and Plug-in Hybrid Electric Vehicle Conductive Charge Coupler" standard; DOE EV Everywhere "Charging at Home" guide; NEC 2023 Article 625 "Electric Vehicle Charging System"
Steps
-
Determine daily charging need — Calculate: average daily miles driven ÷ EV's efficiency (miles/kWh) = daily kWh needed. Add 20% buffer for range variation. This determines minimum charging speed required.
-
Evaluate Level 1 vs. Level 2 vs. DC Fast — Level 1 (120V, 12A standard outlet): adds 3–5 miles/hour — sufficient if daily driving <40 miles and car charges overnight. Level 2 (240V, 24–80A, EVSE required): adds 15–30 miles/hour — standard for most EV owners. DC Fast Charge (Level 3): commercial only, not home-installable.
-
Select EVSE power level — Calculate required EVSE output: daily kWh ÷ available charging hours (typically 8–12 hours overnight) = minimum kW. Standard recommendation: 32A (7.7 kW) for 150–200 miles/day capable; 48A (11.5 kW) for large trucks/SUVs or high daily mileage. Do not over-spec beyond your vehicle's onboard charger limit — charging at 48A into a vehicle with a 7.2 kW onboard charger wastes panel capacity.
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.

design-ev-charging-setup is a skill published in the GitHub repository jeffreytse/grimoire-core (4 stars, last pushed 21d ago), licensed MIT. It adds 30 tokens to every session and 1,523 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
