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 | $0.00048 | $0.00214 |
| Opus 5 | $0.00024 | $0.00107 |
| Sonnet 5 | $0.00010 | $0.00043 |
| Haiku 4.5 | $0.00005 | $0.00021 |
Grade A, and why
vehicle-specs 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.
What it actually says
When the user provides a VIN and asks about vehicle specs, details, or information:
- Call the CarsXE Specifications API:
GET https://api.carsxe.com/specs?key={CARSXE_API_KEY}&vin={VIN}&source=claude_plugin - Present the results in a clean, organized format covering:
- Basic info: Make, Model, Year, Trim
- Engine: type, cylinders, displacement, horsepower, torque
- Transmission & drivetrain
- Fuel type and economy (city/highway/combined)
- Body style, doors, seats
- Standard & optional equipment
- If the API key is missing, tell the user to set the
CARSXE_API_KEYenvironment variable.
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.

vehicle-specs is a skill published in the GitHub repository carsxe/carsxe-claude-plugin (2 stars, last pushed 2d ago), licensed MIT. It adds 48 tokens to every session and 214 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.
