A command for looking up vehicle specifications from the vehicle’s year, manufacturer, and model through the CarsXE service. An optional trim identifies a specific version, such as an LE or Sport model.

Use it to retrieve available trims, engine and drivetrain details, fuel information, body style and dimensions, and standard features for a specified vehicle.

It avoids manually searching multiple vehicle pages for compatible trims, engines, equipment, dimensions, and fuel information. It also tells you what details are needed when the vehicle description is incomplete.

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.

Token cost

What it costs to keep this loaded

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	$0.00000	$0.00365
Opus 5	$0.00000	$0.00182
Sonnet 5	$0.00000	$0.00073
Haiku 4.5	$0.00000	$0.00036

Security

Grade A, and why

ymm 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 today.

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

CarsXE — Year / Make / Model Lookup

Look up vehicle data by Year, Make, and Model using the CarsXE YMM API.

Steps

Parse $ARGUMENTS to extract:
- year (required): 4-digit year (e.g., 2020)
- make (required): vehicle manufacturer (e.g., Toyota, Ford)
- model (required): vehicle model (e.g., Camry, F-150)
- trim (optional): specific trim level (e.g., LE, Sport, Limited)
Example: /carsxe:ymm 2020 Toyota Camry LE
If year, make, or model are missing, ask: "Please provide year, make, and model (e.g., /carsxe:ymm 2020 Toyota Camry)."
Make an HTTP GET request:
```
GET https://api.carsxe.com/v1/ymm?key=<CARSXE_API_KEY>&year=<YEAR>&make=<MAKE>&model=<MODEL>&source=claude_plugin[&trim=<TRIM>]
```
Replace <CARSXE_API_KEY> with the value of the environment variable CARSXE_API_KEY. Only include trim if the user specified it.
Present the results in a clean format:
- Available trims (if not specified)
- Engine options, transmission, drivetrain
- Fuel type and economy
- Body style and dimensions
- Standard features
Handle errors gracefully (no data found, invalid params, auth error).

Notes

To list available years, makes, models, or variants first, use /carsxe:ymm-options.

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.

ymm is a command published in the GitHub repository carsxe/carsxe-claude-plugin (2 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 365 tokens. 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.
