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.

Security

Grade A, and why

obd 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 10d 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

CarsXE — OBD Code Decoder

Decode an OBD diagnostic trouble code (DTC) provided in $ARGUMENTS using the CarsXE OBD Codes Decoder API.

Steps

  1. Parse $ARGUMENTS to extract the OBD code (required). Example: /carsxe:obd P0300

  2. If no code is provided, ask: "Please provide an OBD code to decode (e.g., /carsxe:obd P0300)."

  3. Make an HTTP GET request:

    GET https://api.carsxe.com/obdcodesdecoder?key=<CARSXE_API_KEY>&code=<CODE>&source=claude_plugin
    

    Replace <CARSXE_API_KEY> with the value of the environment variable CARSXE_API_KEY.

  4. Present the decoded information clearly:

    • Code (e.g., P0300)
    • Description of the fault
    • System affected (engine, transmission, etc.)
    • Possible causes
    • Suggested fixes or next steps (if returned)
  5. Add helpful context — e.g., whether this is a serious code that requires immediate attention or a minor issue.

  6. Handle errors gracefully (invalid code format, no data found, auth error).

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.

obd 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 265 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.
