What this skill tells your AI

The instructions your AI receives, as published by hashgraph-online/awesome-codex-plugins in plugins/carsxe/carsxe-codex-plugin/skills/obd-decoder/SKILL.md and read by Ahel’s review.

When the user mentions an OBD/DTC code and wants to know what it means:

  1. Make an HTTP GET request to the CarsXE OBD Codes Decoder API:
    GET https://api.carsxe.com/obdcodesdecoder?key={CARSXE_API_KEY}&code={CODE}&source=codex_plugin
    
  2. Present the decoded fault clearly: code, description, system affected, possible causes, and suggested fixes.
  3. Add context on severity — whether it requires immediate attention or can wait.
  4. If the API key is missing, tell the user to set the CARSXE_API_KEY environment variable (see AGENTS.md).
