Prerequisites

Before installing the extension, make sure you have the Gemini CLI installed and your GEMINI_API_KEY environment variable set.

You can get a Gemini API key from Google AI Studio.

macOS / Linux — add to your shell profile for persistence:

macOS / Linux

echo 'export GEMINI_API_KEY=your_gemini_api_key_here' >> ~/.bashrc
source ~/.bashrc

If you use Zsh (default on macOS), replace ~/.bashrc with ~/.zshrc.

Windows — PowerShell (current session):

Windows PowerShell (current session)

$env:GEMINI_API_KEY="your_gemini_api_key_here"

Windows — PowerShell (persist across sessions):

Windows PowerShell (persist)

[System.Environment]::SetEnvironmentVariable("GEMINI_API_KEY","your_gemini_api_key_here","User")

Windows — Command Prompt:

Windows Command Prompt

setx GEMINI_API_KEY "your_gemini_api_key_here"

After setx, restart your terminal for the variable to take effect.

Installation

Install the extension from the GitHub repository:

Terminal

gemini extensions install https://github.com/carsxe/carsxe-gemini-extension.git

During installation, Gemini CLI prompts you for your CarsXE API key. If you do not have a key yet, sign up and get one from the CarsXE developer dashboard.

If you skipped that prompt, or you want to change your API key after installing, run:

Configure API Key

gemini extensions config carsxe

This stores your API key securely in the system keychain.

Skills (Auto-invoked)

Gemini will automatically use the CarsXE tools when it detects relevant queries. For example:

"What can you tell me about VIN WBAFR7C57CC811956?" — triggers the vehicle-specs skill
"Does this car have any recalls? VIN: WBAFR7C57CC811956" — triggers the vehicle-recalls skill
"My check engine light is on with code P0300" — triggers the obd-decoder skill
"How much is a 2012 BMW X5 worth? VIN WBAFR7C57CC811956" — triggers the market-value skill
