• Google API key for Gemini models
• Google Custom Search Engine (CSE) API key and ID

Setup

1. Clone the repository:

   git clone https://github.com/yourusername/gemini-terminal-agent.git
   cd gemini-terminal-agent
   

2. Create a virtual environment (recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows: venvScriptsactivate
   

3. Install dependencies:

   pip install -r requirements.txt
   

4. Create a .env file in the project root with your API keys:

   GOOGLE_GENAI_API_KEY=your_gemini_api_key_here
   SEARCH_ENGINE_API_KEY=your_google_api_key_here
   SEARCH_ENGINE_CSE_ID=your_cse_id_here
   DEFAULT_MODEL=gemini-2.5-flash-preview-04-17
   

Setting Up Google Search Engine

To use the web search functionality, you need to set up a Google Custom Search Engine:

1. Get a Google API Key:

   • Go to Google Cloud Console
   • Create a new project or select an existing one
   • Navigate to “APIs & Services” > “Library”
   • Search for “Custom Search API” and enable it
   • Go to “APIs & Services” > “Credentials”
   • Create an API key and copy it (this will be your SEARCH_ENGINE_API_KEY)

2. Create a Custom Search Engine:

   • Go to Programmable Search Engine
   • Click “Create a Programmable Search Engine”
   • Add sites to search (use *.com to search the entire web)
   • Give your search engine a name
   • In “Customize” > “Basics”, enable “Search the entire web”
   • Get your Search Engine ID from the “Setup” > “Basics” page (this will be your SEARCH_ENGINE_CSE_ID)

3. Get a Gemini API Key:

   • Go to Google AI Studio
   • Sign in with your Google account
   • Go to “API Keys” and create a new API key
   • Copy the API key (this will be your GOOGLE_GENAI_API_KEY)
