This example demonstrates how to create and run a simple LLM agent using the Agent Development Kit (ADK). The agent is configured with a basic system instruction and responds to a user prompt, showcasing the fundamental interaction flow in ADK.

Requirements

• Python 3.10+
• A Google API key set as an environment variable (GOOGLE_API_KEY)

Steps for running this example in the shell

1. Install dependencies:

python -m venv .venv

# macOS/Linux:
source .venv/bin/activate

# Windows Command Prompt:
.venv\Scripts\activate.bat

# Windows PowerShell:
.venv\Scripts\Activate.ps1

pip install -r requirements.txt

2. Export your API key as an environment variable:

export GOOGLE_API_KEY="sk-..." # Windows cmd: set GOOGLE_API_KEY="sk-..." # Windows PowerShell: $env:GOOGLE_API_KEY="sk-..."

3. Run the script:

python basic_agent.py

Output

The agent will respond to user prompts, for example as follows:

User: Hello, agent!
Agent: Hello there! How can I assist you today?
