By instantiating the `PragmaticProgrammerAGIAgent` class and passing it the `OPENAI_API_KEY`, you can then instantiate the `PragmaticStarterKit` by passing the agent object as a parameter. The `PragmaticStarterKit` class contains a method that creates the entire structure for the Pragmatic Starter Kit. This kit incorporates DDD, Docker Compose, GitHub Actions, and pytest based on a predefined definition. This method invokes the `create_system` method of the agent, which in turn generates the required code to setup this system. The generated code is then written to a Python file named "PragmaticStarterKit.py". This demonstrates the power and the advanced capabilities of the `PragmaticProgrammerAGIAgent` in creating high standard and advanced systems just from a simple definition.
