This is trying to use the word agent to make it sound cool, but it doesn't make a case for why it's particularly about agents and not just basic level AI stuff.
> The agent code is nothing more than a Python script that relies on the openai-agents-python library to run an AI agent backed by an LLM served via an OpenAI-compatible API.
The openai-agents-python code is useful for writing agents but it is possible to use it to write code that isn't very agentic. None of the examples are very agentic.
