I made this agent to tutor physics with diagrams! It's basic and my first agent and actually only has a single tool to call, but I really enjoyed building the agent loop from scratch rather than using a framework. Uses 4.1 for fast but reasonably intelligent, then o3 I think for diagram generation.
