Arrowproof is a tool that verifies LLM-generated architecture diagrams (Excalidraw) against the actual import graph of a codebase, marking arrows as verified, indirect, reversed, or missing. It also generates diagrams and step-by-step explainers from specs, and can run in CI to keep docs honest. It's interesting because it addresses a growing problem: hallucinated diagrams that look plausible but misrepresent the code.

Target audience: backend developers, devops, software architects
