PlantUMLSteps, a new extension for PlantUML, enables step-by-step playback of sequence diagrams. Developed using an LLM, it parses PlantUML files, generates SVGs for each step, and creates an HTML viewer with navigation controls.

The project demonstrates how LLMs can streamline initial development by handling boilerplate tasks, allowing developers to focus on core logic. It showcases the process of iteratively building a tool through LLM assistance, from syntax design to implementation.
