Field notes
The project reads MTG Arena’s diagnostic Player.log through open file descriptors, then maps match events to short-form commentary and local speech synthesis. Installation uses a Python virtual environment and optional Kokoro dependencies, with operating-system voice fallbacks listed for macOS, Windows, and Linux. The site also describes an eight-utterance variation window and tempo-based backlog pruning intended to keep fast combat from producing delayed narration.
