Blackboard / Whiteboard Explainer Video Skill · Voice-Driven Pen

Make Khan Academy style explainer videos: the pen draws while the voice explains. You describe the video, Claude writes a scene file, one command renders an MP4. Supports blackboard lessons, tutorials that draw arrows and circles over product screenshots, and cutting podcasts / videos into vertical shorts with hand-drawn animation, with one-command switching between chalk-on-blackboard and marker-on-whiteboard.
