Use when the user wants a Khan Academy style explainer video, a blackboard or whiteboard lesson, a hand-drawn chalk-talk animation, a short narrated video that teaches a concept ("explain X in a video", "explainer video", "teach X in 30 seconds"), or a tutorial that draws hand-written arrows, circles and captions over product screenshots ("draw over the UI", "annotated walkthrough"), or clips cut from a YouTube video or podcast where the speaker's real audio plays under a blackboard drawn to…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> Copy of the root SKILL.md for skills.sh discovery. The root file is the source of truth. # Khan Explainer A pen draws while a voice explains. Three modes, one renderer: - **Blackboard lesson.** A diagram drawn on a black board, Khan Academy style. - **Draw-over-UI tutorial.** Arrows, circles and numbered captions drawn over product screenshots. - **Real-audio clip.** A real person's voice, cut from a video, with the board drawn to their words. See "Real-audio clips". One scene file in, one MP4 out, in seconds. Free and local: HTML canvas, Playwright, macOS `say`, ffmpeg. No keys. Every mode renders as chalk on a blackboard or marker on a whiteboard, landscape or vertical. Made by Haider Farooq ([github.com/haiderfarooq3](https://github.com/haiderfarooq3/khan-explainer)). Free for anyone to use and change (MIT). **Core principle: the voice drives the clock.** A scene is a list of beats. A beat is one spoken clause plus the drawing that happens while it is said. The renderer speaks each beat first, measures it, and fits that beat's drawing to it. Never hardcode seconds or guess when a word lands. ## Workflow …

How to install
mdr add haiderfarooq3/khan-explainer/khan-explainer@sha256:5b58c9efc61af3c1The line at the top of this page pins the label git:20261011.326bf9b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
