Record a product demo video by reading the product's own code and the craft of demo-making, not by guessing at either. Use when the user asks to record a demo, make a demo video, film the product, show the product working, or produce a launch clip. Also use when a demo already recorded is wrong, boring, or missed the point of the product. Needs the repo and a running instance.
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
# Record a demo of the product, from its own source ## The failure this exists to fix Cap's bundled `cap-demo` skill scouts the page at runtime and scores every anchor and button to pick a "CTA": `+3` if the text matches `/features|pricing|docs/`, `+2` for a background colour, `-5` for "sign up". Nothing in that scoring has any knowledge of the product it is pointed at. Run against a real site it produced this: ``` STORY=scroll cta=none accent=null cursor track synthesized: 182 moves, 0 clicks ``` No CTA found, so it scrolled. **Zero clicks** in a product demo. Nothing was demonstrated, because nothing in that pipeline knows what the product does. **You are not in that position.** You have the repo. Read it, decide what the demo should show, and write the storyboard yourself. That is the whole skill. ## Before any of that: you do not know how to make a demo video You know how to drive a UI and run an encoder. Those are the mechanics. A demo video is a **craft with its own rules**, and the first version of this skill had none of them, so the first demo it produced was four taps on a tab bar. That is …

How to install
mdr add calebnewtonusc/chewbacca/demo@sha256:d221d0dcb4116c74The line at the top of this page pins the label git:20260925.18c24b5, 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.
