Turns a codebase into a demo narrative that has value — picks which capabilities earn screen time, structures them into beats, sets per-section durations, and writes the voiceover text at a speakable pace. Use at the scripting stage of a demo video, when writing or revising demo/storyboard.json, when the user asks what the demo should show, or when a demo feels like a feature tour instead of a story.
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
# Demo Scripting A demo fails for one of two reasons: it shows the wrong things, or it shows the right things in an order nobody cares about. Both are decided here, before a single frame is recorded. ## Start from the decision, not the feature list The viewer is making a decision — adopt this, approve this, upgrade to this, or use this new capability. Write that decision down in `meta.audience` and let it eliminate material: everything that does not move that decision is cut, no matter how much work it took to build. Three questions to answer before writing any section: 1. **What does the viewer do today instead?** That is your `problem` beat, and the source of every honest comparison. 2. **What is the one thing they should remember?** If you cannot name it, the demo has no spine and will read as a tour. 3. **What would make them say "wait, go back"?** That is your `wow` beat. A demo with no such moment is documentation. If the user hasn't given you this, draft `demo/brief.md` from the codebase and confirm it. Do not skip to the storyboard — a storyboard built on a guessed audience gets rewritten. ## Choosing what to show …

How to install
mdr add lukaskellerstein/claude-my-marketplace/demo-scripting@sha256:2c52e0df3a347c87The line at the top of this page pins the label git:20260729.3efde9d, 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.
