Your coding agent makes your product demo video.

Agencies charge $5,000-$15,000 for a 60-second product demo. This skill lets
Claude Code, Cursor, or any coding agent make one from your repo, on your
machine, for $0, script, animated composition from your real components,
frame-perfect recording, captions, AI voiceover plan, self-scoring sound
design, and music mixing.

A Vouch project by
Ansh Grover. The
Vouch demo is the
reference output, everything on the site was made with this pipeline.

Install

npx skills add Anshgrover23/product-demo-playbook

or clone and copy skills/product-demo/ anywhere your agent reads
instructions. Prereqs: Node 20+, ffmpeg, npx playwright install chromium.

Then ask your agent:

Use the product-demo skill to make a launch demo video for the app in
this repo. Run the whole pipeline yourself, start to finish. Ask me in
chat when you need something: script approval, the voiceover audio, the
music file. Track progress in demo/PROGRESS.md so we can resume anytime.

That is the only prompt. The agent orchestrates all eight steps and asks
you in conversation at the moments it needs a human: approving the script,
pasting the tagged voiceover block it writes into MiniMax or ElevenLabs,
and pasting its music prompt into a generator.
