# Teaser video Produce a launch-quality teaser (~30-45s) of a running app: storyboard it, film it by driving the real UI, cut it with ffmpeg, and hand back an MP4 plus a GIF for the README. The output must look like a product video, not a screen recording. The difference is direction - staging, framing, and rhythm - not resolution. Reference implementations live in `reference/`; they are working ESM modules, not pseudocode. Set up in a scratch directory - never inside the project: ```bash cp -r <skill>/reference/* "$SCRATCH/" && cd "$SCRATCH" && npm install export TEASER_BASE_URL="https://the-app.example.com" ``` `reference/package.json` declares `"type": "module"` and the three dependencies. Every script reads `TEASER_BASE_URL`, so nothing is hardcoded to one app. ## Before anything else: the two hard rules **1. Never trigger real-world side effects without explicit, itemized consent.** Filming a real app means clicking real buttons. Some of those send email, post publicly, charge money, or submit forms to third parties. Before you touch the app: - Enumerate every action in your storyboard that leaves the machine. - Tell the user exactly what each one does and how many times, then get agreement on the count. - Prefer a mode that stops short of the irreversible step (a preview, a dry-run, a confirmation gate you can film and then decline). There is no such thing as a read-only probe against a live system. A "diagnostic" click that lands in an already-running ses...
