Record a narrated, human-paced demo video of a web feature with agent-browser: a smooth pointer, typing a viewer can read, no dead air, clicks paced to land on the narration, and a camera directed shot by shot from a screenplay, as a sharp 2560x1440 60 fps MP4. Use when the user asks to demo a feature, record a walkthrough, make a demo or screen recording for a PR, docs or release notes, or show someone what changed in the UI.
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 A demo shows a person what changed in under a minute. Dead air comes from you thinking between commands, so never record while exploring. Explore first, write a screenplay of beats, then let the bundled player run it with no model in the loop. Needs `agent-browser` (0.38.1 or later), `ffmpeg` and Node 22 or later, on macOS, Linux or Windows. The scripts need no packages. The player drives agent-browser even when the project has its own browser driver: it needs Chrome's 3x screencast, the pointer's timing and the stepped scroll, which a test runner does not give. The player is `scripts/record.mjs` in this skill's folder. The narration comes from the `add-voiceover` skill, in the folder next to this one (`<skill-dir>/../add-voiceover`); without it, record a silent video. Install it with `npx skills add jamdotdev/skills --skill add-voiceover`. ## 1. Rehearse without recording Open the page, run `agent-browser snapshot -i`, and run every action once. Pick CSS selectors that still match after earlier steps change the page; refs like `@e3` go stale. …

How to install
mdr add jamdotdev/jam-plugin/record-demo@sha256:fae334065fd17da0The line at the top of this page pins the label git:20261102.2494dbe, 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.
