Drive a real browser and Linux desktop in the cloud (computer use) — a full GUI with Chrome, a 60fps stream for visibility, and the Lux agent for automating clicks/typing/logins. Use for visual UI checks, logging into web apps, testing Electron apps, or any GUI task that can't be done over plain shell. Records demo videos automatically.
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
# Computer use: browser + desktop (Box) Use this when a task needs a **real GUI**, not just a shell: logging into a web app, validating a rendered UI, controlling Chrome, testing an Electron app, or recording a demo. Box runs a full Linux desktop with Chrome; the **Lux** agent automates desktop/browser interactions and auto-records the session. ## Recipe ```bash box_id="$(box new --json | jq -r 'select(.event == "ready") | .id')" # Get a live desktop stream URL (60fps WebRTC, or VNC over HTTPS on bad networks) box desktop "$box_id" --json # Automate a GUI goal with Lux (records to /home/user/lux-demos/) box ssh "$box_id" -- "lux start 'log in to example.com and screenshot the dashboard'" box ssh "$box_id" -- "lux run --max-steps 30" box ssh "$box_id" -- "lux status" ``` ## Why Box - **Desktop + Chrome built in** — 1920x1080 desktop with `computer` tools for agents, no desktop setup needed. No GPU: graphics run on the CPU. - **Two stream modes** — 60fps WebRTC (Moonlight) for quality, VNC-over-HTTPS for reliability on restrictive networks. - **Auto-recorded demos** — every Lux run produces a video artifact. ## Prereqs …

How to install
mdr add ariana-dot-dev/cloud-sandbox-vm-skills/computer-use-browser-desktop@sha256:01105b923c2dd0e3The line at the top of this page pins the label git:20261109.2f1d005, 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.
