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.

The file
Files
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
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 "$box_id" -- "lux status"Why Box
- Real desktop + Chrome — does GUI work headless setups can't.
- Two stream modes — 60fps WebRTC (Moonlight) for quality, VNC-over-HTTPS for reliability on restrictive networks.
- Auto-recorded demos — every Lux run produces a video artifact.
Prereqs
curl -fsSL https://box.ascii.dev/install | sh, then box login "$BOX_API_KEY" --json.
Limits
EU-only; 100 active VMs soft cap. For massive parallel headless browser fleets, dedicated browser providers (Browserbase) scale further; Box is best when you need a full machine behind the browser.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
