Name/description match the implementation: scripts implement Xvfb display, XFCE watchdog, xdotool interactions (click/type/scroll/etc.), screenshots, and VNC/noVNC access. All requested behaviors are explained and present in the files.

SKILL.md and scripts stay on task (set DISPLAY, take screenshots, control mouse/keyboard, install and run VNC). However the setup script instructs the user to run a privileged installer that writes systemd unit files, copies a watchdog into /opt, and masks /usr/bin/xfdesktop — actions that are beyond simple user-space tooling and should be reviewed before running.

There is no formal package-install spec in registry metadata, but the included setup script runs apt to install dependencies and writes systemd units. Packages are installed from the distro repos and Chrome from Google's official URL (dl.google.com). No unknown third‑party download hosts or URL shorteners are used.

The skill does not request any environment variables or external credentials. Scripts set DISPLAY=:99 and use standard X11 tools. One privacy note: screenshot scripts output base64 PNGs to stdout, which can contain sensitive screen content — be mindful how those outputs are used or transmitted.

The setup script creates persistent systemd services, enables auto-start, copies scripts to /opt, and masks /usr/bin/xfdesktop (moving the original). These are persistent, privileged changes — reasonable for a persistent headless desktop but high-impact. Also the provided systemd x11vnc unit does not bind explicitly to localhost or configure authentication, so if services are started on a machine with open network access they could expose an unauthenticated VNC server unless the operator uses SSH tunnels or firewall rules.
