nvidia-broadcast
Use when controlling NVIDIA Broadcast through MCP to apply effects, process local media, select devices, or change camera resolution, or when Broadcast is missing or too old to expose the gateway and the user wants it installed; not for Broadcast app settings outside the MCP gateway.

What this skill does
NVIDIA Broadcast Hard rules 1. Launching: start Broadcast only by running powershell.exe -NoProfile -ExecutionPolicy Bypass -File "<skilldir>\scripts\launchbroadcast.ps1" with the terminal tool. When running inside WSL, follow Launch and version-check through interop in references/connection.md instead. Except for the security-policy fallback below and that WSL interop procedure, never invoke NVIDIA Broadcast.exe directly — not via terminal, executecode, subprocess, or Start-Process. Security-policy fallback: use this only if security policy blocks the launcher script. Confirm that NVIDIA Broadcast.exe is not already running, then run: powershell.exe -NoProfile -Command "Start-Process -FilePath ([Environment]::ExpandEnvironmentVariables('%ProgramFiles%\NVIDIA Corporation\NVIDIA Broadcast\NVIDIA Broadcast.exe')) -ArgumentList '--launch-hidden' -WindowStyle Hidden" with the terminal tool. 2. Command tools: follow Which tool to run commands with below. 3. Never read effect state from disk — not AppSetting.json, not the registry, not logs, not the UI. Those are saved settings, not live state. Exception: gateway.json may be read and decoded only to obtain the gateway port for rule 4; it is connection configuration, not effect state. 4. Connecting to the gateway — exactly these steps, no other path: 1. Before launching or registering the gateway, check the standard executable path and read its ProductVersion without launching it. If the executable is missing or its version is 2.2.x or older, stop the connection sequence and follow Installing or updating NVIDIA Broadcast. Do not return the restart-only response below. 2. Check Broadcast is running: tasklist /FI "IMAGENAME eq NVIDIA Broadcast.exe" via terminal. If Broadcast is installed but not running, launch it immediately (rule 1); do not ask the user to start it manually. A gateway.json left from an earlier run proves nothing about whether the gateway is live. 3. …
