Stunt Double Studio: doctor
Check that Stunt Double Studio can run locally with /stuntdouble:doctor: Node, Chrome, the viewer port and how local runs are billed.
/stuntdouble:doctor, one of the Studio skills (/stuntdouble:setup, /stuntdouble:run, /stuntdouble:open, /stuntdouble:cloud and /stuntdouble:doctor).
Call doctor() from the local server and relay its lines. Only if this session has no doctor tool, run npx -y stuntdouble@0.1.3 doctor with Bash, or ask the person to run it in a terminal where Bash is not allowed. If the local tools are missing altogether, the local server did not start: check Node 22.18 or later and npx, then /mcp. A slow first tool listing is npx starting up (about 1.5 seconds), not the server.
