The viewer

The viewer is a local page over your project's .stuntdouble/ folder. It lists every run, local and cloud, and updates while a run is going.

Open itCopy Anchor Link

Every run prints its viewer link. To open the viewer at any other time:

/stuntdouble:open

Someone without Claude Code, such as a teammate reviewing your branch, can open it from the project folder:

npx stuntdouble view

Open the link it prints. Press Ctrl C to stop the viewer.

What it showsCopy Anchor Link

• Verdicts. Each check's result and the evidence behind it.
• Screenshots. What the actor saw at each step.
• The activity log. Every action the actor took, in order.

Stop a runCopy Anchor Link

Select Stop while a run is going. The actor stops at its next step and ends the run. Checks it already judged keep their verdicts, and /stuntdouble:run <checklist> resume picks up a stopped run later.

The portCopy Anchor Link

The viewer listens on 127.0.0.1, starting at port 4747. If that port is taken, it uses the next free one, so always use the link Studio prints.
