 "page_title": "How to preview a local Vite or Express server on your phone with Mobile Harness",
 "summary": "Run a Vite, Next.js, or Express server on the phone and test it in a sandboxed WebView.",
 "who": "A web developer who wants to check a running server's interface on mobile without deploying it.",

  "Open the Terminal and run your project's dev server command, such as the one for Vite, Next.js, or Express.",
  "Open the web preview from the workspace to load the running server.",
  "Check the console telemetry in the preview for errors, then fix the code and reload."
 ],
 "agent_prompt": "In Mobile Harness on an ARM64 Android phone, start a Vite dev server for the project at <project-name> from the Terminal and open the Instant Web Preview.
