Computer Use Windows

Computer Use Windows

Use this skill when the user asks you to operate a Windows desktop application and no safer structured integration is available.

Initialize once per Anybox session

Use the Anybox js Node REPL tool. Resolve this installed skill's plugin root from the absolute SKILL.md path shown in the skill catalog, then import scripts/computer-use-client.mjs by absolute path:

if (!globalThis.sky) {
  const { setupComputerUseRuntime } = await import(
    "<absolute-plugin-root>/scripts/computer-use-client.mjs"
  );
  await setupComputerUseRuntime({ globals: globalThis });
}
return { ready: Boolean(globalThis.sky), target: globalThis.sky?.target };

Do not spawn the native helper, open its named pipe, or implement another protocol client. Importing the plugin client is the only supported initialization path; it owns the Computer Use runtime and helper lifecycle.

The Node kernel persists only within the current Anybox session. A new session or js_reset terminates the old process, so run this initialization again whenever globalThis.sky is absent.

Node REPL output contract

The js tool executes submitted code as an async function body. It does not echo the final expression like an interactive console. A bare expression such as await sky.list_apps() still runs, but its tool result is null unless the code explicitly returns or writes the value.

Always use return for any value the model must inspect. Keep reusable handles on globalThis so later calls retain the exact Window objects:

globalThis.computerUseApps = await sky.list_apps();
return globalThis.computerUseApps;

Prefer return over nodeRepl.write(...) for structured results. If a call is intentionally side-effect-only, still return a short verification object instead of relying on an empty result.

Operating loop

Keep the sky object and returned Window objects in the current session's persistent REPL. Never expect those handles to survive a session change or hard reset.
