What issue are you seeing?

Computer Use fails to initialize on Windows because the bundled computer-use-client.mjs imports an internal @oai/sky subpath that is not exported by @oai/sky/package.json.

Full error message:

Package subpath './dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js'
is not defined by "exports" in
C:\Users\<USER>\AppData\Local\OpenAI\Codex\runtimes\cua_node\<RUNTIME_ID>\bin\node_modules\@oai\sky\package.json
The failing import in the bundled Computer Use client is:
import { WindowsComputerUseClientBase } from "@oai/sky/dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js";
The target file exists on disk, but the original package.json only exports the root entrypoint:
"exports": {
  ".": "./dist/project/cua/sky_js/src/index.js"
}
Because Node enforces package exports, the internal subpath import is rejected before Computer Use can start. The failure happens during bootstrap, before sky.list_apps() runs.
Expected behavior: Computer Use should initialize successfully and return available Windows apps/windows.
Locally verified workaround: adding this subpath to package.json fixes the issue:
"exports": {
  ".": "./dist/project/cua/sky_js/src/index.js",
  "./dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js": "./dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js"
}
After applying that workaround and resetting the JS session, sky.list_apps() succeeded and returned 40 apps/windows.

What steps can reproduce the bug?

1. Open Codex Desktop on Windows with the Computer Use plugin installed.
2. In a thread with Node REPL available, run the Computer Use bootstrap:

if (!globalThis.sky) {
  const { setupComputerUseRuntime } = await import(String.raw`C:\Users\<USER>\.codex\plugins\cache\openai-bundled\computer-use\26.609.71450\scripts\computer-use-client.mjs`);
  await setupComputerUseRuntime({ globals: globalThis });
}

globalThis.apps = await sky.list_apps();
Computer Use fails during import with:
Package subpath './dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js'
is not defined by "exports" in
C:\Users\<USER>\AppData\Local\OpenAI\Codex\runtimes\cua_node\<RUNTIME_ID>\bin\node_modules\@oai\sky\package.json
Expected: sky.list_apps() returns available Windows apps/windows.
Session ID / token usage / context-window usage: not visible to me in Codex Desktop. Please use the attached/uploaded session if available.
