Computer Use plugin fails on Windows due to @oai/sky package subpath not exported

Summary

The bundled Computer Use plugin fails during its documented bootstrap on Windows before sky.list_apps() can run. The failure is a Node package exports error from the bundled @oai/sky runtime.

Environment

  • OS: Windows NT 10.0.26200.0
  • PowerShell: 7.5.5
  • .NET runtime visible to PowerShell: 9.0.14
  • Codex bundled plugin: openai-bundled/computer-use version 26.611.61753
  • Bundled @oai/sky runtime observed: 0.4.13
  • A second local cua_node runtime with @oai/sky 0.4.10 shows the same package exports shape

Reproduction

Using the plugin-documented bootstrap:

const { setupComputerUseRuntime } = await import("<plugin-root>/scripts/computer-use-client.mjs");
await setupComputerUseRuntime({ globals: globalThis });
globalThis.apps = await sky.list_apps();

Actual result

Bootstrap fails immediately with:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js' is not defined by "exports" in <cua_node-runtime>/bin/node_modules/@oai/sky/package.json

The stack starts at Node ESM resolution / package exports resolution before any Windows helper call is made.

Local findings

The plugin file imports an internal subpath directly:

import { WindowsComputerUseClientBase } from "@oai/sky/dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js";

The bundled @oai/sky/package.json contains only:

"exports": {
  ".": "./dist/project/cua/sky_js/src/index.js"
}

The target file does exist on disk at:

@oai/sky/dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js

So this appears to be an export-map/package-boundary mismatch rather than a missing compiled file.

There is also a nearby bundled file:

@oai/sky/dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client.js

which imports ./computer_use_client_base.js relatively and exports WindowsComputerUseClient. That may be the intended public or package-internal entry point, but it is also not exported through package.json today.

Expected result

The documented Computer Use bootstrap should complete successfully on Windows and allow sky.list_apps() to return a list of apps/windows.

Suggested fix direction

Either:

  1. Export the required Windows internal entry point(s) from @oai/sky/package.json, or
  2. Change computer-use-client.mjs to import from a supported public @oai/sky entry point, or
  3. Bundle the required Windows client base code inside the plugin so it does not cross the @oai/sky package exports boundary.

I can reproduce this on the current Microsoft Store Codex package after self-update:

  • Codex package: OpenAI.Codex_26.611.8273.0_x64__2p2nqsd0c76g0
  • Computer Use plugin: openai-bundled/computer-use/26.611.61753
  • CUA runtime: cua_node/a89897d3d9baa117
  • @oai/sky: 0.4.13

The failure is the same ERR_PACKAGE_PATH_NOT_EXPORTED for:

./dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js

This also appears in the installed Store package payload, not only my extracted cache, so a normal Repair/Reinstall would likely restore the same broken pairing.

As a diagnostic workaround only, I backed up the runtime @oai/sky package.json and added this export:

"./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 resetting the JS kernel, sky.list_apps() returned 40 apps and Computer Use could control Windows apps (Explorer, Calculator, System Information). The workaround proves the import/export mismatch, but I do not want to keep running a patched Codex because app/plugin self-updates may overwrite it or create other issues.

I can reproduce the same Computer Use bootstrap failure on Windows after updating Codex and restarting the app.

Environment from this machine:

  • OS: Windows
  • Codex Windows app package: OpenAI.Codex_26.611.8604.0_x64__2p2nqsd0c76g0
  • Computer Use plugin: openai-bundled/computer-use version 26.611.62324
  • @oai/sky runtime version: 0.4.13
  • @oai/sky runtime path: C:\Users\fioei\AppData\Local\OpenAI\Codex\runtimes\cua_node\a89897d3d9baa117\bin\node_modules\@oai\sky
  • Computer Use plugin path: C:\Users\fioei\.codex\plugins\cache\openai-bundled\computer-use\26.611.62324

Exact error:

Package subpath './dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js' is not defined by "exports" in C:\Users\fioei\AppData\Local\OpenAI\Codex\runtimes\cua_node\a89897d3d9baa117\bin\node_modules\@oai\sky\package.json

Additional local findings:

  • The target file exists on disk at ...\@oai\sky\dist\project\cua\sky_js\src\targets\windows\internal\computer_use_client_base.js.
  • Importing that file by absolute file:// URL succeeds and exposes WindowsComputerUseClientBase.
  • The bundled @oai/sky/package.json only exports .:
"exports": {
  ".": "./dist/project/cua/sky_js/src/index.js"
}

So this still appears to be a package export-map mismatch: the file is present, but the first-party Computer Use plugin imports it through a package subpath that Node refuses.

I also observed that, in this failing thread, the JS runtime did not expose the privileged native pipe fields Computer Use expects (nodeRepl.nativePipe was absent and SKY_CUA_NATIVE_PIPE_DIRECTORY was not present), but the package-export failure happens first, before any Windows helper/native-pipe call can run.

I can confirm the same issue on Windows.

Computer Use is available as a bundled plugin, but it fails during initialization before it can connect to the desktop or run sky.list_apps().

Environment observed here:

  • OS: Windows
  • Computer Use plugin: openai-bundled/computer-use version 26.611.62324
  • CUA runtime: cua_node/a89897d3d9baa117
  • Runtime path includes @oai/sky

Exact failure:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: 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\a89897d3d9baa117\bin\node_modules\@oai\sky\package.json

I’m seeing the same issue on Windows.

Computer Use is unavailable in Codex settings, and the documented bootstrap fails before sky.list_apps() with the same @oai/sky package exports error:

Package subpath './dist/project/cua/sky_js/src/targets/windows/internal/computer_use_client_base.js' is not defined by "exports" in ...\@oai\sky\package.json

I also reported this through in-app feedback with Feedback ID:
019ed340-09f1-7783-b40b-b3f08f9c4147

Browser tools still work for me: in-app browser and Chrome control can open pages and take screenshots. The failure appears isolated to Computer Use.
