Windows Computer Use enabled but node_repl/js tool is not injected into sessions

What version of the Codex App are you using?

Codex Desktop for Windows. Computer Use bundled plugin version observed in the affected session: 26.609.30741.

What platform is your computer?

Windows, native Windows workspace.

What issue are you seeing?

The bundled Computer Use plugin is installed and enabled, but the JavaScript execution tool required by the plugin is not exposed to the model session.

The Computer Use skill requires the Node REPL execution tool, typically:

mcp__node_repl__js
node_repl/js
js

However, none of these tools are present in the active session. js_reset is also absent.

The plugin itself is recognized by the session and its required bootstrap file exists:

%USERPROFILE%\.codex\plugins\cache\openai-bundled\computer-use\26.609.30741\scripts\computer-use-client.mjs

Because the execution tool is missing, the supported Computer Use bootstrap path cannot run:

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

This appears to be a plugin tool-registration or per-session tool-injection problem rather than the Computer Use plugin simply being disabled.

What steps can reproduce the bug?

1. Open Codex Desktop on Windows.
2. Enable the bundled Computer Use plugin.
3. Fully restart Codex Desktop.
4. Create a new session/thread.
5. Ask Codex to use Computer Use.
6. Observe that the Computer Use skill/plugin is available, but mcp__node_repl__js, node_repl/js, and js are not exposed.
7. Disable and re-enable the plugin, restart Codex, and create another new session.
8. The problem persists.

What is the expected behavior?

When the Computer Use plugin is enabled and its skill is loaded, the same session should receive the required Node REPL JavaScript execution tool so it can bootstrap computer-use-client.mjs and connect to the Windows Computer Use helper.

Troubleshooting already attempted

• Fully restarted Codex Desktop.
• Disabled and re-enabled the Computer Use plugin.
• Created a new session/thread.
• Confirmed that the plugin is recognized and scripts/computer-use-client.mjs exists.
• Directly inspected the current session's callable tool list and confirmed the Node REPL JavaScript tools are missing.
