Codex Desktop advertises Browser, Computer Use, and Google Drive skills but does not inject their callable tools

What issue are you seeing?

Codex Desktop shows Browser, Computer Use, and Google Drive as installed and enabled, and their skills are advertised to the agent. However, the active task does not receive the callable action tools required to use them.

Installed plugin versions:

• Browser: 26.707.91948
• Computer Use: 1.0.1000387
• Google Drive: 11c74d6b

The Computer Use helper service is running, and the in-app browser is open. Despite this, the task cannot operate the browser or Mac UI. Google Drive/Docs actions are also absent, including native document import, Docs readback, PDF export, and Sheets updates.

This creates a contradictory state: Codex tells the agent that the skills are available, but the tools necessary to execute those skills are missing. Refreshing or reinstalling the Google Drive plugin did not update the active task’s tool surface.

This blocked a production workflow involving 40 native Google Docs. The local DOCX artifacts were already complete, but Codex could not import or QA them in Google Docs.

What steps can reproduce the bug?

1. Install and enable Browser, Computer Use, and Google Drive in Codex Desktop.
2. Open the in-app browser.
3. Start or continue a Codex task.
4. Ask Codex to use @Computer, @Browser, or @Google Drive.
5. Observe that the corresponding skills are listed as available.
6. Observe that the task does not expose the callable tools required by those skills.
7. Refresh or reinstall the affected plugin.
8. Continue the existing task and observe that its callable tool set does not refresh.

What is the expected behavior?

If a plugin and its skill are shown as installed, enabled, and available to a task, the required callable tools should also be injected into that task.

If an existing task cannot refresh its tool manifest after a plugin installation or update, Codex should display a clear message requiring the user to start a new task or restart the application.

The agent should not advertise a skill as usable when the execution surface behind that skill is absent.

Additional information

This is not an authentication or permission failure. The Google Drive actions are absent entirely rather than returning an OAuth error.

The UI currently makes this look like user error and causes agents to provide contradictory explanations. Plugin installation state, skill availability, and callable tool availability need to be presented consistently.
