• IDE context could not be enabled. Open this project in VS Code or Cursor with the Codex extension active.

What steps can reproduce the bug?

  • Open a project in VScode
  • Open Codex vscode extension and verify that the "IDE context" is working fine
  • Open Codex CLI insde a vscode terminal
  • Run slash command /ide
  • Error: IDE context could not be enabled. Open this project in VS Code or Cursor with the Codex extension active.

Code CLI cannot see which file and text I am editing/selecting in vscode to add to the context automatically. Codex vscode extension "IDE context" is working fine.

What is the expected behavior?

Both Codex CLI and Codex vscode extension should see which file and text I am editing/selecting in vscode and add to the context automatically.
