What issue are you seeing?

Codex in VS Code keeps insisting that it is still in Plan Mode and refuses to implement the requested changes, even though Plan Mode has already been switched off in the UI.

It repeatedly says things like it is “still seeing Plan Mode” on its side, that it is “not allowed to edit files yet,” and that it will only make changes once the mode switches back to Default or implementation mode. However, from my side, the mode has already been switched back.

As a result, Codex gets stuck in a loop where it acknowledges the implementation target, restates what it plans to change, but never actually performs the edits.

What steps can reproduce the bug?

What steps can reproduce the bug?

Open VS Code with the Codex extension enabled.

Start a task that involves planning and then implementing file changes.

Let Codex produce a plan.

Switch out of Plan Mode back to Default / implementation mode in the UI.

Tell Codex to continue or confirm that the mode has been switched back.

Codex still responds as if it is in Plan Mode and refuses to edit files. (only have this bug sometimes)

What is the expected behavior?

Once Plan Mode is switched off, Codex should recognize the new mode correctly and proceed to implement the approved changes.
