What issue are you seeing?

After the latest update, Codex no longer shows enough intermediate progress while working on a task.

It now feels like a black box: it executes for a long time internally and only presents the final result, which makes it difficult to monitor what it is doing, catch mistakes early, or intervene when it starts heading in the wrong direction.

I am not asking to see the model’s internal chain of thought. I am asking for better execution transparency, such as visible progress updates, smaller checkpoints, and clearer status reporting during long-running tasks.

What steps can reproduce the bug?

1. Start a non-trivial coding task in Codex.
2. Let it work on a longer task with multiple changes.
3. Observe that Codex continues for a long time without exposing meaningful intermediate progress or checkpoints.
4. There is no practical opportunity to review its direction or intervene early.

What is the expected behavior?

Codex should provide incremental progress updates while working, including what it has completed, what it is currently doing, and what it plans to do next.

For longer tasks, it should support checkpoints or step-by-step execution so the user can review progress and intervene before too much time is spent on an incorrect approach.
