What platform is your computer?

Darwin 25.4.0 arm64 arm

What issue are you seeing?

The summarized message shows only the diff tool view and end turns. What I find strange is that the diff tool is showing as just colored ANSI text (without a full diff background like edit-diff). The final message showed “Work for N duration” but then showed the diff and ended without any explanation. I thought my token usage was run out, but it's not.

What steps can reproduce the bug?

Uploaded thread: 019dc009-353b-7090-9e0c-10e36dd661cb

What is the expected behavior?

Codex should end the turn with a concrete, summarized message, and if the usage quota is run out, it should show a TUI message as normal.

  1. Should be related to verbose tool output; I see that the diff tool is being shown as full in the TUI transcript.
  2. Switching to GPT-5.4 and another account, still having the same issue, so this is not model- and subscription-related; it could be in the core.

I just realized another possible cause is that, because /diff is triggered without compact/condensed output, hence, in large diff sessions, the context window could be being overloaded. Hence, it could be that Codex got confused and could not trigger compaction because this is the tool's output, not conversation context => agent's run loop is confused.
