What issue are you seeing?

In the current Codex app UI, using the “For coding” view, the agent’s action log is now collapsed into aggregate summaries such as:

Edited 3 files, explored 2 files, 2 searches

Ran 2 commands

This appears to be a recent regression. Previously, Codex showed the files that were edited by default. Now even the names of edited files are hidden unless I click into the summary.

This makes it harder to supervise the agent live, audit what it changed, and quickly decide whether intervention is needed.

I am not asking for every explored file or every search to be expanded by default. Those can reasonably remain summarized. The main regression is that the UI now hides information that is essential for coding review: which files were edited and which commands were run.

Why this matters

For coding workflows, the minimum useful information is not just “N files edited”; it is which files were edited.

Commands run are also important and should be visible by default because:

1. Commands can modify repository or system state, even when no file edit is shown directly.
2. Commands are a key signal of how the agent validated its work, for example by running tests, linters, formatters, type checks, build commands, or ad hoc inspection commands.

Hiding edited files and commands behind extra clicks creates review friction and makes the agent less inspectable. In a coding agent UI, these are not secondary details; they are core audit information.

This is not asking for all command output, diffs, explored files, or search results to be expanded. The request is only that the thread show the edited file paths and command invocations by default.

Expected behavior

In “For coding” mode, Codex should continue to show edited file names and command invocations directly in the thread by default, as it previously did, e.g.:

• Edited src/foo.ts
• Edited src/bar.test.ts
• Ran npm test
• Ran npm run lint

The aggregate summary can still exist, but it should not hide the edited-file list or the commands run in coding-focused mode.

Actual behavior

The thread now shows only an aggregate summary such as:

Edited 3 files, explored 2 files, 2 searches

To see the actual edited files or commands, I have to click into the summary.

Non-goals

I am not requesting that Codex expand every explored file, every search, full command output, or full diff by default.

Those can remain collapsed or summarized. The specific request is that edited file paths and command invocations remain visible without extra clicks in “For coding” mode.

Related but not exact duplicates

• #16415 asks for an always-expand-all inspection mode, but this issue is narrower: edited file names and command invocations should be visible by default, even without expanding everything.
• #19260 is about command/tool output folding. This issue is not primarily about expanding command _output_; it is about showing the command invocations themselves.
• #18478 is related to review UX around diff visibility, but not specifically this action-log regression.

What steps can reproduce the bug?

This happens in any Codex session in which the agent modifies code or runs commands.
