What issue are you seeing?

When reviewing changes in Codex app, Markdown (.md) files do not show the diff content.

Instead of showing line-by-line changes, it only displays a summary card like:

(+2 -1)

No diff details are visible.


What is the expected behavior?

The review panel should display the full diff (line-by-line changes) for Markdown files, same as other file types like .php.


What is actually happening?

  • .md files: only summary card shown, no diff content
  • .php files: diff works correctly and shows full changes

Steps to reproduce

  1. Open a repository in Codex
  2. Modify a .md file
  3. Open Review panel
  4. Observe that only summary (+X -Y) is shown, no diff content

Additional context

  • This issue seems specific to Markdown files
  • Other file types (e.g. .php) display diffs normally
  • git diff shows correct changes, so the issue appears to be in Codex UI/rendering

What steps can reproduce the bug?

TL;DR

The issue can likely be resolved by updating the Codex App to a version that correctly handles Markdown file diffs or by reporting the issue to the Codex development team for further investigation.

Guidance

  • Verify that the issue is specific to Markdown files by checking if other file types (e.g., .txt, .js) also exhibit the same behavior.
  • Check if there are any known issues or updates related to Markdown file diff rendering in the Codex App release notes or community forums.
  • Test the git diff command in the terminal to confirm that the diff output is correct, as mentioned in the issue.
  • Consider reporting the issue to the Codex development team with detailed reproduction steps and environment information for further assistance.

Example

No code snippet is provided as it is not directly relevant to the issue.

Notes

The issue seems to be specific to the Codex App's UI/rendering, and the root cause is unclear without further investigation. The provided information suggests that the issue might be related to how the Codex App handles Markdown files.

Recommendation

Apply workaround: Report the issue to the Codex development team for further investigation and potential resolution in a future update, as the current version (26.415.21839) does not seem to handle Markdown file diffs correctly.
