Feature request: Add intraline diff highlighting to Codex review.
Current behavior:
Codex shows changed lines in the diff, but when a long prose line is edited, the whole line appears changed. If only one word, number, or phrase was modified, it is hard to identify the exact edit.
Requested behavior:
Keep the normal line-level diff view, but also highlight the changed words, numbers, or phrases inside each changed line. This should work like intraline diff highlighting in GitHub, VS Code, or other code review tools.
Generic example:
Original: The system achieved a score of 0.80 in the final test.
New: The system achieved a score of 0.85 in the final test.
The diff should show the full line for context, but highlight only 0.80 as removed and 0.85 as added.
This is especially useful for LaTeX, Markdown, documentation, and other prose-heavy files where paragraphs are often stored as long lines.

This would be a great improvement.
Reviewing code changes in the CLI is much more sluggish than it needs to be due to the lack of a word-level diff. Viewing the changes in an IDE or using git diff doesn't work if the agent made additional changes without a commit in between.
Scenario:
Because there was no commit between the changesets, the quality of the tool output which shows the diffs is very important.
Disclosure: I’m building DiffReceipt, a small tool around AI-code review evidence.
+1 to intraline highlighting. For review, the problem is often not just “show me the changed file”, but “show me the actual decision-relevant change.”
In long prose/config lines, whole-line diffs make the review trail noisy. A receipt/review view could combine:
That would make AI-generated changes easier to inspect without forcing reviewers to reconstruct the intent from raw diffs.
