can it read code review comments? I've been finding that having claude write code but letting codex review PRs is a productive workflow, claude code is capable of reading the feedback left in comments and is pretty good at following the advice.

I’m letting Claude Code review the code as part of a gitlab CI job. It adds inline comments (using curl and the http API, nightmare to get right as glab does not support this)

CC can also read the inline comments and creates fixes. Now thinking of adding an extra CI job that will address the review comments in a separate MR.

Have you tried GitHub Copilot? I've been trying it out directly in my PRs like you suggest. Works pretty well sometimes.

I find that ChatGPT’s Codex reviews - which can also be set up to happen automatically on all PRs - seem smarter than Copilot’s, and make fewer mistakes. But these things change fast, maybe Copilot caught up and I didn’t notice

No codex catches genuine bugs here that multiple reviewers would have overlooked, whilst copilot only comes with nitpicks. And codex does none of those, which is also great.
