## Why it is here

OpenAI's 2:22 product film for code review in Codex: pull requests, review feedback and private conversations about code in one place; the description says GitHub code review is generally available, with GitLab support in preview. No timeline entry yet.

## Description (written by Gemini from the video)

**Summary**  
Craig Dennis from Developer Experience at OpenAI introduces Codex Code Review, a centralized workflow tool designed to remove pull request review bottlenecks. He demonstrates the interface and core features, including multi-repository PR inbox management, automated cloud and local code reviews, custom review instructions, and an interactive PR chat powered by GPT-6.1 Sol.

**What is shown**  
* **Inbox & Navigation [00:23]**: The Codex Code Review interface displays a unified inbox for GitHub pull requests categorized by "Authored by me", "Needs my review", and "Needs my team's review", along with the ability to pin active PRs to the sidebar.
* **Automated Cloud Review Summary [00:41]**: Codex's automated review summary and inline code comments (`P1` priority issues, suggested TypeScript error handling/cleanup) directly embedded beside code diffs (`index.ts`, `app.ts`).
* **PR-Specific Chat & Voice Dictation [01:00]**: Craig uses voice dictation to send a prompt to GPT-6.1 Sol Medium: *"Summarize this change and explain the risks for this project."* The model fetches repository files and generates a summary and risk analysis.
* **Review Instructions Customization [01:19]**: Demonstration of custom review guidelines (e.g., prioritizing README accuracy and requesting risk analyses across all repositories).
* **Local Private Review & Comment Drafting [01:31]**: Initiating a local review separate from the cloud review, prompting Codex to *"Ask questions and draft a comment in our team's review style"*, and preparing inline draft review comments against the diff.
* **Author View & Asset Generation [01:54]**: Viewing feedback on an authored PR (*"Add looping bicep flex laser animation"*), displaying generated output GIFs, and replying to review threads within Codex.

**Claims & numbers**  
* The presenter states that code review has become "the new bottleneck" due to the volume of AI-generated code being written across repositories [00:13].
* The presenter claims automated cloud reviews run automatically on pull requests once repository permissions are granted [00:44].
* The presenter states that GitHub code review in Codex is generally available, while GitLab support is currently in preview [02:11].

**Notable quotes**  
* "Code review is the new bottleneck. And that's why Codex now brings that workflow into one place." [00:18]  
* "Each pull request has a private chat... All my skills and connectors can be brought into this context, like our team's review guidelines or design documents or whatever." [01:01]  
* "GitHub code review is generally available, with GitLab support in preview." [02:11]

**Assessment**  
This is an official OpenAI product demonstration showcasing real user interface interactions, voice dictation, and model responses in Codex Code Review. The video is smoothly edited for demonstration pacing, showing realistic pull request diffs, automated inline comments, and interactive workflows without hidden cuts during core UI actions.
