PR Chat lets developers ask context-aware questions about a specific PR to understand changes before approving. Inline code editing allows review feedback to be sent directly to Codex, with the proposed patch visible inline so reviewers can accept, edit, or reject it without leaving their current tool. ## Content Two recent Codex updates are worth knowing about if you do code review through it. ## Custom review rules via AGENTS.md You can now add a "Code Review Rules" section to your repository's `AGENTS.md` file. Codex will apply those rules during review and cite them directly on pull requests. The practical use case: whatever feedback your reviewers keep leaving on every PR, write it down once. Keep each rule concise and scoped to a specific issue so Codex can catch it reliably, even when the relevant context lives in one corner of the codebase that reviewers don't always have in their heads. ## PR Chat and inline editing Codex also now lets you review pull requests and make follow-up edits without switching tools. PR Chat lets you ask questions about a specific pull request in context. From there, you can send review feedback directly to Codex, inspect the proposed patch inline, and accept, edit, or reject it before anything gets applied. The combination means less context-switching: question, patch, review, and decision all happen in one place. ## Questions this post answers ### How do I define custom code review rules for Codex to enforce on pull requests? Add a Code Review Rules section to your repository's AGENTS.md file. Codex applies those rules during review and cites them directly on pull requests. Rules work best when kept concise and scoped to a specific issue, especially for feedback tied to context that lives in one part of the codebase reviewers might not remember. _Teams standardizing PR feedback can track new Codex review capabilities like this through daily.dev._ ### What is PR Chat in Codex and what can it do during a pull request review? PR Chat lets you ask questions about a specific pull request in context, then send review feedback directly to Codex. You can inspect the proposed patch inline and choose to accept, edit, or reject it before any change is applied, keeping question, patch, review, and decision in a single workflow without switching tools. _daily.dev helps developers adopting in-editor PR review tools stay current on Codex's evolving workflow._ ## Community discussion Top comments from developers on daily.dev. **@idoshamun** · 0 upvotes > This is great actually!! **@randy** · 0 upvotes > Now if they could add it to the GitHub integration. 😂 I don't use the Codex app, so the shiny new things are useless to me! --- Tags: [#code-review](https://daily.dev/tags/code-review), [#openai-codex](https://daily.dev/tags/openai-codex) [View this post on daily.dev](https://daily.dev/posts/codex-adds-pr-chat-and-inline-code-editing-for-pull-request-reviews-fjvh0dpgt) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Codex adds PR Chat and inline code editing for pull request reviews","url":"https://daily.dev/posts/codex-adds-pr-chat-and-inline-code-editing-for-pull-request-reviews-fjvh0dpgt","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/codex-adds-pr-chat-and-inline-code-editing-for-pull-request-reviews-fjvh0dpgt"},"datePublished":"2026-07-16T23:48:14.470Z","dateModified":"2026-09-13T19:57:49.918Z","description":"OpenAI has shipped two new Codex features targeting pull request workflows.
