GitHub Copilot code review in GitHub.com (public preview)

[Akash1134]

Say hello 👋 to GitHub Copilot Code Review—your new AI-powered buddy that gives you quick, actionable feedback right in your favorite coding environments!

Imagine breezing through your code, knowing you have a smart assistant ready to provide insights at a moment's notice. With the GitHub Copilot Chat extension (v0.22 or later), you can now request fast, AI-driven code reviews directly in Visual Studio Code and on GitHub.com.

That's not it! Copilot can also review your code in Visual Studio Code before you push; see the changelog for more details.

Why You’ll Love Copilot Code Review:

• ✨ Quick Feedback, No Waiting ⚡ : Just highlight your code in VS Code and ask for an initial review. Copilot will give you instant suggestions that you can apply with just one click—no more endless waiting for peer reviews!
• ✨ Two Review Types:
  • Review Selection: Want a quick glance? Select your code in VS Code, run the GitHub Copilot: Review and Comment command, and let Copilot do the magic. You’ll get comments directly in your editor, making it easier to see what’s working and what could be improved.
  • Review Changes: For those deeper dives, request a review on your pull request on GitHub.com or in the “Source Control” tab in VS Code.

You are one step away from the magic 🪄 – Just join our waitlist to access this feature!

How can I get access for this feature? Already applied to waitlist 🤞🏼

Our repo is huge and need this for sure 🙇🏼

Thanks Tim! I shall be giving it a good workout in the next few weeks, is this thread where you want feedback or where is the best place?

[timrogers]

Here is great! ❤️ Thanks.

[frkhol]

Hey @timrogers ! Any chance we could get early access too (on waitlist)? Our team would love to try this out.. 😊🙏

[timrogers]

@frkhol Sure! Would you be able to email me at the @github.com email address on my profile? I'd just like to get connected with one of your company administrators before we turn it on.

[makskustomer]

@timrogers Ive been signed up for waitlist since day 1 and our org uses copilot and heavily is looking to adopt AI everywhere and to improve code quality. We are also involved in alot of other feature requests, I see the public preview options to enable this but it doesnt seem to work. Is there a feature flag that just needs to be toggled?

[alazreq]

Does help find the error in line 5?

[fnesveda]

Hey! When you sign up for the waitlist and get approved, is Copilot Code review available for your whole organization, or just for your individual account? And if only the individual account, is it possible to sign up the whole organization to the waitlist?

[timrogers]

If you're a Copilot Individual subscriber (just paying for yourself), Copilot code review would just become available to you as an individual. If you're a Copilot Business or Enterprise user, then you'll nominate an organization, and we'll onboard that whole organization.

[makskustomer]

I see the public preview right now but cant seem to turn it on despite having all the options on and all the required users licensed on github.com

[malytskyybabtec]

this is very cool and could be a serious performance booster within our enterprise subscription on many levels! My am really excited about the quality of reviews in my tests 👍 These things we need to roll out deep integration into our processes:

• please add support for Visual Studio plugin
• please add integration into AzureDevOps services

Thank you!

Regarding VS Code:

• This is the most essential feature for me. I want to receive comments and suggestions locally before I open a pull request.
• Within VS code, I tried using the "Copilot Code Review" button on the source control tab, but it usually gives "no suggestions to give" for the 17 files I've changed.
• If I execute multiple times (to overcome the previous issue), I can get comments, but they are always on the latest file I've opened (in the staged files).
• However, if I go into some of these files, select the whole code, and click "Review using Copilot," I receive at least five comments.

As a suggestion and future improvements for the VS Code:

• Please add a function to analyze code that has already been committed or pushed, allowing it to "analyze everything between HEAD and some branch."

Regarding the UI:

• I still need to assign the Copilot user to my pull request, but I likely won't, as I anticipate too much unnecessary noise.
• My excitation is about noise comments and having to delete them manually in case they are irrelevant.

Suggestion for UI:

• It would be perfect if the "Chat with Copilot" had some "shortcuts" or "default prompts" for code review, code simplification, and so on available straight as comments on the chat rather than comments on the PR directly.

It looks like it doesn’t support reviewing my *.swift files, so I can’t use it for my indie iOS app PRs. Is that right?

[aspearman]

Docs here show swift isn't supported. Supported langs:

C#, Go, Java, JavaScript, Markdown, Python, Ruby, TypeScript

Definitely would like wider language support! The indie app community in particular is big. Swift and Kotlin support would be great.

@Akash1134 We follow trunk based development and so we don't create PRs. So we would like to have code review suggestions based on staged commit before we push code to repo.
And also code review comments in respect of the whole repo code in the main branch also.
Is this already supported?

[maciejbrzezinski]

Is there a timeframe for when Dart and PHP will be supported?

[rymnc]

wen Rust?

[magnesj]

I would like to have this feature for C++. When can we expect C++ to be supported?

It would be useful to have a roadmap for planned language support.

Overall, i found the review to be okish, and it did highlight a point i didn't consider before.

Now the problem is - it finds this in one occurance, but that same file had the same exact access problem twice - which copilot somehow overlooked.
Were i not reviewing my own PR and knowing what i'm doing (or rely on copilot too much) - this would mean i'll be missing a key problem.

---

I also find the review comment of "Evaluated as low risk" a bit odd - not necessarily the comment, but that it suggests that it skipped review of these files completely.
This may be fine for a .md file (it's documentation after all) - maybe even for tests (tests can still contain slight bugs causing test flakyness).

But in my case, it skipped 2 key (key, as in important / central to the project) .py files with "Evaluated as low risk" - skipping review completely.
I suspect the files are too big for copilot to review (both skipped files are over 1000 lines) - but that shouldn't mean they're "low risk" - rather "high risk but context window exceeded".
Being honest here (couldn't analyze) would be WAY better than "Evaluated as low risk" - which is either a false errormessage - or a completely failed "risk analysis".

[talkingtoaj]

I received the email saying I have been granted access to "GitHub Copilot code review", but for my projects Copilot does not appear as a reviewer option on my Pull requests, nor as an option on rulesets for automatic review.

Did the email perhaps skip a step about something I needed to first do to activate Copilot code reviewer?

[cookieopjax]

In VS Code, I have made changes to many files, but I only ever receive suggestions for one file's modifications.

[ffxsam]

It would be nice to see the review guidelines feature open to all paid users, not just Enterprise. This is the feature we were looking forward to the most.

Hello,
GitHub Copilot Code review suggests old code and it doesn't recognize new syntax. I provided an example below. I think the data set it was trained on is old? It's like it has no idea about existence of .NET 8/.NET 9

For instance, it thinks this code which is mine, is not correct

[.. ids.Select(id => id.ToLowerInvariant())]

and instead tells me to use this

ids.Select(id => id.ToLowerInvariant()).ToArray();

but the syntax i used is totally correct and has been available for over a year in .NET/C#.

Hi,

It appears Copilot Code Review does not use https://github.com/github-linguist/linguist thus is very strict on the files it can review.

• https://github.com/github-linguist/linguist/blob/main/lib/linguist/languages.yml

Is there a way to tell Copilot Code Review about markdown-based files not having .md extension? Basically, do what linguist does but manually as a workaround.

[MalteEbner]

Is there any possibility to see our place in the waitlist? Our organisation, lightly-ai, has been on the waitlist for over a month without getting any updates.

[makskustomer]

Same here!
