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

Our repo is huge and need this for sure 🙇🏼

[apdev-JulienBreton]

Hey @timrogers Hi is it possible to get an update on waitlist ? My devs ask me everyday when we get access =)

thx

[baptLesta]

Hey @timrogers Do you know where my company Zeffy is on the waiting list, we are waiting for this for weeks now and we are super excited about it 😃

[DanielHC16]

Same!

[stalinyadav]

@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?
it was really nice

[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?

[christian-andersson]

got my request approved for my organisation, and we are paying customers, but code review is still not available for me, is ther anyone from github here actually reading this? there are plenty more in my situation..

[DanielHC16]

Same here

[redveronika]

the same for my organization

[JohnLBevan]

@christian-andersson , @DanielHC16 , @redveronika I had the same but found it was a mistake on my part.

Signing up to the waitlist shows you as on the waitlist; but per this ticket that's now irrelevant as the feature's generally available.

The fix for me was:

• Browse to my organisation's settings: https://github.com/organizations/MY-ORG-NAME/settings/copilot/policies
• Look at setting Copilot in GitHub.com - for me this was Disabled and greyed out... as it was managed at enterprise level. If you can edit in your org, skip the next step, otherwise do the next step for managing at enterprise level.
• Check your enterprise settings: https://github.com/enterprises/MY-ENTERPRISE-SLUG/settings/copilot?tab=policies
• On the dropdown by Copilot in GitHub.com choose Enabled
• Check the box: Opt in for access to Copilot preview features
• Now this is enabled for your org/enterprise (settings managed at enterprise level will have propogated down to your orgs without you needing to do anything). Users licensed with CoPilot will now see Copilot as a suggested reviewer for any PRs.

[christian-andersson]

@JohnLBevan for us this was not the problem, everything was setup up correctly from our side, after I filed a support ticket to Github, they went in an refreshed the copilot cache for our account, and that solved everything for us.

[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!

[williamjamir]

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.

[aspearman]

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.

[beingminimal]

@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?

[PETAPAMENMESJJ]

I like this fast advancement 💚

[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.

[bruno-viva]

@eshwer is C++ on the roadmap? This is probably the most used language on GH that didn't get support yet :'( Thanks in advance! (by the way, is the roadmap public?)

[xmatthias]

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?

[eshwer]

Good news, we've GA'd! This should be resolved now!

[dc-tonglec]

As of today, 4/21, I still cannot select Copilot as a reviewer. I could set ruleset option "Request pull request review from Copilot", but that does not kick off Copilot review.

org: TongLeC
user: dc-tonglec

[eshwer]

hi @dc-tonglec - what Copilot license do you have?

Copilot code reviews is only available to Copilot Pro, Pro Plus, Business and Enterprise users... in other words, it's not available to free users. Could this be the case?

[dc-tonglec]

I believe I am an Enterprise user, as my organization "is billed at the enterprise level". How to double check it?

[eshwer]

Do you mind filing a support ticket with your information?

[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.

[eshwer]

What are some examples of how you'd want to use it?

[HotCakeX]

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#.

[eshwer]

Thanks for this example, we will use it in our testing!

[wadamczyk-insolutions]

I second the question by @maciejbrzezinski - are there any plans for PHP support?

[eshwer]

In public preview: https://github.blog/changelog/2025-05-07-copilot-code-review-now-supports-all-languages-in-public-preview/

[Yuri05]

Is it planned to support the R language?

[wreiske]

Any plans for GitHub Enterprise Server (GHES) support? We would love to be able to use Copilot reviews with our on-prem instance of GitHub.

[iamnolimit]

Currently, GitHub Copilot—including features like Copilot Reviews—is not yet natively supported on GitHub Enterprise Server (GHES). Copilot relies on GitHub.com's cloud-based services to power its AI features, which means it's not compatible with fully on-prem or air-gapped GHES environments at this time.
That said, GitHub is actively exploring ways to bring Copilot capabilities to GHES in the future. Feedback from enterprise users like you is extremely valuable and helps shape product priorities.
In the meantime:

1. You can still use GitHub Copilot in supported IDEs (such as VS Code or JetBrains), even if your repositories are hosted on GHES, as long as the IDE has access to GitHub.com.
2. If cloud hosting is an option for your organization, GitHub Enterprise Cloud (GHEC) offers full Copilot integration, including AI-powered code reviews and chat.

[doggy8088]

Copilot Code Review seems unable to obey github.copilot.chat.localeOverride settings. No matter I do, it can only response in English. Is that a bug?

[SwuduSusuwu]

Around 2 years ago had started to produce the base class for a neural network with the goal to input all of GitHub's public repositories + Wikipedia.org's articles + StackOverflow's questions&answers as training data (with commit messages as the input, and the source code diffs as the output).
It sounds as if this is what GitHub Copilot does now? Have tried to use Copilot, but it often links to documents which show "404" or "Page not found", and suggests code with functions which are not found. Assistants from other businesses also have such issues.

• Suggestion: improve Copilot with some sort of hard-coded test such that if resources (such as documents) and functions (such as API calls for popular software packages) are no longer found, it says when those were last found (and perhaps exclude if those are not found now and there is no record that those were ever found).
  • Since network access costs a lot (versus local compute), cache the existence test results (if the resources were found within the last month, it is senseless to re-fetch those). For instance, a simple table whose columns are the Uniform Resource Identifier, Unix timestamp, and bool "found", with 1 row per resource. This should use few resources.
• Acknowledgement: Copilot has given suggestions which had use. It is just difficult since most of the resources are not found and the sole purpose to ask Copilot to suggest functions is when it is not feasible to install the packages (such as Tensorflow) on the local development environment (such as this smartphone), with the result that development continues without knowledge that the underlying API in use does not exist.

[SwuduSusuwu]

Examples of issues on GitHub Copilot:

• Documentation: The TensorFlow C++ API is less documented than Python. Sometimes, you’ll have to look at the source or Python docs and map concepts over.

  • 404
    Sorry, we couldn't find that page.

• For most binary classification, use SigmoidCrossEntropyWithLogits. For multi-class, use SoftmaxCrossEntropyWithLogits.

  • There is no C++ SigmoidCrossEntropyWithLogits. Not on TensorFlow's C++ function list, nor Google's search results (but Copilot suggests this function in a C++ commit review).

[SwuduSusuwu]

Example of issue on Anthropic's Grok-2:

• 
  • tensorflow::LoadSessionFromSavedModel is not found TensorFlow's C++ function list, nor Google's search results.

[scriptori]

Is it available for Eclipse IDE?

[albal]

When you are using GitHub Copilot paid version and you have exceeded the maximum number of request for the month, Copilot free is no longer available for PR reviews. I think the option is free should be available even if you have exceeded you limits in the paid version.

[SwuduSusuwu]

1-plus this.
If GitHub has serious CPU load issues, just set the priority of users who have exceeded their quota to "lowest" (so that code review stops until GitHub has idle / background resources to do those reviews).
The reason is that code review gives significant value to the public and thus is important to have access to.

[pratt33k]

Is there a way to add automatic code review if I have copilot pro but other authors who raised the PR don't? @eshwer @Akash1134
This would be so helpful

[SwuduSusuwu]

https://github.com/marketplace?type=actions&category=code-review lists scripts which use computer assistants (such as GitHub's Copilot, or other Generative Pretrained Transformers) to do automatic PR reviews.

[eshwer]

No, sorry not at this time.

[MaryGao]

Is it possible to show loggings for every time reviewing? I found Copilot would miss some review comments and I don't know how to debug to adjust my instructions?

[eshwer]

Copilot code review shows up in the Audit logs for a PR today

[MaryGao]

We would put some links under .github/copilot-instructions.md, can Github Copilot code review read the content of the links?

[trietbui-zalora]

I try to update the code review guidelines in github/copilot-instructions.md but it seems only work on locally (IDE) but not in Github PR web.

[MaryGao]

Yes, I have the same feeling. The local experience is more stable than web RP but I don't know why.

[eshwer]

I don't believe we can follow links at this time.

[MaryGao]

We would put some links under .github/copilot-instructions.md, can Github Copilot code review read the content of the links?

[iamsuneeth]

Could we reference markdown files in the same repo in copilot instructions ?
for example the below instruction will work or not ?

When reviewing pull requests, Copilot should:
- refer coding standards documents present in the `docs/standards/` folder.

[eshwer]

This won't work today reliably, but is on our roadmap to improve!

[danquirk]

How do I customize GitHub Copilot code review for multiple repos or an entire organization? I don't want to have to copy/paste custom instructions into copilot-instructions.md for every repo and periodically update them as we refine new versions of common custom instructions. Is there no organizational configuration or inheritance mechanism?

[eshwer]

Support for organization instructions is on our roadmap!
