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

Our repo is huge and need this for sure 🙇🏼

https://github.com/heyxyz/hey

[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?

[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 😃

[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

[tallior]

same here. any success in getting it to work @makskustomer ?

[makskustomer]

I now have access after todays announcement.

[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.

[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?

[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.

[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?

[tallior]

did u get it to work? same here @talkingtoaj

[unicron]

Same here. I am on a Github Business plan and have "opt in to preview features" policy enabled.

[mjfpalmer]

Same here. GitHub Business. Received the email saying the organisation had been granted access. "Opt in to preview features" ticked. Rulesets set to "Request pull request review from Copilot". Copilot not auto-added to PRs, no Copilot option in reviewers selection on PRs.

[nnellanspdl]

Adding my name to the list here.

Copilot licenses in place, received the email for "you've been granted access to Code Review", and our Organization has enabled "opt-in to preview features".

Yet, I am unable to add Copilot as a PR Reviewer.

What else is required?

cc: @timrogers

[dnorth98]

+1. Our org was accepted. In the enterprise console, I've enabled preview features for github.com for copilot but we don't see copilot as a reviewer in the drop down. Is there perhaps a delay in setting the policy in the enterprise console/org and copilot being chooseable as a 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.

[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#.

[tallior]

I got the "You’ve been granted access to GitHub Copilot code review" email today, but i can't tag copilot as a reviewer (on the website).
Anyone else experienced this? what could be wrong ?

[MarkWesBrincr]

An administrator needs to opt in to the use of public preview features in the 'Copilot > policies' settings. https://docs.github.com/en/copilot/managing-copilot/managing-github-copilot-in-your-organization/managing-policies-for-copilot-in-your-organization#enabling-copilot-features-in-your-organization

I just enabled this but I still do not see Copilot as a reviewer in my pull requests.

[mjfpalmer]

Same here. GitHub Business. Received the email saying the organisation had been granted access. "Opt in to preview features" ticked. Rulesets set to "Request pull request review from Copilot". Copilot not auto-added to PRs, no Copilot option in reviewers selection on PRs.

【Question】About Japanese localization of Copilot Code Review on VS Code"

Question Content
When using the Copilot Code Review feature in VS Code, if you specify in the custom instructions .github/custom-instructions.md to provide feedback in Japanese, will it affect the feedback provision rate, accuracy, etc.?
Also, is there any plan to support Japanese in the future?

When performing a code review using Copilot Code Review on the selected range in the VS Code editor, if you instruct to respond in Japanese in the custom instructions, compared to when nothing is specified (English), there are many occurrences of "feedback not being provided," and we believe that the instruction to respond in Japanese is affecting this.

Currently, the content of the custom instructions is as follows, instructing to respond in Japanese.
.github/custom-instructions.md

Please respond in Japanese.

[trietbui-zalora]

I'm also in the waiting list for month, but still not receive the approval yet. So sad. I'm eager to try Copilot code review.

[adrian-enspired]

How can I completely and permanently DISABLE ALL copilot-related features and usage (including removing my code/repos, whether public or not, from its training/suggestinos)?

[akaTJ]

I just received the confirmation mail from you Your organization has been granted access to GitHub Copilot code review 🤩

Unfortunately, the feature is not visible to my org. I cannot add Copilot as a reviewer, nor can I mange any settings or policies about this feature. Can someone help me out how to enable this correctly?

I was able to create a repository ruleset and I do see the code review preview feature there.

Unfortunately, I am not seeing this rule doing anything when creating new PRs.
I'm also unable to see copilot as a reviewer or manually add copilot as a reviewer to new or existing PRs.

This morning I looked at my ruleset and that last checkbox "Request pull request review from Copilot (Preview)" is gone now without any other changes on my end. It no longer shows up 🤷

[ChrisWiles]

So, can everyone add custom instructions for the review, or is it only for enterprise users?

[trietbui-zalora]

Yeah, I was really disappointed when seeing that requires Github Copilot Enterprise. :(

[jcleigh]

When I enabled an org-wide branch ruleset to enable Copilot reviews automatically, we immediately ran into issues with the Update Branch button erroring for "Changes must be made through a pull request". Is there a way to have both the Update Branch button function and automatic Copilot reviews?

[sontixyou]

Hi, I have a feedback.

Copilot review comment style

Issue

I have to read all the way to the end of the review comments from Copilot to know if there are any pointers

Improvement

I would like to see an icon like ✅️ in the review comments from Copilot. This way, it would be easy to understand and developers would know that there is no point to be pointed out.

[AlekSi]

Briefly, today there was an option to hide the old review as outdated, to avoid adding a lot of similar large comments to PR:

But now it seems that Copilot leaves reviews that are not collapsible. Would it be possible to hide/collapse them?

[AlekSi]

Ah, I guess it depends on whether I send a PR from another branch in the same repo vs. from my fork (even if I have all permissions in the upstream repo). This is a bit weird, though. Why can't I hide comments if I have permissions?

[makskustomer]

Excited to have this on, inital 24 hrs has been good. The lack of guidelines is going to seriously limit the functionality here though. How are we able to track the analytics of what this catches for us; acceptance rate, low risk findings etc.,

[tanabee]

I tried out Copilot Review, and I think it’s an amazing feature that can greatly boost team productivity! Currently, it seems to generate review comments in English—are you considering adding support for other languages?

[tanabee]

Is there a way to register Copilot as a reviewer from GitHub Actions?

[marcolenzo]

Finally, I was able to test the feature I was really looking for. Till now all looks good and I'll provide more details as I move along.

However, there were already scenarios where the review process seemed stuck and never completed. I think getting some feedback / info on the status / progress of the review would help (something similar to GitHub Actions progress)

[sftwr-ngnr]

So far I like the feature :)
But: When I create a draft PR, Copilot will not review it. Only when the PR is marked ready for review. As I think having a PR cleaned and processed even before marking it ready is way more valuable than bother others (humans) too early (in our case, this will happen due to the code owners settings). It is a machine that reviews, it doesn't care if it is on a non-ready PR or not. But it matters for the human reviewers to keep noise low. Any chance to enable it in draft PRs?
