Batch-Addressing Pull Request Review Comments with GitHub Copilot Cloud Agents

This is the article for Day 19 of the Azure PoC Club - Qiita Advent Calendar 2025 - Qiita.

This post covers how to have Copilot handle fixes for "human review comments" on "human-created pull requests."

Introduction

I previously wrote this article, but it became outdated in just a few days.

I will show you how to elegantly have GitHub Copilot's cloud agent fix review comments on a pull request in its latest state.

Steps to have Coding agent fix comment contents

I added some logic haphazardly because it was a simple fix, but then I was asked for corrections in the comments!

Previously, it was necessary to open the cloud icon (agents panel) at the top of the pull request screen and enter instructions for the Coding agent...
However, now you can simply comment directly in the PR's comment section with @copilot, for example, "@copilot please apply fixes corresponding to this comment"!
Note: In this example, I'm assuming we are addressing multiple comments at once. If you want to fix comments individually, you just need to reply to the specific comment with "@copilot", so including a link to the comment is unnecessary.

Then, Copilot will create a working branch from the pull request branch, perform the work there, and open a pull request like this:

As an aside, it is great that CodeQL is now run when the Copilot cloud agent is executed.

If the contents of the draft pull request created by Copilot look good, convert it to a regular pull request and merge it. With this, the test branch has been updated to address the comments by Copilot!

If Copilot's fixes are spot on, you can finish addressing review comments without touching the code yourself. Even if fine-tuning is needed, it's convenient because you can just add your own fixes on top of the pull request created by Copilot.

If you do want to make adjustments, you can open that pull request from the GitHub extension in VS Code and check out the branch created by Copilot with a single button click.

Information for Pro and Pro+ users

Currently, Copilot Pro and Pro+ users can select the model for the Copilot cloud agent. If you want it to work with a specifically designated model, it's best to send instructions via the cloud icon in the top right, as described in my previous article.

Conclusion

The pace of change is so fast that this article might end up having a short shelf life again...
