I have turned off the automatic Copilot review on the ruby repository. If you still want a review from Copilot on a specific pull request, you can get one by assigning Copilot as a reviewer. Note that this does not cover every case. A review can still be requested depending on the contributor's own Copilot configuration, or on the settings of the organization that provides them with Copilot. We cannot control either of those from the ruby org side. There are also reports of reviews firing even when everything is turned off, so a problem on the GitHub side is possible. Also, once Copilot is assigned as a reviewer, there is no setting to suppress the comment it posts. This includes comments stating it has nothing to add or that the quota has been reached. Please filter those emails on your side. If you want this changed, the request needs to go to GitHub, so please send them your feedback directly.
