Is there a way to set up GitHub so that comment-only changes can be submitted without review?

Question

Comments should not break any tests so the bar should be lowered to encourage more piecemeal check-ins. Does GitHub or any other code hosting platforms provide options to auto-detect the nature of the change, and adjust the number of required reviewers accordingly?

Answer 1

First, comment can break any test relying on the size or number of line of a given file.

But assuming this is not the case, you would be looking at a GitHub Action like

• pascalgn/size-label-action able to assign label to a PR (you need to modify it in order to detect not the size of the code diff, but the presence of comments only)
• actions/label-requires-reviews able to assign, for a given label, the number of approved reviews needed on the Pull Request for the action to return a success value.

Chain those two actions and you could influence that way the number of required reviewers.
