The bots will automatically detect if the commit in a backport pull request is a clean backport. If it is then bots will add the label "clean" to the pull requests. Backport pull requests which commit is a clean backport can be integrated without reviewers (configurable per repository). This means that not all commit messages for backport commits will have a "Reviewed-by" line.
The Skara CLI tools features the tool git pr create for creating pull requests. The option --backport to git pr create makes the title of pull request consist of "Backport" and the given hash, for example git pr create --backport=5a526c1c5716f6d9a7fc94741bcdb2f424d342df creates a pull request with the title "Backport 5a526c1c5716f6d9a7fc94741bcdb2f424d342df". The value of --backport does not have to be a full hash, it can be an abbreviated hash or a reference.
Backport Commit Command
The /backport commit command can be used to quickly create a backport pull request for a given commit. Just navigate to the comment in source code hosting provider's web UI and add a comment consisting of "/backport <repo>". If the commit does not apply clean on the target repository then a message will be shown for the files with conflicts.
