Once FeatureMap has been integrated into an application, the knowledge of which files are assigned to a given feature may be used during the pull request review process. The specific implementation depends largely on the structure of a given application, but broadly you may consider the following steps:

• Inspect the files that have been modified as part of a pull request
• Use FeatureMap’s for_file public interface to retrieve feature assignment data for each of those files
• Collect and group changes to each associated feature
  • This process can be aided by the group_commits method exposed by FeatureMap
• Publish the changes back to GitHub via a label or comment on the PR
