To make sure any modification you make to the Prettifier configuration is correct, make the change in a pull request. If Prettifier detects configuration changes in a pull request, it adds a review comment confirming whether they are valid. We call this GitHubOps!
Prettifier also offers bot commands to debug your setup. To try them out,
/prettifier help on an issue or pull request. Prettifier will add a
comment with a list of all available bot commands. The current commands are:
/prettifier user errorposts the error message Prettifier would print when the user provides a broken configuration
/prettifier config errorshows the error message Prettifier prints when it detects invalid configuration
