I would like to implement a workflow like this:

1. Herald Rule for adding reviewers on new Diffs - works
2. Run a build-plan (Executes a external Jenkins Build) an reports back the results - works
3. Reviewer or Herald rule accepts the diff if the build was successful. - What kind of Herald rule is this?
4. committer runs arc land - Block if the build failed - What kind of Herald rule is this?

Is there a way to do so?
