| # This workflow run on the completion of the | |
| # build workflow but only does anything if the | |
| # triggering workflow uploaded an artifact. | |
| # | |
| # Do note that it is then the trigger workflow that | |
| # determines if this will update the PR text body. All | |
| # this workflow does is check if an uploaded artifact | |
| # exists and there is a PR tied to the previous workflow. | |
