| # This action is run whenever the `pre-commit` action finishes. Because the | |
| # `pre-commit` action is an unprivileged action running on (for example) the | |
| # `pull_request` event, it's run without write permissions to the repository, so | |
| # we use a separate privileged `workflow_run` action here to pick up its results | |
| # and convert them into suggestion comments. | |
| # | |
| # This action is only run from the workflow file on the trunk branch. Changes to | |
| # this file will not take effect until they are merged to trunk. | |
