    This repository has a `gorelaserConfig`: ${{ outputs.goreleaserConfigExists.exists }}.

    (Since these are just Go `text/templates` and `goreleaserConfig` was parsed as YAML we can access every field)

    The `goreleaser.yml` defines the following `before.hooks`:

    ${{ range $index, $hook := outputs.goreleaserConfig.before.hooks }}
    - `${{ $hook }}`
    ${{ end }}

    These files were added by the steps:

    ```
    ${{ join steps.added_files " " }}
    ```
