            Hey There! and thank you for opening this pull request! 📝👋🏼

            We require pull request titles to follow the [Conventional Commits Spec](https://www.conventionalcommits.org/en/v1.0.0/) and it looks like your proposed title needs to be adjusted.

            Details:

            ```
            ${{ steps.lint_pr_title.outputs.error_message }}
            ```

      - if: ${{ steps.lint_pr_title.outputs.error_message == null && steps.check_activity.outputs.is_new == 'false' && steps.count_prs.outputs.pr_count < 2}}
