# This workflow sets various "skip_*" output values that can be used to
# determine what workflows/jobs are expected to be executed. Sample usage:
#
#   skipper:
#     uses: ./.github/workflows/gatekeeper-skipper.yaml
#     with:
#       commit-hash: ${{ github.event.pull_request.head.sha }}
#       target-branch: ${{ github.event.pull_request.base.ref }}
#
#   your-workflow:
#     needs: skipper
#     if: ${{ needs.skipper.outputs.skip_build != 'yes' }}
