This action can be used as a blocking status check on pull requests that contain commits that should have been auto-squashed.

- name: Check for 'amend!', 'fixup!', or 'squash!' commits
  uses: matijs/no-fixups-action@v1

This action will only run on pull requests and will fail when used on, for example, pushes. There is one input. There are no outputs.

It is not necessary to use actions/checkout first. This action takes care of that and can be used on its own. See below if you want to do the checkout yourself.

Make sure to pass the fetch-depth and ref inputs to the checkout action and let no-fixups-action know it can skip the checkout like this:

- name: Checkout
  uses: actions/checkout@v4
  with:
    fetch-depth: 0
    ref: ${{ github.event.pull_request.head.sha }}
- name: Check for 'amend!', 'fixup!', or 'squash!' commits
  uses: matijs/no-fixups-action@v1
  with:
    skip-checkout: true
