This action is an incredibly lightweight reusable workflow to validate that all Git LFS files registered in your repository's .gitattributes configuration are actually LFS pointers. This can catch scenarios where a user adds a raw binary file into the git history, eliminating the benefits of LFS for those files and causing warnings/errors for users with LFS enabled.

This action is literally just a wrapper around the following steps:

1. Check out the repository
   • Also, don't actually download LFS file contents, since we're just validating the LFS pointers
2. Run git lfs fsck --pointers to validate all registered files are actually LFS pointers

Add to a workflow in your repository:

...
    steps:
      - uses: MPLew-is/lfs-check-action@1

That's it - this action takes no inputs and returns no outputs, only returning a status code about whether the LFS validation succeeded.
