Block Merge Commits
Actions
A Github Action to prevent merging pull requests containing merge commits.
If any commit in the pull request is a merge commit, the check status will be set to error.
⚠️ GitHub's API only returns the first 250 commits of a PR so if you're working on a really large PR your merge commits might not be detected.

If your repository is using control permissions you'll need to set pull-request: read on either the workflow or the job.
