Looks good! I think it might be nice to make this a little higher level such that it will also autoclose an issue on success and open a new issue on failure. Maybe even post more comments on repeated failures? Thoughts?

Sorry, have been a little bit busy this week. I'll get back to this soon.

I think it might be nice to make this a little higher level such that it will also autoclose an issue on success and open a new issue on failure. Maybe even post more comments on repeated failures? Thoughts?

How about this: we turn this into an action that's able to perform the following depending on ${{ steps.some-previous-step.conclusion }}:

• failure: looks for an issue with the same title, and post a new comment under it if found, or open a new one otherwise.
• success: closes an issue if there exists one with the title.

With usage like:

- uses: Homebrew/actions/create-issue@master
  with:
    token: ${{ github.token }}
    repository: ${{ github.repository }}
    update-existing: true
    close-existing: true
    dependent-step-conclusion: ${{ steps.deploy.conclusion }} 
    title: Deployment failed
    body: Issue body (or comment to post if issue already exists)
    labels: label1,label2
    assignees: user1,user2
