A low grade is a to-do list, not a judgment of your code

Most gaps here are documentation, tests, and setup, not the code itself. Closing your top 3 gaps alone would lift this repo to A (91).

    Add automated tests. They prove the code works and give contributors confidence to make changes.

  2. 2
    CI/CD14pt

    If your CI lives elsewhere (a private repo that builds this one) or this project is itself a CI/CD tool, mark this check Not Applicable. Otherwise add a GitHub Actions workflow that runs tests on each push. It takes 15 minutes and reassures contributors their changes won't break things.

  3. 3
    README12pt

    Show a quick-start snippet so contributors can see what using your project looks like.

  4. 4
    Install and run instructions9pt

    Add a section showing how to start or use the project.

Working through the fixes? Let every push regrade itself.

The free GitHub App rescans this repo on every push and posts the grade as a commit check, so the score climbs without coming back to rescan by hand.
