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 D (68).

    Tests18pt

    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

    Add CI/build status badges from shields.io or your CI provider to signal project health.

  4. 4
    Install and run instructions9pt

    Add a section showing how to install dependencies.

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.
