Plan on Pull Request

Review infrastructure changes before merging a pull request. Run an Atmos plan in GitHub Actions and publish the results as job summaries, checks, and pull request comments.

Use Setup Atmos to pin the Atmos container version, enable native CI reporting, and configure authentication and permissions for your repository.
