Worked on the google/osv-scanner-action repository to deliver a new feature that adds a runs-on input parameter to reusable GitHub Actions workflows. This enhancement allows users to specify custom runner environments for their CI/CD pipelines while maintaining backward compatibility with the default ubuntu-latest setting. The implementation involved updating both reusable workflow files using YAML and leveraging DevOps practices to ensure consistency and reliability. By enabling greater flexibility in workflow execution, the change supports diverse runtime environments and helps users optimize pipeline reliability and cost management. No bugs were reported during this period, reflecting a focused and stable delivery.
