Sania Kill developed a CI disk usage monitoring feature for the TourmalineCore/pelican-ui repository, focusing on enhancing test observability and reliability. She added a dedicated step to the GitHub Actions workflow that logs Playwright browser cache disk usage during test runs, using YAML to define the CI/CD process. This approach provided actionable metrics for resource consumption, enabling proactive capacity planning and reducing the risk of build failures caused by disk-space constraints. Sania’s work demonstrated a strong understanding of CI/CD instrumentation and workflow governance, delivering a targeted solution with minimal disruption to existing processes and no reported bugs during the period.
