Tomas Kasparek enhanced deprecation governance in the microsoft/azure-pipelines-agent repository by updating PowerShell scripts to detect and flag pipelines using deprecated Ubuntu 20 images. He extended the list of deprecated image names within the deployment script, centralizing image retirement data to improve maintainability and policy alignment. This scripting work ensures that pipelines relying on end-of-life images are automatically identified, reducing the risk of unsupported builds and helping customers plan timely migrations. By focusing on automation and maintainability, Tomas contributed to clearer upgrade paths and more reliable CI processes, demonstrating depth in scripting and infrastructure management using PowerShell.
