Developed a Debug Adapter Protocol (DAP) server for the ubicloud/runner repository, enabling interactive debugging of GitHub Actions workflows. This work established a foundation for workflow-level debugging by supporting step execution, variable inspection, and command evaluation during workflow runs. The implementation focused on backend development using C# and API design, integrating the DAP server directly into the CI pipeline to streamline troubleshooting. By providing a structured debugging interface, the solution improved the developer experience and reduced time spent diagnosing issues. The feature was delivered through collaborative development, emphasizing code quality and maintainability while enhancing the overall debugging capabilities for CI workflows.
