Developed Windows CI platform support for the umijs/mako repository, enabling comprehensive cross-platform testing and streamlined release processes. This work involved updating CI workflow scripts and configurations to ensure full compatibility with Windows environments, using Rust, Shell scripting, and YAML. The implementation addressed platform-specific permission handling in the downloader, reducing build failures and improving reliability across operating systems. By expanding test coverage and automating validation on Windows, the changes accelerated release cycles and enhanced the robustness of the CI/CD pipeline. The approach focused on maintaining parity with existing environments while optimizing script services for consistent performance in Windows-based workflows.
