During September 2025, Deepin-admin-bot enhanced CI/CD workflows for the linuxdeepin/dde-control-center and linuxdeepin/dde-file-manager repositories. Focusing on reliability and security, they upgraded GitHub Actions checkout from v3 to v4 and improved secret management by removing inherited secrets in YAML-based workflows. These changes aligned both repositories with central governance standards, reducing maintenance overhead and risk in automated builds. By leveraging CI/CD best practices and GitHub Actions, Deepin-admin-bot delivered faster feedback loops for developers while maintaining existing product functionality. The work demonstrated a solid understanding of workflow automation and secure configuration management using YAML and modern CI tooling.
