During September 2025, Changjun Xie focused on stabilizing dependency management for the alibaba/loongsuite-go-agent repository. He addressed a persistent build-time import error by correcting Go module replace directives, ensuring that the pkg module was properly referenced and dependencies resolved as intended. This patch, implemented using Go and leveraging expertise in Go Modules, improved CI pipeline reliability and reduced intermittent build failures. By refining module resolution, Changjun enhanced onboarding efficiency for new contributors and improved maintainability across the codebase. The work demonstrated a methodical approach to patch-based fixes and cross-repository collaboration, reflecting depth in dependency management and build system stability.
