Worked on the langgenius/dify-plugins repository, focusing on codebase hygiene by removing the deprecated dify-plugin-atlascloud package. This cleanup streamlined the repository, eliminated outdated files, and reduced technical debt, directly lowering the risk of legacy regressions and improving build stability. The approach centered on disciplined repository management and dependency cleanup, using Git for precise version control and documentation updates. Although no critical bugs were reported or fixed during this period, the removal of obsolete code reduced the future bug surface and maintenance burden. The work enhanced onboarding clarity and contributed to a leaner, more maintainable plugin architecture for ongoing development.
