Worked on the langgenius/dify-official-plugins repository to implement Per-Site Base URL Configuration, enabling each site to maintain an isolated base_url for flexible API endpoint management and reducing cross-tenant risk. The solution involved backend development using Python and YAML, with a focus on robust API integration and configuration management. Release engineering included a version bump and manifest.yaml update to ensure consistent deployment across environments. Collaboration was demonstrated through co-authored commits and coordination on manifest changes. The work addressed multi-tenant readiness by allowing site-specific settings, resulting in a more adaptable and secure plugin architecture without introducing new bugs during the release.
