Developed the initial Safety Chat Plugin for the langgenius/dify-plugins repository, establishing the foundational architecture and scaffolding required for future extensibility. Focused on modular plugin development, the work introduced a dedicated plugin file and extensibility points to support safer runtime integration and streamlined feature expansion. The implementation emphasized maintainable design patterns, reducing the need for future refactoring and enabling quicker delivery of new features. Throughout the process, maintained a clean and traceable commit history by focusing on a single, well-defined feature addition. Leveraged skills in plugin development, TypeScript, and modular software design to deliver a robust starting point for the plugin.
