During June 2025, contributed to the langgenius repositories by developing a feature that enabled handling arrays of files within the conversation variable system, allowing users to input and validate multiple file attachments in workflows. This work, implemented in the dify repository using Python and TypeScript, integrated seamlessly with existing variable management to expand workflow flexibility. Additionally, addressed a reliability issue in the dify-plugin-daemon by introducing a blocking write mechanism for response data, preventing data loss during large tool or LLM outputs. These efforts focused on backend development and bug fixing, resulting in improved data integrity and enhanced workflow resilience.
