DeepSeek Harness Plugin dsh-diffstream: Show Code Changes Directly in the Conversation Flow

dsh-diffstream is a Web plugin for DeepSeek Harness (DSH) designed to address the difficulty of tracking code changes. It displays line-level diffs in real time within the conversation flow, supports streaming animations and end-of-turn change summaries, and is compatible with Git or pure parameter-based comparisons. By taking over the rendering logic, the plugin achieves zero-latency display, offers simple installation and configuration, and greatly enhances the visual experience of debugging agent-generated code.
