Introduction to the DeepSeek Harness Canvas-Pro Plugin

The `dsh-plugin-canvas-pro` plugin for DSH (DeepSeek Harness) aims to fill the gap left by the lack of patching, version rollback, and persistent storage when agents generate content such as HTML and Mermaid. Using a Web Drawer and eight model tools, it supports creating, updating, version management, comparison, and export, and enables interaction through text selection. Although there are limitations in React and Mermaid rendering, it provides agents with powerful patching and version control capabilities for directly manipulating UI documents via built-in tools and file storage.
