dsh-mermaid-web is a DeepSeek Harness Web UI plugin designed to render Mermaid code blocks in Markdown into interactive SVG diagrams. It provides zoom controls, a full-screen workspace, Hot Module Replacement (HMR), and keyboard shortcut support. The plugin relies on the DOM structure for rendering and supports error handling as well as a strict security mode. Developers can install it directly using a pnpm command without a build step.
