dsh-better-markdown

dsh-better-markdown addresses the inconsistent Markdown experience in DeepSeek Harness Web when assistant replies are streamed. It hands streaming assistant Markdown over to markstream-react, so partially unclosed bold text, code fences, lists, tables, and math can continue to be parsed progressively, and the same renderer remains in use after the message settles.

The plugin supports common Markdown, tables, task lists, KaTeX math, Mermaid diagrams, and streaming code blocks with Shiki highlighting, while preserving Harness safety policies for raw HTML, links, and images. It works through Harness public client modules and slot shadowing without modifying Harness source code, and the built-in renderer can take over if the plugin renderer fails.

This plugin is a good fit for DeepSeek Harness Web users who frequently read long answers, code snippets, formulas, or diagrams and want a more consistent experience from streaming output to final rendering.
