dsh-md-view

A DeepSeek Harness (DSH) plugin: markdown rendering for client plugins, so every surface that shows markdown (READMEs, journals, pads) renders it the same way through one service: the harness's own MarkdownText pipeline (GFM, math, footnotes, shiki-highlighted code with copy buttons) plus the document-specific handling chat never needs.

There is no UI of its own to visit. Plugins inject the client service mdView:

// consumer client half — inject: ['mdView', …]

// 1. One markdown document as an element (you keep the layout):
return React.createElement('div', { className: 'mine' },
  ctx.mdView.render(markdownText, { links: { repo: 'owner/name' } }))

// 2. One self-contained document:
const Doc = ctx.mdView.component({ text: markdownText, links: { repo: 'owner/name' } })
return React.createElement(Doc, {})

What it adds to the primitive

• raw <img> tags (badges, screenshots) become real images,
• document-relative link and image targets resolve against https://github.com/{repo}/blob/HEAD/... and the raw content host (when links.repo is given),
• fenced code blocks and inline code spans are never transformed.

Contract

• Rendered output is React elements with plain text nodes only; markdown can never inject HTML (<script> stays visible text — a MarkdownText rule).
• links.repo is optional; without it relative targets stay as written.
• The wrapper stylesheet is installed once by this plugin; consumers add no CSS of their own for markdown.
• No persistence; the host half is a stub.

How to install

Requires a DeepSeek Harness checkout and a profile, here web. The plugin has no dependencies:

mkdir -p ~/dsh-plugins && cd ~/dsh-plugins
git clone https://github.com/joao-paulo-santos/dsh-md-view.git

# from the harness checkout
pnpm dsh plugin --profile web add ~/dsh-plugins/dsh-md-view

# verify the profile still composes
pnpm dsh --profile web --dump-config

Restart the harness. Plugins that inject the mdView service can now render markdown.

• dsh-workspace-history renders compaction journal bodies with it (optional; degrades to plain text)
• dsh-wo-github renders repository READMEs with it (optional; degrades to plain text)
