Edit workspace .md files right inside the DeepSeek Harness right sidebar.
Click a .md in the official workspace file tree → it opens in the right sidebar as an
editable Monaco tab. Type, pause, and it saves itself. No separate page, no copy-pasting
into another editor.

On the Electron desktop build the desktop profile is owned by the app itself, so the CLI cannot
install into it — use Settings → Plugins → Add plugin and paste the local path or package name.
Then fully restart DSH (host-side JavaScript modules are cached per process) and make sure the plugin is enabled in the plugin list.

and is safe to delete.Two halves, declared in package.json:
| Half | File | Responsibility |
|---|---|---|
| Host | index.js | serves Monaco assets at /api/md-editor/monaco via ctx.connection.fetch.register; registers the /md-save command |
| Host | monaco.js | same-origin Monaco asset resolution, with traversal and symlink checks |
| Browser | client.js | registers the tab type and renders the editor |
Key APIs, all verified against official implementations:
// browser half — first-layer extension point (stable; body fully self-controlled)
ctx.sidebarRightTabs.register({
id: 'dsh-md-editor', kind: 'md-editor',
patterns: ['*.md', '*.markdown'], // glob — WITH the dot
priority: 'extension',
title: () => 'Markdown editor',
});
ctx.slots.inject('sidebar.right.pane.tab', () =>
ctx.slots.register({ name: 'sidebar.right.pane.tab', key: 'dsh-md-editor' }, Body));
// Cordis service dependencies must be declared verbatim
inject: ['slots', 'sidebarRight', 'remote', 'remote.workspaceFiles', 'remote.commands']
ctx.remote.workspaceFiles.read(...) — that service is read-only./md-save command, and the host
writes with ctx.fs.writeText(resolved, content, guard, undefined, policy).cwd when resolving the path — otherwise relative
paths resolve against the process working directory and you get a "successful" write to the wrong
location.The plugin appends one line per lifecycle stage to .client-beacon.log in its own directory
(via a /api/md-editor/beacon route). It turns "the UI looks wrong" into numbers readable from
disk. Every trap hit while building this is written up in
DSH插件开发-避坑指南.md (Chinese).
