dsh-design
Clickable HTML prototypes inside DeepSeek Harness.
What it does
- Agent tools (
design_*) write HTML under.dsh-design/ - Preview is a scaled artboard at the platform size
- Click the page, drop pins, and continue in the same chat
Official plugin docs: tools · publish · Cordis
Requirements
- DeepSeek Harness web profile, Node.js 22+
- dsh-better-sidebar for the sidebar tab (optional; tools still write files without it)
Two places to open Prototype (toolbar checkboxes):
| Entry | Where |
|---|---|
| Sidebar tab (on by default) | better-sidebar + → Prototype |
| Chat tab (off by default) | in-chat view tab |
Install
From this directory:
dsh plugin --profile web add .Restart DSH. Open better-sidebar + and choose Prototype.
dsh plugin installs into $DSH_HOME/profiles/web and appends the bundle because package.json declares dsh.bundle.patch.
If add fails with pnpm v11.12.0 is a broken release, bump the profile packageManager pin (for example pnpm@11.22.0) and run the same command. That pin is not in this package.
Use
- In chat: “Make a login page.” If you did not already say platform / look, the agent asks: web, iOS, or Android? paper or ink?
- It calls
design_createthendesign_write. HTML lands under.dsh-design/. - The Prototype tab shows a scaled artboard:
- web 1280×800, iOS 390×844, Android 412×915
- several prototypes in one workspace → pick from the strip under the toolbar
- − / % / + zoom · Pan or hold Space and drag · two-finger scroll to pan · ⌘/Ctrl+scroll to zoom
- Pin: click a spot, write a note, then mention it in chat. The agent reads pins before rewriting.
Files may nest two folders. HTML can <link href="css/app.css">, <a href="settings.html">, <img src="https://raw.githubusercontent.com/xbyzzz/dsh_design/main/assets/logo.png">. Raster images use encoding=base64. design_systems with id=paper or ink loads a sample page.
Looks:
