dsh-design

English 中文

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

1. In chat: “Make a login page.” If you did not already say platform / look, the agent asks: web, iOS, or Android? paper or ink?
2. It calls design_create then design_write. HTML lands under .dsh-design/.
3. 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
4. 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="assets/logo.png">. Raster images use encoding=base64. design_systems with id=paper or ink loads a sample page.

Looks:

id	Use
paper	Light product UI (auth, settings, content)
ink	Dark operations UI (admin, tables, dashboards)

Agent tools

Tool	Role
design_status	Projects in this workspace and the file currently previewed
design_systems	Platforms, default artboards, and paper / ink
design_create	New project; pass platform and designSystem from discovery
design_brief	Complete or change the brief on an existing project
design_write	Write html / css / js / svg / raster; first HTML needs a complete brief
design_list	List files in a project
design_open	Point preview at an existing HTML file or another project
design_comments	Read canvas pins (x,y in 0..1, optional CSS selector) before rewriting

Storage

<workspace>/.dsh-design/
  current.json
  projects/<id>/
    project.json
    comments.json
    index.html
    css/app.css
    assets/logo.png
    settings.html

Safe to commit or gitignore. Paths stay under .dsh-design. Single file cap is 512 KiB (maxFileBytes).

Config

The bundle ships cordis.patch.yml. Official patches replace config wholesale. To override:

- insert:
    - id: dsh-design
      name: dsh-design
      config:
        maxFileBytes: 524288

Develop

node --test test/*.test.js

Tests use Node builtins only.
