dsh-diagram-design
Diagram Design tools and gallery for DeepSeek Harness: export HTML diagrams to SVG/PNG, import from draw.io / Mermaid / Excalidraw, validate output, and browse a gallery of 45 diagram types.
What it does
A DeepSeek Harness bundle with four agent tools and a web gallery panel:
| Tool | What it does |
|---|---|
diagram_export |
Export a diagram-design HTML file to a standalone SVG and/or PNG. |
diagram_extract |
Parse a draw.io / Mermaid / Excalidraw file into a normalized digest for redrawing. |
diagram_self_check |
Validate a generated diagram HTML file (accessible-SVG, single-file safety, viewBox). |
diagram_doctor |
Diagnose the environment: bundled scripts, python3, Playwright availability. |
The gallery panel (sidebar "Diagram Gallery") lists the 45 diagram types with
live example previews.
Install
dsh plugin add github:Shang-ZZ/dsh-diagram-design
PNG export is the only feature that needs an extra dependency, installed once
on demand (never automatically):
pip install playwright && playwright install chromium
