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
