DeepSeek Harness CAD Plugin: A Read-Only DWG/DXF Toolkit

dsh-cad-plugin is a read-only CAD file processing toolkit designed specifically for DeepSeek Harness to ensure data security and resource isolation. Through three native tools—cad_inspect, cad_extract, and cad_export—it supports metadata inspection, content extraction, and SVG/PNG export for DWG/DXF files. It is easy to install and requires referencing file paths within the working directory during use. The plugin incorporates strict resource limits and DXF validation mechanisms to ensure the secure processing of large files and the accuracy of converted results.
