@areaartez51/dsh-uml-class: Generate interactive UML class diagrams from JSON specifications

The plugin @areaartez51/dsh-uml-class, maintained by areaartez51, is a skill-only bundle that registers a file system skill named uml-class. It accepts `spec.json` and renders it into a self-contained interactive HTML class diagram featuring inline SVG, zooming, themes, hover highlighting, and node expansion. It supports six types of relationships and package grouping, with a deterministic layout. It does not parse source code and does not make network requests. The article provides installation commands from GitHub Releases or local archives, the C# project's extract/render/check process, usage of hand-written specifications, descriptions of specification fields, the rendering pipeline, exit codes, and testing methods. It also outlines limitations such as a maximum of 800 classes and the absence of PNG/SVG export capabilities. Additionally, it notes that the plugin runs with the permissions of the current DSH process and that source code and license verification should be performed before installation.
