SpecDev Workbench: DSH 3D Spatial Documentation and Room Browser

SpecDev Workbench is a plugin for DeepSeek Harness, designed to convert business materials such as documents and charts into interactive 3D rooms. Users can browse content within the space, use AI skills to generate forest- or ceramic-themed scenes, and make use of walk-through interaction, atmosphere control, and offline export. The plugin is used together with DSH; after installation, users can register materials, create rooms, and explore exports to achieve immersive project visualization.
