Official examples place these tools in the left sidebar, right sidebar, or conversation flow.
Prompt-Based Custom Plugins and Seven Demo Workspaces
The core premise of Creator Mode is the ability to generate working plugins directly within the harness environment. Users can input a prompt and select the "Creator Mode" option to generate customized interface panels.
The official prompt collection gives specifications for seven demo categories:
- 3D Landmark Gallery: Renders 3D models of famous architecture, such as the Eiffel Tower, the Great Wall, and the Forbidden City, in the left sidebar.
- Transformer 3D Visualization: An interactive 3D demonstration designed to help users understand internal transformer computations.
- Pixelated Interface Theme: Changes the application's visual style, offering five distinct themes including a pixelated look.
- Poster Design Workbench: A minimalist design editor leveraging the shader background patterns and fonts from the official DeepSeek Harness website.
- Video Editing Workbench: A dark-mode timeline interface supporting video upload, natural-language clip editing, and export workflows.
- Paper Reader: Integrated into the right sidebar to render uploaded papers without losing original layouts, fonts, or images, featuring inline text highlighting and notes.
- Conversation Statistics: A monitoring dashboard displaying total token usage, conversation count, estimated costs, and CPU utilization.
The official prompt guide notes that some plugins were refined through several rounds of conversation and that one prompt may not reproduce the video exactly.
Sidebar and Conversational Integration
The seven demo prompts place plugins in the left sidebar, right sidebar, or conversation flow.
In a reply to the announcement, @lizhou_zhu said they had shipped dsh-marktext, a MarkText WYSIWYG editor in the right sidebar with math, Mermaid, tables, autosave, and ⌘S. In another reply, @MSZeghdar asked when a Linux version would be released; no official response appears in the supplied thread.
