DeepSeek Harness launches Creator Mode, generating runnable plugins from a single sentence

DeepSeek Harness Launches Creator Mode: Turn an Idea into a Runnable AI Plugin in One Sentence Phoenix Tech Download the App for Exclusive Early Access November 03, 2026 06:45:59 From Beijing Autoplay

Phoenix Tech News (Author/Yu Lei) On November 3, DeepSeek last night launched Creator Mode for its open-source agent platform DeepSeek Harness. The core capability of this mode is: users describe their requirements in natural language, and the agent can write, install, and run a usable plugin on the spot. The DeepSeek Harness team summarizes it as "turning ideas into plugins you can use."

DeepSeek Harness is based on Cordis's "everything is a plugin" architecture, in which tools, skills, and interface components can all be extended through plugins. Previously, users mainly installed existing plugins; Creator Mode hands plugin production power to users—writing plugins through conversation. The official demo shows that after a single-line request is issued, the agent completes the construction, installation, and verification of a floating Pomodoro timer plugin in about five and a half minutes.

The demo use cases cover professional tool forms beyond "productivity gadgets." The official prompt collection lists seven reproducible scenarios: a 3D gallery of famous landmarks, an interactive 3D demonstration of Transformer internal computation, a pixelated visual style switcher for the app, a poster design workbench, a video editing workbench with a timeline and previewer, a paper reader, and a usage statistics plugin based on real conversation data.

Attached are the 7 complete official demo cases and their corresponding prompts:

1. 3D Gallery of Famous Landmarks

Add a feature entry in the left sidebar to generate 3D models of the Eiffel Tower in Paris, the Great Wall of China, the Forbidden City, and one landmark chosen autonomously by the AI.

English prompt:

Create a DeepSeek Harness plugin with a left sidebar entry that renders 3D models of the Eiffel Tower in Paris, the Great Wall of China, the Forbidden City, and one more famous building of your choice.

2. Transformer 3D Visualization Game

Generate an interactive 3D demonstration game in the left sidebar that intuitively shows the computation logic inside the Transformer architecture, while requiring the interface to avoid the native macOS window buttons to prevent the toolbar from overlapping or obscuring them.

English prompt:

Create a DeepSeek Harness plugin with a left sidebar entry: an interactive 3D demonstration game that helps me understand the computation inside a Transformer. Keep the panel title and toolbar clear of the native macOS window buttons so they do not overlap.

3. Global Pixel-Style Interface Switcher

Provide a skin-switching entry in the left sidebar that lets users change the visual style of the entire application, with 5 different appearance options preset, including a complete retro pixel style.

Create a DeepSeek Harness plugin with a left sidebar entry that lets me change the look of the entire app. Offer five different styles to choose from, with a pixelated look as one option.

4. Poster Design Workbench

Open the poster design panel directly from the current conversation. Use the same shader background texture and English font as the DeepSeek Harness official website, and allow users to customize the poster title, body text, and background color. Keep the interface minimalist, remove all unnecessary subtitles, and fix the default poster title as Everything is a plugin.

Chinese prompt:

English text is being prepared.

English prompt:

Create a poster design workbench plugin accessible from the conversation. Use the shader background pattern and English font from the DeepSeek Harness website. Let me customize the poster title, text, and shader colors. Keep the default page minimal, with no unnecessary subheadings or information. Set the default poster title to Everything is a plugin.

5. Video Editing Workbench

Open the video editing interface from the conversation, using a dark theme and the interaction scheme of mainstream editing software. Place the main video preview window at the top and the editing timeline below, support users in uploading multiple clips, cutting and splicing, and exporting the finished product, and also allow importing and editing videos through natural-language instructions in the dialog box.

Chinese prompt:

English text is being prepared.

English prompt:

Create a video editing workbench accessible from the conversation, using the dark interface and familiar interactions of established video editors. Support uploading multiple videos, editing, and exporting. Place a large preview at the top and a timeline below for importing and editing clips. Also let me import and edit videos through natural-language requests in the conversation

6. Professional Paper Reader

Integrate a lossless paper reader in the right sidebar, fully preserving the original paper layout, fonts, and illustrations. When the user selects text, a floating action bar pops up, offering three functions: underline highlighting, adding annotations, and asking questions in the conversation, with the default question language automatically adapting to the interface language.

Chinese prompt:

English prompt:

Create a paper reader accessible from the right sidebar. Let users upload papers and preserve the original layout, fonts, images, and all other content without any loss. When text is selected, show a floating menu with options to highlight it, add a note, or ask about it in the conversation. Match the default question prompt to the interface language.

7. Conversation Usage and Cost Statistics Dashboard

Read the user's real chat data to generate a visualization dashboard, showing total token usage, total number of sessions, as well as estimated spending and budget quota. Provide a timeline trend of token usage, separately calculate the specific consumption of each session, and monitor and display the system CPU's operating status and utilization in real time.

Chinese prompt:

English text is being prepared.

English prompt:

Create a statistics plugin based on my actual conversation data. Show total token usage, conversation count, and estimated costs and budget based on token usage. Include a token-usage timeline, usage and costs for individual conversations, and CPU activity and utilization.
