DeepSeek Harness's Creator Mode: Someone wishes for a feature, switches back to another session, and the button is already there

DeepSeek Harness (hereinafter DSH) has launched Creator Mode. The official tweet describes it as turning ideas into usable plugins, with examples including a design workspace, sandbox games, and a 3D LLM visualizer. Tianyi Cui asked on X how people who had tried it were finding it.

In a reply, the official account posted the collection of prompts for the plugins shown in the video, in both Chinese and English: https://cdn.deepseek.com/harness/dsh-creator-mode-prompt-collection-en.html . If you want to reproduce what's in the video, you can copy from here.

The comment section first turned into a feature-request pool. One user posted a screenshot of the Claude interface with the caption “claude no dsh yes!”. Another user said they had tried Creator Mode and were impressed. They wished for a way to remotely upload and download workspace files, and DSH ended up adding file renaming, deletion, and new-folder creation along with it.

A more specific piece of feedback came from Vinen. He clearly stated his requirements in the Creator Mode session, then went to another session to continue working. While he was working, a new feature suddenly appeared in the interface—it turned out the Creator Mode session had already finished. He said he hadn't experienced this on Pi.

The direction of Creator Mode is clear: let users build their own plugins. The problems are clear too. One user installed a vibe plugin, but the client didn't show any effect; after restarting, they found that DSH had crashed; clicking backup and starting again did nothing; and finally they discovered that the dependencies used by the plugin hadn't been installed. They hope the plugin system's crash protection can be made more robust. Others are asking whether superagent should be made into a fourth mode, when the official version will arrive, when HarmonyOS will launch, whether a Telegram plugin can be made, and what to do about DSML tag leakage. Someone else hopes to be able to manually or automatically add a confirmation to switch to Creator Mode within a session. The motion design also got a complaint.

The official team has opened up a lot of room for imagination, but the plugin ecosystem hasn't caught up yet. Users are already making requests in the form of “wishes,” and Creator Mode has turned that into a product path. What remains to be seen is whether plugin dependencies, crash recovery, and mode switching can be stabilized first.
