DeepSeek Harness (DSH) adopts a plugin-based architecture, with extensibility mainly achieved through community plugins. During model selection, manually looking up or memorizing model names can be error-prone when dealing with multiple inference providers and different modality capabilities. supanexus/dsh-plugin-chat-enhance aims to optimize this process, improving model switching and identification through a searchable selector and multimodal labels.

This is a model inference plugin maintained by supanexus. It adds a searchable model selector and multimodal “image” capability labels to DSH, and reuses the official input bar’s paperclip function for attachment uploads.

Core Features

  • Recent Models: Displays recently used models next to the input bar, allowing quick switching with a click.
  • Search and Filter: Supports filtering by model name and provider, and provides an “Images Only” filter option.
  • Image Labels: Shows an “image” indicator next to model names that support image input, making them easier to identify.
  • Image Upload: Reuses the official input bar’s paperclip function for attachment selection, requiring no additional configuration.

Installation and Enablement

Use the following command to install the plugin:

dsh plugin --profile web add github:supanexus/dsh-plugin-chat-enhance#v0.3.5

After installation, you must fully restart dsh web (or Desktop Host), and open it using the printed ?token= URL.

Typical Usage

  1. Open any conversation.
  2. Click the model selection area to search or filter. If you need image recognition capability, enable the “Images Only” filter.
  3. To send an image, use the paperclip in the official input bar to select an attachment, then send it.

Applicable Scenarios and Notes

  • Independence: This plugin can perform model searching and switching without depending on SupaNexus Core.
  • Capability Validation: The “image” label and filtering are available only when the current model has declared support for image input; otherwise, these features remain unavailable.
  • Version Requirement: Attachment upload depends on the official dsh InputBar and requires dsh version ≥ 0.1.3. Models without image modality can still attach generic files.

Conclusion

This plugin solves the problem of quickly locating models with multimodal capabilities among a large number of models, reducing operational overhead through labels and search.
