DeepSeek Harness File Attachment Plugin Overview

`dsh-file-attachment` is a plugin designed specifically for DeepSeek Harness. It addresses the limitations of native file uploads and embodies the “everything is a plugin” philosophy. The plugin supports drag-and-drop, pasting, and click-based multi-file upload, uniformly saving images and documents to the session workspace and making them available to text models through `@path` references. Core features include inline preview in the input field, rendering in the chat area, cross-platform support, and intelligent VLM recognition for non-multimodal models. Installation is simple and requires adding the plugin via CLI. It standardizes file storage and referencing, significantly improving the AI Agent’s interaction experience when handling documents and images.
