dsh-bridge-preview

DeepSeek Harnessdsh-tool-vision「图片桥」提供对话内联预览的插件。

解决的问题

纯文本模型(如 deepseek-v4-flash)下,粘贴的图片会被 tool-vision 桥接成一段文本提示:

[User sent an image (image.png), exported to: C:\...\dsh-vision-bridge\image_sha256:xxx.png. Inspect it with the inspect_image tool to see its content.]

对话里只显示文字、看不到图片。本插件在展示层把这段提示中的图片路径渲染成内联缩略图——模型看到的提示文本、inspect_image 调用、日志内容完全不变

特性

  • 用户气泡内直接显示图片预览(缩略图,点击可看大图)
  • 旧消息自动补预览、新消息即时预览(观察器 + 2s 兜底扫描)
  • 纯加法:不修改持久化消息、不碰插槽系统、不影响模型请求
  • 加载失败静默降级(自动移除,不破坏对话)

安装

dsh plugin --profile web-desktop add github:xing666173/dsh-bridge-preview

重启 dsh(或硬刷新页面)后生效。需要已安装并启用 dsh-tool-vision 的图片桥(bridgeTextOnly: true,默认)。

工作原理

  • 服务端(index.js):注册同源回环路由 /plugins/dsh-bridge-preview/image,只读桥接导出目录(<os.tmpdir>/dsh-vision-bridge)内的图片;限制本机 Host、图片扩展名、20MB 上限、防目录穿越。
  • 浏览器端(client.js):扫描用户消息中的 exported to: <path> 提示,提取路径,在文本块上方插入 <img>

> 注意:Windows 上 tool-vision 导出的文件名含冒号(image_sha256:xxx.png),实际是 NTFS 备用数据流(ADS),Node 可直接读取,无需特殊处理。

兼容性

  • 桥接提示格式:exported to: <path> 段在 tool-vision 0.3.7 / 0.3.10 中保持一致
  • 若上游更改提示文本格式,需同步更新 client.js 中的 HINT_RE
