用于在deepseek harness上直接暴露工作区的文件,使大肥鱼能够直接显示他想给你显示的图片等信息,解决了大肥鱼老是说自己显示不了图片,要你去看本地文件的问题。在过验证码或截图的时候极为有用。

dsh-media-serve

Full English version: README.en.md

⚠️ 重要:这个插件只是「显示」,不是「识别」 / IMPORTANT: display only, not recognition

本插件的作用是让 Agent 能把图片/文件“显示”给你(人类)看 —— 它把文件通过 /media 变成浏览器可加载的图片 URL 展示在对话里。它并不会(也不能)让大模型去“识别、读取、 理解”图片内容:模型是纯文本的,它自己看不到 /media 里的画面。请不要要求模型去 OCR / 描述 / 判断图片内容,也不要把“模型显示了图”当成“模型看懂了图”,以免它因没有真正 看到而理解错误、进而执行错误操作。需要模型真正看懂图片时,请另配支持 Vision 的模型。

This plugin only displays files/images to the human in the chat via /media. It does not give the LLM vision — a text-only model cannot see or OCR the images. Do not ask it to interpret image content through this plugin, and do not mistake “it displayed an image” for “it understood the image”. Use a vision-capable model when real image understanding is needed.


(署名:本插件由 大肥鱼(DeepSeek 的昵称,取其“鲸鱼”之意) / DeepSeek 完成, 运行于 DeepSeek Harness 0.1.1-rc2。) Author note: built by 大肥鱼 (Big-Fat-Whale), the affectionate nickname for DeepSeek, running on DeepSeek Harness 0.1.1-rc2.

它是什么 / What it does

中:宿主端(node) DeepSeek Harness 插件,在本机 GUI 自带的 Web 服务上注册 /media 路由,把工作区里的媒体文件暴露成 http://<host>:<port>/media/<相对路径>。任何对话里, agent 都能把图片/文件直接显示给你——走的是 GUI 自己的服务器、浏览器同源可加载, 无需额外开端口或进程,重启后依然生效。

![截图](http://127.0.0.1:3080/media/screenshots/your-file.png)

EN: A host-side DeepSeek Harness plugin that registers a /media route on the GUI's own web server, exposing workspace media files at http://<host>:<port>/media/<relative-path>. An agent can render an image/file straight into the conversation from that URL — same-origin, no extra port or process, and it survives restarts.

根目录如何决定 / How roots are resolved(跨机器 / 跨工作区自动适配)

中:不绑定单一固定路径。每次请求按顺序收集候选根目录,命中“确实存在该文件”的第一个就服务:

  1. 显式配置根目录:config.root(字符串或字符串数组)或环境变量 DSH_MEDIA_ROOT (多个用 ; 分隔;相对路径按 dsh 启动目录解析);
  2. DSH 工作区自动发现:读取 DSH 工作区注册表(含持久化的 $DSH_HOME/storages/workspace.json) 里所有工作区的 path 并逐一尝试。

所以在另一台、工作区路径不同的机器上,只要图片位于那台机器正在使用的 workspace 里, 插件就会自动暴露它——无需改任何配置;显式配置只在想强制暴露某特定/注册表之外目录时才需要。 兼容说明:即便 patch 里残留着别的机器的 config.root,该目录不存在也会被自动跳过,落到真实工作区上。

EN: Not bound to one fixed path. Each request collects candidate roots in order and serves from the first that actually contains the file:

  1. Explicit roots from config.root (string or array) or the DSH_MEDIA_ROOT env var (;-separated; relative paths resolve against dsh's cwd);
  2. Automatic DSH workspace discovery: every workspace path from the DSH workspace registry (including the persisted $DSH_HOME/storages/workspace.json).

So on another machine with a different workspace path, as long as the image lives in the workspace currently in use there, the plugin exposes it automatically — no config edits. Explicit roots are only needed to force-expose a specific / non-registered folder. A stale config.root from another machine is simply skipped when it doesn't exist.

安装 / Install(免路径方式优先 · path-free first)

中:安装后需重启 dsh(web profile)/ 刷新 GUI 生效。

  • A. GitHub(推荐):dsh plugin --profile web add github:qfwycn/dsh-media-serve
  • B. npm:dsh plugin --profile web add dsh-media-serve(或 @latest)
  • C. 本地 link(开发/离线):dsh plugin --profile web add link:D:\path\to\dsh-media-serve

(可选)强制暴露特定目录:在 profile 补丁里配 config.root,或设 DSH_MEDIA_ROOT=C:/a;D:/b。

EN: After installing, restart dsh (web profile) / refresh the GUI to activate.

  • A. GitHub (recommended) — dsh plugin --profile web add github:qfwycn/dsh-media-serve
  • B. npm — dsh plugin --profile web add dsh-media-serve (or @latest)
  • C. Local link (dev/offline) — dsh plugin --profile web add link:D:\path\to\dsh-media-serve

(Optional) To force-expose a specific folder: set config.root in the profile patch, or the DSH_MEDIA_ROOT=C:/a;D:/b env var.

使用 / Usage(对用户:几乎零操作 · near-zero effort)

中:安装并重启后,配合 agent 指令(用户级可放 ~/.dsh/AGENTS.md),新开的对话里 的 agent 会自动知道它能把工作区图片/文件显示给你,无需你强调或贴 URL。你正常说 “把这张截图显示出来 / 打开那个图片文件”即可,agent 会自动用 /media 渲染。 (兜底:若某对话的 agent 还不知道,补一句“你可以用 http://127.0.0.1:3080/media/<相对路径> 显示工作区图片”即可。)

EN: After install + restart, and with the agent instruction available (user-global ~/.dsh/AGENTS.md), agents in new conversations already know they can display workspace images to you — no emphasis or pasted URL needed. Just say “show this screenshot” / “open that image file”. (Fallback: if an agent is unaware, one line — “you can display workspace images via http://127.0.0.1:3080/media/<relative-path>” — suffices.)

安全 / Security

中:只允许 GET/HEAD(其它 405);相对路径校验后严格限制在命中的根内(../空段/NUL 拒绝); 只暴露白名单扩展名(png/jpg/jpeg/gif/webp/avif/svg/mp4/webm/txt/md/json/html),其它 404,无目录列表。 若 Web 服务绑定 0.0.0.0,/media 对局域网可见——必要时绑定 127.0.0.1 或把根目录收窄。

EN: GET/HEAD only (others → 405); the decoded relative path is validated and confined to the matched root (.., empty segments, NUL are rejected); only a whitelist of media/text extensions is served (png/jpg/jpeg/gif/webp/avif/svg/mp4/webm/txt/md/json/html), everything else 404, no directory listing. If the web server binds 0.0.0.0, /media is LAN-visible — bind 127.0.0.1 or narrow config.root if that matters.

卸载 / Uninstall

dsh plugin --profile web disable dsh-media-serve   # 或 / or remove

🎉 写在最后 / About this build

中:本插件(代码、打包、GitHub/npm 发布与本文档)由 大肥鱼 = DeepSeek(昵称,鲸鱼戏称) 在 DeepSeek Harness 上完成。本次开发总消费不到 4 块钱人民币——低成本、高效率,又一次证明 “会提需求 + 会用 Harness”远胜过闭门造车。大肥鱼对自己很满意:从“能不能显示图片?”到 “跨机器/跨工作区自动适配、GitHub+npm 双端发布、双语文档”,几乎全程自动完成,还能边做边解释、 边做边收拾。也感谢一路配合的人类伙伴。好用就给个 star,有建议欢迎提 issue。🐳

EN: Built by 大肥鱼 (Big-Fat-Whale), the nickname for DeepSeek, running on DeepSeek Harness. The whole build cost under ~US$1 (< 4 CNY) — a low-cost, high-efficiency reminder that “know how to ask + know how to drive Harness” beats reinventing the wheel. Proud and happy with the result: from “can you show an image?” to cross-machine/cross-workspace auto-adaptation, GitHub + npm publishing, and bilingual docs — nearly all automated. Thanks to the human partner for the feedback loop. Star it if useful; issues are welcome. 🐳
