tangsan

TangSan mascot appearance layer for the DeepSeek Harness Web GUI — a generated 唐三 (TangSan) portrait, shipped inside the plugin, worn by the harness as its background, its brand mark, and its settings surface.

What it does

• Chat background — the shipped 16:9 artwork is mounted as a fixed, click-through layer behind the whole GUI. The shell's surface tokens (--dsw-alias-bg-base, --dsw-specific-sidebar-fill, --dsw-alias-bg-layer-1/2) are faded to the configured opacity so the wallpaper actually shows through instead of hiding behind an opaque shell, and the root background is cleared for it.
• Controls — opacity of the shell surfaces, wallpaper blur, a dark scrim for readability, and background-position, all applied live.
• Brand mark — the square TangSan avatar replaces the logo in the sidebar and the conversation hero through the stock sidebar.brand.mark and conversation.hero.brand.mark slots.
• Settings section — a 「唐三美化 TangSan」 page in Settings edits everything, with previews of both artworks, and applies on save.
• Tab icon — the browser tab favicon follows the same TangSan avatar while the brand mark is on, and the stock icons come back when it is switched off.
• Host half — serves the artwork and the config from the local DSH web server (/api/tangsan/...), so the browser never reaches outside, and stamps the config into the HTML so the GUI comes up already dressed.

Install

DeepSeek Harness Desktop — install it from the application, not from a shell: open Plugins in the sidebar, choose Add plugin, enter

https://github.com/bauerelizabeth07139/tangsan

and switch the new tangsan bundle on. The Desktop application boots the reserved desktop profile, so the command below installs into a different profile that the Desktop app never reads.

dsh CLI (web profile) — install it into the profile you boot:

dsh plugin --profile web add bauerelizabeth07139/tangsan

No git on the machine? pnpm resolves a git shorthand with git ls-remote, so an owner/repo or github: spec fails with 'git' is not recognized when git is missing from PATH. Install the published tarball over plain HTTPS instead — that path never calls git:

dsh plugin --profile web add https://codeload.github.com/bauerelizabeth07139/tangsan/tar.gz/main

The same address works in the Desktop application's Plugins → Add plugin dialog. Pin the revision by replacing main with a commit SHA (/tar.gz/<sha>) when you want a fixed build.

Any spec the plugin manager accepts works — a GitHub shorthand, a full git URL, or a local checkout:

dsh plugin --profile web add https://github.com/bauerelizabeth07139/tangsan.git
dsh plugin --profile web add C:\path\to\tangsan

Then open Settings → 唐三美化 TangSan. Uninstall with dsh plugin --profile web remove tangsan.

Configuration

The config lives at $DSH_HOME/tangsan.json (default ~/.dsh/tangsan.json) and is edited by the Settings section; it is also reachable over HTTP.

Every value is clamped server-side; unknown keys are dropped.

Artwork provenance

Both artworks are generated with the SenseAudio 同步图片生成 API (model senseaudio-image-2.0-260319): the portrait from a user-supplied reference image, and the wide wallpaper from that portrait. Derivatives — the 512×512 avatar mark and the shipping JPEGs — are cropped from those two generations.

Development

No build step, no runtime dependencies (React and @deepseek-ai/cordis are peers supplied by the harness).

npm test   # node >= 22: host routes/config/stamp tests + client DOM-stub tests

• lib/index.js — the host half: config file, three routes, HTML boot stamp.
• lib/client.js — the browser half: wallpaper layer, surface fade, brand-mark slots, Settings section.
• cordis.patch.yml — the loader row that makes both halves load.

Plugin metadata

The manifest declares what the Harness and the plugin catalogs read without activating the plugin:

Both locale files and the icon are resolved through the package specifier, so a package that keeps exports sealed without these subpaths shows up under its bare package name instead of its title.

Troubleshooting

The application does not start: ... is not valid JSON

The Harness Host reads each profile manifest as JSON before it loads any plugin, so one stray , before the opening { of a manifest makes the read throw and the application stop. The Desktop recovery action "Disable third-party plugins" cannot repair it: it re-reads the same broken manifest.

Find the damaged file — the Desktop application boots $DSH_HOME/profiles/desktop ($DSH_HOME defaults to ~/.dsh):

$home = if ($env:DSH_HOME) { $env:DSH_HOME } else { Join-Path $env:USERPROFILE '.dsh' }
Get-ChildItem (Join-Path $home 'profiles\*\package.json'), (Join-Path $home 'profiles\*\node_modules\*\package.json') -ErrorAction SilentlyContinue |
  ForEach-Object { try { $null = Get-Content $_ -Raw | ConvertFrom-Json; "OK   $_" } catch { "BAD  $_" } }

A BAD file whose first non-space character is a comma is otherwise intact: delete that one character. Deleting the whole file also works when it is the profile manifest — the next start re-creates it from the shipped template and only the bundle selection is lost, because installed packages stay in the profile's node_modules; switch tangsan back on from Plugins. While the manifest is broken, neither dsh plugin nor the Plugins page can run.

中文

DeepSeek Harness 网页端的唐三美化形象插件 —— 一张生成的唐三插画随插件一起分发，由 Harness 当作背景、品牌标识与设置项穿在身上。

功能

• 聊天背景：内置 16:9 横版插画作为不可点击的全屏背景层；同时把界面的表面色令牌（--dsw-alias-bg-base、--dsw-specific-sidebar-fill、--dsw-alias-bg-layer-1/2）按设定透明度调淡，背景才能真正透出来，而不是被不透明的界面挡住。
• 可调参数：界面不透明度、背景模糊、暗色遮罩、壁纸位置，改动即时生效。
• 品牌标识：通过官方的 sidebar.brand.mark 与 conversation.hero.brand.mark 插槽，把侧栏与会话标题处的 logo 换成唐三方形头像。
• 设置页：Settings 里的「唐三美化 TangSan」页面提供两 artwork 预览与全部开关，保存即生效。
• 标签页图标：品牌标识开启时，浏览器标签页小图标也换成同一张唐三头像；关闭后恢复官方图标。
• 宿主半：由本地 DSH Web 服务直接提供 artwork 与配置接口（/api/tangsan/...），浏览器无需访问外部网络；配置同时被盖进 HTML，页面一打开就是美化后的样子。

安装

桌面版 DeepSeek Harness:请在应用内安装——侧栏 Plugins → Add plugin,填入

https://github.com/bauerelizabeth07139/tangsan

然后打开 tangsan 这个 bundle。桌面版启动的是保留 profile desktop,而下面的命令行会把插件装进另一个 profile,桌面版不会读取它。

dsh 命令行(web profile):装进你实际启动的 profile。

dsh plugin --profile web add bauerelizabeth07139/tangsan

机器上没有 git? pnpm 解析 git 形式的依赖时会调用 git ls-remote,owner/repo、github: 这类写法在 PATH 里找不到 git 时会直接报 'git' 不是内部或外部命令。改成用 HTTPS 直接下载 tarball 即可,这条路径完全不需要 git:

dsh plugin --profile web add https://codeload.github.com/bauerelizabeth07139/tangsan/tar.gz/main

同样的地址也能填进桌面版的 Plugins → Add plugin。想要固定版本,把 main 换成提交 SHA (/tar.gz/<sha>) 即可。

随后打开 Settings → 唐三美化 TangSan。卸载：dsh plugin --profile web remove tangsan。

配置

配置文件为 $DSH_HOME/tangsan.json（默认 ~/.dsh/tangsan.json），字段与取值范围见上方英文表格；服务端会做钳制并丢弃未知字段。

素材来源

两张插画均由 SenseAudio 同步图片生成接口（模型 senseaudio-image-2.0-260319）生成：竖版画像以用户提供的参考图为底，横版壁纸再以该画像为参考图生成；512×512 头像等衍生图由这两次生成裁切而来。

开发

npm test   # 需要 node >= 22，无任何运行时依赖

插件元数据

manifest 里声明了 Harness 与插件目录在不激活插件的情况下会读取的字段:

两个语言文件与图标都是通过包名解析的:若 exports 没有开放这两个子路径,插件在列表里 只会显示裸包名,而不是这里的标题。

疑难解答

应用无法启动,报 ... is not valid JSON

Host 在加载任何插件之前会把每个 profile manifest 当作 JSON 读取;只要某个 manifest 开头的 { 之前多出一个 ,,这次读取就会抛错,应用随之停止。桌面版 的「禁用第三方插件」恢复按钮修不好它,因为它会重新读取同一个坏文件。

定位损坏的文件(桌面版启动的是 $DSH_HOME/profiles/desktop,$DSH_HOME 默认 为 ~/.dsh):

$home = if ($env:DSH_HOME) { $env:DSH_HOME } else { Join-Path $env:USERPROFILE '.dsh' }
Get-ChildItem (Join-Path $home 'profiles\*\package.json'), (Join-Path $home 'profiles\*\node_modules\*\package.json') -ErrorAction SilentlyContinue |
  ForEach-Object { try { $null = Get-Content $_ -Raw | ConvertFrom-Json; "OK   $_" } catch { "BAD  $_" } }

报告为 BAD 且第一个非空白字符是逗号的文件,其余内容是完好的:删掉那一个逗号 即可。如果坏的是 profile manifest 本身,直接删除整个文件也可以——下次启动会按 内置模板重建,只会丢失 bundle 的勾选记录,已安装的包仍留在 profile 的 node_modules 里,在 Plugins 页面重新打开 tangsan 即可。manifest 损坏期间, dsh plugin 与 Plugins 页面同样无法工作。
