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.
TangSan portrait
TangSan wallpaper
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.
| Field | Default | Meaning |
|---|
wallpaper | true | Wear the TangSan artwork as the GUI background |
brand | true | Replace the sidebar and hero logos with the TangSan avatar |
surfaceOpacity | 60 | Shell surface opacity in % — lower shows more of the wallpaper, higher keeps the shell opaque (25–100) |
blur | 0 | Gaussian blur applied to the wallpaper, in px (0–24) |
scrim | 35 | Palette-matched wash over the wallpaper — black in the dark theme, white in the light theme — for a readable transcript, in % (0–90) |
position | center | Wallpaper background-position: center, left, right, top, bottom |
| Route | Method | Purpose |
|---|
/api/tangsan/config | GET / PUT | Read / write the config (writes are same-origin only) |
/api/tangsan/wallpaper | GET | The 16:9 background artwork |
/api/tangsan/mark | GET | The square avatar artwork |
/api/tangsan/diag | GET / POST | Last browser-side diagnostic report (mount state, surface overrides, errors) |
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:
| Field | Value |
|---|
dsh.bundle.patch | ./cordis.patch.yml — what makes this package an installable profile bundle |
dsh.client | platform: web, so the browser half ships with the bundle |
locale/en.json, locale/zh.json | card title and description (meta.title, meta.description) |
icon | ./assets/tangsan-mark.jpg — the card artwork (SVG/PNG/JPEG/WebP, at most 256 KiB) |
exports | ./package.json and ./locale/*.json, the two subpaths the readers resolve |
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:
| 字段 | 值 |
|---|
dsh.bundle.patch | ./cordis.patch.yml —— 让这个包成为可安装 profile bundle 的关键 |
dsh.client | platform: web,浏览器半随 bundle 一起分发 |
locale/en.json、locale/zh.json | 卡片标题与描述(meta.title、meta.description) |
icon | ./assets/tangsan-mark.jpg —— 卡片配图(SVG/PNG/JPEG/WebP,上限 256 KiB) |
exports | ./package.json 与 ./locale/*.json,读取方解析的这两个子路径 |
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。
