Codex-style skin switcher plus a custom wallpaper layer with opacity and blur controls.

Install

# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)

dsh plugin --profile web add github:KinGao294/dsh-skin

Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).

README

Skin switcher + custom wallpaper + 奶龙桌宠（desktop pet with sticker pack） for DeepSeek Harness — a "change the skin" feature in the spirit of Codex themes. It registers a curated catalog of palettes into DSH's built-in theme runtime and adds three rows to Settings → General (below the built-in Appearance row):

  • 皮肤 / Skins — pick one of 7 curated palettes (or 默认 / Default to follow the built-in appearance).
  • 背景图片 / Wallpaper — local image, or paste an image/video URL; opacity, blur, and fit (cover / contain / stretch / tile).
  • 奶龙桌宠 / Pet — a floating, draggable yellow-dragon desktop pet with an 8-mood sticker pack (表情包). It follows the agent's running state (idle → thinking → working → done → sleeping), blinks while idle, falls asleep when idle too long, can be dragged anywhere (position remembered), and shows a 🎨 sticker panel where you can pick any mood manually. Toggle it, resize it, or reset its position from the settings row.

Both choices persist across reloads (localStorage). A saved third-party skin is re-applied once on boot (DSH only persists system/light/dark itself).

How it works

DSH's theme system is token-based: the web shell ships --dsw-* design tokens, and ThemeRuntime lets third-party plugins register themes that override the alias layer (--dsw-alias-*) per color scheme. This package is a regular dual-face plugin:

  • Host half (lib/index.js) — a dsh.bundle patch layer that inserts one loader entry (skin); a no-op apply, exactly like the shipped ui-* packages.
  • Browser half (lib/client.js) — a dsh.client bundle (served at /plugins/dsh-skin/client.js) that:
    1. registers 7 curated skins via ctx.theme.register(...);
    2. restores the saved skin id and applies it with ctx.theme.setTheme(...);
    3. renders the wallpaper as a fixed backdrop layer (z-index: -1) and stacks a token override (ctx.theme.overrideTokens) that makes the main canvas (--dsw-alias-bg-base) and sidebar (--dsw-specific-sidebar-fill) translucent, so the image shows through while inner surfaces (cards, inputs, bubbles) stay opaque and readable;
    4. keeps the slot stores in sync with theme/change (and re-shades the wallpaper when the active skin or light/dark scheme changes);
    5. mounts both rows into settings.general.item;
    6. mounts the desktop pet (a fixed, draggable element with inline-SVG stickers) and watches the agent's running state through ctx.get("sessions").list() to switch moods.

Each skin sets its colorScheme (light/dark), which drives body[data-ds-dark-theme], plus alias-token overrides applied as inline custom properties on <body> by ui-layout's ThemePresenter.

Skins

id scheme vibe
skin-ocean dark DeepSeek-blue deep sea
skin-graphite dark neutral monochrome
skin-forest dark green calm
skin-sunset dark warm purple
skin-midnight dark pure black OLED
skin-paper light warm paper
skin-sakura light pink accents

Ids are namespaced (skin-*) so they do not collide with official @deepseek-ai/dsh-client-ui-console themes (sakura, graphite). Saved unprefixed ids are migrated on read.

Picking 默认 / Default reverts to the built-in appearance (follow system) and clears the stored skin.

Wallpaper

In Settings → General → 背景图片 / Wallpaper:- 选择图片 / Choose image — pick a local image (≤ 2MB, stored as a data URL, kept in this browser only). Local video files are not uploaded; paste a URL instead.

  • 网址 / URL — paste http(s) / data image or video (mp4/webm/ogv/mov). blob is rejected (dies on reload). No extra media server.
  • 显示方式 / Fit — cover / contain / stretch / tile.
  • 界面遮罩 / UI wash and 模糊 / Blur sliders (rAF-coalesced; no crash). Higher wash = more solid UI.
  • 移除 / Remove clears it.

The wallpaper lives on a z-index: -1 fixed layer, so it is only visible through the translucent main canvas and sidebar; message surfaces keep their solid backgrounds for readability. It also follows your active skin's tint (switching skins re-shades the translucent surfaces).

奶龙桌宠 / Pet

In Settings → General → 奶龙桌宠 / Pet you can show/hide the pet, resize it (64–180 px) and reset its position. Behavior:

  • Status moods — the dragon follows the agent: thinking when a turn starts, working while it runs, done (with sparkles) when it finishes, then back to idle. Left idle too long it falls asleep (sleeping, Zzz).
  • Sticker pack (表情包) — hover the pet and open 🎨: 8 moods to pick (idle / happy / thinking / working / done / sad / surprised / sleeping). Clicking the pet also cycles to a random sticker for a few seconds.
  • Draggable — drag it anywhere; the position is remembered (dsh-skin:pet-pos). Reset it from the settings row.
  • Zero assets — every sticker is inline SVG (original hand-drawn art in a Nai-Long style, not the licensed character), so the bundle stays dependency- free and crisp at any size. preview.html in the repo shows the full pack.

Persistence

Choices are stored in localStorage (dsh-skin:skin, dsh-skin:wallpaper, dsh-skin:wallpaper-opacity, dsh-skin:wallpaper-blur, dsh-skin:wallpaper-fit, dsh-skin:pet-enabled, dsh-skin:pet-size, dsh-skin:pet-pos). DSH's Host settings wire only exposes an allowlisted set of namespaces to browser clients (WEB_SETTINGS_NAMESPACES in dsh-host-apiproxy), so a third-party namespace would answer settings-not-exposed; the product itself keeps remote browser preferences process-local, and localStorage matches that boundary for a visual preference while surviving reloads on the same origin.

Install

From anywhere, add the package to the web profile:

dsh plugin --profile web add -w /path/to/dsh-skin

The -w flag is required: every profile ships a pnpm-workspace.yaml, so pnpm 9 treats the profile directory as a workspace root and refuses a bare add with ERR_PNPM_ADDING_TO_ROOT.

This runs pnpm in ~/.dsh/profiles/web, installs the package, and appends it to dsh.profile.bundles (its patch layer inserts the skin loader entry). The running web server must be restarted to pick up the new bundle layer:

# stop the running instance, then:
dsh web

Open Settings → General to use the skins, wallpaper and pet.

Publishing (npm)

DSH (rc.6) has no separate plugin marketplace — the plugin distribution channel is the npm registry. A package that declares dsh.bundle (host patch layer) and dsh.client (browser bundle) is exactly what dsh plugin --profile <name> add <package> installs, so publishing this package to npm is what "上架" means today:

  1. Pick a unique name (scoped names are safer, e.g. @yourscope/dsh-skin) and fill in author, repository, keywords, and a CHANGELOG.
  2. Make sure files ships lib/index.js, lib/client.js, lib/types, cordis.patch.yml (already configured).
  3. Publish to the official npm registry (this machine's default registry is a mirror — publishing to a mirror does not reach npmjs):
    npm publish --registry https://registry.npmjs.org
  4. Users install with:
    dsh plugin --profile web add -w @yourscope/dsh-skin
    then restart dsh web.

Known platform boundaries to document for users: browser-side preferences are stored in localStorage (third-party settings namespaces are not exposed over the wire yet), and the client bundle may only require module-table entities (platform seeds + registered client bundles).

Development

The client bundle is written directly in the __ModuleLoader__ bundle format (the same shape tsdown emits for the shipped ui-* packages), so no build step is required. lib/client.js may require only module-table entities: platform seed words (react, react/jsx-runtime, …) and registered client bundles (@deepseek-ai/dsh-client-runtime/client, @deepseek-ai/dsh-client-ui-theme/client, …). After editing, restart the web server (bundle content is re-hashed and served with a new rev; loader entries are rescanned at boot).
