dsh-claude-harness

One package for the whole "make DeepSeek Harness look like Claude" job on macOS.

Piece	Delivered by
Claude Code style UI	dsh-claude-style (declared dependency; installed together)
Claude app icon	this package — assets/Claude.icns → Contents/Resources/icon.icns
App name "Claude Harness"	this package — CFBundleName / CFBundleDisplayName + the .app filename

Loading the plugin never changes the app by itself. Branding is opt-in (apply), because a half-applied code signature is what makes macOS kill the app on launch.

Install

Into a DSH profile — from GitHub:

cd ~/.dsh/profiles/desktop          # or your profile dir
npm install "github:Yesyugao/dsh-claude-harness" dsh-claude-style

or from a local checkout:

npm install "link:/path/to/dsh-claude-harness" dsh-claude-style

Then add both ids to dsh.profile.bundles in the profile's package.json:

{ "dsh": { "profile": { "bundles": ["...", "dsh-claude-style", "dsh-claude-harness"] } } }

Restart the app afterwards — plugin rows are read at startup.

Use

dsh-claude-harness status            # what the bundle looks like right now
dsh-claude-harness apply             # icon + name, re-sign, rename (idempotent)
dsh-claude-harness restore           # put the original icon/name back
dsh-claude-harness apply --app /Applications/DeepSeek\ Harness.app --json

The same three operations are on the local web server, so the app can call them:

GET  /dsh-claude-harness/status
POST /dsh-claude-harness/apply
POST /dsh-claude-harness/restore

Run dsh-claude-harness apply again after every app update: an update replaces the bundle, so the icon and the name come back as DeepSeek.

What apply does, in order

1. refuses anything whose CFBundleIdentifier is not com.deepseek.dsh;
2. backs up Info.plist + icon.icns to ~/.dsh/dsh-claude-harness/backup/;
3. installs assets/Claude.icns;
4. sets CFBundleName / CFBundleDisplayName to Claude Harness;
5. re-signs ad-hoc, top level only (codesign --force --sign -; --deep fails on the running helper subcomponents with "Operation not permitted");
6. renames the bundle to Claude Harness.app last, then refreshes LaunchServices and verifies codesign --verify passes.

Steps 3–5 are skipped when the values already match, so re-running is cheap.

中文衬线体

dsh-claude-style 的衬线字体栈以 "Anthropic Serif Web Text","Claude Style Noto Serif" 开头，但这两个族名都没有汉字字形（插件自带的 Noto Serif 是 802 字形的拉丁子集），所以汉字会一路回退到栈尾的 "Noto Sans SC","PingFang SC" —— 衬线标题里的中文全成了黑体。

插件的浏览器半边（lib/client.js，随本包一起加载）给栈里第一个族名补了一个只覆盖汉字的 @font-face：

@font-face{font-family:"Anthropic Serif Web Text";
  src:local("Songti SC"),local("Noto Serif SC"),local("Source Han Serif SC");
  unicode-range:U+3000-303F,U+3400-4DBF,U+4E00-9FFF,U+F900-FAFF,U+FF00-FFEF,U+20000-2FA1F}

汉字走系统宋体，拉丁字母仍由 Anthropic Serif 出图，两边互不打扰。不装 Anthropic 字体也照样生效（栈里第一个族名没有可用字形时，浏览器继续找同族的下一张 face）。

Notes

• macOS only (os: ["darwin"]), Node ≥ 22.6.
• 字体设置选「跟随宿主」时字体栈只有 --dsw-font-family（无衬线），中文衬线体补丁不介入。
• Ad-hoc re-signing resets TCC grants; macOS may ask again for folder access.
• restore puts back the plist/icon/name from the backup, not a different app version.
• The icon: 1024×1024 squircle, #D97757, with the Claude mark centred by pixel centroid. Source assets/icon.html → assets/Claude.icns.
• Check: npm test — test/branding.test.mjs builds a throwaway fake bundle and exercises apply → no-op → restore against the real codesign; test/routes.test.mjs drives the HTTP handler with a mock request/response; test/client.test.mjs runs the browser half against a minimal DOM stub.
