An unofficial Claude-inspired light/dark theme for DeepSeek Harness with responsive layout, safe Markdown preview, and zero telemetry.
The plugin will be installed here. Keep web if you are unsure.
npx -y @deepseek-ai/dsh plugin --profile web add github:ZJUZhiyuCai/dsh-ivory#ecb4b4c2680b2261137f421ccbb72f946fee4dba
Compatibility and provenance
Ivory is published as dsh-ivory and currently resolves to version 0.2.12. The Hub verifies its manifest and preserves the exact installation source for reproducible installs.
Ivory gives the DSH web interface a quieter reading rhythm without changing how
the harness works. Warm neutrals replace cold grays, editorial type improves
long responses, and the conversation stays usable from a narrow phone window
to a wide desktop. DeepSeek branding and every native DSH capability remain in
place.
Quick start
dsh plugin --profile web add dsh-ivory
dsh web
Hard-refresh the page with Cmd/Ctrl + Shift + R, then open
Settings → Ivory Theme. The main theme is enabled by default; the optional
focus mode stays off until you choose it.
Pin a release or uninstall
Install the exact GitHub release without using npm.
dsh plugin --profile web add github:ZJUZhiyuCai/dsh-ivory#v0.2.12
Remove Ivory and return to the native DSH interface.
dsh plugin --profile web remove dsh-ivory
Made for everyday DSH
Area
What Ivory changes
Appearance
A complete warm-neutral palette for light and dark mode, with restrained shadows, corners, and editorial typography.
Responsive layout
Host-adaptive, drag-resizable conversation geometry tested at 375, 768, 1,440, and 1,920 pixels.
Reading and copying
Independent controls for prose, user bubbles, and code blocks, plus a small end-of-response marker.
Markdown documents
A bounded, DOM-built preview for .md output with source view always available and HTTP(S)-only links.
Accessibility
Keyboard focus, reduced-motion behavior, forced-colors fallbacks, and WCAG AA muted text contrast.
Compatibility
Structural styling degrades to stable theme tokens when the verified DSH selector contract changes.
[!NOTE]
DeepSeek Harness is in developer preview and may make breaking UI changes.
Ivory 0.2.12 is verified against DSH 0.1.2-rc.1 through 0.1.5 and its current
web client modules. When Ivory cannot prove the current structural contract,
it keeps token-level theming and releases the host layout back to DSH.
Quality and release checks
npm ci
npm test # renderer unit tests, then the static release gates, build, publint, and package checks
npm run qa:r2 # 74 browser regressions; DSH must run at 127.0.0.1:3080
npm run qa:adversarial # 33 stress checks: reconciliation safety, toggle/resize storms, degraded mode
npm run qa:activity # 26 checks for thinking/tool-call rows, icons, and terminal polish
npm run qa:micro # 28 Vision Toolkit/Ivory micro-component checks; set DVT_CLIENT_JS if the toolkit is not installed in the DSH web profile
npm run qa:host # 10 checks against the live host: contract health, sidebar/composer/settings surfaces, both themes
npm run qa:contract # diagnostic probe (no pass/fail): self-diagnosis channel plus a live selector inventory
The last two need DSH_QA_TOKEN from the dsh web URL. Every QA entry point in
package.json is documented here, and a release check fails if one goes missing.
The browser suite covers responsive layout, composer focus, dark mode,
Markdown injection attempts, streaming state, lifecycle cleanup, block-copy
payloads, plugin coexistence, long tables, reduced motion, and forced colors.
Releases use npm Trusted Publisher with GitHub OIDC. The repository stores no
long-lived npm publish token, and future CI releases receive npm provenance
automatically.
Development
npm ci
npm run build
dsh plugin --profile web add link:$PWD
dsh web
Edit src/skin.css, src/client.template.js, or src/markdown.js, then run npm run build.
The generated lib/client.js is committed so GitHub installs need no build
permission.
