Can I change the theme of DeepSeek Harness?

Yes. Theme and skin plugins replace the look of the DSH web UI: dsh-deep-whale (whale-girl maid-atelier skins, light+dark), dsh-xiaoyao-skins, QQ2006 skin, and freestyle-dsh-theme (a theme designer with OKLCH palettes).

How do I install a DeepSeek Harness theme?

One command, e.g. 'dsh plugin add github:Small-tailqwq/dsh-deep-whale', then pick the skin in the theme/settings area of the web UI. Some skins need a page refresh.

Which theme plugin is the most popular?

dsh-deep-whale (the whale-girl maid-atelier series with light and dark previews) and whale-girl (a desktop pet skin) are the most talked-about in the community.

DeepSeek Harness Themes & Skins: Customize Your Interface

“How do I make DeepSeek Harness look different?” is one of the most common UI questions. The answer: theme and skin plugins. This guide covers the best ones in the Themes & Appearance category.

The short answer

The community’s favorite visual plugins:

dsh-deep-whale — the whale-girl maid-atelier skin series, with dedicated light and dark previews
whale-girl — a QQ-pet-style desktop companion that changes how the UI feels
dsh-xiaoyao-skins — the Xiaoyao × DSH skin collection with an installer
dsh-qq2006 — a full QQ2006 retro skin
freestyle-dsh-theme — a theme designer: propose OKLCH palettes, persists across restarts
dsh-gui-customization — palettes, ambient light and background presets
dsh-deepcel — an Excel-like layout, for spreadsheet people

Install and switch

dsh plugin add github:Small-tailqwq/dsh-deep-whale

After install, open the web UI, go to the theme/settings area, and pick the skin. Most skins take effect immediately or after a refresh. The whale-girl series includes separate light and dark previews so you can see what you’re getting before switching.

Picking by taste

Wants the community-famous look → dsh-deep-whale (maid-atelier light/dark)
Wants retro → dsh-qq2006
Wants to design their own palette → freestyle-dsh-theme (OKLCH designer)
Wants a desktop companion pet → whale-girl
Wants spreadsheet vibes → dsh-deepcel

Build your own

If nothing fits, the ecosystem supports DIY:

freestyle-dsh-theme lets you design and persist a custom OKLCH palette.
dsh-gui-customization provides presets (Nous blue, ambient light, backgrounds) as a starting point.
Skin plugins in the Themes category generally document how their assets are structured, so you can fork them.

UI Enhancements category — sidebars, panels and layout plugins beyond theming.
Just for Fun category — pets, stickers and games that change the vibe even more.

Bottom line

Theming is one click away: start with dsh-deep-whale for the signature look, or freestyle-dsh-theme if you want to design your own. Every theme plugin in this directory links its source so you can inspect (and remix) it safely.
