Catppuccin for DeepSeek Harness

🌻 Latte

🪴 Frappé

🌺 Macchiato

🌿 Mocha

Features

• Complete, full Catppuccin colors — every color is a Catppuccin palette color; the default DeepSeek blue-gray never shows through.
• Classic mauve brand — the brand color follows the Catppuccin way: mauve, not the built-in blue.
• Your choice is remembered — the selected flavor persists per browser in localStorage and is re-applied at startup, even when the host re-asserts its own preference.
• Component-level accents — beyond tokens, message bubbles, tool-call rows, code block tags, timestamps, the homepage headline and hover states are tinted from the palette, with a gradient headline on the empty workspace.
• Zero intrusion on Default — switching back to the built-in appearance restores it pixel-identical; no injected styles remain.
• Four flavors, dark and light — Latte is tuned separately from the dark flavors, so each flavor looks balanced on its own surface.
• Palette-pure — every value is a Catppuccin palette color or a mix of palette colors; nothing from outside the family.

Usage

This is a dual-face theme plugin for DeepSeek Harness (dsh). It registers the four Catppuccin flavors into the built-in theme runtime, so they appear as selectable skins in Settings → General → Catppuccin theme.

Install

From a GitHub repository:

dsh plugin --profile web add github:zhijun-dai/Catppuccin-dsh-theme

From a local checkout (the -w flag is required — the profile directory is a pnpm workspace root):

dsh plugin --profile web add -w /path/to/Catppuccin-dsh-theme

From npm:

dsh plugin --profile web add dsh-catppuccin

The npm release may lag behind. For the latest version, use the GitHub install method above (a branch can be pinned with #branch-name).

Restart the web server afterwards:

dsh web

Switch themes

Open the web UI, go to Settings → General, and pick one of the four Catppuccin flavors (or Default to follow the built-in appearance). The choice is stored per-browser in localStorage.

How it works

The theme definitions are generated from the official catppuccin/palette palette.json (never hand-edited). scripts/gen-themes.mjs maps the 26 Catppuccin colors per flavor onto the --dsw-alias-* token directory from dsh's @deepseek-ai/dsh-client-ui-theme stylesheets (including the --shiki-* syntax palette and the leaked --dsw-static-deepseek-* static colors), writes the per-flavor token tables to themes/, and embeds them into the browser bundle lib/client.js.

node scripts/gen-themes.mjs
