dsh-yunoseek-skin is a web GUI plugin for DeepSeek Harness, maintained by clclyzyzybzjsq, version 0.2.0, MIT licensed, and requires Node.js 22+. The plugin aims to change the DSH browser-side visuals to the pink style of the yunoseek chat interface while overriding system prompt assembly. Core features include: 1) Pink theme layer, covering semantic and static tokens, supporting automatic light/dark mode switching; 2) Visual enhancement, recoloring Hero glow effects and adding avatars to the assistant row (relies on stable UI selectors); 3) Brand display, showing the yunoseek logo and welcome images in non-official builds, while retaining the original brand in official builds; 4) Identity prompt injection, enabled by default and taking effect globally.
