The core design principle of DeepSeek Harness is “everything is a plugin.” When using DSH for development or operations, customizing the interface appearance is a common need. dsh-cool-theme is a theme plugin that supports Dark / Light / System appearance switching, includes 34 built-in preset themes, and supports creating, sharing, and importing custom themes.

Plugin Overview

This plugin is maintained by CoolTea and is licensed under MIT. It addresses the limited interface appearance options and provides a one-stop theme management solution from presets to customization.
