dsh-chat-plus: DeepSeek Harness Enhanced Chat Experience Suite

dsh-chat-plus is an experience-enhancement plugin for DeepSeek Harness that achieves zero source-code modifications through the Cordis mechanism. Its core features include: a dual-pane Seeker execution dashboard displaying tasks, actions, sub-agents, and artifacts; in-content interactive cards supporting HTML sandbox previews and 16 native interactive components; and a sidebar integrated with six major workbenches: Memory, Soul, Capabilities, Usage, Gallery, and Mailbox. This plugin enhances information density and interactivity, supporting auto-layout, state persistence, and secure sandbox execution, significantly improving both development and usage experience.
