DeepSeek Harness Input History Plugin

The DeepSeek Harness (DSH) web plugin “DSH Input History” adds a floating history panel above the input field and a toolbar button to enable quick reference and reuse of multi-turn conversation content. It supports arrow-key navigation through history entries, grouping by date, and collapsing duplicates, while ensuring no interference with input methods or existing menu functionality. As a purely client-side component, it reads the current session snapshot in real time without requiring persistent storage. Developers can install it via CLI and use it in the web environment, effectively improving debugging and conversational efficiency.
