DeepSeek Harness Plugin: dsh-paper-reader — A Paper-Reading Companion Workspace

The DeepSeek Harness (dsh) plugin is an all-in-one tool for reference management, PDF reading, and AI-assisted reading. It provides a three-pane workspace that integrates a reference library, a reader, and native chat without altering the official interface. Core features include precise Q&A with page numbers and jumping to the original text, coach-style step-by-step guided reading, one-click Chinese translation (with formula repair), and reference management. Installation is supported via desktop and command line. After importing a PDF into the library, you can ask questions about selected text or switch to a Chinese-English bilingual mode with one click. The plugin is released under the MIT license and must be re-enabled after upgrades.
