DeepSeek Harness Education Mode Plugin (dsh-edu-mode)

The `dsh-edu-mode` educational mode plugin for DeepSeek Harness (DSH) aims to transform agent deliverables from text into “understanding of the subject.” It enforces protocol-driven sessions covering five stages: collecting authoritative sources, step-by-step explanations, drafting class notes, quiz grading, and progress tracking. The plugin provides three core tools—`edu_course`, `edu_notes`, and `edu_quiz`—to manage course outlines, notes, and quizzes. It must be installed and configured via npm or similar methods, can be started with the `/edu` command and a specified course, and persists data in the workspace, delivering a structured, interactive teaching experience.
