Study Companion: Running Planning, Practice, Testing, and Review in DSH

Study Companion is a DeepSeek Harness workflow plugin maintained by zgdllt, organizing AI conversations into a closed loop comprising planning, practice, testing, feedback, and review. The sidebar provides five tabs: Overview, Ladder, Exam Hall, Classroom, and Methods. The Host tool reads and writes local learning records, while conducting and grading one-question exams within the conversation. It is recommended to install via `git+https://github.com/zgdllt/study-companion.git#v1.0.0` and has been verified on DSH 0.2.1-rc.5. An optional macOS Safari adapter is available to synchronize YuKetang replays; archives are stored in `DSH_HOME/storages/study-companion/` and the project is MIT-licensed.
