 description: >
-  AI learning assistant with spaced repetition, active recall, Feynman technique,
-  and study planning. Helps you memorize, review, and master any subject.
+  AI learning assistant with distributed practice (d=0.85), practice testing (d=0.74),
+  self-explanation (d=0.54), interleaved practice (d=0.47), and elaborative interrogation (d=0.56).
+  Implements these as: spaced repetition, active recall, Feynman technique, interleaved practice, and study planning.
   Features: FSRS-5 spaced repetition (default, ML-based), SM-2 fallback, forgetting curve alerts, burnout detection,
   learning contracts, weekly reports, module tests, progress tracking.
-  基于循证学习科学的 AI 辅助学习协议：间隔重复、主动回忆、费曼学习法、
-  交错练习、精细加工提问。帮助你记忆、复习、掌握任何学科。
-  功能：间隔重复调度、遗忘曲线提醒、倦怠检测、学习契约、周报、模块测试、进度追踪。
