xiaozhi-math-concept-explainer skillA
xiaozhi-math-concept-explainer is agent-read markdown (skill) from qizhitang/xiaozhi-skills: 初中数学概念的理解与重建：学生不是卡在某道题，而是卡在"这个数学概念本身没懂"时用。 典型触发："这个数学公式我知道但不明白为什么""负负为什么得正""一次函数和正比例有什么区别""几何题我脑子里建不起图形""这两个数学概念我总是混""用生活例子讲讲这个概念"。 核心方法：三种解释模型（生活类比 / 图解可视化 / 逐步拆分）+ 几何空间想象训练。 不处理：具体某道题怎么做（转 xiaozhi-math-problem-solving-coach）、应用题列式（转 xiaozhi-math-word-problem-coach）、错题收录与统计（转 xiaozhi-correction-notebook）、分层进阶练习（转 xiaozhi-math-gradient-trainer）。.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add qizhitang/xiaozhi-skills/xiaozhi-math-concept-explainer@v2.1.10mdr add qizhitang/xiaozhi-skills/xiaozhi-math-concept-explainer@sha256:54aa687aea7bf068Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
