explain skillA
explain is agent-read markdown (skill) from verymath/verymath-textbook-copilot: 根据当前教材解释概念、公式、推导与应用，回应学生的理解困难；用于讲解内容、解释原因、补全步骤和比较易混概念。.
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.
What the file says
# 教材讲解 先从问题和实际作答判断学生卡在含义、推理步骤、适用条件还是应用方法。信息足够就直接讲解，不先做固定的背景问卷。具体讲法按需读取 [针对卡点讲解](references/teaching.md)。 - 先使用本轮正文、实际历史及已有按页解析，内容不足或存在疑点时补读对应原页。避免为了小追问重新解析整节；需要图像校对的公式应对照原页。引用可核实的 PDF 页码。 - 先回答当前问题，再解释关键原因。概念问题用直观含义和恰当例子连接正式定义；推导问题补足中间步骤并说明所用条件；比较问题明确相同点和决定性差别；解题问题解释为什么选这个方法。 - 沿用教材符号，第一次使用新增符号时说明含义。自构例子与教材原例分开，检查边界、可行性和结论成立的条件。数值例子先算清楚再写进资料。 - 几何关系、变化规律和算法过程需要时配实际图形。由 Agent 根据自身实际可调用的 API 和工具选择方式，有文生图能力时优先使用，否则程序绘图；如实说明生成失败，不把程序绘图说成文生图。图像应能解释一个具体问题，公式、方向、比例与正文一致。只能提供示意图时明确标注。 - 承接追问时从卡住的那一步接着讲，不重新复述整份笔记。学生要求提示时只给下一步线索；展示实际作答时先找第一个影响结论的错误，再解释原因并给修正方法。需要补练时围绕这个错误调用已有出题能力，不凭一次回答推断全面掌握程度。 首次完整讲解默认保存为 markdown 学习资料。针对一句话、一个符号或某一步的小追问直接在对话中回答；用户明确要求保存、整理成笔记或修改资料时再写文件。讲解以解决当前问题为止，不机械套齐“定义—例子—证明—练习”的所有步骤。 需要保存时，按照本轮指定的结果路径和 ID 写入展示资料，同时在 outputs 保存可下载的 .md 正文。公式只生成一次，由前端提供源码复制。回复概括讲清了什么并引导查看资料。再次修改时围绕用户指明的部分调整，不无故重写整份内容。

How to install
mdr add verymath/verymath-textbook-copilot/explain@git:20260911.7bee855mdr add verymath/verymath-textbook-copilot/explain@sha256:05930f706eea3678Pin 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.
