Individual skill

edu-math-video

Use when asked to make an explainer / walkthrough video (讲解视频、解题视频、板书视频、例题精讲、微课) for a math problem (数学题, geometry, algebra, functions, motion/行程 problems), from a problem screenshot or text, with Chinese voice-over — delivered as a browser preview (HTML) first, MP4 export only if the user wants it. Five visual templates — hand-drawn canvas animation (bilingual zh+en subtitles) or one of four board styles (粉笔黑板 chalk / 几何实验室 lab / 白板 whiteboard / 方格本 notebook, auto-rotating 3D figures) — and a choice of TTS engine (智谱 GLM-TTS, 豆包 Doubao, MiniMax, or free edge-tts / macOS say).

# 数学题讲解视频 (edu-math-video)

把一道数学题做成 16:9、1920×1080、带中文配音的讲解视频：**先生成能直接在浏览器里播放的网页预览，用户看过后再问要不要导出 MP4**。**五种画面模板、五种配音引擎可选**（配音在第 0 步定；板书风格自动选，预览页里可随时切换；只有导出 MP4 时才问用哪种风格）。

| 模板 | 画面 | 做法 | 适合 |
|---|---|---|---|
| `handdrawn` 手绘动画 | 手绘笔记本风 canvas 动画，中英双语字幕，背景音乐+音效 | 每题手写 `anim.js`，动作最自由（滑动重合、展开、拼接、动点） | 推理要靠"动"才看得懂的题、行程/动点、需要英文字幕 |
| `chalk` 粉笔黑板 | 黑板粉笔字、圈画强调、公式用 LaTeX（KaTeX）排版 | 写声明式 `lesson.json`，引擎自动排版 | 通用、老师讲题感 |
| `lab` 几何实验室 | 深色发光、步骤条、缓慢摆动的 3D 图 | 同上 | 高中立体几何、函数图像 |
| `whiteboard` 白板马克笔 | 白板、红色标签、便利贴提示 | 同上 | 初中 |
| `notebook` 方格本 | 方格纸、猫头鹰助教、印章 | 同上 | 小学、初一 |

四种板书模板共用 `lesson/` 引擎（同一份 lesson.json 随时切换风格），立体图自动旋转并实时计算虚实线。**板书模板比手绘快得多**（写几百行 JSON，而不是从零写动画），是默认推荐。
