What it does
Edu Chem Reaction is an agent skill from wy51ai/edulab. 把一个化学反应做成自包含的微观 3D 交互演示网页：左/上为 Three.js 可交互分子动画 （拖滑块看断键·成键·原子重组，分步高亮），右为 KaTeX 反应方程 + 分步讲解 + 原子守恒计数 + 可选能量-反应进程曲线。支持三入口——给定文字反应/方程、随机出题、上传图片识别后演示。 覆盖燃烧、化合/分解/置换/复分解、氧化还原（电子转移可视化）、有机机理（酯化等含催化剂·过渡态）。 统一由 sympy 精确驱动：自动配平方程、校验原子守恒与原子映射、推导键的断/成，答案与几何同源一致。 内置两套引擎并自动选择：morph（原子变形，展示原子守恒）与 mechanism（机理关键帧，展示催化/过渡态）。 混合几何：默认自建 VSEPR 分子库，环境装有 RDKit 则可用其由 SMILES 生成构象（绝不自动安装）。 其他 agent 也可调用本技能生成此类网页。形态与 edu-solid-geometry / edu-analytic-geometry 平行， 但用 Three.js + KaTeX 演示分子反应。 触发词：化学反应, 微观演示, 分子动画, 燃烧, 甲烷燃烧, 氢气燃烧, 电解水, 氧化还原…
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts and reference files (for example `lib/molecules.py`, `lib/reaction_kernel.py` and `references/conventions.md`).
It sits in Research & Science, covering Drug discovery and cheminformatics, Math and symbolic computation and 3D graphics and WebGL. It works with SymPy, Three.js, RDKit and Python. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Drug discovery and cheminformatics
- Tasks that involve Math and symbolic computation
- Tasks that involve 3D graphics and WebGL
Example prompts
- “/edu-chem-reaction”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 6a9c876. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Edu Chem Reaction loads about 1.2k tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 211 tokens; SKILL.md has 234 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- 把一个化学反应做成自包含的微观 3D 交互演示网页：左/上为 Three.js 可交互分子动画 （拖滑块看断键·成键·原子重组，分步高亮），右为 KaTeX 反应方程 + 分步讲解 + 原子守恒计数 + 可选能量-反应进程曲线。支持三入口——给定文字反应/方程、随机出题、上传图片识别后演示。 覆盖燃烧、化合/分解/置换/复分解、氧化还原（电子转移可视化）、有机机理（酯化等含催化剂·过渡态）。 统一由 sympy 精确驱动：自动配平方程、校验原子守恒与原子映射、推导键的断/成，答案与几何同源一致。 内置两套引擎并自动选择：morph（原子变形，展示原子守恒）与 mechanism（机理关键帧，展示催化/过渡态）。 混合几何：默认自建 VSEPR 分子库，环境装有 RDKit 则可用其由 SMILES 生成构象（绝不自动安装）。 其他 agent 也可调用本技能生成此类网页。形态与 edu-solid-geometry / edu-analytic-geometry 平行， 但用 Three.js + KaTeX 演示分子反应。 触发词：化学反应, 微观演示, 分子动画, 燃烧, 甲烷燃烧, 氢气燃烧, 电解水, 氧化还原, 电子转移, 酯化反应, 反应机理, 断键成键, 原子守恒, 质量守恒, 化学方程式配平, 解这个化学反应, 随机出一个化学反应, 这张图里的化学反应; chemistry reaction, microscopic/molecular animation, combustion, electrolysis, redox electron transfer, esterification mechanism, bond breaking and forming, atom conservation, balance equation, interactive chemistry reaction page.

这个技能产出什么
一个可直接用浏览器打开的单页 HTML：一侧是反应对应的 3D 分子动画（Three.js，可旋转缩放，
拖动“反应进度”滑块逐帧看 化学键断裂/生成、原子重新组合，分步高亮 + 浮动分子标签），
另一侧是 KaTeX 反应方程 + 分步讲解 + 原子守恒计数器，并可选 能量-反应进程曲线、
火焰、催化剂质子、电子转移等叠加层。形态与 template/reaction.html 一致。
依赖（重要）
计算核心 lib/reaction_kernel.py 依赖 sympy（用于配平）。运行脚本前先确认有一个能 import
sympy 的 python3：跑 python3 -c "import sympy"（本机：/opt/homebrew/bin/python3.11）。
缺库时的处理（重要）：若 import 报错（sympy 或后续用到的任何库都同理），先询问用户是否安装，
同意后再装（python3 -m pip install <库名>）或换解释器；不要未经询问直接装。
RDKit 是可选项：装了则混合几何会用它由 SMILES 生成真实构象，没装就用自建 VSEPR 库——
两种都能跑，本技能任何时候都不会自动安装 RDKit。
工作流程
第 1 步：得到 reaction spec（三入口归一）
把反应整理成结构化 spec（格式见 references/problem-schema.md）：反应物/产物、原子映射或显式原子、
条件（点燃/通电/催化/可逆）、所属类别、分步讲解、语言。
- 文字反应/方程：直接抽取反应物与产物，调 kernel 自动配平。
- 图片：用视觉读图抽取方程，并把识别到的反应回显给用户确认（方程/条件/类别/语言）后再继续。
- 随机出题：从注册表挑一个反应，或在库内物种间组合并用
balanced_coefficients配平、答案规整再用。
输出语言跟随提示词语言：英文提示 → 英文网页，中文 → 中文。spec 里记下
meta.language。
第 2 步：用 kernel 精确计算（不要心算）
按 references/conventions.md 的建模约定，调用 lib/reaction_kernel.py：
balanced_coefficients(...)用 sympy 零空间自动配平（方程系数有保证）；assemble_data(spec)展开分子实例、校验原子守恒与原子映射双射、推导键的断/成（差集）、 算出每个原子在反应物态/产物态的世界坐标，产出注入模板的data。
可先命令行自检：
python3 lib/reaction_kernel.py # 配平 + 守恒 + 键差 自检
python3 lib/molecules.py # 分子库自检第 3 步：写 build_* 拼 spec 并注入模板
📍 输出位置（重要）：成品 HTML 一律写到用户当前工作目录（
Path.cwd()），除非用户显式指定路径。 绝不要写进技能自身目录（skills/edu-chem-reaction/output/等）——那是技能内部的开发样例目录。
照着 scripts/generate.py 里的 build_* 改即可，再 render_html(K.assemble_data(spec), out)：
from pathlib import Path
out = Path.cwd() / "reaction-<反应简述>.html" # 落在用户当前目录
render_html(K.assemble_data(spec), out)范例（直接照抄改）：
build_combustion_ch4（甲烷燃烧·morph·火焰·能量）——高层species + atom_map的范本；build_redox_na_cl2（钠+氯气·氧化还原·电子转移）——叠加electrons；build_esterification（酯化·mechanism·催化剂·过渡态）——低层atoms + fragments + 关键帧的范本。
generate.py 可直接出已注册反应；不传路径默认写到 cwd：
python3 <技能目录>/scripts/generate.py combustion_ch4 ./reaction.html
python3 <技能目录>/scripts/generate.py list第 4 步：自检（对应正确性方案）
- sympy 配平系数 == 方程展示系数 == 各分子实例个数（
assemble_data内已断言）。 - 原子映射是反应物↔产物原子的双射、元素一致；键端点都存在（kernel 已校验）。
- 原子守恒计数器在反应前后不变（催化剂不计入）。
- 起本地静态服务（服务输出文件所在目录）用预览检查：无控制台报错、KaTeX 方程渲染正常、 拖滑块时断键/成键高亮与分步讲解一致。
⚠️ 必须关闭你开过的端口/服务：预览检查一结束就立即停掉本地服务，绝不留下占用端口的进程。 用 preview 工具开的：检查完马上
preview_stop。交付前确认端口已释放，再告诉用户结果。
第 5 步：交付
成品写在用户当前工作目录（cwd），命名形如 reaction-<反应简述>.html，把路径告诉用户，可直接浏览器打开。
交付前确认：(1) 成品在 cwd、不在技能目录；(2) 没有遗留任何由本次预览开启的本地服务/端口。
两套引擎与自动选择
模板内置一套统一渲染器、两种逐帧定位（共用键差绘制/标签/叠加层/UI）：
- morph（原子变形）：原子各自从反应物态插值到产物态，天然展示原子守恒/重组，适配任意反应。
- mechanism（机理关键帧）：原子归属刚体片段（fragment），按 K0/K1/K2 关键帧整体位移， 基团不变形，适配催化剂/过渡态/离去基团类有机机理。
assemble_data 据 meta.engine（auto/morph/mechanism）选择：auto 时，类别为 organic
或带 fragments 走 mechanism，否则走 morph。叠加层均为数据开关（见 schema）：
flame（燃烧/强放热）、catalyst（催化剂质子+开关）、transitionGlow（过渡态能量光）、
electrons（氧化还原电子转移）、energy（能量-反应进程曲线）、原子守恒计数器（默认开）。
配色：整体为亮色（教科书球棍图风：原子带深色描边 + 柔和投影 + 白底面板），各反应用 meta.accent
区分强调色（燃烧 amber、酯化 indigo、钠氯 violet…）。
扩展
- 加反应：在
generate.py加一个build_*（高层species+atom_map，或低层atoms+fragments）， 注册进REGISTRY。 - 加分子/离子：在
lib/molecules.py的_LIBRARY_BUILDERS加一项（VSEPR 几何 + 显示元数据 + 内部键）。 - 加叠加层：在
template/reaction.html增一个由data字段驱动的可选模块。

To copy it by hand, put the folder in .cursor/skills/edu-chem-reaction, .gemini/skills/edu-chem-reaction, .github/skills/edu-chem-reaction and .opencode/skills/edu-chem-reaction in your project.
What does Edu Chem Reaction need to run?
Going by SKILL.md and its folder, Edu Chem Reaction needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.
Does Edu Chem Reaction access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Edu Chem Reaction safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
