  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by jihe520 on GitHub. Read the source before you install it.

Installation

Install the 2analysis Modeling AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/jihe520/MathModelAgent.git /tmp/MathModelAgent
mkdir -p .claude/skills
cp -r /tmp/MathModelAgent/skills/2analysis-modeling .claude/skills/2analysis-modeling
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable 2analysis Modeling in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads 2analysis Modeling on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so 2analysis Modeling is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

赛题分析与建模设计

数学建模规范参考

如需领域判断,读取 ../_references/math_modeling_norms.md 中的“赛题理解与子问题识别”“假设与模型建立”和“题型防错速查”小节。该文件只作为规范知识库,不替代本阶段的分析报告结构。

必须产出

在当前工作目录的 reports/ 子目录中创建或更新:

  • reports/ANALYSIS_MODELING_REPORT.md
    • 赛题分析、子问题拆解、数据与附件理解、评价标准、关键歧义和假设预检。
    • 变量、符号、模型假设、目标函数、约束条件、求解算法、各子问题实现口径、代码阶段任务清单

不要在本阶段写论文正文,不要生成最终 paper/,不要把图表排版任务提前到这里。

工作流程

Step 1: 子问题拆解

只把题面中明确编号的顶层问题当作子问题,例如“问题一/二/三”“Problem 1/2/3”。不要把小问、背景描述、数据说明、提交要求误当成独立子问题。

ANALYSIS_MODELING_REPORT.md 开头明确写:

根据题目动态调整问题数量

本赛题共 X 个子问题。

每个子问题要说明:

  • 输入数据和已知条件。
  • 决策变量或预测对象。
  • 目标函数或评价指标。
  • 约束条件。
  • 与其它子问题的依赖关系。
  • 绘制哪些图像或表格来展示结果。

Step 2: 假设敏感性预检

列出关键歧义,不要急着定模型。对影响结果的歧义至少给出两种解释,并用简单验算或逻辑递进判断选择。

必须在 ANALYSIS_MODELING_REPORT.md 中包含:

markdown
## 假设敏感性预检

### 模糊表述及解释
...

### 快速验算与递进性检查
...

### 最终采用的解释
...

### 绘制的图像和对比表格

如果某个假设会让后续问题的新增条件没有边际效果,要回头调整解释.

Step 3: 数据理解与建模路线

对每份附件做数据理解:

  • 行列规模和字段解释。
  • 缺失、异常、重复、单位不一致。
  • 可直接用于建模的变量。
  • 需要派生的指标。

然后给出总体路线:

text
题面 -> 数据清洗(EDA) -> 子问题一模型 -> 子问题二模型 -> 。。。。 -> 结果检验 -> 论文展示

Step 4: 建模报告

ANALYSIS_MODELING_REPORT.md 中写出可交给代码阶段实现的完整方案。

每个子问题至少包含:

  • 问题目标。
  • 符号和变量。
  • 模型假设。
  • 目标函数。
  • 约束条件。
  • 求解方法。
  • 输入输出。
  • 代码实现要点。
  • 结果校验方法。

公式要清楚到代码阶段能直接实现。算法描述要包含核心步骤、停止条件、复杂度或可行性说明。

推荐结构:

markdown
# 建模报告

## 1. 总体建模框架
## 2. 数据处理方案
## 3. 符号说明
## 4. 问题一模型
## 5. 问题二模型
## 6. 问题三模型
    .... 
## 7. 灵敏度分析与检验方案
## 8. 代码实现任务清单

如果子问题数量不是 3 个,按实际题面调整章节,不要硬凑。

Step 5: 给代码阶段的接口

ANALYSIS_MODELING_REPORT.md 末尾写一个“代码实现任务清单”,格式如下:

markdown
## 代码实现任务清单

| 任务 | 输入 | 输出 | 方法 | 校验 |
| --- | --- | --- | --- | --- |
| 问题一 | ... | ... | ... | ... |
| 问题二 | ... | ... | ... | ... |

质量要求

  • 所有结论都能回到题面或数据。
  • 不编造数据字段和数值。
  • 不跳过歧义分析。
  • 模型既要有数学表达,也要能被代码实现。
  • 若数据不足或题面不清,要明确记录风险和替代方案。

Frequently asked questions

What does the 2analysis Modeling AI skill do?

Why use 2analysis Modeling on TypingMind?

Because you install it once and use it with any model. 2analysis Modeling is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install 2analysis Modeling in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/jihe520/MathModelAgent/tree/main/skills/2analysis-modeling. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use 2analysis Modeling?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with 2analysis Modeling?

As many as you like. As long as a model supports skills, you can use 2analysis Modeling with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the 2analysis Modeling AI skill free?

It is published on GitHub by jihe520. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
