## Core Principle

A high-efficiency learning methodology that integrates **First Principles Thinking**, **Taxonomy-Based Classification**, **Feynman Technique**, and **Recursive Questioning** into a closed-loop system:

1. **First Principles** → Trace to fundamental facts and concepts
2. **Classification** → Systematically decompose and structure
3. **Feynman Technique** → Validate through output, identify gaps
4. **Recursive Questioning** → Chase "aha moments" through layered inquiry

## Learning Flow (9 Steps)

When users mention learning, exam prep, or skill acquisition, guide them through this process:

### Step 1: Define Goals & Evaluation Criteria
- Clarify learning objectives (target proficiency level)
- Establish evaluation standards (how to measure mastery)
- Set timelines and milestones

### Step 2: Apply First Principles
- Break down problems to find fundamental facts
- Keep asking "why" until reaching irreducible truths
- Distinguish between assumptions and verified facts

### Step 3: Use Taxonomy-Based Classification
- Divide topics into distinct subtopics/categories
- Build classification systems (preferably MECE: Mutually Exclusive, Comprehensively Encompassing)
- Clarify relationships between categories

### Step 4: Apply Feynman Technique with Recursive Questioning

**Core Process (5 Sub-Steps)**:

#### 4.1 Start with a Real Problem
- Begin with concrete, practical challenge
- Example: "Write a diffusion model code" or "Implement this algorithm"
- Ground learning in tangible context

#### 4.2 Generate Questions Through Practice
- While working, note every confusion point
- Ask: "Why does this work?" "What does this term mean?"
- Record questions without immediately seeking answers

#### 4.3 Recursive Downward Questioning
- For each unclear concept, ask deeper questions
- Pattern: "What do you mean by X?" → "Why is X necessary?" → "What happens without X?"
- Continue until reaching intuitive understanding
- Example chain:
  - "What is 'gradient descent'?" →
  - "Why do we need to minimize loss?" →
  - "What is 'loss' actually measuring?" →
  - "Why is measuring error useful?" →
  - **Aha!** "Loss is just a compass pointing toward better answers"

#### 4.4 Restate in Your Own Words
- After each answer, rephrase to confirm understanding
- Use: "So my understanding is... Is this correct?"
- If explanation feels forced or unclear, return to 4.3
- Valid understanding = can explain to a 10-year-old

#### 4.5 Chase the "Aha!" Moments
- Recognize the click: "Oh! That's why!"
- These moments mark true comprehension milestones
- Document each aha moment with:
  - What was unclear before
  - What clicked
  - Why it matters
- **Key insight**: One deep aha > Ten shallow memorizations

### Step 5: Multi-Perspective Learning
- Use diverse resources (books/videos/courses/practical exercises)
- Cross-validate information across sources
- Find the optimal personal learning path

### Step 6: Practice & Application
- Select relevant projects for hands-on practice
- Analyze real-world case studies
- Connect theory with practical application
- Apply recursive questioning to new challenges

### Step 7: Feedback & Iteration
- Regular review of learned content
- Seek peer feedback (teach, question, evaluate)
- Adjust learning strategy based on insights
- Revisit aha moments to reinforce understanding

**📝 Exam Paper Generation** (NEW in v1.1.1):
```
🎯 Auto-generate exam questions based on learning content

Question types:
• Multiple Choice (3-5) - Concept understanding
• Fill in the Blank (3-5) - Key term memory
• Short Answer (2-3) - Logical expression
• Practical/Code (1-2) - Application ability

Each question includes: difficulty level, knowledge point, reference answer
```

### Step 8: Continuous Learning & Review
- Periodically revisit mastered content (spaced repetition)
- Follow Ebbinghaus Forgetting Curve for reviews
- Expand into related knowledge domains
- Apply recursive questioning to advanced topics

### Step 9: Mind Mapping & Notes
- Use mind mapping tools to organize knowledge structure
- Build systematic note-taking systems (Cornell Notes method)
- Maintain traceable and updatable notes
- **Special**: Create "Aha Moment Log" tracking breakthrough insights

## Trigger Scenarios

When users say (English):
- "I want to learn..."
- "How to learn efficiently..."
- "Is there a good learning method..."
- "Help me create a study plan..."
- "This concept is unclear..."
- "Want to systematically master..."
- "Why does this work?"
- "I don't understand..."

当用户说 (Chinese/中文):
- "我想学习..."
- "怎么高效学习？"
- "有什么好的学习方法？"
- "帮我制定学习计划..."
- "这个概念不清楚..."
- "想系统掌握..."
- "为什么是这样？"
- "我不懂..."

→ 主动推荐此学习方法 / Proactively recommend this method

## Multi-Language Response (Bilingual Support)

This skill supports **bilingual responses** based on user's language preference. The response language should match the user's input language.

### Language Detection Logic

| User Input Language | Response Language | Example Trigger |
|---------------------|-------------------|-----------------|
| English | English | "I want to learn machine learning" |
| 中文/Chinese | Chinese (中文) | "我想学习机器学习" |
| Mixed | Use dominant language | If majority is Chinese → Chinese |

### Response Template

**When user speaks English:**
```
# RootCraft Learning System

This is a high-efficiency learning methodology...

[English content following the 9-step flow]
```

**When user speaks Chinese:**
```
# 格物本质赋能学习法 (RootCraft Learning System)

这是一个融合第一性原理、分类学、费曼 technique 与递归追问的高效学习系统...

[中文内容，遵循 9 步流程]
```

### Key Bilingual Elements

| Element | English | Chinese |
|---------|---------|---------|
| Skill Name | RootCraft Learning System | 格物本质赋能学习法 |
| Core Concept | First Principles | 第一性原理 |
| Key Term | Aha Moment | 啊哈时刻 |
| Method | Feynman Technique | 费曼 technique |
| Framework | Taxonomy Classification | 分类学拆解 |
| Process | Recursive Questioning | 递归追问 |

### Practical Guidelines

1. **Detect language** from user's first message
2. **Switch language** only at conversation start, maintain consistency
3. **Bilingual output** for skill description sections (both languages)
4. **User guidance** always in user's detected language
5. **Technical terms** can remain in English (e.g., MECE, Feynman) with Chinese explanation

```

### Example Output / 示例输出

**Input / 输入**: topic = "梯度下降" / "gradient descent"

**Output / 输出**:

```
## 追问链：梯度下降 / Question Chain: Gradient Descent

### Q1: 什么是梯度下降？ / What is gradient descent?
**A1**: 梯度下降是一种优化算法，用来找到函数的最小值。就像下山时每一步都往最陡的下坡走。

### Q2: 为什么要用"梯度"？ / Why use "gradient"?
**A2**: 梯度指向函数上升最快的方向。反过来，沿着梯度的相反方向走，就是下降最快的方向。

### Q3: 为什么一定要"下降"？ / Why must it "descend"?
**A3**: 因为我们的目标是找到最小值（最优解）。下降是逼近最小值的方式。

### Q4: 如果不用梯度，还有什么方法？ / If not gradient, what else?
**A4**: 还有牛顿法（用二阶导数）、随机搜索、遗传算法等。但梯度下降是最简单高效的。

### Q5: 梯度下降的本质是什么？ / What's the essence of gradient descent?
**A5**: 梯度下降的本质是"贪心策略"——每一步都做当前最优选择，虽然不一定全局最优，但足够实用。

💡 **AHA MOMENT**:
梯度下降 = "每步都往下走一走"
本质 = 贪心算法在优化问题上的应用
比喻 = 像盲人下山，每步都摸一下坡度，往最陡的方向走
```

## Example: Learning Diffusion Models

### Step 1: Set Goals
- **Goal**: Understand and implement a basic diffusion model
- **Evaluation**: Can explain forward/reverse process and generate images
- **Time**: 2-3 weeks

### Step 2: First Principles
Diffusion essence = Gradual noise addition + Learned denoising
- Why add noise gradually?
- What does "learned denoising" mean?
- How does this connect to thermodynamics?

### Step 3: Taxonomy
```
Diffusion Models
├── Forward Process (noise scheduling)
├── Reverse Process (denoising network)
├── Training Objective (noise prediction)
├── Sampling (iterative denoising)
└── Applications (image generation, inpainting)
```

### Step 4: Recursive Questioning in Action

**Question Chain Example**:
```
Q: "Why do we add noise gradually?"
→ A: "To create a tractable path between data and noise"

Q: "What does 'tractable path' mean?"
→ A: "A path we can reverse mathematically"

Q: "Why do we need to reverse it?"
→ A: "Because generation = going from noise back to data"

Q: "Why start from noise at all?"
→ A: "Noise is easy to sample; data is hard to model directly"

💡 AHA! "Diffusion is like unscrambling an egg - we practice scrambling 
   so much we learn to unscramble!"
```

### Step 5: Multi-Perspective
- Paper: "Denoising Diffusion Probabilistic Models"
- Video: Lilian Weng's blog explanation
- Code: Hugging Face Diffusers library

### Step 6: Practice
- Implement simple 1D diffusion
- Use diffusers for 2D image generation
- Modify noise schedule and observe effects

### Step 7: Feedback
- Explain to colleague/peer
- Write blog post on understanding
- Compare with other generative models

### Step 8: Review
- Revisit aha moments weekly
- Connect to VAEs, GANs, flows
- Apply to new domains (audio, video)

### Step 9: Mind Map
```
Diffusion Models
├── Core Insight: "Learned unscrambling"
├── Forward: Data → Noise (easy)
├── Reverse: Noise → Data (learned)
└── Aha: "Practice destroying to learn creating"
