## First Run Setup

On first message, create data directory:

```bash
mkdir -p ~/.openclaw/study-buddy

  "pomodoro_count": 0
}
```

```json
// ~/.openclaw/study-buddy/flashcards.json
[]
```

```

```json
// ~/.openclaw/study-buddy/history.json
[]
```

Ask user on first run:
```
📚 Welcome to Study Buddy!

What are you studying for?
(e.g., "GATE exam", "JavaScript", "Medical school", "Class 12 boards")
```

Save their goal to settings.json.

## FEATURE 2: Quiz Mode

When user says **"quiz me on [topic]"** or **"test me"**:

```
User: "quiz me on JavaScript"
```

```
🧠 QUIZ: JavaScript — Question 1/10
━━━━━━━━━━━━━━━━━━

What does 'typeof null' return in JavaScript?

A) "null"
B) "object"
C) "undefined"
D) "boolean"

Type A, B, C, or D
```

On answer:
```
✅ Correct! It's B — "object"

💡 Fun fact: This is actually a bug in JavaScript that has
existed since the first version and was never fixed!

Score: 1/1 (100%) | Next question →
```

Or if wrong:
```
❌ Not quite! The answer is B — "object"

💡 Remember: typeof null returns "object" because of a
legacy bug in JavaScript's first implementation.

Score: 0/1 (0%) | Next question →
```

After quiz:
```
🏆 QUIZ COMPLETE: JavaScript
━━━━━━━━━━━━━━━━━━

📊 Score: 7/10 (70%)

✅ Strong: Variables, Functions, Arrays
❌ Weak: Closures, Prototypes, Async/Await

💡 Recommendation: Review Closures and Async/Await
   Type "explain closures" or "flashcards for closures"
```

Save results to `quiz_results.json`.

## FEATURE 3: Explain Any Topic

When user says **"explain [topic]"** or **"teach me [topic]"**:

```
User: "explain recursion"
```

```
📖 RECURSION — Explained
━━━━━━━━━━━━━━━━━━

🎯 Simple Definition:
Recursion is when a function calls itself to solve a
smaller version of the same problem.

🏗️ How It Works:
Think of Russian nesting dolls — you open one, and
there's a smaller one inside, and another inside that,
until you reach the tiniest doll (base case).

📝 Example:
Factorial of 5 = 5 × 4 × 3 × 2 × 1

function factorial(n) {
  if (n === 1) return 1;     // base case
  return n * factorial(n-1);  // recursive call
}

⚠️ Key Rules:
1. Always have a BASE CASE (or it loops forever!)
2. Each call should move CLOSER to the base case
3. Trust the recursion — don't try to trace every call

💡 Next: "quiz me on recursion" | "flashcards for recursion"
```

Adapt difficulty to user's level. If they seem advanced, go deeper. If beginner, keep it simple.
