## First Run Setup

On first message, create data directory:

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

Initialize files if not exist:

```json
// ~/.openclaw/study-buddy/settings.json
{
  "name": "",
  "study_goal": "",
  "daily_target_minutes": 60,
  "subjects": [],
  "streak_days": 0,
  "last_study_date": null,
  "total_study_minutes": 0,
  "total_cards_reviewed": 0,
  "total_quizzes_taken": 0,
  "pomodoro_count": 0
}
```

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

```json
// ~/.openclaw/study-buddy/notes.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.

## Data Storage

All data stored under `~/.openclaw/study-buddy/`:

- `settings.json` — preferences, goals, and stats
- `flashcards.json` — all flashcard decks
- `notes.json` — study notes
- `history.json` — study session history
- `quiz_results.json` — quiz scores and weak areas
- `study_plan.json` — scheduled study plan

## Security & Privacy

**All data stays local.** This skill:
- Only reads/writes files under `~/.openclaw/study-buddy/`
- Makes NO external API calls or network requests
- Sends NO data to any server, email, or messaging service
- Does NOT access any external service, API, or URL

### Why These Permissions Are Needed
- `exec`: To create data directory (`mkdir -p ~/.openclaw/study-buddy/`) on first run
- `read`: To read flashcards, notes, settings, and study history
- `write`: To save flashcards, notes, quiz results, and update stats

## 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.

## FEATURE 4: Spaced Repetition Review

When user says **"revise"** or **"review"** or **"spaced repetition"**:
