## 📋 CODE ANALYSIS:
- File Type: ${analysis.fileType}
- Complexity: ${analysis.complexity}
- Issues: ${analysis.issues.join(', ')}

## 🔧 FIXING RULES:
1. **Fix ONLY the specific errors mentioned above**
2. **Keep everything else unchanged**
3. **Ensure all text is wrapped in <Text> components**
4. **Replace ALL onClick with onPress**
5. **Replace ALL className with style={styles.name}**
6. **Add proper React Native imports**

## 📝 CODE TO FIX:
\`\`\`javascript

## 📋 ANALYSIS RESULTS:
- File Type: ${analysis.fileType}
- Complexity: ${analysis.complexity}
- Has JSX: ${analysis.hasJSX}
- Issues to fix: ${analysis.issues.length}

## 🎯 CONVERSION REQUIREMENTS:

### CRITICAL RULES:
1. **ALL text must be in <Text> components** - React Native requirement
2. **Use onPress instead of onClick** - Mobile interaction
3. **Use style prop with StyleSheet** - No className
4. **Add proper imports** - All React Native components
5. **Mobile-first design** - Touch-friendly, responsive

### TRANSFORMATIONS:
- \`<div>\` → \`<View>\`
- \`<span>\`, \`<p>\`, \`<h1-6>\` → \`<Text>\`
- \`<button>\` → \`<TouchableOpacity>\` + \`<Text>\`
- \`<input>\` → \`<TextInput>\`
- \`onClick\` → \`onPress\`
- \`className\` → \`style={styles.name}\`

### SCREEN REQUIREMENTS:
- Wrap in SafeAreaView for mobile layout
- Use ScrollView for scrollable content
- Add navigation hooks if needed

## 📝 SOURCE CODE:
\`\`\`javascript

## 🎯 OUTPUT:
Complete React Native ${analysis.fileType} with:
1. Proper imports
2. Converted JSX
3. Complete StyleSheet
4. Mobile-optimized design
