| IMPORTANT: Provide the entire response in ${languageName}. All explanations, headings, and content should be in ${languageName}. | |
| CRITICAL INSTRUCTION: DO NOT include any code snippets, code blocks, or actual code in your response. Provide ONLY descriptive explanations in natural language. Instead of showing code, describe what the code does in detail using words only. | |
| USER DETAILS: | |
| ${languageContext} | |
| Explanation Level: ${explanationLevel} | |
| Response Language: ${languageName} | |
| CODE TO EXPLAIN: | |
| <<<BEGIN CODE>>> | |
| ${codeInput} | |
| <<<END CODE>>> | |
| Provide a comprehensive, well-structured explanation using section headers with underlines (not numbered lists). Format your response with clear section headers followed by detailed paragraphs. Use this structure: | |
| **Section Header Format**: Use descriptive section titles that explain what will be discussed, followed by detailed paragraphs. | |
| Structure your explanation with these types of sections: | |
| **Code Overview Section** | |
| - What this code does in simple terms | |
| - The main purpose and functionality | |
| - What problem it solves or what task it accomplishes | |
| **Detailed Analysis Section** | |
| - Describe each section and component in detail using natural language | |
| - Explain what each part does and why it's needed without showing the actual code | |
| - Describe how different parts work together | |
| **Key Concepts Section** | |
| - Important programming concepts demonstrated in this code | |
| - Explain any algorithms, data structures, or design patterns used | |
| - Define technical terms in simple language | |
| **Execution Flow Section** | |
| - Step-by-step execution flow described in words | |
| - What happens when the code runs | |
| - Input and output explanation | |
| **Learning Insights Section** | |
| - What beginners can learn from this code | |
| - Best practices demonstrated | |
| - Common patterns or techniques shown | |
| **Practical Applications Section** | |
| - Where this type of code might be used | |
| - Real-world scenarios and examples | |
| - How it could be modified or extended | |
| FORMATTING INSTRUCTIONS: | |
| - Use descriptive section headers (not numbered lists like 1., 2., 3.) | |
| - Write each section as flowing paragraphs of text | |
| - Ensure proper text direction for RTL languages | |
| - Integrate English technical terms naturally within the text flow | |
| - Use clear, professional formatting with proper spacing | |
| Tailor your explanation to the ${explanationLevel} level: | |
| - **Complete Beginner**: Use very simple language, explain basic concepts, avoid jargon | |
| - **Beginner**: Use clear language, explain intermediate concepts, minimal jargon with definitions | |
| - **Intermediate**: Use standard programming terminology, focus on logic and structure | |
| - **Advanced**: Use technical language, focus on optimization, patterns, and best practices | |
| Make the explanation engaging, educational, and easy to follow. Use examples and analogies when helpful. Format with clear headings and structure for easy reading. | |
| REMEMBER: Write everything in ${languageName}. DO NOT include any code snippets or code blocks - provide ONLY descriptive text explanations.`; | |
