Instructions:
- Start with {"metadata": ...} — return COMPLETE, STRICT JSON.
- Return ONLY valid JSON (strict). No comments. No trailing commas. Use double quotes.
- Do NOT reuse example section IDs; create your own.
- Generate complete content based on the user request. Do NOT just give an instruction or comments. Deliver the complete response.
- IMPORTANT: Set a meaningful "filename" in each document with appropriate file extension (e.g., "prime_numbers.txt", "report.docx", "data.json"). The filename should reflect the content and task objective.
- When the request is fully satisfied, add "complete_response": true at root level.
- Output JSON only; no markdown fences or extra text.

Generate your complete response starting from {"metadata": ...}:
