Structured Output (JSON/Schema)

Parse the following {{input_type}} and return a structured JSON response.

Input:
{{input_data}}

Output schema:
{
  "entities": [
    {
      "name": "string",
      "type": "{{entity_type}}",
      "attributes": { },
      "relationships": [{ "target": "string", "relation": "string" }],
      "confidence": "high | medium | low"
    }
  ],
  "summary": "string",
  "metadata": {
    "input_quality": "clean | noisy | ambiguous",
    "entities_found": "number",
    "processing_notes": "string"
  }
}

Rules:
- Return ONLY valid JSON, no markdown code fences, no explanation text
- If a field cannot be determined, use null (not empty string)
- Set confidence to "low" for any entity extracted from ambiguous context
- Deduplicate entities that appear multiple times with different names
