The user wants me to rewrite a horse-racing news item as an original editorial article. However, the source content is empty - there's no actual content provided in the "Source" fi

Since there's no source content to rewrite, I cannot create an original article based on non-existent information. I need to inform the user that the source content is missing.

Wait, let me re-read the instructions. The user says "Rewrite the following horse-racing news item" but provides no actual news item content. The source summary is empty and the source URL is empty.

I should respond that I cannot complete this task because no source content was provided. I need to return JSON as specified in the instructions.

Let me construct an appropriate response:

{
"error": "No source content provided",
"message": "The source article content is empty. Please provide the article text you would like me to rewrite as an original editorial article."
}

Actually, looking at the instructions again, the user wants me to return JSON with specific keys. Since I cannot create the article without source content, I should return an error response in JSON format as requested.

Let me provide a clear error message in JSON format.

{"error": "Source content missing", "message": "No source article content was provided. The source summary and URL fields are empty, making it impossible to rewrite the article. Please provide the original article text you would like me to transform into an original editorial piece."}
