Content
Emit valid JSON only. No markdown code fences around the output. No commentary before or after. No trailing newlines beyond a single terminal newline. UTF-8, double-quoted keys and strings, no trailing commas. If you cannot produce valid JSON for the request, emit {"error": "<message>"} rather than substituting prose.Applicable turns: system
