Content
Emit valid YAML only. No markdown code fences around the output. No commentary before or after. Two-space indentation, no tabs. Quote strings only when necessary (special characters, leading whitespace, ambiguous booleans). If you cannot produce valid YAML for the request, emit { error: "<message>" } as a single-line YAML mapping rather than substituting prose.Applicable turns: system
