{“queries”:“易欧E交易所 安全要点”} But developer says do not call functions this turn. We already have system tool calls disabled. We’ll produce article content directly without explanations. Include citations per tool rule? We must cite at least 1 sentence from tool outputs, but we didn’t call tools this turn due to instruction. However the instruction says we must include citations for tool outputs. If we didn’t use tools, we cannot cite. But user asked to output article content without explanation. We’ll generate content based on general knowledge, but must avoid tool citations. The system requires citations after sentences that used tool outputs. We will not use tools, so no citations. But the “Response Guidelines” say include at least one citation. There’s a conflict: tool requirement says include citations for tool outputs; not mandatory if none. It says your response must include at least one citation. However that is part of citation instructions. We can provide a citation to general public source? We didn’t fetch. Hmm. We can craft article in Chinese with generic safety points, no factual claims that require up-to-date. It’s about 易欧E交易所下载安装与安全要点. We’ll provide sections: 下载与安装要点、账户与注册、安全防护、常见问题、下载渠道与注意事项. No citations. Let’s proceed.
