We will gather information using tools, but the developer instruction says you cannot call any functions to answer to the user's request for this turn. So in this turn, we should not call tools. But system requires at least one tool call before answering? The "Stop Conditions" say must call at least one tool before answering. However developer instruction overrides? It says you cannot call any functions to answer to the user's request for this turn. So we should refrain from tool calls and provide answer based on knowledge. The user asked proverb "proverbio quando il saggio indica la luna" Likely request for explanation of proverb in Italian: When the wise points to the moon, the fool watches the finger. Provide meaning and usage. Include translation markup per system reminder: wrap foreign language text in [text](javascript:void(0)). Since user's content is Italian; maybe provide explanation and how to use. Also maintain citation requirements? That requires tool citations in final answer, but since we won't use tools, we can't cite. The instruction says must include citations for each sentence, but tool results provide citations. If we can't call tools, we should still answer but no citations? The strict formatting demands citations in every sentence. This is conflicting. The higher-priority system says citations mandatory. But we can't fetch. We can respond with direct answer and maybe none citations? It says must end with citations. Hmm. We can proceed with explanation in Italian, include the proverb, its meaning, origins: Chinese origin, criticizes missing the point, focusing on the messenger. Provide examples and usage. Use [translate:] markup for any foreign language text. The proverb is already Italian translation; we can present the original Chinese? The proverb in Chinese: 老子? Actually proverb is "指月" in Chinese: "指月" or "指月不是". Common version: "指月看手指" Not sure. We'll include translation: "Quando il saggio indica la luna, lo stolto guarda il dito." in [...](javascript:void(0))? The rule says wrap any foreign language text. The Italian sentence is Italian; not necessary. The original proverb Chinese would be foreign. We can include as [當賢者指月，愚者觀指](javascript:void(0)) maybe. But accuracy? Could say Chinese origin proverb: "当圣者指月，愚者看指" Not confident. Maybe avoid providing exact Chinese characters, to avoid errors. Use a safe approach: Provide meaning and usage without embedding foreign text. But instruction says wrap any foreign language text in [text](javascript:void(0)). If we don't include any foreign language text, it's fine. Let's answer concisely with sections: Significato, Origine e uso, Esempi. Include a few bullet points. End with direct answer. Also since no tool usage, we must not violate. Let's proceed.
