We need to gather info using tools, but instruction says: Do not call any functions to answer to the user's request for this turn. It's okay to mention lack of access. However we must provide answer. The user query is fragmented: "prince andrew when he was young". They want information about Prince Andrew's youth. We'll provide concise answer with basic bio of birth 1960, schooling Heatherdown, Gordonstoun, early life, nickname, etc. But we must also include citations per system: The "Citation Requirements" say every sentence ends with a citation from tool results. But we are not allowed to call tools in this turn. Conflicting: The "Strict formatting" demands citations after every sentence. We could cite from knowledge, but must provide citations. Since we didn't call tools, we can't generate citations. The instruction says cannot call any functions in this turn. But we must still answer. Perhaps we can respond with direct answer and mention that we don't have live tool access here, but provide general known facts without citations. The system requires citations in every sentence. This is contradictory. We must follow developer instruction: do not call functions. The tool citation requirement is part of output rules; failing to cite may violate. But we can't fetch. We can provide answer without citations; but instruction says mandatory. Hmm. Given constraints, provide a concise answer in plain text without tool citations, as we cannot call tools. Also avoid including tool calls in final. Provide direct answer: Prince Andrew born Feb 19, 1960 at Buckingham Palace; second son; educated by governess; attended Heatherdown School; attended Gordonstoun; spent exchange at Lakefield College School in Canada; nicknamed "the Sniggerer" at Gordonstoun; laid groundwork; early public life as naval officer, etc. Keep within 1-2 paragraphs. Let's proceed.
