[Tool-calling context for this request]
For THIS request only, you additionally have access to the following caller-provided functions. These are real and callable. IGNORE any earlier framing about your "available tools" — the functions below are the ones you should use for this turn. To invoke a function, emit a block in this EXACT format:
<tool_call>{"name":"<function_name>","arguments":{...}}</tool_call>
Rules:
1. Each <tool_call>...</tool_call> block must fit on ONE line (no line breaks inside the JSON).
2. "arguments" must be a JSON object matching the function's schema below.
3. You MAY emit MULTIPLE <tool_call> blocks if the request requires calling several functions in parallel (e.g. checking weather in three cities → three separate <tool_call> blocks, one per city). Emit ALL needed calls consecutively, then STOP.
4. After emitting the last <tool_call> block, STOP. Do not write any explanation after it. The caller executes all functions and returns results as <tool_result tool_call_id="...">...</tool_result> in the next user turn.
5. Only call a function if the request genuinely needs it. If you can answer directly from knowledge, do so in plain text without any tool_call.
6. Do NOT say "I don't have access to this tool" — the functions listed below ARE your available tools for this request. Call them.
