// The toolNames slice should contain the actual tool names available in the

return `TOOL CALL FORMAT — FOLLOW EXACTLY:
When calling tools, emit ONLY raw XML. No text before, no text after, no markdown fences.
<tool_calls>
<tool_call>
<tool_name>TOOL_NAME_HERE</tool_name>
<parameters>{"key":"value"}</parameters>
</tool_call>
</tool_calls>
RULES:
1) Output ONLY the XML above when calling tools. Do NOT mix tool XML with regular text.
2) <parameters> MUST contain a strict JSON object. All JSON keys and strings use double quotes.
3) Multiple tools → multiple <tool_call> blocks inside ONE <tool_calls> root.
4) Do NOT wrap the XML in markdown code fences (no triple backticks).
5) After receiving a tool result, use it directly. Only call another tool if the result is insufficient.
6) If you want to say something AND call a tool, output text first, then the XML block on its own.
❌ WRONG — Do NOT do these:
Wrong 1 — mixed text and XML:
I'll read the file for you. <tool_calls><tool_call>...
Wrong 2 — describing tool calls in text:
[调用 Bash] {"command": "ls"}
Wrong 3 — missing <tool_calls> wrapper:
<tool_call><tool_name>` + ex1 + `</tool_name><parameters>{}</parameters></tool_call>
✅ CORRECT EXAMPLES:
Example A — Single tool:
<tool_calls>
<tool_call>
<tool_name>` + ex1 + `</tool_name>
<parameters>{"path":"src/main.go"}</parameters>
</tool_call>
</tool_calls>
Example B — Two tools in parallel:
<tool_calls>
<tool_call>
<tool_name>` + ex1 + `</tool_name>
<parameters>{"path":"config.json"}</parameters>
</tool_call>
<tool_call>
<tool_name>` + ex2 + `</tool_name>
<parameters>{"path":"output.txt","content":"Hello world"}</parameters>
</tool_call>
</tool_calls>
Example C — Tool with complex nested JSON parameters:
<tool_calls>
<tool_call>
<tool_name>` + ex3 + `</tool_name>
<parameters>{"question":"Which approach do you prefer?","follow_up":[{"text":"Option A"},{"text":"Option B"}]}</parameters>
</tool_call>
</tool_calls>
Remember: Output ONLY the <tool_calls>...</tool_calls> XML block when calling tools.`
