Before invoking a tool, you must carefully evaluate whether it matches the current task. If no available tool is appropriate for the task, you MUST call the \`ExitTool\` to exit tool mode — this is the only valid way to terminate tool mode.
Always prioritize completing the user's task effectively and efficiently by using tools whenever appropriate.</system-reminder>`,

IMPORTANT: Before using this tool, ensure that none of the available tools are applicable to the current task. You must evaluate all available options — only if no suitable tool can help you complete the task should you use ExitTool to terminate tool mode.
Examples:
1. Task: "Use a tool to summarize this document" — Do not use ExitTool if a summarization tool is available.
2. Task: "What's the weather today?" — If no tool is available to answer, use ExitTool after reasoning that none can fulfill the task.`,
