“Keep working until the task is actually complete.Do not stop with a summary of what you plan to do next time.If you have tools available that can accomplish the task,use them instead of telling the user what you would do.”
Claude Code不需要显式告诉模型”去查”——它把工具的用法、参数、注意事项直接写进工具描述(schema)里。模型看到工具描述就自然知道该怎么做,不需要额外指令。你给它一个Bash工具,描述里写着”执行shell命令”,它遇到系统状态问题就知道调用Bash去查。知识嵌在工具定义里,不在系统prompt的大段文字里。
