如何更好地与小龙虾(Openclaw)交流(二)–提示词工程的进阶技巧-结构化组件
角色定位
描述LLM应该扮演什么角色。例如,如果你想问一个关于天体物理学的问题,可以使用“你是一位天体物理学专家”。
指令
任务本身。指令应该尽可能具体,避免留下太大的解释空间。
上下文
描述问题或任务背景的附加信息。它回答了“为什么提出这个指令”这样的问题。
格式
LLM输出生成文本的格式。如果不指定格式,LLM会自行决定格式,这在自动化系统中会造成麻烦。
受众
生成文本的目标对象。这也描述了输出的水平。在教育目的下,使用ELI5(Explain like I’m 5,“向5岁的孩子解释”)通常很有帮助。
语气
LLM在生成文本中应该使用的语气。如果你要给老板写一封正式的邮件,你肯定不想使用非正式的语气。
数据
与任务本身相关的主要数据。
我们可以看一个典型示例,看看可以怎么用这些组件:
# 提示词的组件persona = "You are an expert in Large Language models. You excel at breaking down complex papers into digestible summaries.\n"instruction = "Summarize the key findings of the paper provided.\n"context = "Your summary should extract the most crucial points that can help researchers quickly understand the most vital information of the paper.\n"data_format = "Create a bullet-point summary that outlines the method. Follow this up with a concise paragraph that encapsulates the main results.\n"audience = "The summary is designed for busy researchers that quickly need to grasp the newest trends in Large Language Models.\n"tone = "The tone should be professional and clear.\n"text = "MY TEXT TO SUMMARIZE"data = f"Text to summarize: {text}"# 完整提示词(删除和添加片段以查看它对输出的影响)query = persona + instruction + context + data_format + audience + tone + data
增加这些组件后,变化不仅限于简单地添加或删除组件。正如我们之前在首因效应和近因效应中看到的那样,它们的顺序也会影响AI大模型输出的质量。换句话说,在为你的应用场景寻找最佳提示词时,实验是至关重要的。在提示工程中,我们本质上是在进行一个迭代的实验循环。
亲自动手试一试,在复杂提示词的基础上添加、删除部分组件,观察它对所生成输出的影响。你很快就会注意到哪些组件值得保留。你可以将自己的数据添加到data变量中,也可以添加各种组件,包括创意性组件,比如情感刺激(例如,“这对我的职业生涯非常重要”)等等。重要的,是通过组件这种方式,在我们的Prompt中,引入维度和结构化的概念,从而更好地与AI大模型进行交流。
像Openclaw、Hermes等这些Agent框架,其实背后实现,也是用这些丰富的组件来组织成Prompt输入给大模型,从而得到模型的时生成反馈,进而实现各种能力输出。下面,这是小龙虾(Openclaw)源码中,组织提示词时,进行主提示词组织的一部分代码(全部的提示词组织代码很长,有很多个部分)。我们不需要理解具体的代码逻辑,大家只用学习它用组件思想构建Prompt的思路就可以了(红色字符串都是构建Prompt的各个组件信息)。
