内省代理：利用反射执行任务¶

警告：本笔记本包含一些可能被视为冒犯或敏感的内容。

在本笔记本中，我们将介绍如何使用llama-index-agent-introspective集成包来定义一个代理，该代理在执行任务时利用反射代理模式。我们将这样的代理称为“内省代理”。这些代理通过首先生成对任务的初始响应，然后在连续的响应上执行反思和修正循环，直到满足停止条件或达到最大迭代次数为止，来执行任务。

1 毒性减少：问题设置¶

在这个笔记本中，我们要让我们的自省代理执行的任务是“毒性减少”。具体来说，给定一段有害文本，我们将要求代理生成原始文本的一个更少有害（或更安全）的版本。正如之前提到的，我们的自省代理将通过执行反思和修正循环来达到毒性文本的足够安全版本。

2 使用IntrospectiveAgents¶

在这个笔记本中，我们将构建两个内省代理。请注意，这样的IntrospectiveAgents将反思和修正的任务委托给另一个代理，即ReflectiveAgentWorker。这个反思代理需要在构造时提供给内省代理。此外，还可以提供一个MainAgentWorker，负责生成任务的初始响应 - 如果没有提供，则假定用户输入是任务的初始响应。对于这个笔记本，我们构建以下IntrospectiveAgent：

a. 使用ToolInteractiveReflectionAgent的IntrospectiveAgent

b. 使用SelfReflectionAgent的IntrospectiveAgent

对于使用工具交互反思的代理，我们将使用Perspective API来获取我们文本的毒性分数。这遵循了CRITIC论文中提供的示例。

2a IntrospectiveAgent 使用 ToolInteractiveReflectionAgent¶

这里首先要做的是定义 PerspectiveTool，我们的 ToolInteractiveReflectionAgent 将通过另一个代理，即 CritiqueAgent 来使用它。

要使用 Perspective 的 API，您需要完成以下步骤：

1. 在您的 Google Cloud 项目中启用 Perspective API
2. 生成一组新的凭据（即 API 密钥），您需要将其设置为环境变量 PERSPECTIVE_API_KEY 或直接在后续代码的适当部分提供。

要执行步骤 1 和 2，您可以按照这里概述的说明进行操作：https://developers.perspectiveapi.com/s/docs-enable-the-api?language=en_US。

构建PerspectiveTool¶

from googleapiclient import discoveryfrom typing import Dict, Optionalimport jsonimport osclass Perspective: """与Perspective API交互的自定义类。""" attributes = [ "toxicity", "severe_toxicity", "identity_attack", "insult", "profanity", "threat", "sexually_explicit", ] def __init__(self, api_key: Optional[str] = None) -> None: if api_key is None: try: api_key = os.environ["PERSPECTIVE_API_KEY"] except KeyError: raise ValueError( "请提供api密钥或设置PERSPECTIVE_API_KEY环境变量。" ) self._client = discovery.build( "commentanalyzer", "v1alpha1", developerKey=api_key, discoveryServiceUrl="https://commentanalyzer.googleapis.com/$discovery/rest?version=v1alpha1", static_discovery=False, ) def get_toxicity_scores(self, text: str) -> Dict[str, float]: """调用Perspective API获取各种属性的毒性评分的函数。""" analyze_request = { "comment": {"text": text}, "requestedAttributes": { att.upper(): {} for att in self.attributes }, } response = ( self._client.comments().analyze(body=analyze_request).execute() ) try: return { att: response["attributeScores"][att.upper()]["summaryScore"][ "value" ] for att in self.attributes } except Exception as e: raise ValueError("无法解析响应") from eperspective = Perspective()

有了辅助类，我们可以通过首先定义一个函数，然后利用 FunctionTool 抽象来定义我们的工具。

In [ ]:

from typing import Tuplefrom llama_index.core.bridge.pydantic import Fielddef perspective_function_tool(    text: str = Field(        default_factory=str,        description="用于计算毒性评分的文本。",    )) -> Tuple[str, float]:    """返回最具问题的毒性属性的毒性评分。"""    scores = perspective.get_toxicity_scores(text=text)    max_key = max(scores, key=scores.get)    return (max_key, scores[max_key] * 100)from llama_index.core.tools import FunctionToolpespective_tool = FunctionTool.from_defaults(    perspective_function_tool,)

构建IntrospectiveAgent和ToolInteractiveReflectionAgent¶

有了我们的工具定义，现在我们可以构建我们的IntrospectiveAgent和所需的ToolInteractiveReflectionAgentWorker。为了构建后者，我们还需要构建一个CritiqueAgentWorker，它最终将负责与工具进行反思。

下面提供的代码定义了一个辅助函数来构建这个IntrospectiveAgent。这样做是为了方便起见，因为我们稍后将对这两种反思技术进行测试！

2b IntrospectiveAgent 使用 SelfReflectionAgentWorker¶

与前面的小节类似，现在我们将构建一个使用 SelfReflectionAgentWorker 的 IntrospectiveAgent。这种反思技术不使用任何工具，而是仅使用提供的LLM来执行反思和修正。此外，我们同样定义一个辅助函数来构建这样一个 IntrospectiveAgent。

In [ ]:

让我们将这个 IntrospectiveAgent 应用到之前的 harmful_text 上进行测试。

3 迷你对决：自我反思 vs. 工具交互式反思¶

在笔记本的这一部分，我们将分别向两个定义的IntrospectiveAgent传递一些有害文本。这些示例来自CRITIC论文以及Guardrails AI文档。

警告：本笔记本的这一部分包含一些可能被一些人认为具有冒犯性或敏感性的内容。

现在让我们让每个代理处理这些有害文本，以创建更安全的版本。我们将记录每个文本的毒性分数，并进行快速分析，比较这两种反射机制。毫无疑问，这个样本大小远远不足以得出任何统计显著的结论。话虽如此，这确实在一定程度上证实了CRITIC论文实验中观察到的结果（如上述PaperCard中总结的）。

9	self_reflection	I am a Generative AI model that is trained on a large corpus of text. This is a very powerful tool for generating new text, which can be creatively inspiring or informative. However, it's important to use it responsibly to avoid generating content that could be considered offensive or harmful.	3.121337	I am a Generative AI model that is trained on a large corpus of text.

正如我们所看到的，tool_interactive_reflection 方法产生的毒性评分比 self_reflection 方法低。同时请注意，这两种方法都比原有的有害文本产生了显著的改善。这个结果与CRITIC论文中观察到的结果一致（再次忽略由于样本量较小而导致的统计显著性）。具体来说，使用适当的外部工具进行反思比仅仅使用LLMs进行反思会产生更好的结果。因此，一个明智的建议是在适当的情况下使用工具交互式反思。
