人类代理

Microsoft Agent 框架支持创建使用 Anthropic 的 Claude 模型的代理。

入门

将所需的 NuGet 包添加到项目。

dotnet add package Microsoft.Agents.AI.Anthropic --prerelease

如果使用 Azure Foundry,请添加:

dotnet add package Anthropic.Foundry --prerelease
dotnet add package Azure.Identity

配置

环境变量

为人类身份验证设置所需的环境变量:

# Required for Anthropic API access
$env:ANTHROPIC_API_KEY="your-anthropic-api-key"
$env:ANTHROPIC_DEPLOYMENT_NAME="claude-haiku-4-5"  # or your preferred model

可以从 人类控制台获取 API 密钥。

对于包含 API 密钥的 Azure Foundry

$env:ANTHROPIC_RESOURCE="your-foundry-resource-name"  # Subdomain before .services.ai.azure.com
$env:ANTHROPIC_API_KEY="your-anthropic-api-key"
$env:ANTHROPIC_DEPLOYMENT_NAME="claude-haiku-4-5"

对于使用 Azure CLI 的 Azure Foundry

$env:ANTHROPIC_RESOURCE="your-foundry-resource-name"  # Subdomain before .services.ai.azure.com
$env:ANTHROPIC_DEPLOYMENT_NAME="claude-haiku-4-5"

注释

将 Azure Foundry 与 Azure CLI 配合使用时,请确保已登录 az login 并有权访问 Azure Foundry 资源。 有关详细信息,请参阅 Azure CLI 文档

创建人类代理

基本代理创建(人类公共 API)

使用公共 API 创建人类代理的最简单方法:

var apiKey = Environment.GetEnvironmentVariable("ANTHROPIC_API_KEY");
var deploymentName = Environment.GetEnvironmentVariable("ANTHROPIC_DEPLOYMENT_NAME") ?? "claude-haiku-4-5";

AnthropicClient client = new() { APIKey = apiKey };

AIAgent agent = client.AsAIAgent(
    model: deploymentName,
    name: "HelpfulAssistant",
    instructions: "You are a helpful assistant.");

// Invoke the agent and output the text result.
Console.WriteLine(await agent.RunAsync("Hello, how can you help me?"));

在 Azure Foundry 上使用 Anthropic 和 API 密钥

在 Azure Foundry 上设置人类学后,可以将它与 API 密钥身份验证一起使用:

var resource = Environment.GetEnvironmentVariable("ANTHROPIC_RESOURCE");
var apiKey = Environment.GetEnvironmentVariable("ANTHROPIC_API_KEY");
var deploymentName = Environment.GetEnvironmentVariable("ANTHROPIC_DEPLOYMENT_NAME") ?? "claude-haiku-4-5";

AnthropicClient client = new AnthropicFoundryClient(
    new AnthropicFoundryApiKeyCredentials(apiKey, resource));

AIAgent agent = client.AsAIAgent(
    model: deploymentName,
    name: "FoundryAgent",
    instructions: "You are a helpful assistant using Anthropic on Azure Foundry.");

Console.WriteLine(await agent.RunAsync("How do I use Anthropic on Foundry?"));

在 Azure Foundry 上使用 Anthropic 以及 Azure 凭据(Azure CLI 凭据示例)

在优先使用 Azure 凭据的环境中:

var resource = Environment.GetEnvironmentVariable("ANTHROPIC_RESOURCE");
var deploymentName = Environment.GetEnvironmentVariable("ANTHROPIC_DEPLOYMENT_NAME") ?? "claude-haiku-4-5";

AnthropicClient client = new AnthropicFoundryClient(
    new AnthropicAzureTokenCredential(new DefaultAzureCredential(), resource));

AIAgent agent = client.AsAIAgent(
    model: deploymentName,
    name: "FoundryAgent",
    instructions: "You are a helpful assistant using Anthropic on Azure Foundry.");

Console.WriteLine(await agent.RunAsync("How do I use Anthropic on Foundry?"));

/// <summary>
/// Provides methods for invoking the Azure hosted Anthropic models using <see cref="TokenCredential"/> types.
/// </summary>
public sealed class AnthropicAzureTokenCredential(TokenCredential tokenCredential, string resourceName) : IAnthropicFoundryCredentials
{
    /// <inheritdoc/>
    public string ResourceName { get; } = resourceName;

    /// <inheritdoc/>
    public void Apply(HttpRequestMessage requestMessage)
    {
        requestMessage.Headers.Authorization = new AuthenticationHeaderValue(
                scheme: "bearer",
                parameter: tokenCredential.GetToken(new TokenRequestContext(scopes: ["https://ai.azure.com/.default"]), CancellationToken.None)
                    .Token);
    }
}

警告

DefaultAzureCredential 对于开发来说很方便,但在生产中需要仔细考虑。 在生产环境中,请考虑使用特定凭据(例如), ManagedIdentityCredential以避免延迟问题、意外凭据探测以及回退机制的潜在安全风险。

小窍门

有关完整的可运行示例,请参阅 .NET 示例

使用代理

代理是标准 AIAgent 代理,支持所有标准代理操作。

有关如何运行和与代理交互的详细信息,请参阅 代理入门教程

先决条件

安装 Microsoft Agent Framework Anthropic 包。

pip install agent-framework-anthropic --pre

配置

环境变量

为人类身份验证设置所需的环境变量:

# Required for Anthropic API access
ANTHROPIC_API_KEY="your-anthropic-api-key"
ANTHROPIC_CHAT_MODEL_ID="claude-sonnet-4-5-20250929"  # or your preferred model

或者,可以在项目根目录中使用 .env 文件:

ANTHROPIC_API_KEY=your-anthropic-api-key
ANTHROPIC_CHAT_MODEL_ID=claude-sonnet-4-5-20250929

可以从 人类控制台获取 API 密钥。

入门

从代理框架导入所需的类:

import asyncio
from agent_framework.anthropic import AnthropicClient

创建人类代理

基本代理创建

创建人类代理的最简单方法:

async def basic_example():
    # Create an agent using Anthropic
    agent = AnthropicClient().as_agent(
        name="HelpfulAssistant",
        instructions="You are a helpful assistant.",
    )

    result = await agent.run("Hello, how can you help me?")
    print(result.text)

使用显式配置

可以提供显式配置,而不是依赖于环境变量:

async def explicit_config_example():
    agent = AnthropicClient(
        model_id="claude-sonnet-4-5-20250929",
        api_key="your-api-key-here",
    ).as_agent(
        name="HelpfulAssistant",
        instructions="You are a helpful assistant.",
    )

    result = await agent.run("What can you do?")
    print(result.text)

在 Foundry 上使用人类学

在 Foundry 上设置人类学后,请确保设置了以下环境变量:

ANTHROPIC_FOUNDRY_API_KEY="your-foundry-api-key"
ANTHROPIC_FOUNDRY_RESOURCE="your-foundry-resource-name"

然后创建代理,如下所示:

from agent_framework.anthropic import AnthropicClient
from anthropic import AsyncAnthropicFoundry

async def foundry_example():
    agent = AnthropicClient(
        anthropic_client=AsyncAnthropicFoundry()
    ).as_agent(
        name="FoundryAgent",
        instructions="You are a helpful assistant using Anthropic on Foundry.",
    )

    result = await agent.run("How do I use Anthropic on Foundry?")
    print(result.text)

注意:需要安装 anthropic>=0.74.0

代理功能

函数工具

为代理配备自定义功能:

from typing import Annotated

def get_weather(
    location: Annotated[str, "The location to get the weather for."],
) -> str:
    """Get the weather for a given location."""
    conditions = ["sunny", "cloudy", "rainy", "stormy"]
    return f"The weather in {location} is {conditions[randint(0, 3)]} with a high of {randint(10, 30)}°C."

async def tools_example():
    agent = AnthropicClient().as_agent(
        name="WeatherAgent",
        instructions="You are a helpful weather assistant.",
        tools=get_weather,  # Add tools to the agent
    )

    result = await agent.run("What's the weather like in Seattle?")
    print(result.text)

流式处理响应

对即时生成的响应进行获取,以提升用户体验。

async def streaming_example():
    agent = AnthropicClient().as_agent(
        name="WeatherAgent",
        instructions="You are a helpful weather agent.",
        tools=get_weather,
    )

    query = "What's the weather like in Portland and in Paris?"
    print(f"User: {query}")
    print("Agent: ", end="", flush=True)
    async for chunk in agent.run(query, stream=True):
        if chunk.text:
            print(chunk.text, end="", flush=True)
    print()

托管工具

人类代理支持托管的工具,例如 Web 搜索、MCP(模型上下文协议)和代码执行:

from agent_framework.anthropic import AnthropicClient

async def hosted_tools_example():
    client = AnthropicClient()
    agent = client.as_agent(
        name="DocsAgent",
        instructions="You are a helpful agent for both Microsoft docs questions and general questions.",
        tools=[
            client.get_mcp_tool(
                name="Microsoft Learn MCP",
                url="https://learn.microsoft.com/api/mcp",
            ),
            client.get_web_search_tool(),
        ],
        max_tokens=20000,
    )

    result = await agent.run("Can you compare Python decorators with C# attributes?")
    print(result.text)

扩展思维(推理)

Anthropic通过thinking功能支持扩展思维能力,使模型能够展示其推理过程。

from agent_framework import TextReasoningContent, UsageContent
from agent_framework.anthropic import AnthropicClient

async def thinking_example():
    client = AnthropicClient()
    agent = client.as_agent(
        name="DocsAgent",
        instructions="You are a helpful agent.",
        tools=[client.get_web_search_tool()],
        default_options={
            "max_tokens": 20000,
            "thinking": {"type": "enabled", "budget_tokens": 10000}
        },
    )

    query = "Can you compare Python decorators with C# attributes?"
    print(f"User: {query}")
    print("Agent: ", end="", flush=True)

    async for chunk in agent.run(query, stream=True):
        for content in chunk.contents:
            if isinstance(content, TextReasoningContent):
                # Display thinking in a different color
                print(f"\033[32m{content.text}\033[0m", end="", flush=True)
            if isinstance(content, UsageContent):
                print(f"\n\033[34m[Usage: {content.details}]\033[0m\n", end="", flush=True)
        if chunk.text:
            print(chunk.text, end="", flush=True)
    print()

人类技能

Anthropic 提供了可扩展代理功能的托管技能,例如创建 PowerPoint 演示文稿。 技能需要代码解释器工具才能正常工作:

from agent_framework import HostedFileContent
from agent_framework.anthropic import AnthropicClient

async def skills_example():
    # Create client with skills beta flag
    client = AnthropicClient(additional_beta_flags=["skills-2025-10-02"])

    # Create an agent with the pptx skill enabled
    # Skills require the Code Interpreter tool
    agent = client.as_agent(
        name="PresentationAgent",
        instructions="You are a helpful agent for creating PowerPoint presentations.",
        tools=client.get_code_interpreter_tool(),
        default_options={
            "max_tokens": 20000,
            "thinking": {"type": "enabled", "budget_tokens": 10000},
            "container": {
                "skills": [{"type": "anthropic", "skill_id": "pptx", "version": "latest"}]
            },
        },
    )

    query = "Create a presentation about renewable energy with 5 slides"
    print(f"User: {query}")
    print("Agent: ", end="", flush=True)

    files: list[HostedFileContent] = []
    async for chunk in agent.run(query, stream=True):
        for content in chunk.contents:
            match content.type:
                case "text":
                    print(content.text, end="", flush=True)
                case "text_reasoning":
                    print(f"\033[32m{content.text}\033[0m", end="", flush=True)
                case "hosted_file":
                    # Catch generated files
                    files.append(content)

    print("\n")

    # Download generated files
    if files:
        print("Generated files:")
        for idx, file in enumerate(files):
            file_content = await client.anthropic_client.beta.files.download(
                file_id=file.file_id,
                betas=["files-api-2025-04-14"]
            )
            filename = f"presentation-{idx}.pptx"
            with open(filename, "wb") as f:
                await file_content.write_to_file(f.name)
            print(f"File {idx}: {filename} saved to disk.")
