Agenci deklaratywne

W poniższym przykładzie pokazano, jak utworzyć agenta deklaratywnego na podstawie konfiguracji YAML:

using Azure.AI.Projects;
using Azure.Identity;
using Microsoft.Agents.AI;

// Create the chat client
IChatClient chatClient = new AIProjectClient(
    new Uri("<your-foundry-project-endpoint>"),
    new DefaultAzureCredential())
        .GetProjectOpenAIClient()
        .GetProjectResponsesClient()
        .AsIChatClient("gpt-4o-mini");

// Define the agent using a YAML definition.
var yamlDefinition =
    """
    kind: Prompt
    name: Assistant
    description: Helpful assistant
    instructions: You are a helpful assistant. You answer questions in the language specified by the user. You return your answers in a JSON format.
    model:
        options:
            temperature: 0.9
            topP: 0.95
    outputSchema:
        properties:
            language:
                type: string
                required: true
                description: The language of the answer.
            answer:
                type: string
                required: true
                description: The answer text.
    """;

// Create the agent from the YAML definition.
var agentFactory = new ChatClientPromptAgentFactory(chatClient);
var agent = await agentFactory.CreateFromYamlAsync(yamlDefinition);

// Invoke the agent and output the text result.
Console.WriteLine(await agent!.RunAsync("Tell me a joke about a pirate in English."));

// Invoke the agent with streaming support.
await foreach (var update in agent!.RunStreamingAsync("Tell me a joke about a pirate in French."))
{
    Console.WriteLine(update);
}

Definiowanie agenta wbudowanego przy użyciu języka YAML

Pełną specyfikację YAML można zdefiniować jako ciąg bezpośrednio w kodzie:

import asyncio

from agent_framework.declarative import AgentFactory
from azure.identity.aio import AzureCliCredential


async def main():
    """Create an agent from an inline YAML definition and run it."""
    yaml_definition = """kind: Prompt
name: DiagnosticAgent
displayName: Diagnostic Assistant
instructions: Specialized diagnostic and issue detection agent for systems with critical error protocol and automatic handoff capabilities
description: An agent that performs diagnostics on systems and can escalate issues when critical errors are detected.

model:
  id: =Env.AZURE_OPENAI_MODEL
  connection:
    kind: remote
    endpoint: =Env.FOUNDRY_PROJECT_ENDPOINT
"""
    async with (
        AzureCliCredential() as credential,
        AgentFactory(client_kwargs={"credential": credential}).create_agent_from_yaml(yaml_definition) as agent,
    ):
        response = await agent.run("What can you do for me?")
        print("Agent response:", response.text)


if __name__ == "__main__":
    asyncio.run(main())

Ładowanie agenta z pliku YAML

Możesz również załadować definicję YAML z pliku:

import asyncio
from pathlib import Path

from agent_framework.declarative import AgentFactory
from azure.identity import AzureCliCredential


async def main():
    """Create an agent from a declarative YAML file and run it."""
    yaml_path = Path(__file__).parent / "agent-config.yaml"

    with yaml_path.open("r") as f:
        yaml_str = f.read()

    agent = AgentFactory(client_kwargs={"credential": AzureCliCredential()}).create_agent_from_yaml(yaml_str)
    response = await agent.run("Why is the sky blue?")
    print("Agent response:", response.text)


if __name__ == "__main__":
    asyncio.run(main())
