Evaluation

.NET에서 평가 프레임워크는 Microsoft.Extensions.AI.Evaluation을 기반으로 구축됩니다. 평가자는 IAgentEvaluator 인터페이스를 구현하고, 오케스트레이션은 AIAgent 및 Run의 확장 메서드를 통해 제공됩니다.

핵심 형식은 Microsoft.Agents.AI 네임스페이스에 있습니다.

using Microsoft.Agents.AI;

Python 평가 프레임워크는 핵심 agent_framework 패키지의 일부입니다. 평가자는 Evaluator 프로토콜을 구현하며, 오케스트레이션은 evaluate_agent() 및 evaluate_workflow() 함수를 통해 제공됩니다.

from agent_framework import (
    evaluate_agent,
    evaluate_workflow,
    EvalItem,
    EvalResults,
    LocalEvaluator,
)

기본 제공 검사

에이전트 프레임워크는 일반적인 시나리오에 대한 기본 제공 검사와 함께 제공됩니다.

using Microsoft.Agents.AI;

var local = new LocalEvaluator(
    EvalChecks.KeywordCheck("weather", "temperature"),  // Response must contain these keywords
    EvalChecks.ToolCalledCheck("get_weather")            // Agent must have called this tool
);

사용자 지정 함수 계산기

모든 함수를 평가기 검사를 위한 래핑 도구로 FunctionEvaluator.Create()를 사용합니다. 필요한 데이터에 따라 여러 오버로드를 사용할 수 있습니다.

using Microsoft.Agents.AI;

var local = new LocalEvaluator(
    // Simple: check only the response text
    FunctionEvaluator.Create("is_concise",
        (string response) => response.Split(' ').Length < 500),

    // With expected output: compare against ground truth
    FunctionEvaluator.Create("mentions_city",
        (string response, string? expectedOutput) =>
            expectedOutput != null && response.Contains(expectedOutput, StringComparison.OrdinalIgnoreCase)),

    // Full context: access the complete EvalItem
    FunctionEvaluator.Create("used_search",
        (EvalItem item) => item.Conversation.Any(m =>
            m.Text?.Contains("search", StringComparison.OrdinalIgnoreCase) == true))
);

기본 제공 검사

에이전트 프레임워크는 일반적인 시나리오에 대한 기본 제공 검사와 함께 제공됩니다.

from agent_framework import (
    LocalEvaluator,
    keyword_check,
    tool_called_check,
    tool_calls_present,
    tool_call_args_match,
)

local = LocalEvaluator(
    keyword_check("weather", "temperature"),  # Response must contain these keywords
    tool_called_check("get_weather"),          # Agent must have called this tool
    tool_calls_present,                        # All expected tool call names were made
    tool_call_args_match,                      # Expected tool calls match on name + args
)

사용자 지정 함수 계산기

@evaluator 데코레이터를 사용하여 모든 함수를 평가자 검사로 래핑합니다. 함수의 매개 변수 이름은 EvalItem로부터 데이터를 수신할 때 그것을 결정합니다.

from agent_framework import evaluator, LocalEvaluator

@evaluator
def is_concise(response: str) -> bool:
    """Check response is under 500 words."""
    return len(response.split()) < 500

@evaluator
def mentions_city(response: str, expected_output: str) -> bool:
    """Check response contains the expected city name."""
    return expected_output.lower() in response.lower()

@evaluator
def used_tools(conversation: list, tools: list) -> float:
    """Score based on tool usage. Returns 0.0–1.0 (>= 0.5 passes)."""
    tool_calls = [c for m in conversation for c in (m.contents or []) if c.type == "function_call"]
    return min(len(tool_calls) / max(len(tools), 1), 1.0)

local = LocalEvaluator(is_concise, mentions_city, used_tools)

지원되는 매개 변수 이름: query,response, expected_output, expected_tool_callsconversation, toolscontext.

반환 형식: bool, float (≥ 0.5 = pass), dict 및 score 키 또는 passed 또는 CheckResult. 비동기 함수는 자동으로 처리됩니다.

using Microsoft.Agents.AI.AzureAI;

var foundry = new FoundryEvals(chatConfiguration, FoundryEvals.Relevance, FoundryEvals.Coherence);

from agent_framework.foundry import FoundryEvals

evals = FoundryEvals(
    project_client=project_client,
    model="gpt-4o",
    evaluators=[FoundryEvals.RELEVANCE, FoundryEvals.COHERENCE],
)

using Microsoft.Agents.AI;
using Microsoft.Agents.AI.Foundry;

var foundry = new FoundryEvals(chatConfiguration, FoundryEvals.Relevance, FoundryEvals.Coherence);

AgentEvaluationResults results = await agent.EvaluateAsync(
    new[]
    {
        "What's the weather in Seattle?",
        "Plan a weekend trip to Portland",
        "What restaurants are near Pike Place?",
    },
    foundry);

results.AssertAllPassed();  // Throws if any item failed

EvaluateAsync는 AIAgent에 대한 확장 메서드입니다. 쿼리당 한 번씩 에이전트를 실행하고, 각 상호작용을 EvalItem로 변환하고, 일괄 처리로 평가자에게 전달합니다.

from agent_framework import evaluate_agent
from agent_framework.foundry import FoundryEvals

evals = FoundryEvals(
    project_client=project_client,
    model="gpt-4o",
    evaluators=[FoundryEvals.RELEVANCE, FoundryEvals.COHERENCE],
)

results = await evaluate_agent(
    agent=my_agent,
    queries=[
        "What's the weather in Seattle?",
        "Plan a weekend trip to Portland",
        "What restaurants are near Pike Place?",
    ],
    evaluators=evals,
)

for r in results:
    print(f"{r.provider}: {r.passed}/{r.total}")
    r.raise_for_status()  # Raises EvalNotPassedError if any item failed

evaluate_agent 는 쿼리당 한 번씩 에이전트를 실행하고, 각 상호 작용을 변환 EvalItem하고, 일괄 처리를 계산기로 전달합니다. 평가자 공급자당 하나씩 EvalResults를 반환합니다.

AgentEvaluationResults results = await agent.EvaluateAsync(
    new[] { "What's the weather in Seattle?" },
    foundry,
    numRepetitions: 3);  // Each query runs 3 times independently
// Results contain 3 items (1 query × 3 repetitions)

results = await evaluate_agent(
    agent=my_agent,
    queries=["What's the weather in Seattle?"],
    evaluators=evals,
    num_repetitions=3,  # Each query runs 3 times independently
)
# Results contain 3 items (1 query × 3 repetitions)

AgentEvaluationResults results = await agent.EvaluateAsync(
    new[] { "What's 2+2?", "Capital of France?" },
    foundry,
    expectedOutput: new[] { "4", "Paris" });

필요한 도구 호출을 지정할 수도 있습니다.

AgentEvaluationResults results = await agent.EvaluateAsync(
    new[] { "What's the weather in NYC?" },
    new LocalEvaluator(EvalChecks.ToolCalledCheck("get_weather")),
    expectedToolCalls: new[]
    {
        new[] { new ExpectedToolCall("get_weather") },
    });

from agent_framework import evaluate_agent, ExpectedToolCall

results = await evaluate_agent(
    agent=my_agent,
    queries=["What's 2+2?", "Capital of France?"],

    evaluators=evals,
)

필요한 도구 호출을 지정할 수도 있습니다.

    agent=my_agent,
    queries=["What's the weather in NYC?"],
    expected_tool_calls=[ExpectedToolCall("get_weather", {"location": "NYC"})],
    evaluators=local,
)

var response = await agent.RunAsync(new[] { new ChatMessage(ChatRole.User, "What's the weather?") });

AgentEvaluationResults results = await agent.EvaluateAsync(
    new[] { response },
    new[] { "What's the weather?" },
    foundry);

from agent_framework import Message, evaluate_agent

response = await agent.run([Message("user", ["What's the weather?"])])

results = await evaluate_agent(
    agent=agent,

// Full conversation as context
AgentEvaluationResults results = await agent.EvaluateAsync(
    new[] { "Plan a 3-day trip to Paris" },
    foundry,
    splitter: ConversationSplitters.Full);

// Per-turn: each exchange scored independently
var items = EvalItem.PerTurnItems(conversation);
var perTurnResults = await evaluator.EvaluateAsync(items);

다음을 구현하여 사용자 지정 분할자를 구현할 수도 있습니다.IConversationSplitter

public class SplitBeforeToolCall : IConversationSplitter
{
    public (IReadOnlyList<ChatMessage> QueryMessages, IReadOnlyList<ChatMessage> ResponseMessages) Split(
        IReadOnlyList<ChatMessage> conversation)
    {
        // Custom split logic
        for (int i = 0; i < conversation.Count; i++)
        {
            if (conversation[i].Text?.Contains("tool_call") == true)
                return (conversation.Take(i).ToList(), conversation.Skip(i).ToList());
        }
        return ConversationSplitters.LastTurn.Split(conversation);
    }
}

# Full conversation as context
results = await evaluate_agent(

)

# Per-turn: each exchange scored independently
from agent_framework import EvalItem

items = EvalItem.per_turn_items(conversation)
# Pass items directly to an evaluator
per_turn_results = await evaluator.evaluate(items)

대화를 인자로 받아서 (query_messages, response_messages)을 반환하는 호출 가능한 사용자 지정 분할자를 제공할 수도 있습니다.
