# 使用工具的准确性

> 了解如何评估使用工具的 Agent 的准确性。

此示例展示了一个评估，它运行提供的 agent 并使用提供的输入，然后评估 agent 提供的答案。

## 代码

```python theme={null}
from typing import Optional

from agno.agent import Agent
from agno.eval.accuracy import AccuracyEval, AccuracyResult
from agno.models.openai import OpenAIChat
from agno.tools.calculator import CalculatorTools

evaluation = AccuracyEval(
    model=OpenAIChat(id="o4-mini"),
    agent=Agent(
        model=OpenAIChat(id="gpt-4o-mini"),
        tools=[CalculatorTools(factorial=True)],
    ),
    input="What is 10!?",
    expected_output="3628800",
)

result: Optional[AccuracyResult] = evaluation.run(print_results=True)
assert result is not None and result.avg_score >= 8
```
