# Tool Usage Efficiency

Check how efficiently the tools are used in your agent pipeline

### Tool Usage Efficiency

#### Objective

This metric evaluates the effectiveness and efficiency with which an AI system utilizes the tools at its disposal to accomplish tasks. It measures how well the AI optimizes tool usage to achieve the desired outcomes with minimal redundancy and resource expenditure.

#### Interpretation

A score closer to 1.0 indicates that the AI consistently uses tools in a highly efficient and effective manner, maximizing outcomes while minimizing unnecessary actions. A score closer to 0.0 suggests that the AI's tool usage is inefficient, involving redundant or poorly executed tool calls that may hinder task completion.

#### Syntax

```python
# Tool Usage Efficiency
response = experiment_manager.execute(
    metrics=[
        {"name": "tool_usage_efficiency", "config": {"model": "gpt-4o-mini"}}
    ]
)
```
