Tool Efficiency Scorer
Software componentObservability & EvaluationObservability & Evaluationarc:ToolEfficiencyScorer
A response scorer that analyses an agent's tool-call sequence for a task and penalizes redundant or suboptimal invocations.
Responsibility. Scores how efficiently an agent used tools to complete a task.
Also known as: Tool utilization effectiveness
Variant of Response Scorer abstract
When to choose. Choose when the agent exposes a tool-call log and operational efficiency matters.
Relationships
is invoked by dependency
reads dependency
Design guidance
- SHOULD penalize redundant calls while recognizing that complex tasks legitimately require multiple invocations.
Classification
- Risks mitigated
- Unnecessary API cost from redundant tool calls
