# Metrics

Agentic Testing in **RagaAI Catalyst** is built for evaluating advanced, autonomous AI systems. Agentic applications are capable of planning, reasoning, and executing multi-step tasks that require specialized metrics that can handle dynamic behavior, trace-level evaluation, and safety validation.

### Why These Metrics Matter

* **Deep behavior insights**: Uncover how agents make decisions through trace-level metric data.
* **Safety & robustness**: Detect hallucinations, toxicity, misalignment, and other failure modes early.
* **Comparative analysis**: Benchmark agent performance across runs to optimize planning logic and tool integration.
* **Customizability**: Supplement default metrics with custom ones tailored to your domain or workflow.
