The article explains how to assess Retrieval-Augmented Generation (RAG) projects using the Ragas automated evaluation framework, detailing four key dimensions—recall quality, answer faithfulness, answer relevance, and context utilization—and describes the underlying metrics for both retrieval and generation stages.
This article explains the evaluation pillar of context engineering, introduces the three core RAG metrics (context relevance, faithfulness, answer relevance), details the RAGAS automated assessment framework, shows how to build evaluation datasets, adopt evaluation‑driven development, and protect RAG systems from prompt injection and data leakage.
Evaluating Retrieval‑Augmented Generation (RAG) systems requires both component‑level and end‑to‑end metrics—such as context relevance, recall, answer relevance, and groundedness—and can be automated with tools like TruLens, RAGAS, LangSmith, and Langfuse, enabling systematic selection and optimization of LLM applications.
