Building effective RAG (Retrieval-Augmented Generation) systems requires careful selection and configuration of multiple interdependent components -- document converters, chunking strategies, embedding models, vector stores, and re-rankers. However, there is no standardized way to evaluate how different component combinations perform on domain-specific knowledge corpora. Our green agent provides an automated RAG evaluation benchmark that assesses participant agents across three key dimensions: 1) Retrieval Quality - ROUGE-L and BLEU scores measure how well retrieved content aligns with ground-truth answers 2) Response Coherence - Semantic coherence scoring evaluates answer quality independent of exact lexical matches 3) End-to-End Performance - Pass rate and latency metrics capture practical system effectiveness 4) Note: While our underlying agentic-rag SDK supports additional evaluation methods (METEOR, BERTScore, LLM-as-Judge), this benchmark focuses on these core metrics to provide fast, reproducible assessments. The benchmark enables researchers and practitioners to systematically experiment with pipeline configurations, comparing PDF vs. text converters, sentence-transformers vs. OpenAI embeddings, different chunk sizes, and various re-ranking strategies, to identify optimal component combinations for their specific knowledge domains. By standardizing RAG evaluation through the A2A protocol, our benchmark accelerates the discovery of best practices for building production-ready retrieval systems, reducing the trial-and-error typically required when deploying RAG applications on specialized corpora. Architecture: All pipeline configurations and computational results are persisted in a Neo4j knowledge graph, enabling participants to reuse intermediate computations (embeddings, chunked documents) across experiments. This graph-based approach provides full transparency into how documents flow through indexing and retrieval pipelines, making it easy to debug, iterate, and compare different RAG configurations. Current Benchmark Domain: The evaluation corpus consists of 100 peer-reviewed research papers on female reproductive longevity, paired with 15 expert-curated question-answer pairs designed to test both factual retrieval and reasoning across documents.
