  "account": "Technical Briefing: In the realm of Agentic Workflows at Gate of AI, this tutorial delves into the trade-offs between precision and breadth in retrieval-augmented generation systems. While retrieval can enhance precision and metadata completeness while diminishing breadth, research evidence suggests that RAG does not universally improve every quality dimension, task, or model. A June 2025 research paper, \"Reasoning with RAGged events: RAG-Enhanced Event Knowledge Base Construction and reasoning with proof-assistants,\" compares direct generation, knowledge-graph enhancement, and RAG for extracting structured historical events from narrative texts. The findings reveal that RAG optimizes different performance dimensions. Direct generation excels in coverage and historical breadth, while RAG improves precision, coordinate accuracy, and metadata completeness, albeit at the cost of reduced breadth. Therefore, teams planning a knowledge base should focus on identifying the most critical failure to address – imprecision, missing coverage, incomplete metadata, or inconsistent behavior – to shape evaluation, retrieval policies, and acceptable trade-offs.",
