This article provides a comprehensive technical analysis of Retrieval-Augmented Generation (RAG), covering embedding principles, chunking strategies, vector databases, dense/sparse/hybrid retrieval, reranking, HyDE, GraphRAG, and engineering evaluation frameworks with code examples.
The article debunks claims that vector databases are obsolete, analyzing how Claude Code and Cursor integrate retrieval into agent runtime loops rather than abandoning RAG, and proposes a five-layer architecture where vector indexes serve as retrieval projections alongside grep, semantic search, and authoritative sources.
Anthropic removed vector search from Claude Code in 2025, replacing it with grep and finding it outperformed RAG by a wide margin; Cursor, Windsurf, and others followed. Benchmarks show agentic keyword retrieval achieves 94.5% of RAG's faithfulness with zero vector databases, while multi-agent systems beat single models by 90.2%. The shift moves retrieval from pre-computed indexes to just-in-time tool use, though vector search remains for semantic queries and massive stable corpora.
