Why Top AI Coding Agents Dropped Vector Databases for Grep-Based Retrieval

Major AI coding tools like Claude Code and Cursor have replaced vector databases with agentic retrieval using grep and ripgrep, achieving higher accuracy, freshness, and security; benchmarks show agentic keyword search reaches 94.5% of RAG faithfulness with zero embeddings, while Anthropic's multi-agent system beats single Opus 4 by 90.2%.
