WHY I'M AGAINST CLAUDE CODE'S GREP-ONLY RETRIEVAL? IT JUST BURNS TOO MANY TOKENS

Summary from the TLDR AI newsletter

AI coding assistants still don't agree on the best method for searching codebases for context. There are currently two approaches: vector search-powered RAG and keyword search with grep. While grep is fast, exact, and predictable, it drowns users in irrelevant matches, burns tokens, and stalls workflows. Vector search-based RAG makes search dramatically faster and more accurate, and it reduces token use by 40% or more.
