This hooks up Claude to CocoIndex Code's semantic search engine for your codebase. Instead of grepping for string matches, you search by concept ("authentication flow", "retry logic") and get back ranked chunks, file summaries, and curated architecture guides. Claude owns the full lifecycle: it'll auto-initialize, keep the index fresh after refactors, and follow hints in search results to pull up summarized APIs or cross-cutting design docs. The real win is when you're dropped into an unfamiliar repo and need to understand "how does memoization work here" without reading fifty files. It's opinionated about not spamming describe or guide commands until search tells you to.
