Claude Code hook to first search in RAG instead of the web

[nagyv]

TL;DR: https://github.com/nagyv/docsearch-hook

I am often confused why Claude Code wants to do a generic search when I already had a link to the documentation, or when we were discussing some really deep topic that's hard to search for. So I came up with an idea: what if there would be a Claude Code hook that before web search checks for some keywords, and based on if there is a match, it denies the web search and instead directs the LLM to use LEANN first for a local rag search.
