Your coding agent already has your files. It greps, misses, and answers anyway. Sunstone indexes the folders you open and gives whichever model you use, Copilot's included, tools to search them properly: passages with the file and function they sit in, whole-file digests, lookups with citations, notes that survive chats. On SWE-bench Verified it names the right file first 229 of 500. Text search gets 58. Your own servers can join the picker too. It stays on your machine. Free. Source public.
