 - Ragmir Core stays retrieval-first: `local-hash` supports offline retrieval, `transformers` is the explicit semantic option, and local chat remains a separate add-on.
 - Long-running Node.js processes use one `RagmirClient` per project root and close it during shutdown. Keep the top-level API for one-shot scripts.

-Ragmir is open-source local RAG for your coding agents and scripts on Node.js. It indexes the files
-selected by the project, stores the index under ignored `.ragmir/` state, and returns source-backed
-passages through a CLI, TypeScript API, or local read-focused MCP server.
+Ragmir is open-source local RAG for your coding agents and scripts on Node.js. It indexes selected
+project files on the user's machine, keeps the corpus and generated index under ignored `.ragmir/`
