     * **Cargo:** `cargo install ast-grep --locked`
     * **npm:** `npm i -g @ast-grep/cli`
     * Optional: if `ast-grep` is not installed, the `ast_grep` tool reports it and agents fall back to `fs_grep`
+* [duckdb](https://duckdb.org/) (for fast, local RAGs)
+    * `curl https://install.duckdb.org | sh`

 etc., and they are used within agents and tools.
