It even ships a bundled rg binary via @vscode/ripgrep — you can switch to your system rg with USE_BUILTIN_RIPGREP=0 for better perf. One gotcha worth knowing: in non-git repos, .gitignore rules are silently ignored because rg doesn't pass --no-require-git by default.

Codex does as well, although I think it actually shows it running `rg`.

Oh, interesting! I had a user prompt that suggest using rg not grep, but was annoyed that it uses rg.
