jevgrep jevgrep
jevgrep is a research CLI that helps AI coding agents find relevant code by asking what it does. The `jg` command uses TypeSafe's Jev model to judge relevance across folders, files and declarations, then returns relevant files, reading leads and verbatim source excerpts in a single stdout response. A bundled agent skill teaches Claude Code, Codex and other agents to use it for context gathering before they implement changes.
The repository was created on September 26, 2026, reached more than 1,000 GitHub stars within two days, and shipped releases through v0.4.3 on September 28; the author announced it on X as a Jev-powered research agent CLI.
As of
- Natural-language repository questions answered with files, leads and verbatim excerpts
- Jev-based relevance judgments across folders, files and declarations
- Installable agent skill (`jg skill`) for coding agents
- Provider selection across Vercel AI Gateway, TypeSafe, OpenRouter and OpenCode Zen
- npm-distributed CLI for macOS and Linux with no separate ripgrep, Python or Bun install
Developers whose coding agents spend many tokens exploring unfamiliar repositories and who want a cheaper context-gathering step.
Cases where the exact symbol or string is already known and plain text search is faster, teams that cannot send source excerpts to a hosted model provider, or native Windows users.
jevgrep is free and open source under the MIT license. Searches call the Jev model through a provider key you supply (Vercel AI Gateway, TypeSafe, OpenRouter or OpenCode Zen), and that provider bills inference usage.
A focused context-gathering tool for coding agents built on Jev. Its reported cost reduction comes from the author's own ten-task SWE-bench comparison, so results on other codebases may vary.
