jevgrep

jevgrep lets a coding agent find code by asking what it does instead of grepping for names. Ask where the app retries failed webhooks and it returns the relevant files plus source excerpts for the agent to read. MIT, a Node CLI plus an agent skill.

It doesn't run locally. Every search sends your source to Jev, TypeSafe's hosted classification model, through Vercel's AI Gateway, OpenRouter or TypeSafe directly. Jev costs $42 per billion input tokens with output free, so the search bill itself is tiny. Declaration parsing covers Python and TypeScript/JavaScript; everything else gets a plain-text fallback.

The pitch is cheaper agent runs. On ten SWE-bench tasks the author reports the same 8 of 10 solved at 25.8% lower total cost, Jev included. Promising, but ten tasks is a small sample. Agents working in big unfamiliar repos: try it. Small repos: the README itself says ripgrep may be all you need.

The catch is where your code goes. Every query uploads source to a third-party model. For private or regulated code, that's a call for your security team, not your agent.
