jev-commit

A pre-commit hook that answers five Jev questions about the commit message and staged diff together, warning on mismatches and blocking only on a credential-shaped line.

Highlights

  • Five questions in one request flag filler messages, claims absent from the hunks, debug leftovers, unmentioned work, and secret-shaped values.
  • Over a 152-commit corpus the median cost was $0.000044 per commit, about four cents per thousand commits.
  • Warnings never block; only a credential on an added line stops the commit, and --strict blocks on findings past the threshold.
  • Needs pre-commit install --hook-type commit-msg, since a plain pre-commit install will not run it.
  • Python 3.10+ with no dependencies, and the hook itself takes 240 ms median, 21 ms of it a loopback call.

Quickstart

bash
pipx install git+https://github.com/valentynkit/jev-commit
printf '#!/bin/sh\nexec jev-commit "$1"\n' > .git/hooks/commit-msg
chmod +x .git/hooks/commit-msg

Watch out

MIT-licensed. Needs a TypeSafe API key, and pre-commit refuses to install while core.hooksPath is set, so the hook must be added by hand there.

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x

Fast browser use with Stagehand

we built blazing fast computer/browser use with Jev + @Stagehanddev. this task cost $0.001 and executed at near instant speed (in a remote browser btw) the loop: observe the page, send a11y tree as state + actions as questions, Jev decides the next action, then Stagehand Show more

LLM-as-a-judge, sped up

Jev has spoken. It picked which model is AGI. 20–200x faster. 40–400x cheaper. This could make things like LLM-as-a-judge insanely fast and nearly free. (I tried a bunch of prompts and still didn’t burn through $0.10.)
