Agent Tooling MIT E2 · source reviewed

A Rust Git semantic gate that runs as pre-commit and pre-push hooks. It reads a staged or piped diff and asks two Jev Noul questions about exposed credentials and destructive payloads; it is neither a code generator nor a conventional syntax linter.

JEV · Decision point

The reviewed revision sends up to 25,000 diff characters as state and evaluates has_secrets and has_destructive_payload in one request. It blocks at 0.80, warns from 0.55 to 0.80, and fails closed when answers, credentials, decoding, or the API are unavailable.

The project demonstrates placing Jev at an existing Git control point instead of letting a model execute Git operations. Its installer chains existing pre-commit content and adds a pre-push hook, while Git remains responsible for the actual commit and push.
