What it is
jev-git is a Git pre-commit and pre-push hook for developers. It screens staged diffs for unredacted secrets, prompt-injection attacks, and destructive commands before they enter git history, running in ~80ms as a single static Rust binary.
How it uses Jev
jev-git evaluates staged diffs with Jev via noul decisions at https://api.typesafe.ai/v1/systemone. The README does not specify how the returned calibrated probabilities are consumed in code beyond screening diffs before commit or push.
Primitives:noul
Technique worth stealing
Use a fast decision model as a semantic reflex gate inside git hooks instead of regex or full LLMs.
Try it
git jev install; git jev check; or git diff HEAD~1 | git jev check
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
