What it is
A pre-commit hook for developers and agents: it checks whether the commit message matches the staged diff, flags debug leftovers and unmentioned work, and blocks only on a detected credential.
How it uses Jev
One Jev request asks five noul questions about the message and staged diff together: message is filler, contradicts the diff, debug leftovers, unmentioned work, secret shaped. The match answer combines by min, the three findings by max; code owns thresholds and the decision.
Primitives:noul
Technique worth stealing
One Jev call judges five typed questions in isolation against the same state, so code can threshold calibrated probabilities instead of parsing text.
Try it
Add the pre-commit snippet, run pre-commit install --hook-type commit-msg, or pipx install and write a commit-msg hook.
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.
