CLI & Pipelines MIT E1 · source linked

Ranks text along a plain-English criterion using pairwise Jev Noul comparisons and a locally fitted Bradley-Terry scale.

JEV · Decision point

Jev judges whether text A ranks higher than text B on the supplied criterion; local code schedules comparisons and fits a Bradley-Terry scale with standard errors.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

Decision Tools MIT E1 · source linked

A Claude Code Stop hook that reads the turn transcript locally and calls Jev only when files changed and no check has passed, blocking an unverified “done”.

JEV · Decision point

Four questions: whether the closing message claims done, claims checks passed, whether verification applies, and a complete / partial / blocked / other choice.

Skips the model when a check already passed; every error path lets the turn end.
