Data & Search

The live run excluded 205 reports with missing or invalid coordinates, completed **634 API calls without retries**, and reported **539,979 input tokens**. Repeated descriptions share one evaluation.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

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

Security & Guardrails MIT source reviewed

Scripts that use Jev to select CVSS metrics from vulnerability descriptions, then compute v3.0, v3.1 or v4.0 scores in Python.

JEV · Decision point

Maps attack conditions and impacts to discrete metrics; local CVSS formulas calculate the numeric score.

Exposes the selected metrics and vector alongside the final score.

I kept watching coding agents burn context on decisions that aren't hard - triage 400 tickets, tag 600 files, route to one of six teams. jev-mode moves those verdicts to a typed-judgment model. I A/B'd it: 78% fewer tokens, 16x less work-attributable input, accuracy 96.1% vs 93.7%. Python, no deps, MIT.
