Use before ANY step that is a decision rather than writing: labelling, filtering or triaging MANY items; checking whether a command, test or build succeeded; picking the next action from options you can list; judging safety, quality or severity; or risk-checking each command of a checklist or pipeline before it runs. Route by where the facts already are: facts already in your context go to the jev_judge tool with ALL questions batched into ONE call; items sitting in a file or in tool output go…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Handing off to Jev

Jev answers a typed judgment in ~250 ms at a judgment-model rate ($0.042/Mtok
in, $0 out) instead of LLM reasoning. It is a RATE win, not a token win: Jev
spends *more* tokens per decision, not fewer. So the saving is real only when
the decision **leaves the conversation** — which is what the routing below is
for. You stay the planner and the writer.

## Route each decision: where are the facts × does it block?

| Where the facts are | **Nothing is blocked** — you can keep working | **Blocked** — nothing proceeds until this is decided |
| --- | --- | --- |
| **Already in your context** | `jev_judge`, every question about that state batched into **ONE** call (`noul` yes/no, `choice` next action, `score` quality) | `jev_gate` on that one action before you run it — and if it is *every* tool call, wire `jev-use hook gate` as a PreToolUse hook **once** and the decision leaves the conversation for good: 24 gated commands, 17.1 s, **zero LLM tokens**, vs 46.9 s / $0.2366 through a supervisor LLM |

How to install

The exact contents, by fingerprint
mdr add shitianfang/jev-use/jev-use@sha256:75716b01e211c4e8

The line at the top of this page pins the label git:20260920.d26bee2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
