Claude x Jev — скилл

name: claude-x-jev
description: Fast, cheap, typed decisions for Claude Code through Jev, TypeSafe's decision model on OpenRouter. Jev sorts, checks, scores, gates and verifies at 0.3 seconds and a fraction of a cent per item, with a confidence number on every answer; Claude keeps the reading, writing and judgment. Use when the user says "jev", "/jev", "/jev-setup", "/jev-classify", "/jev-check", "/jev-score", "/jev-route", "/jev-verify", "/jev-gate", "/jev-match", "/jev-tune", "/jev-lint", "/jev-bench", "/jev-watch", "/jev-status", "classify these", "sort my inbox", "triage these comments", "qualify these leads", "score these", "is this safe to run", "gate tool calls", "verify this draft", "are these the same company", "which threshold", "jev vs claude", "decision model", "openrouter decisions", or wants to run a yes/no, pick-one, or rate-on-a-scale question over many items without spending a Claude session on each one.

## What
A division of labor. Jev is a decision model: hand it choices and it picks one, with a probability on every option and a confidence number on the pick. It never writes a sentence. Claude reads, thinks, and writes. This skill puts Jev in front of Claude as the sorter, so Claude only reads what needs reading.

Measured on 216 real inbound emails (September 2026): Jev sorted them in 0.3 seconds each for one cent total. Claude Opus needed 1.3 seconds each and $4.73. They agreed on 87 to 94 percent of labels. When Jev's confidence was 0.7 or higher (82 percent of the inbox) they agreed 95.5 percent of the time. Below that, a coin flip, and Jev flagged every one.

Three primitives, every command is one of them plus a routing pattern:

| Primitive | Question it answers | Comes back |
| --- | --- | --- |
| `choice` | Which one of these? | the label, a probability per label, a confidence |
| `noul` | Does this hold? | a probability of yes |
| `score` | Where on this ordered scale? | a weighted position, a probability per level, a confidence |

## When to Use
- Many items, one narrow question each: classify, triage, qualify, rank, dedupe
- A gate in front of an action: should this tool call, send, or delete go ahead
- A check on Claude's own output before it ships: is this draft grounded, on-rules, on-tone
- Anything that has to run outside a Claude session: cron, n8n, a plain script

## Not For
- Writing anything. Jev returns labels and numbers, never prose. Drafts stay with Claude
- One item where Claude is already reading it. The win is volume and speed
- Open-ended judgment with no fixed label set. Define the labels first, then Jev

## Role
Decision-systems engineer. Turns a fuzzy "sort these" into a typed question set with thresholds, and refuses to trust a threshold that has not been checked against real data.
