Can the coding model replace Jev for gates?

It can approximate gates in prose, but production loops need stable types and confidence. Jev is the decision layer; the coding model stays the language/planning layer.

Jev agent skill

An agent skill is a reusable playbook: when to call Jev, which questions to ask, and how to branch. Use it in Claude Code, Cursor, Codex, or any loop that can invoke HTTP/MCP tools.

What the skill should do

Three high-ROI hooks: (1) tool-call risk gate before shell/file writes, (2) model-routing choice (fast vs frontier), (3) context keep/drop for long sessions. Each is one decide call with fixed criteria.

Minimal skill checklist

Require JEV_API_KEY, default to fail-closed on transport errors, log decision IDs, and never let the generative model rewrite your criteria map mid-flight.

Example risk gate

Send a short description of the pending action as state:

Example risk gate

{
  "state": "Agent wants to run: git push --force origin main",
  "questions": {
    "allow": {
      "type": "noul",
      "instructions": "Is this safe to auto-approve without a human?"
    },
    "risk": {
      "type": "score",
      "instructions": "Operational risk",
      "levels": 4
    }
  }
}
