Jevbridge — tacticocc

An ACP and MCP adapter that bridges TypeSafe Jev with any LLM: native Jev when TYPESAFE_API_KEY is set, or Codex, Claude, Grok, OpenCode, and OpenAI-compatible endpoints standing in as System One when it is not.

Highlights

  • Swaps backends (jev, llm, heuristic, auto) without changing question shapes, and the heuristic backend runs offline in tests and CI.
  • Speaks MCP (jev_decide, jev_gate, jev_computer_use) and ACP over stdio for Zed, JetBrains, and other hosts.
  • Confidence gates return execute, confirm, escalate, or abort for tool calls and computer-use clicks.
  • Ships recipes for support routing, destructive-command gates, context keep/drop, and GUI next-action.
  • The heuristic scorer includes question text in its evidence, so its numbers are a smoke test, not a safety signal.

Quickstart

ts
import { evaluate, choice } from "./src/index.ts";
const result = await evaluate({
  state: "I was charged twice for order A-104. Refund the duplicate today.",
  questions: {
    team: choice("Which team should handle this?", {
      billing: "Payments, invoices, refunds.",
      technical: "Bugs, outages, integrations.",
      other: "None of the above.",
    }),
  },
  backend: "auto",
});

Watch out

MIT-licensed. A zero-dependency Node 22 library, but requires Node.js 22 or newer; native Jev needs a TypeSafe API key, and with no key auto falls back to the local keyword scorer.
