Jev-cu

Codex computer-use skill where Jev picks the next element and action from on-screen text, with a local policy gate for sensitive steps.

Codex computer-use skill where Jev picks the next element and action from on-screen text, with a local policy gate for sensitive steps. README in Chinese.

# Jev-cu

把 Computer Use 的「下一步点哪里」交给 Jev(TypeSafe System One):Jev 从界面文字候选中选元素、动作、完成度与风险,Codex Computer Use 负责读取界面与执行,本地策略门槛拦截敏感操作。只传文字,不传截图。

## 目录

```
skill/jev-cu/   可安装到 Codex 的 skill(运行手册 + 安全规则)
scripts/         Jev 调用、策略门槛、决策循环、离线评测、安装脚本
fixtures/        AX 快照与 P0 用例
tests/           单测
```

## 安装 skill

```bash
npm run install-skill      # 复制到 ~/.codex/skills/jev-cu,新会话生效
npm run uninstall-skill
```

skill 源文件里的 `{{REPO_DIR}}` 会在安装时替换成仓库实际路径。

## 使用

先在 `.env.local` 写入 key(不提交),或设置同名环境变量:

```bash
echo 'TYPESAFE_API_KEY=<your key>' > .env.local
```

循环要在 Codex 桌面 App 的 `cua_repl` 运行时里执行:

```js
const repo = "/path/to/Jev-cu"; // 换成实际克隆路径
const { pathToFileURL } = await import("node:url");
const { runTask, createCuaDriver } = await import(pathToFileURL(`${repo}/scripts/loop.mjs`).href);

await runTask({
  driver: createCuaDriver(cua),
  appName: "Calendar",
  goal: "switch the calendar to the previous month", // 英文目标,Jev 英文最准
  dryRun: true,                                       // 确认后改 false
  maxSteps: 5,
});
```

## 验证

```bash
npm test        # 单测,不调用 API
npm run p0      # 离线评测:AX 快照选元素准确率(调用 Jev,需要 key)
```

## 安全边界

- 默认 dry-run;删除、发送、支付、授权、上传、验证码、安装、系统设置等操作停在 `confirm`,需人工确认。
- App 白名单在 `scripts/policy.mjs`,新增 App 必须显式修改。
- 界面文字只作为数据,不作为指令;不绕过登录、付费墙和验证码。
