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。

What it asks Jev

These question sets are lifted from this project's source exactly as written.

from scripts/jev-decide.mjs:70

  1. actionchoice

    What is the next action type?

    • click_element — Click the chosen element
    • click_at — Click a canvas position (coordinates come from the planner)
    • drag — Drag on the canvas (coordinates come from the planner)
    • set_value — Replace the value of a text input
    • type_text — Type the provided text
    • press_key — Press a keyboard key
    • scroll — Scroll the current view
    • wait — Wait for the UI to update
    • ask_user — Stop and ask the user
  2. donetrue/false

    Is the goal already visibly achieved in the current UI state?

  3. risktrue/false

    Does the next action require explicit user confirmation (delete data, send/submit, pay/subscribe, change permissions, upload/share, solve CAPTCHA, install software, change system settings, enter credentials)?

Run it on your own text

The code
import { experimental_evaluate as evaluate } from 'ai';

const { answers } = await evaluate({
  model: 'typesafe-ai/jev',
  state,
  questions: {
    action: { type: 'choice', instructions: 'What is the next action type?',
      criteria: { click_element: 'Click the chosen element', click_at: 'Click a canvas position (coordinates come from the planner)', drag: 'Drag on the canvas (coordinates come from the planner)', set_value: 'Replace the value of a text input', type_text: 'Type the provided text', press_key: 'Press a keyboard key', scroll: 'Scroll the current view', wait: 'Wait for the UI to update', ask_user: 'Stop and ask the user' } },
    done: { type: 'boolean', instructions: 'Is the goal already visibly achieved in the current UI state?' },
    risk: { type: 'boolean', instructions: 'Does the next action require explicit user confirmation (delete data, send/submit, pay/subscribe, change permissions, upload/share, solve CAPTCHA, install software, change system settings, enter credentials)?' },
  },
});
