它问 Jev 的问题

下面是从这个项目源码里原样取出来的 question 组合。

  state,
  questions: {
    is_urgent: { type: 'boolean', instructions: 'Does this message convey urgency?' },

  1. ambiguity打分

    How much of `prompt` would have to be guessed at before work could start?

    • 0`prompt` says what to do and where; nothing important is left open.
    • 1`prompt` leaves a detail open that a reasonable default covers.
    • 2`prompt` leaves something open that changes the result, and a wrong guess would waste the work.

  model: 'typesafe-ai/jev',
