# First-Time Setup

## ⚠️ 重要：必须询问用户选择！

- **禁止**：直接使用默认选项而不询问用户
- **禁止**：跳过设置步骤直接生成
- **必须**：用 AskUserQuestion 让用户选择每个选项
- **必须**：等用户确认后再保存 EXTEND.md

## Overview

Triggered when:
1. No EXTEND.md found → full setup (provider + model + preferences)
2. EXTEND.md found but `default_model.[provider]` is null → model selection only

## Setup Flow
