"""AI 辅助创建（小白友好）：大白话 → 结构化草稿 + 资源冲突检测。
|
|||
|
|
|
|||
|
|
两个能力：
|
|||
|
|
1. draft_from_blab：用户用自己的话描述「我想要一个干什么的 Agent / 技能 / 模板」，
|
|||
|
|
由当前默认模型解析成结构化草稿（名称/说明/规则/指令/提示模板字段），
|
|||
|
|
用户在表单里确认修改后再正式创建——AI 只出草稿，不直接落库。
|
|||
|
|
2. conflict_scan：创建/修改前的冲突检测，回答「Agent、技能、模板之间会不会打架」：
|
|||
|
|
- 重名/高相似名称
|
|||
|
|
- 同名约束互相矛盾（规则 vs 技能 vs 模板约束）
|
|||
|
|
- 关键词互斥（如「口语化」对「书面语」「输出 JSON」对「段落正文」）
|
|||
|
|
|
|||
|
|
冲突不阻断创建，返回 warning 列表由前端展示，用户判断后可继续。
