+**重要说明：**
+1. **relationships数组必填**：至少要有1-3个与已有角色的关系（除非确实没有合理的关联）
+2. **target_character_name必须精确匹配**：只能引用【已有角色】列表中的角色名称
+3. organization_memberships只能引用已存在的组织名称
+4. intimacy_level是-100到100的整数：
+   - 80-100：至亲、挚友、深爱
+   - 50-79：亲密、友好
+   - 0-49：一般、普通
+   - -1到-49：不和、敌视
+   - -50到-100：仇恨、死敌
+5. loyalty是0-100的整数（仅用于组织成员）
+6. status默认为"active"，表示当前关系状态
+
+**关系建立示例：**
+- 如果新角色是主角的新队友，应该与主角建立"队友"或"朋友"关系
+- 如果新角色是反派的手下，应该与反派建立"上司-下属"关系
+- 如果新角色与某角色有血缘，应该建立家族关系
