提示示例
配置好后，你可以这样和 AI 对话：
查询配置：
帮我获取 Nacos 中 dataId 为 "application.yaml" 的配置
查看 nacos 里 user-service.yml 的配置内容，namespace 是 dev
获取 gateway 的配置，分组是 PROD_GROUP
发布配置：
把下面这段配置发布到 Nacos，dataId 是 "redis.yaml"：
server:
port: 6379
更新 user-service 的配置，把数据库端口改成 3307
只读模式
设置 NACOS_READ_ONLY=true 可以禁用发布功能，只允许查询配置。适合生产环境使用。
