 - 同名文件处理逻辑：遇到同名文件则在上传区域提示，是否删除旧文件
 - conversation 待修改为异步的版本
 - DBManager 需要将数据库修改为异步的aiosqlite或者异步mysql，缓存使用Redis存储
+- 【eval】缺少自动生成评估的功能
 
 ### Bugs
 - 部分异常状态下，智能体的模型名称出现重叠[#279](https://github.com/xerrors/Yuxi-Know/issues/279)
 - DeepSeek 官方接口适配会出现问题
 - 目前的知识库的图片存在公开访问风险
 - 深度分析智能体需要考虑上下文超限的问题
+- 【eval】检索评估缺少检索参数的内容
+- 【eval】总体评分替换为确定的某个指标，最好是在右侧可以选择可行的指标
+- 【eval】检索配置应该修改为一个弹窗
+- 【eval】当前的检索配置仅保存在本地，实际并没有保存在知识库的元数据中
 
 ### 新增
 - 优化知识库详情页面，更加简洁清晰
