 - 集成 neo4j mcp （或者自己构建工具）
 - 文档解析部分的 markdown 中的图片替换为内部可访问的链接 (2/4)
 - chat_model 的 call 需要异步
-- 优化分块儿逻辑，移除 QA 分块，集成到普通分块儿中
+- 优化chunk逻辑，移除 QA 分割，集成到普通分块中
 
 ### 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
-- 工具传递给模型的时候，使用英文，显示的时候，使用中文（尽量保持一致）
+- 工具传递给模型的时候，使用英文，但部分模型不支持中文函数名（如gpt-4o-mini）
 - 首页加载的问题
 - lightrag 类型的图谱的节点数量统计有问题
