 ## Unreleased
 
++ [优化] Agent 动态工具卡片显示具体工具名称、准确执行状态和失败原因，避免统一显示为含糊的「工具操作」。
 + [修复] 画布 Agent 默认通过画布节点生成内容，仅在用户明确指定时使用 Codex 内置生图并将结果展示到对话和当前画布。
 + [优化] Agent 面板标题、功能标签与新对话操作合并为单行顶部栏，减少面板空间占用。
 + [新增] 画布 Agent 支持请求批准、自动审查和完全访问三档 Codex 权限，并可在对话中审批文件、命令与网络访问。

 # 待测试
 
+- Agent 动态工具信息：执行内置生图、查看图片、命令、文件修改或其他动态工具时，卡片标题应显示具体工具名称；执行失败时正文应显示真实错误原因，刷新并恢复历史对话后仍应保持一致，不再统一显示「工具操作已完成」。
 - Agent 画布生图：重启 Canvas Agent 后，其自动生成的工作区 `AGENTS.md` 应同步为最新版指令（用户自行编写的其他 `AGENTS.md` 不应被覆盖）；输入“生成一张图片”时应调用 `canvas_generate_image`，通过当前画布节点创建并运行生成流程；只有明确输入“使用 Codex 内置生图/ImageGen 技能生成”时才允许调用内置能力，Codex App Server 返回的 `imageGeneration` 结果应显示在对话中并作为保持原比例的图片节点添加到当前画布；Agent 不应在没有生成结果时提前声称“已生成”。
 - Agent 顶部栏：标题只显示垂直居中的「Agent」，连接、对话、历史、日志、新对话和收起操作应位于同一行；面板较窄时标签仍可横向滚动且操作不应错位。
 - Agent Markdown 样式：右侧 Agent 回复中的代码块应为横向占满消息区域、无语言标题和无双层边框的紧凑代码条，单行内容不应保留纵向大面积空白，复制操作仅在悬停时弱化显示；行内代码、链接在浅色和深色主题下应清晰；点击外部链接后应显示中文紧凑确认弹窗，长路径能够正常换行且复制、继续打开和关闭操作可用；点击 `/Users/`、`/home/` 等本地绝对文件路径时应改为提示在系统文件管理器中定位，支持复制路径，且浏览器地址不应跳转为 localhost 文件路径。
