 - 不要硬编码黑白、stone、slate 等颜色导致浅色/深色主题不一致。
 - 新增画布按钮、弹窗、浮层时，尽量复用已有工具栏、节点面板、Modal 的视觉风格。
 - 画布顶部工具栏和状态信息优先采用极简扁平风格：无边框、无阴影、无胶囊背景，融入整体背景，弱化按钮感，仅保留轻微 hover 反馈，保持简洁现代、低视觉重量。
+- 左侧画布面板等列表里的节点/元素缩略图容器，非图片类型（文本、配置、视频、音频等）不要使用 `theme.node.fill`（`#e7e5df`/`#292524`）这类灰色背景，图标直接无背景展示，尽量不要给多余底色，保持干净。
+- 画布内的操作按钮（如面板里的「添加」「导出」「选择」等）默认用扁平无底色样式：透明背景、仅 `hover:bg-black/5 dark:hover:bg-white/10` 轻微反馈，靠图标+文字表达，不要用 `theme.toolbar.activeBg`（`#e7e5df`/`#3a3631`）或 `theme.node.fill` 之类的灰色作为按钮填充底色。灰色 `activeBg` 只允许用于「选中态」等需要表达状态的高亮，不要当普通装饰底色。
 - 图片节点尺寸逻辑要尊重原始比例，除非功能明确要求自由变形。
 - 批量生成、多图展示、助手面板等画布交互要尽量简洁，不要占用过多画布空间。

+- 修改当前画布时根据任务使用已配置的 infinite-canvas MCP 工具；复杂批量改动使用 `canvas_apply_ops`。

 # 待测试
 
-- 画布节点插件系统:内置节点(图片/文本/视频/音频/配置/组)改为统一注册表管理,创建菜单由注册表动态生成;需验证六种内置节点的创建、渲染、缩放、连线、小地图颜色、作为生成输入等行为与之前一致。内置节点仅这六种,其余均为插件。
+- 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”。
-- 画布节点插件系统:左上菜单新增「节点插件」,可通过 URL 安装远程插件、启用/禁用、更新、卸载;安装时有安全警告说明插件代码在页面内执行、可访问本地数据。可用 `/plugins/sticky-note.js` 安装便利贴节点验证:换色、编辑、「衍生文本节点」(演示 applyOps 增节点+连线)。
+- 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。
-- 画布节点插件系统:示例插件 Markdown(编辑/渲染)、HTML(沙箱 iframe 渲染,支持 {{input}} 注入上游文本)、SVG(渲染/编辑,可取上游文本 SVG 源码)、3D 全景(three.js CDN 动态加载,可从上游图片节点取全景图并拖拽查看);均为远程插件,需分别安装 `/plugins/markdown.js`、`/plugins/html.js`、`/plugins/svg.js`、`/plugins/panorama.js` 后验证创建、渲染、编辑及与上游节点的交互。
+- 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。
-- 画布节点插件系统:卸载或禁用插件后,画布上遗留的该类型节点显示「缺少插件」占位且数据保留,重新安装/启用后恢复渲染;需验证刷新后已启用插件自动加载。
+- Agent 工具确认模式：右侧面板标题栏不应再显示「工具确认」开关；对话输入框左下方应显示确认模式选择，默认选中「自动确认」，画布写入工具应直接执行；切换为「手动确认」后，画布写入工具应在对话中展示等待确认卡片，并支持批准或拒绝。
-- 画布节点插件系统:每个插件为 `plugins/canvas/<name>/` 独立目录(各自 package.json + esbuild + src + README,互不耦合),`npm run build` 产物落到 `dist/<name>.js` 并同步到 `web/public/plugins/`;需验证各插件可独立构建与安装。
+- Canvas Agent Codex 升级：启动 Canvas Agent 后应能正常连接 Codex、创建或恢复会话、发送消息并调用画布工具，实际运行的 Codex CLI 版本应为 0.145.0；运行中停止任务应只中断当前 turn，随后无需重启 Agent 即可继续发送新任务。
-- 画布节点插件本地开发:每个插件支持 `npm run dev`(watch 自动构建并同步到 `web/public/plugins/`),配合 `web/.env.local` 的 `VITE_DEV_PLUGINS`(逗号分隔 URL)每次刷新重新拉取、无需反复安装;需验证改源码刷新页面即生效。
+- Canvas Agent Debug：使用 `npx -y @basketikun/canvas-agent --debug` 启动后，终端应按“时间 级别 消息 详情”的纯文本单行格式输出日志并显示日志文件路径，`~/.infinite-canvas/logs/` 下应按启动日期生成相同格式的 `canvas-agent-YYYY-MM-DD.log`，同一天多次启动应追加到同一文件；普通启动保持原有简洁输出，日志中不应出现连接 token 或图片 Data URL 原文。
-- 画布节点创建:鼠标左键双击画布空白区域会在点击位置打开节点选择菜单,可创建文本、图片、视频、音频、生成配置和组节点;双击已有节点或连线不应触发菜单。
+- Agent HTTP 诊断日志：网页发送一条普通消息后，本地 Debug 日志不应重复输出 `/health`、`/canvas/state`、`/canvas/activate` 成功请求、流式增量或完整会话响应，只保留 HTTP 请求与 Codex 生命周期摘要；右侧「日志」应以单行时间线展示发送、开始、回复、工具、完成用量和错误，不再输出 userMessage started/completed、流式摘要、重复 threadId 或大段原始 JSON。
-- 本地 Agent 连接说明：新增提醒说明只有安装 Codex 插件或手动添加 MCP 后才会增加 Codex token 消耗，直接运行 `npx -y @basketikun/canvas-agent` 不会安装 MCP；需验证文案位置清晰。
+- Agent 对话统计：用户消息应右对齐并使用透明无气泡的简洁排版，用户和 Codex 两侧均不显示人物头像，消息下方均不显示时间或 Token 信息；输入框上方应居中展示最新一次模型调用的输入、缓存、输出 Token 用量，不显示会话累计值，数值更新时应从旧值平滑滚动到新值而非突然跳变，新建、切换或删除当前会话后应清空旧统计。
-- 本地 Agent 连接说明：画布面板和配置页 Codex Tab 改为区分“Codex 插件启动画布”和“直接运行 Agent 后网页连接”两种方式，需验证文案和布局清晰。
+- Agent 回复实时显示：在右侧 Agent 发送消息后，用户消息下方应立即出现“正在思考...”，任务运行期间不应闪退；工具完成后应显示 Codex 正在继续处理及已等待时长，等待超过 30 秒时提示可继续等待或停止本轮；Codex 的回复应在当前对话中持续显示，实时事件缺失时也应在任务完成后自动同步完整内容，无需切换到历史或日志再返回对话。模型繁忙等任务失败时应立即结束等待状态，在对话中显示中文错误原因和重试建议，诊断日志不应再把失败轮次记为“处理完成”，刷新历史后错误仍应保留。新建尚未发送首条消息的空会话不应反复出现历史读取失败。
-- 全站 Agent：Agent 面板从画布页抽离为全站常驻面板，挂在全局布局右侧，开/关只挤压左侧内容不遮挡；顶栏和画布工具条各有一个开关按钮，需验证在首页、生图、视频、素材、提示词库、画布等页面都能打开面板并保持 SSE 连接不断开。
+- Agent 流式交互性能：发送长回复时文字应连续平滑出现，输入框、滚动和画布操作不应随回复变长而明显卡顿；长历史会话中只有当前流式消息持续更新，屏幕外消息不应造成明显布局压力；任务完成后应通过 SSE 自动同步完整历史，不再持续请求 `/health` 轮询状态。
-- 全站 Agent：新增 `site_navigate` 工具，Agent 可直接跳转 `/`、`/canvas`、`/canvas/:id`、`/image`、`/video`、`/prompts`、`/assets`、`/config`；导航直接执行不走工具确认，需验证跳转正确且面板不消失。
+- Agent 过程时间线：新建 Agent 对话后 Codex 应生成可读思考摘要，并在运行时依次显示中文的思考摘要、执行计划、命令执行、网页搜索、文件修改和画布工具活动；思考摘要的图标、标题和箭头应稳定保持在同一行，默认收起且无边框，点击箭头后才展开 Codex 实际返回的具体摘要，其中 Markdown 强调、列表和代码应正确渲染而非显示原始符号，完成事件不应再用「已完成分析」覆盖已经收到的摘要；命令执行也应使用无边框紧凑行，显示「已执行 1 条命令」和单行命令预览，点击后再展开工作目录、耗时、退出状态和运行输出；其他工具调用继续使用紧凑卡片排版，状态图标、标题和状态文字保持在同一行；结构化任务进度不应混在对话时间线中，而应独立放在对话区下方、Token 统计上方，支持展开和折叠，并逐项实时更新「待处理」「进行中」「已完成」状态；新任务生成时默认展开，任务结束后保留最新结果，同一计划更新不应生成重复内容；文件详情展示文件路径与新增/修改/删除动作，工具详情不应出现请求 ID、英文工具名或原始 JSON；一轮对话结束自动同步历史以及刷新页面后从历史中 resume 对话时，思考摘要、命令和工具过程记录仍应完整保留并保持相同展示。
-- 全站 Agent：画布工具（canvas_apply_ops 等）仅在当前处于画布页时可用，不在画布页调用会返回“当前不在画布页，请先用 site_navigate 打开画布”，需验证 Agent 会先导航到画布再执行画布操作。
+- Agent 权限控制：输入框可选择「请求批准」「自动审查」「完全访问」；请求批准模式下，Codex 编辑工作区外文件、执行受限命令或访问网络时应在对话中显示审批卡片，支持拒绝、允许一次和本会话允许，并能依次处理多个并发请求；自动审查模式应仅将需要用户决定的风险操作送入审批；完全访问必须先显示风险确认，启用后可访问网络和本机文件且不再请求审批；选择应在刷新后保留。
-- 全站 Agent：Codex 会话改为单一站点级连续线程（不再按 canvasId 分），跨页面/跨画布保持同一条对话上下文，历史记录即这条线程；本地 Agent workspace 从按画布分改为固定 `site` workspace（`~/.infinite-canvas/codex-workspaces/site`），已装 `@basketikun/canvas-agent` 的用户需更新到新版本才生效。
+- Agent 历史记录：点击记录卡片应直接进入对应对话，不再显示「进入」按钮；可勾选单条或全选多条记录并批量删除，删除当前对话后聊天内容应清空。
-- 全站 Agent：移除仅前端调用 OpenAI responses 接口的在线画布助手死代码（含 `requestToolResponse`），Agent 统一走 MCP + 本地 Codex 链路。
+- Agent 默认新对话：每次进入任一画布并连接 Agent 后，对话区应保持空白且不自动恢复上一次会话；第一次发送消息时才创建新线程，不应产生未发送消息的空历史记录；需要继续旧对话时可在「历史」中主动选择恢复。
-- 画布节点名称：每个节点保留 `title` 名称字段，默认名称显示在节点上方，双击名称可直接编辑，节点信息弹窗和 JSON 可查看该字段。
+- Agent 当前画布优先：在已打开某个画布时要求 Agent 创建、修改、整理或生成内容，Agent 应直接读取并操作当前画布，不应先调用 `canvas_list_projects` 或使用 `site_navigate` 重复进入画布；只有明确要求查看或切换其他画布时才允许查询画布列表并导航。
-- 画布节点工具条：节点顶部工具条改为点击选中节点后显示，单纯鼠标移入 / 移出节点不应再频繁弹出。
+- Agent 图片消息：发送一张或多张图片附件后，图片应紧跟用户文字并在消息右侧显示为约 40px 的紧凑缩略图，不再撑大消息区域，单击缩略图应打开大图预览，打开或关闭预览不应改变消息间距或产生额外空行；任务运行中、完成同步历史、切换页面及重新进入历史对话后都应显示浏览器本地保存的图片缩略图，不应消失或把 attachmentId、附件使用说明等内部上下文回显到用户消息中；删除历史会话后应同步清理对应缩略图。
-- 画布组节点：组内子节点优先响应点击和拖拽；当鼠标位于组内节点上时，应移动 / 编辑该节点，而不是移动整个组。
+- 画布文本复制：在 Agent 对话或节点信息详情中用鼠标选中文字后，按 `Ctrl/Cmd + C` 应复制所选文本，不应触发画布节点复制；未选中文字且焦点位于画布时，原有节点复制快捷键应保持可用。
-- 画布组节点：工具栏新增“组”节点，普通节点拖入组区域会高亮目标组，松手后自动吸附进组；拖出组区域会解除归属，拖动组节点会一起移动组内子节点。
+- Agent 工作目录指令：`canvas-agent/agent-instructions.md` 应作为独立维护源；重启 Canvas Agent 后，当前工作目录应自动生成 `AGENTS.md`；新建对话发送消息时，Codex 日志中的用户消息只包含本轮请求和必要的附件上下文，不再重复整段 Infinite Canvas 前置提示词，画布及工作台工具仍可正常调用。
-- GitHub Pages：新增版本 tag 触发的前端静态站点自动发布 workflow，需在仓库 Pages 设置中选择 GitHub Actions 并验证路由刷新回退。
+- 画布文本设置：文本节点和生成配置节点切换到文本模式后应显示推理强度设置，可选择自动、低、中、高、极高；选择自动时默认 OpenAI Responses 请求不应携带 `reasoning`，选择其他档位时应携带所选强度，刷新画布后节点设置应保留；文本模型自定义调用脚本应能读取 `reasoningEffort`，OpenAI 模板应按自动或指定档位正确组装请求。

+title: 提示词面板引用显示图片缩略图规划
+description: 将提示词面板输入框从 textarea 改造为 contentEditable，让 @ 引用直接显示真实图片缩略图
+---
+
+# 提示词面板 @ 引用显示真实图片缩略图
+
+## 背景 / 要解决的问题
+
+提示词面板（`CanvasNodePromptPanel`）的输入框里，`@` 引用一张图片后，显示的是蓝色文字 chip「图片1」。期望**直接显示这张图片的真实缩略图**，而不是文字编号。
+
+当前该输入框是原生 `<textarea>`，只能承载纯文本，无法内嵌图片。要显示缩略图，必须改用 `contentEditable`（可编辑 div），把引用做成带 `<img>` 的原子小卡片。项目里「组装提示词」组件（`CanvasConfigComposer`）已经是这套 contentEditable + 图片 chip 的成熟实现，可作蓝本。
+
+## 关键约束（为什么不能直接改现有组件）
+
+`CanvasResourceMentionTextarea` 被两处复用：
+
+1. **提示词面板** `web/src/components/canvas/canvas-node-prompt-panel.tsx` —— 本次要改的对象。`highlightLabels` 默认 true，value 是提示词字符串，引用以 label 文本「图片1」嵌在其中，**直接发给 AI**（配合 `web/src/lib/image-reference-prompt.ts` 的「参考图片编号：图片1」前缀）。
+2. **节点内文本编辑** `web/src/components/canvas/canvas-node.tsx`（`isEditingContent` 分支）—— `highlightLabels={false}`，通过 `ref` 调用 `textarea.setSelectionRange(...)` 等 **textarea 专有 API**。若把组件改成 contentEditable，这处会直接崩。
+
+> 结论：**新建一个 contentEditable chip 输入组件，只替换提示词面板那一处**；`CanvasResourceMentionTextarea`（textarea 版）保持不动，继续服务节点内文本编辑。
+
+## 方案：新增 `CanvasPromptChipInput` 组件
+
+新文件 `web/src/components/canvas/canvas-prompt-chip-input.tsx`，参照 `canvas-config-composer.tsx` 的 contentEditable 模式，但有一处**核心差异**：
+
+- 「组装提示词」把引用序列化成 `@[node:UUID]` 标记；
+- 本组件的 value 必须保持**引用的 label 文本**（如「图片1」），这样发给生成的提示词语义不变。因此 chip ↔ 文本的序列化用 **label 文本**，不是 node 标记。
+
+### 组件契约（与现用法一致）
+
+Props：`value: string`、`references: CanvasResourceReference[]`、`onChange(value)`、`onSubmit?()`、`className`、`style`、`placeholder`。图片缩略图取 `reference.previewUrl`（即 `node.metadata.content`，已存在于 `CanvasResourceReference`）。
+
+### 实现要点（大量复用 composer 的做法）
+
+1. **DOM ← value（未聚焦时重建）**：仿 `CanvasConfigComposer` 的重建 effect。用 active label 列表（`references.filter(active).map(label)`，按长度降序）把 value 字符串切成「文本片段 + 命中 label」，命中处插入 chip。聚焦时不重建（`document.activeElement === editor` 直接 return），避免与输入 / IME 打架。
+2. **chip 渲染**：仿 `createReferenceChip`。image 类型 → `size-6` 的 `<img src={reference.previewUrl}>`；其它类型 → 截断文字。chip 为 `contentEditable="false"` 的 `<span>`，用 `dataset.refLabel` 存 label 以便序列化。
+3. **value ← DOM（syncFromEditor）**：仿 `serializeNodes`，但 chip 序列化为 `dataset.refLabel`（label 文本）而非 node 标记；文本节点原样拼接，`<br>` → `\n`。
+4. **@ 菜单**：复用 `textBeforeCaret` + `/@([^\s@]*)$/` 检测；菜单定位改用 `getSelection().getRangeAt(0).getBoundingClientRect()`（比 textarea 的镜像 div 更简单、天然贴着光标）。菜单 UI 沿用现有 `MentionMenu` 的视觉（缩略图 + label + 副标题）。
+5. **原子删除**：直接复用 composer 的 `deleteAdjacentReference` / `adjacentReferenceNode` / `findReferenceSibling`——contentEditable + `contentEditable="false"` chip 天然整体删除。可把这几个通用 DOM 助手连同 `textBeforeCaret` / `placeCaretAtEnd` / `closestEditor` 复制进新组件（保持 composer 不动，规避回归风险）。
+6. **回车发送 + IME**：复用 `isPlainEnterKey` / `isImeComposing`（`@/lib/keyboard-event`）与 `onCompositionStart/End`，发送时调用 `onSubmit`。
+7. **占位符 & 样式**：空值时显示 placeholder（absolute 占位层）；容器套用面板传入的 `className/style`（`min-h-40`、透明底、无边框，与当前一致）。
+
+### 替换点
+
+`canvas-node-prompt-panel.tsx` 里把 `<CanvasResourceMentionTextarea .../>` 换成 `<CanvasPromptChipInput .../>`（同样的 value/references/onChange/onSubmit/className/style/placeholder）。其余（模型选择、设置、生成按钮）不动。
+
+### 不改动
+
+- `CanvasResourceMentionTextarea`（textarea 版）保留，节点内文本编辑继续用它。
+- 生成链路、`image-reference-prompt.ts` 前缀逻辑不变（value 仍是 label 文本）。
+
+## 影响文件
+
+- 新增：`web/src/components/canvas/canvas-prompt-chip-input.tsx`
+- 修改：`web/src/components/canvas/canvas-node-prompt-panel.tsx`（仅替换输入框组件 + 相应 import）
+
+## 验证
+
+1. `npx tsc --noEmit` 通过。
+2. dev server 刷新后：
+   - 连一张图片到图片 / 视频节点 → 面板输入框输入 `@` → 菜单贴着光标弹出 → 选中 → **输入框内显示该图的真实缩略图 chip**（不再是「图片1」文字）。
+   - 光标在 chip 后按一次 Backspace → 整个 chip 一次删除。
+   - 普通文字 + chip 混排，回车触发生成；确认发给生成的 prompt 里引用仍是「图片1」文本（生成结果正常引用到图）。
+   - 中文输入法输入不吞字、不误触发发送。
+   - 回归：双击文本节点进入内文本编辑仍正常（未受影响）。
