+- 切换网站页面使用 `site_navigate`，可跳转 `/`、`/canvas`、`/canvas/:id`、`/image`、`/video`、`/prompts`、`/assets`、`/config`。
+- 修改画布前优先使用 `canvas_get_state`，再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`。
+- 用户要求把上传附件放入画布或作为生成参考图时，必须先用 `canvas_create_attachment_nodes` 创建真实图片节点，再把节点 ID 传给生成流程，不要创建空图片占位节点。
+- 当前不在画布页时，先用 `site_navigate` 打开画布。查看已有画布时，先用 `canvas_list_projects` 获取画布清单和 ID。
+- 生图与视频工作台分别使用 `workbench_image_*`、`workbench_video_*` 工具；提示词和素材分别使用 `prompts_search`、`assets_*` 工具。
+- 需要生成内容时直接调用对应生成工具，不要绑定特定业务场景，不要模拟鼠标点击，不要要求用户手动复制 JSON。

 # 待测试
 
-- 左侧画布面板「资产」Tab：搜索框旁「添加」按钮可上传图片/视频文件（支持多选）加入资产库；每张资产卡片悬停显示移除按钮，二次确认后删除；点击卡片仍插入到画布；需验证添加图片/视频、非图片视频文件的提示、移除确认与插入行为。
+- Canvas Agent Debug：使用 `npx -y @basketikun/canvas-agent --debug` 启动后，终端应以 `[DEBUG][HH:mm:ss]` 等传统格式输出带级别颜色的详细日志并显示日志文件路径，`~/.infinite-canvas/logs/` 下应按启动日期生成不含颜色代码的 `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。
-- 左侧画布面板：支持拖拽右边缘调整宽度（记忆到本地）、通过顶栏菜单左侧的开关按钮展开/收起，展开收起有动画；需验证宽度拖拽、动画、刷新后保持展开/收起状态与宽度。
+- 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 GPT 图标和 `working...`，任务运行期间不应闪退；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。
-- 左侧画布面板：「画布/资产」切换改为带滑动下划线的动画；点击「画布元素」列表项跳转到对应节点时带缓动动画（视图平滑移动缩放而非瞬移）；文本/配置/视频/音频等非图片元素的图标去掉灰色底色；需验证视觉与交互。
+- 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。
-- 左侧画布面板：画布元素列表点击「选择」进入多选模式，可勾选/全选节点后「导出选中」为压缩包；压缩包为扁平结构——图片/视频/音频直接是对应文件（按节点名称命名、重名自动加序号），文本节点为 `.txt`，其余无法识别的节点各自导出为同名 `.json`；需验证多选、全选、导出内容与命名正确。
+- 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。
-- 顶栏菜单：新增「导出当前画布」，导出当前画布为压缩包（与项目列表页单个导出格式一致）；需验证导出文件名与内容。
+- 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。
-- 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。
+- 生图工作台参考图：将一张或多张图片拖入参考图区域后应直接上传并显示缩略图；拖入非图片文件应忽略，拖动过程中区域应显示高亮提示，放下文件不应导致浏览器打开或替换当前页面。
-- 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)。
+- 视频创作台参考资产：将图片、MP4/MOV 视频或 MP3/WAV 音频拖入任一参考资产区域后，应按文件类型自动上传到对应列表；当前拖入区域应显示高亮提示，原有数量、大小、时长和格式限制应继续生效。
-- 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。
+- 画布组装提示词：输入或连接超长提示词后，浮层正文高度不应继续撑大，内容应可在正文区域内滚动查看和编辑，标题及关闭按钮保持可见。
-- 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。
+- 画布节点提示词：图片等节点下方的提示词超过输入区域高度后，鼠标悬停在输入区域内滚动应查看提示词内容，不应缩放画布。
-- 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。
+- 画布节点提示词回显：单图或多图生成完成后，切换选择生成结果的根节点及任一子节点，下方输入区域都应继续显示生成时的提示词；切换到其他节点再选回来后也不应清空。
-- 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。
+- 画布生成配置：连接文本节点后连续点击生成（包含失败重试），组装提示词不应重复追加上游文本；在生图、文本、视频、音频之间切换时，实际请求应始终使用当前面板展示的对应类型模型。
-- 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。
+- 画布左侧元素列表：点击元素整行应平滑定位并选中对应节点；有内容的图片元素应显示预览按钮，点击后打开大图弹窗且不触发画布定位。
-- 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。
+- 配置与用户偏好：导出 JSON 后应包含渠道、默认模型、生成偏好、提示词来源和 WebDAV 配置；在修改当前配置后重新导入该文件，应恢复导出时的设置，错误 JSON 文件应提示格式不正确。配置文件包含 API Key 和 WebDAV 凭据，不应公开分享。
-- 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。
+- 模型渠道协议：渠道编辑可选择「火山方舟」并自动填入方舟接口地址；任意名称的生图模型应按方舟 JSON 格式提交参考图，任意名称的视频模型应按方舟任务格式提交和查询，不再依赖模型名包含 `doubao`、`seedream` 或 `seedance`；1080p 不应再因模型名包含 `fast` 被禁用，参考视频应允许最大 200MB、总像素 409600-8295044，并继续校验官方宽高、比例和时长限制。
-- 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。
+- 图片编辑弹窗：遮罩、切图和裁剪连续滚轮缩放时，图片与遮罩应保持同步且不再闪烁、短暂消失或跳动；遮罩画笔圆心应始终固定在鼠标位置，仅直径随缩放变化，缩放后仍可准确涂抹、拖动切分线和调整裁剪框。
-- 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。
+- 提示词中心布局：页面标题及提示词总数应居中；连续输入搜索文字时应在停止输入约 300ms 后再查询；桌面端分类与标签应在左侧独立滚动，右侧搜索框下直接展示提示词卡片；标签数量较多时不能继续向下挤压提示词，窄屏下应恢复上下排列且内容不溢出；不再显示「我的提示词」Tab，收藏提示词应直接加入我的资产。
-- 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。
+- 提示词详情弹窗：封面和参考图应固定显示在上方，复制及加入资产操作栏固定在底部，只有中间的标签、描述及提示词内容区域可以滚动；弹窗宽高应受视口限制且不超出屏幕。
-- 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。
+- 提示词来源：6 个内置来源应从 Image Prompts 统一仓库读取，更新后数量依次为 323、494、53、76、126、129；提示词仍按 6 个来源分组并可独立启用，来源内可继续按 `tags` 筛选。添加标准 JSON URL 后应能查看内容，填写非数组 JSON 或不可访问地址时应显示失败，并继续保留该来源上一次成功缓存的内容。
-- 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。
+- 提示词来源界面：来源应以卡片列表展示，启用开关位于左侧，数量、同步状态和上次成功时间作为次级信息显示，查看、拉取及自定义来源编辑/删除操作使用带文字按钮；底部定时拉取区域应保持独立边框布局。
-- 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。
+- 画布提示词库：不应再显示「我的提示词」分组；不展开任何公共来源直接搜索其中的提示词，匹配项应自动显示；点击「插入画布」后应创建正文正确且标题保持为提示词标题的文本节点。
-- 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。
+- 全站 Agent：新增 `generation_get_status` 工具，画布生成节点可按 `nodeIds` 查询，生图和视频工作台提交后会返回 `taskId` 并可查询排队、运行、成功或失败状态；需验证查询只由当前活动标签页返回。
-- 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。
+- 本地 Agent 多标签页隔离：同时打开两个不同画布并连接同一个 Agent，分别聚焦标签页后通过 MCP 读取和修改画布，操作应只落在当前聚焦页面；网页面板发起的整个 Codex turn 应固定操作发起页面，即使中途聚焦另一标签页也不能切换目标；关闭当前页面后应回退到最近聚焦且仍连接的页面，其他页面回传同一请求结果应被拒绝。
-- 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。
+- 本地 Agent 多标签页会话同步：所有标签页共享同一个站点级 Codex 活跃线程；任一页面发送消息、新建、恢复或删除会话后，其他页面应同步活跃线程和聊天记录；Agent 输出仅显示在事件所属线程，运行中不能新建、恢复、删除或再次发送任务。
-- 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。
+- 本地 Agent 运行状态同步：在一个标签页运行较长 Codex 任务，等待某张工具卡显示「工具完成」后再打开或刷新第二个标签页；第二个标签页应立即显示 Codex 正在运行并禁用发送，整轮结束后两个标签页同时恢复；工具卡只显示「工具完成」，整轮结束由「本轮完成」表示。
-- 画布图片切图：行数 / 列数会生成可直接拖拽的等分切图线，并支持新增横向 / 纵向线、删除单条线、重置切图线和切片数量预览。
+- 本地 Agent 图片附件落画布：在右侧 Agent 上传参考图并要求基于商品信息创建生图流程，附件应创建为保持原比例的真实图片节点，分析提示词应创建为文本节点，二者都应连接到生成配置节点；刷新页面后参考图仍可显示并参与生成。任务中途切换到其他标签页时，附件只能写入发起任务的标签页；若发起标签页关闭，附件读取应失败且不能落入其他画布。
-- Codex App 插件：精简插件 README 安装步骤，更新插件网站和作者信息，并将 `open-canvas` 调整为默认打开在线画布、仅按需启动本地前端；需重新安装后确认详情页和两种打开流程正确。
+- Agent 对话滚动：从历史或日志切回对话、恢复其他会话时应自动定位到最新消息；手动向上浏览后应显示向下箭头且新消息不强制打断阅读，点击箭头后平滑回到底部并继续跟随新消息。
-- 本地 Codex 连接画布文档：新增 Canvas Agent、MCP、SSE 与浏览器画布交互原理说明，需确认文档导航和描述是否清晰。
+- Agent 消息区分：用户消息应在右侧以主题浅底气泡显示，AI 回复应在左侧保留 Agent 图标并使用开放式 Markdown 排版；长文本、多张附件、错误消息及浅色/深色主题下均应清晰且不溢出。
-- 顶部导航：缩小桌面顶部导航栏高度，导航项下划线和内容垂直对齐需确认。
-- 配置与用户偏好：新增独立顶部导航页面，并在页面和弹窗中复用同一套配置面板；新增 Codex Tab，展示插件安装和本地 Agent 启动步骤，可配置本地 Agent 地址、Connect token 和工具执行确认开关。
-- Codex 全局连接：配置页可直接连接本地 Canvas Agent，连接状态同步到画布和顶部 OpenAI 状态图标，刷新后会按本地保存的地址和 token 自动尝试重连；需验证已连接、连接中、连接失败、断开和刷新自动重连状态。
-- 画布 Agent：Codex 旧 thread 在重启后不可用时会自动新建会话并重试，需验证进入画布直接发送消息不会再出现 `thread not loaded` 或 `no rollout found`。
-- 画布 Agent：切换不同画布时会清空并重新加载当前 canvasId 对应的 Codex 会话，需验证不会继续显示上一个画布的对话。
-- 画布 Agent：右侧 Agent 面板移除网站 / 本机模式切换，固定使用本机 Agent。
-- 配置与用户偏好：每个模型渠道新增 OpenAI / Gemini 调用格式选择，默认 OpenAI，切换默认格式时同步更新默认 Base URL；渠道 Tab 增加紧凑醒目的提醒，说明模型是否可选需要到“模型”Tab 选择。
-- Gemini 调用格式：支持拉取 Gemini 模型列表，并用于文本问答、在线 Agent 工具调用、基础生图和图生图请求。
-- Gemini 生图：生图工作台和画布生图会把尺寸配置转换为 Gemini `responseFormat.image.aspectRatio` 传入，需验证 1:1、9:16、16:9 及自定义像素尺寸的输出比例。
-- 音频和视频生成：选择 Gemini 调用格式时先给出不支持提示，仍需使用 OpenAI 兼容渠道。
-- WebDAV 同步：移除 Next.js 转发代理和连接方式选择，改为浏览器前端直接连接 WebDAV 服务。
-- 提示词库：移除 Next.js route 抓取和服务端内存缓存，改为浏览器前端直连 GitHub 原始文件并缓存到 IndexedDB。
-- 提示词库：移除已 404 的 `EvoLinkAI/awesome-gpt-image-2-API-and-Prompts` 来源。
-- 前端构建：移除 Next.js，改为 Vite + React Router，并将前端目录调整为 `pages` / `components` / `stores` / `lib` / `layouts` / `styles`，需验证首页、图片/视频工作台、素材、提示词库和画布路由跳转。
-- 前端构建：修复 TypeScript 严格检查下的构建报错。
-- Vercel 部署：新增 `web` 和 `docs` 两个子项目的 Vercel 配置，需分别验证静态前端和文档站部署。
-- Docker 部署：运行镜像从 Node serve 改为 nginx 静态托管，需验证前端路由刷新回退。
-- 环境变量：移除过期的后端 `.env.example` 示例文件。
-- 生图工作台：修复失败图片点击重试后只保存在页面状态、刷新或跳转后丢失的问题，重试成功结果会写入本地图片存储和生成记录。
-- 视频生成：任务查询接口直接返回 `url` / `result_url` / `video_url` 时会跳过 `/content` 下载，并优先保存到浏览器本地媒体存储。
-- 视频生成：任务创建或查询失败时会解析接口返回的 `msg` / `message` / 嵌套 JSON 错误，并在生成结果失败卡片里展示真实原因。
-- 画布生成配置：修复切换文本/视频/音频模式时模型选择仍显示为生图模型（gpt-image-2）的问题，切换模式后应自动匹配对应能力的默认模型。
