+# Infinite Canvas Agent
+
+你正在帮助用户操作 Infinite Canvas 网站。
+
+- 用户要求操作画布时，默认目标就是网页当前已经打开的画布。需要了解内容时先使用 `canvas_get_state`；读取成功后直接在该画布执行任务，不要调用 `canvas_list_projects`，也不要用 `site_navigate` 重复进入画布。
+- 只有用户明确要求查看、选择或切换其他画布，或者 `canvas_get_state` 明确提示当前没有已连接画布时，才使用 `canvas_list_projects` 和 `site_navigate`。`site_navigate` 可跳转 `/`、`/canvas`、`/canvas/:id`、`/image`、`/video`、`/prompts`、`/assets`、`/config`。
+- 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`。
+- 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。
+- 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。
+- 用户要求生成图片、视频、音频或文本时，默认调用对应的 `canvas_generate_image`、`canvas_generate_video`、`canvas_generate_audio`、`canvas_generate_text`，通过当前画布的生成节点完成任务。
+- 只有用户明确要求使用“Codex 内置生图”“ImageGen 技能”或意思明确相同的能力时，才使用 Codex 自带的 `imagegen`；不要因为用户只说“生成图片”就自行改用内置生图。内置生图完成后，其结果会由 Canvas Agent 自动展示到对话并插入当前画布，无需再创建空节点或重复生成。
+- 只有用户明确说要在生图/视频工作台生成时，才使用 `workbench_image_*`、`workbench_video_*`。生成任务提交后应说明已经在画布或工作台开始生成，不要在实际没有结果时声称“已生成”。
+- 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。

 执行后，前端会保存最近一次操作前的画布快照，用于撤销上一轮 Agent 工具操作。

 # 待测试

+- Agent 模型设置：连接 Canvas Agent 后，输入框左下方应显示当前 Codex 模型与推理强度；模型列表应来自当前账号实际可用模型且不显示内部审查模型或重复项，切换模型后强度选项随模型能力更新且无空白选项，刷新页面后保留选择，发送任务时实际使用所选模型和强度；本地控制台与右侧「日志」应记录本轮使用的模型和推理强度。
+- Agent 新对话响应：一轮对话完成后点击「新对话」，聊天内容应立即清空并进入空白对话，不出现等待或新建按钮卡顿；此时不应生成空历史记录，第一次发送消息时才创建线程；多个标签页应同步进入空白对话，点击后立即发送也不得误发到上一条会话。
+- Agent 读取画布卡片：读取当前画布完成后，卡片应按非零类型显示文本、图片、配置、视频、音频、分组、其他节点及连线数量，例如「3 个文本、5 张图片、2 个配置、4 条连线」；空画布应显示「当前画布为空」，执行失败时仍应显示错误信息，刷新恢复历史后统计保持一致。
+- Agent 首次发送响应：在空白新对话中输入内容并按回车后，输入框应立即清空、用户消息应立即出现在对话中，再显示「正在思考」；线程创建或发送失败时，原输入和附件应恢复；任务运行期间输入的新草稿不应在请求成功后被清空。
+- 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。
+- 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。
+- Canvas Agent Codex 升级：启动 Canvas Agent 后应输出 Canvas Agent、内置 Codex 和本机 Codex 版本，实际运行的内置 Codex 应为 0.146.0；内置与本机版本不一致、未安装本机 Codex，或 npm 存在更新版本时应显示对应升级提醒，npm 检查失败不应阻止服务启动；Agent 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，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。
+- Canvas Agent Debug：普通启动应通过公共 logger 输出 Info、Warn 和 Error 日志；使用 `npx -y @basketikun/canvas-agent --debug` 启动后还应输出 Debug 日志并显示日志文件路径，终端统一采用“`YYYY-MM-DD HH:mm:ss` 级别 消息 详情”的纯文本单行格式，`~/.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；日志中不应出现连接 token 或图片 Data URL 原文。
+- Canvas Agent Codex 日志：Codex app-server 输出带颜色或样式控制符及 UTC 时间的 stderr 时，本地日志和网页诊断日志应只显示一份 `YYYY-MM-DD HH:mm:ss` 本地时间和干净文本，不应出现重复 ISO 时间或 `[2m`、`[31m` 等 ANSI 转义内容。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
+- 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。
 - 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。
+- 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。
 - 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。
 - 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。

 - 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。
 - 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。
 - 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。
- 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。
