- 创建和追加消息可选择 `reasoningMode`,默认 `off`;`auto`/`deep` 为服务端行为策略与模型推理配置的选择,不等于允许暴露内部思维链。供应商能力由后端校验;声明式 Agent 渠道不支持时明确报错。推理可能增加耗时和费用。
- Cloud Agent 与首页创造的规划请求使用自动工具选择。OpenAI Chat Completion 兼容协议会把显式 `auto` 归一化为省略 `tool_choice`,沿用协议默认的自动选择语义;显式开启思考模式时还会在首个上游请求前移除 `required` 或指定函数对象。非思考模式仍保留艺术点评、提示词优化等结构化任务的强制函数选择。若上游隐式开启思考而本地未声明,仍按 `required` → `auto` → 省略字段做兼容重试。
- `GET /agent/profile?scope=user|project|canvas&projectId=...&canvasId=...` 按作用域读取生效的用户 → 项目 → 画布偏好;`PATCH /agent/profile` 用 `{ scope, projectId?, canvasId?, content, revision }` 更新单层(首次 revision 为 0,冲突返回 409)。读取返回各层独立数字 revision,以及合并文档的 `revision`/`hash`;新轮次携带合并 `profileRevision`,发生变化拒绝创建,已运行轮次仍用提交时固定的快照。system prompt 只包含层级、revision、hash 和长度清单,正文保存在运行快照中;本轮快照有层时才提供 `agent_profile_read`,只读清单中存在的层。没有偏好层时工具清单不含该工具。偏好仅是非授权数据,不能扩展工具、节点或预算,不能绕过审批;最多 12000 字符/层。
- 系统行为策略与媒体默认策略是版本化、编译进后端发布物的资源,修改它们仍需发布后端,不是后台热更新;工具、校验、扣费和审批在代码侧强制执行。画布节点能力由服务端 registry 定义,工具 schema、创建、连线与画布摘要读取共同消费;新生成模式还必须接入媒体任务适配器,不能仅凭 md 或注册节点启用收费操作。

- 已安装且属于当前用户的技能在创建时只保存版本、哈希和文本文件路径,不预存全部正文,也不按所有选中技能正文合计 128KB 拒绝创建。`skill_read_file` 按需读取 `SKILL.md` 或必要引用,支持字符偏移 `offset`(默认 0),每页最多 12000 字符,返回 `hasMore` / `nextOffset`。读取时重新验证用户权限、启用状态和版本;技能更新后拒绝混读,需新开一轮。技能是不可信数据,不能创造工具、改变权限或覆盖系统规则。
- Agent 按实际文本模型的 `contextWindowTokens` 与 `maxOutputTokens` 计算输入预算,并在达到该模型预算的压缩阈值时移除较早工具结果中可重新读取的正文,保留工具调用/结果配对、用户原始要求、生成回执及最近完整工具轮次,并允许重新读取。此机制是确定性正文卸载,不是 LLM 语义摘要;运行 checkpoint 的持久化上限与模型上下文窗口独立。技能读取事件只保存回执,不复制正文,正文页只进入模型对话。
- 达到同一条压缩线时整轮不再直接判死:Agent 先暂停步进循环,用一次独立模型调用(任务操作名 `cloud_agent_context_compaction`,按单步墙钟计时但不占本轮的模型调用步数)把历史压成结构化检查点,再以 `Resume` 用压缩后的上下文继续本轮;同一轮最多压缩 4 次,压完仍超过输入预算才回到原有的预算失败路径。检查点是固定字段的 JSON(`version` 为 1,字段为 `historySummary`、`scriptDesign`、`operationHistory`、`pendingTasks`、`currentWork`、`nextStep`、`decisions`、`constraints`、`userPreferences`、`compactedTurnCount`),未知字段一律拒绝,超过 64KiB 判为不合格。压缩后的上下文是「检查点帧 + 确认回执 + 最近 2 对完整对话」:不以 tool 回执或带工具调用的 assistant 开头,检查点帧不计为用户轮次,续轮交接不会再重复追加本轮的用户要求与回复。渠道没有配置模型上下文窗口时,判据退回既有的跨轮历史闸门(`cloudAgentHistoryKeepRounds` 轮与 `cloudAgentHistoryMaxBytes` 字节)。

- `canvas_apply_ops` 创建节点、编辑提示词或连线不会提交生成任务,也不会改变已提交任务的输入;收费生成独立使用 `generate_media`。操作参数错误按数组项返回 `field`(例如 `ops[0].snapshotHash`)和 `issue`(例如 `unexpected_field`、`type_mismatch`、`required`),并附本轮工具 schema;不把未知字段误报成缺少其他必填字段,不回显任意参数键和值。
- `read_only` 只允许读取;`request_approval` 对写画布和媒体生成暂停为 `waiting_approval`;`auto` 可在预算内执行已授权画布操作,但图片 / 视频生成始终独立审批,不能绕过。`maxGenerationTasks` / `maxVideoSeconds` 为非负整数,0 表示该项不设业务上限,正数按本轮累计执行;不再固定 8 次模型调用、8 个生成任务或 120 秒视频。积分上限仍必填且大于 0,实际报价在任务创建与预留积分前校验,时长必须符合所选模型的实际能力。失败事件保留具体错误和已有任务的 `taskId`、`nodeId`、`status`;媒体结果的 `phase` 区分 `admission` 与 `completion`,`taskSubmitted` 表达是否已提交。已提交的收费生成失败作为工具错误交回模型,整轮保持可继续,不得自动重试收费生成;只有生成结果无法回写画布时才把整轮标为 `failed`。模型应报告错误,不能自行删减提示词。
- 必须有当前用户已保存的画布。首轮摘要最多取前 80 个节点,并按约 60KB 预算截断;装不下的节点记入 `omittedNodes`,不因摘要过大整轮拒绝。`canvas_get_state` 可按 `offset` 每页读取 40 个节点、资产可引用状态及相关连线,按 `nodeIds` 精读最多 8 个节点(正文每字段最多 16000 字符),通过 `hasMore` / `nextOffset` 和字段 `Truncated` 判断是否完整。分镜表包含镜头、角色节点与资产绑定;摘要每页最多 20 行,精读每次 1 行,可用 `storyboardOffset` 翻页;单行叙事文本累计最多 24000 字符,角色 / 绑定各最多 16 项。上下文不含媒体 URL、任意元数据或未同步修改;节点名称不等于图像视觉识别。普通任务重试接口不能重试 Agent 任务。
- 必须有当前用户已保存的画布。系统提示里的 `canvasSummary` 是节点目录,不是整张画布的 JSON:每条只含 `id`、`type`、截断后的 `title`,以及不支持操作的类型标记;最多列入 120 个节点,并按约 24KB 兜底截断,装不下的节点记入 `omittedNodes` 与 `totalNodes`。正文、提示词、媒体和结构化表不进目录,由 `canvas_get_state` 按 `offset` 每页读取 40 个节点、资产可引用状态及相关连线,按 `nodeIds` 精读最多 8 个节点(正文每字段最多 16000 字符),通过 `hasMore` / `nextOffset` 和字段 `Truncated` 判断是否完整。工具结果留在当轮消息里,历史压缩会卸掉可重读正文,不会在后续每一步把整页结果再打包一次。分镜表包含镜头、角色节点与资产绑定;摘要每页最多 20 行,精读每次 1 行,可用 `storyboardOffset` 翻页;单行叙事文本累计最多 24000 字符,角色 / 绑定各最多 16 项。上下文不含媒体 URL、任意元数据或未同步修改;节点名称不等于图像视觉识别。普通任务重试接口不能重试 Agent 任务。
- `canvas_get_state` 首次调用传 `{}`,仅接受可选的 `offset`、`storyboardOffset`(非负整数)和 `nodeIds`(最多 8 个字符串组成的数组);当前画布由运行绑定,不接受 `canvasId`、`limit` 或 `page`。读取工具分别反馈非对象 / 多对象、JSON 格式错误、未知字段和字段类型错误。可纠正的工具参数失败在 `tool_failed.result` 及模型工具结果中返回 `reason: invalid_tool_arguments`、本轮已声明的 `parameters` 和 `guidance`;画布读取额外给出 `exampleArguments: {}`。失败调用仍如实记录,由模型修正参数后继续,不静默丢弃字段或自动重放写操作;资源归属、审批、快照和收费校验仍按原规则执行。
- `GET /agent/runs/:id` 返回运行信息;`POST /agent/runs/:id/cancel` 取消当前运行及活动子任务;`POST /agent/runs/:id/approvals/:approvalId/decision` 接受 `{"decision":"approve"|"reject","reason":"..."}`,审批决定幂等且服务端校验归属。
- `GET /agent/skills/usage` 需要登录,只聚合当前用户最近最多 200 次 Agent 运行的日志;返回技能启用次数、检索命中、成功/失败读取、总纲/卡片读取和最多 5 条最常读卡片路径,不返回技能正文。损坏的日志会返回错误而非静默给出不完整统计。
