AGENTS.md

@@ -96,7 +96,7 @@ The frontend (`frontend-web/`) is a React 19 + Vite SPA:
 - **智能体使用引导 (Agent onboarding tour, 三段式)**: 智能体「浏览管理 → 创建与配置 → 发起问答」全流程分步引导，组件 `components/workspace/agents/agent-guide.tsx`（同一 TDesign `Guide` 封装模式，与简洁模式引导共享记忆语义：**仅显式点「完成/跳过」才写 localStorage** `deerflow.agent-guide.<stage>.finished`，中途刷新/离开不记忆）。**自动演示仅 create / chat 两段**（进智能体列表页不弹引导，点「创建智能体」进入新建页时才自动演示；list 段的 `AgentGuide` 传 `autoStart={false}`，只能由头部「使用引导」按钮手动触发）。三段各自挂载、各自记忆：① `list`（`agent-gallery.tsx`，/page/workspace/agents）——分区 Tabs、搜索排序、智能体卡片操作、右上「创建智能体」按钮；**完成/跳过就地结束（不跳转创建页，与 create 段无联动）**，最后一步仅提示进入创建页后会有配置引导；② `create`（`NewAgentPage.tsx`，/page/workspace/agents/new）——左侧对话式创建输入区、基本信息、运行模型+入库模板名、知识空间、SOUL.md、技能穿梭框、保存按钮（9 步）；③ `chat`（`AgentChatPage.tsx`，agents/:id/chats）——左栏切换与历史、常用问题 chips、输入框（落地态/会话态两个挂点同一 `chat-input` 标记）、右侧详情面板；`eligible` 限定普通智能体对话页（`showAgentList && !isEmbedded && !taskCtxOn`，即排除通用问答原地嵌入与任务深链工作区），三段共用 `isAgentGuideEnvironment()` 排除 embed/hideChrome/无界环境。高亮锚点 `data-agent-guide`：列表页 `tabs`/`search`/`agent-card`（卡片+列表两种布局的根元素）/`new-agent-btn`，创建页 `create-chat-input`/`create-basic`/`create-model`/`create-knowledge`/`create-soul`/`create-skills`/`create-save-btn`，对话页 `chat-sidebar`/`chat-questions`/`chat-input`/`chat-detail`；同样**启动时按目标存在性过滤步骤**（新用户无卡片/无预设问题时自动剔除）。手动重放：三个页面头部各有「使用引导」按钮（列表页创建按钮左侧、创建页 header 右侧、对话页 header），广播 `agent-guide:start:<stage>` 窗口事件强制重放（忽略已看过记忆）。
 - **敏感词管理 (Sensitive Word Management)**: configures the **展示层脱敏映射** (原始词 → 替换词). **Gated on the username `lqq`** (not the admin role) — `getAccountDisplayName().toLowerCase() === "lqq"` (username = email `@` prefix, else `user_id`, same as the profile page); the dropdown entry, the route guard, and the page-level guard all use this check. `src/lib/desensitize.ts` ships a frozen seed map `SEED_DESENSITIZE_MAP` (the deployment seed) plus a live mutable `DESENSITIZE_MAP` (initialized from the seed so `desensitize()` works before any fetch). `DesensitizeWordsLoader` (mounted in `App.tsx` `AppProviders`) fetches `/api/sensitive-words` on startup and, if non-empty, calls `replaceDesensitizeMap(...)` to make the backend config the source of truth (empty/failed → keep seed). Page `SensitiveWordsPage.tsx` (route `/page/strategy/admin/sensitive-words`, opened from the 「敏感词管理」 item in the **bottom-left settings dropdown** of `components/page-sidebar.tsx`, present in **both** full + collapsed sidebar modes) lists/adds/edits/启停/deletes words and saves the **whole set atomically** (replace-all); a 「导入种子词」 button merges any missing `SEED_DESENSITIZE_MAP` entries into the editor. Client + hooks in `strategy-components/api/sensitive-words.ts` (`wordsToMap` folds enabled rows into the runtime map). Backend: `/api/sensitive-words` (global/shared; open read, write allowed for admin **or** the `lqq` account), mirroring 菜单管理's store shape. **侧边栏 + 导航栏 menu labels are desensitized** at the data source: `useSidebarMenuItems`/`useActiveThirdLevel` (`core/page-layout/use-sidebar-menu.ts`) map every node's `label` through a desensitizer built **directly from the `/api/sensitive-words` query** (`makeDesensitizer(wordsToMap(words))`, falling back to the global seed `desensitize` while empty) — this sidesteps the `replaceDesensitizeMap` effect-timing race. Only `label` is rewritten; `path`/`id`/`icon` are untouched so routing/highlight are unaffected. All nav surfaces (`page-sidebar.tsx`, `page-sidebar-dark.tsx`, `page-sidebar-v1.tsx`, `strategy-components/Header.tsx`, `PageRoutes.tsx`) consume this hook and are covered; `MenuManagementPage` uses the raw tree so admins still edit real labels.
 - **技能地址管理 (Skill Address Management, admin-only)**: 扫描运行中的技能（`skills/{public,custom}` 下所有 `.md`/`.py`）里的 **http(s) URL 与 IP/IP:端口**，按唯一地址聚合全部出现位置（跨 .md/.py），支持**批量替换**（如把 UAT 地址一次性改成生产）。主体抽成可复用组件 `SkillAddressesPanel`（`pages/SkillAddressesPage.tsx` 导出，默认导出 `SkillAddressesPage` 仍保留旧路由 `/page/strategy/admin/skill-addresses` 作直链回退），**作为「技能地址管理」标签页嵌入管理员「技能管理」页 `pages/AdminSkillsPage.tsx`**（该页加 Tabs：「技能列表」+「技能地址管理」；入口在「设置和更多」下拉的「技能管理」`workspace-nav-menu.tsx` → `/page/workspace/admin/skills`，不再单列于 `components/page-sidebar.tsx` 左下角设置下拉）：打开自动扫描并带**进度条**（扫描逐技能 / 应用逐文件 X/N，应对 150+ 技能），URL/IP 类型过滤 + 搜索 + 「片段批量套用」（如所有 `uat.4.cn` → `prod.4.cn`）、每地址「替换为」输入框（可展开看 `file:line` 片段）、内联**预览**、**应用**、**多关键词检索**（空格分隔全部命中），以及**修改记录**面板——每次应用生成一条记录（显示时间/改了哪些地址 from→to/文件数/处数），可**针对单次记录回退**（二次确认）。client + NDJSON 流式解析在 `strategy-components/api/skill-addresses.ts`。后端 `/api/skill-addresses`（**仅管理员**）：所有文件 IO 走 `asyncio.to_thread` 不阻塞事件循环；`GET /scan`(+`/scan/stream`)、`POST /preview`、`POST /apply`(+`/apply/stream`)、`GET /backups`、`POST /rollback/{id}`；**子串安全替换**（基于 token span，不会误伤子串）、`expected_total` 乐观锁（409）、写前自动磁盘备份到 `{skills_root}/.address-edits/`（同时写一份 `{id}.manifest.json` 记录本次替换明细，供修改记录展示）、应用后刷新技能系统提示缓存。纯引擎 `deerflow/skills/address_scan.py`，router `app/gateway/routers/skill_addresses.py`，tests `tests/test_skill_addresses.py`。范围仅运行中技能，不动 `deploy/minimal/skills/`。

Each button = `{business, label, linkType, target, appendTaskId, idParam, idKind, enabled, sortOrder}`; `linkType` is `url` (外链 `window.open`, optional append of `?{idParam}={id}` — **`idParam` is the editable query-param name**, e.g. `id`/`task_id`), `business` (内部切换到另一业务, reuses `resolveTaskDeeplinkTarget`, always task id), or `purpose` (弹出当前任务的「任务目的」表格 via the shared `TaskPurposeDialog`, no target — configurable for any page incl. xdfx). **`host`（宿主路由）** asks the embedding parent to navigate: `runTaskButton` sends `window.parent.postMessage({ type:'HOST_NAVIGATE', path, queryParams:{ [idParam]: Number(taskId) } }, hostOrigin)` — `target` is the host route, `appendTaskId`/`idParam` become numeric `queryParams` (task id, or action id when `idKind:"action"` — same selector as url buttons, xdfx only), origin from `runtime-config.js` `VITE_HOST_NAVIGATE_ORIGIN` (else ancestorOrigins/referrer; never `*`). **`idKind` (`task`/`action`) only matters for xdfx**: its deep-link `?taskId=` is an 行动id and the 任务id is resolved at login (`fetchTaskIdFromAction`) — `TaskContext` now also stashes the raw `actionId`, so a url **or host** button can append either (default `task`).
