+**agentfx built-in analyst + report convert skills.** `agentfx-analyst` (「任务研判报告助手」) is seeded from `app/gateway/routers/_agentfx_seed_assets/` before `_sync_legacy_agents`. After mandatory `web_search`, the agent writes each tool JSON to `/mnt/user-data/workspace/hits/qN.json` and runs **one** command — `task-report-build` (group `all`) — to fill the 14-category `task-reports.json` for the dashboard slots; the four per-page skills `task-report-{enemy,our,env,judge}` remain for re-running a single dashboard page. All five are thin CLIs over the shared stdlib engine `skills/public/task-report-lib/convert_lib.py` (no SKILL.md on the lib, so it never enters the skill list). The model must not `write_file` that JSON. Because the sandbox maps `/mnt/user-data/...` onto a host dir, a virtual absolute hits path can be `isdir`-true yet list empty on a Windows host — `resolve_hit_files` therefore tries the path as given, then the cwd-mapped sandbox path (`discover_user_data_root` + `resolve_sandbox_path` — bash `cd`s into the thread `workspace`, so `/mnt/user-data/outputs/task-reports.json` must land in that thread's `outputs/`, never `F:\mnt\...` on a Windows host), then the virtual-prefix-stripped relative form, then the bare dir name, and picks the first candidate that actually contains `.json`; a miss returns a `warnings` entry listing every tried form so the agent never has to write a debug script. Assemble of the 14 categories is the same function (`assemble_records`); the model must not copy or merge files. If the model is interrupted after convert, `task-reports.json` is already in outputs and the frontend import card also scans `GET /api/threads/{id}/artifacts` so入库 still works without `present_files`. Import remains `task-report-import`. Existing agent/skill directories are never overwritten. Tests: `tests/test_task_report_convert.py`, `tests/test_agentfx_seed.py`.
 
 **Forced-research built-in agent.** `forced-research-responder` (「强制检索输出助手」) is seeded from `app/gateway/routers/_forced_research_seed_assets/` before `_sync_legacy_agents`. `ForcedResearchMiddleware` is mounted only for this stable id. On every visible user turn it requires a successful information-gathering tool result before the model may finish; `tool_choice=required` is backed by an `after_model -> model` retry for gateways that ignore tool choice, with an eight-attempt failure cap that permits only an honest failure response. Skill discovery, reading `SKILL.md`, and writing a helper script do not satisfy the gate; web/knowledge/MCP results, non-skill uploaded-file reads, or successful Python skill-script execution do. Tool filtering removes `present_files`, `skill_manage`, task/schedule/memory/clarification surfaces. The middleware permits `write_file`/`str_replace` only for `/mnt/user-data/workspace/*.py` and permits `bash` only for `.py` execution without redirection/document paths, so skills can run scripts but the agent cannot create Markdown/document artifacts or write `outputs`. Tests: `tests/test_forced_research_agent.py`.

 The separately deployed TaskCOP Vue app uses `POST /api/v1/auth/login/username` directly (its `username`, `userId`, or `yUserId` URL parameter identifies the user), so this compatibility flow does not depend on the retired Consumer login service. It calls the Gateway address configured as `b1ConsumerUrl` directly; it does not use a Vite `/api` reverse proxy. An empty TaskCOP store remains empty; task data is introduced through normal creation or the JSON import API. The Gateway CORS middleware always merges local Vite origins `http://localhost|127.0.0.1:{5173,5174,3000,8080}`, including when `GATEWAY_CORS_ORIGINS` is set for another frontend. This keeps a Vite server that falls back from 5173 to 5174 (or the reverse) working after a backend restart. For a deployment, set `GATEWAY_CORS_ORIGINS` to the exact additional frontend origins that are allowed to call the Gateway.

+description: 添加受众目标入库：校验受众JSON载荷，登录任务系统后按完整链路（查重→删除同名受众及其关系表→创建受众目标→创建账号关联）调用接口，并如实回报每个接口的入参与调用结果。
+allowed-tools:
+  - read_file
+  - bash
+---
+
+# 添加受众目标（完整链路入库）
+
+当且仅当需要把分析产出的受众目标（含关联账号）写入任务系统时使用本 Skill。脚本会自动完成：登录鉴权 → 查重 → 删除同名受众（连带删除 `task-action-pathway-account` 关系表与脆弱点关联）→ 创建受众目标 → 创建账号关联。
+
+## 前置条件
+
+先用 `write_file` 把载荷写到 `/mnt/user-data/outputs/add-audience-payload.json`，结构如下（`targetAudience` 也可写作 `groupName`）：
+
+```json
+{
+  "taskId": 101,
+  "actionId": 201,
+  "audienceList": [
+    {
+      "targetAudience": "18-30岁智能穿戴尝鲜用户",
+      "recReason": "对新形态设备接受度高……",
+      "userList": [
+        {
+          "id": "mock_fa_0001",
+          "name": "极客评测室GeekBench",
+          "platformType": 1,
+          "platform": "facebook",
+          "dataSource": "target",
+          "score": 0.93,
+          "metadata": { "...": "完整user对象会整体存入 frofileInfo" }
+        }
+      ]
+    }
+  ]
+}
+```
+
+- `taskId` / `actionId` 必须是整数，等于当前任务与行动 ID。
+- `userList` 每项是完整 user 对象：`id`、`name` 必填；`platformType` 写入 accountPlat；`accountSource` 优先取 `dataSource`，缺失时回退 `score`；整个对象 JSON 序列化后存入 `frofileInfo`。
+- `recReason` 中的 `<n>` 引用标记会被自动清洗，无需预处理。
+
+完整字段定义、账号对象字段表与生成规则，见：
+
+```text
+/mnt/skills/public/add-audience/docs/受众JSON生成规范.md
+```
+
+（custom 安装时把路径中的 `public` 换成 `custom`；需要生成载荷时，先读该规范再写 JSON。）
+
+## 接口地址与鉴权配置
+
+部署时编辑以下文件（安装到 custom 时把路径中的 `public` 换成 `custom`）：
+
+```text
+/mnt/skills/public/add-audience/config/audience_api.json
+```
+
+| 配置项 | 说明 |
+| --- | --- |
+| `base_url` | 任务系统地址（到端口，不带 `/api`），如 `http://192.168.1.11:3912` |
+| `username` / `password` | 登录账号（环境变量 `AUDIENCE_API_USERNAME` / `AUDIENCE_API_PASSWORD` 可覆盖） |
+| `request.verify_ssl` | **默认 false，已关闭 HTTPS 证书校验**，适配自签名证书内网环境；公网环境建议改回 true |
+| `request.timeout_seconds` | 每个请求的超时秒数，默认 30 |
+
+鉴权流程（脚本自动完成）：`POST {base_url}/api/auth/login`（body `{username, password}`）取 `access_token`，后续所有请求附加请求头 `Authorization: Bearer {access_token}`。
+
+## 执行方式
+
+```bash
+python /mnt/skills/public/add-audience/scripts/add_audiences.py \
+  --json /mnt/user-data/outputs/add-audience-payload.json
+```
+
+可加 `--dry-run` 只校验载荷并打印调用计划，不实际发送。环境变量覆盖地址：`AUDIENCE_API_BASE_URL`。
+
+## 结果处理（必须如实转述）
+
+脚本 stdout 是一段 JSON，其中：
+
+- `入参摘要`：本次传入的 taskId/actionId 与每个受众组（名称、清洗后理由、账号数）——**必须告知用户**。
+- `calls`：每个接口的 method、url、请求体（密码与 token 已脱敏）、HTTP 状态与响应——**必须汇总告知用户**，特别是删除了哪些同名旧受众及其关系表记录、新建的 designId。
+- `groups` / `summary` / `人读摘要`：分组结果与统计。
+
+规则：
+
+- `success: true`：按 `人读摘要` + `groups` 如实汇报新增/删除数量。
+- `success: false`：如实说明失败步骤与错误（如登录 401 → 提示检查 config 账号密码），**不要假装调用成功**，也不要静默吞掉失败。
+- 不要自己用 curl / requests 逐条调接口替代本 Skill；不要在未执行脚本的情况下宣称"已添加"。
+
+## 同名受众处理策略
+
+与前端行为一致：同名（`targetAudience` 相同）受众已存在时**先删后建**，删除链为：关系表 `task-action-pathway-account`（按 pathwayId 逐条）→ `task-action-design/deleteDesignVulns?designId=` → `task-action-design/{id}`。如用户只想要"跳过已存在"而非覆盖，需在执行前明确说明并由用户决策。

+## 二、字段定义
+
+### 顶层
+
+| 字段 | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `taskId` | integer | ✅ | 当前任务 ID。**必须取自用户上下文/前端传入，禁止编造**；未知时先向用户询问 |
+| `actionId` | integer | ✅ | 当前行动 ID。同上 |
+| `audienceList` | array | ✅ | 受众组数组，**至少 1 项**；按推荐优先级排序（S 级在前） |
+
+### audienceList 每项
+
+| 字段 | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `targetAudience` | string | ✅ | 受众群体名称。去掉首尾空格后非空；**同一载荷内不得重名**；简洁（建议 ≤ 20 字），如「中高端降噪耳机通勤党」。不要写 `groupName`，统一用本字段 |
+| `recReason` | string | 推荐 | 入选理由，一两句话。文本中的 `<数字>` 引用标记、顿号、「引用」、空括号会被脚本自动清洗，无需预处理；但也不要故意堆这些符号 |
+| `userList` | array | ✅ | 该群体关联的账号数组，**必须为数组**（允许空数组 `[]`，表示只建群体不挂账号） |
+
+### userList 每项（账号对象）
+
+| 字段 | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `id` | string\|number | ✅ | 账号唯一标识 → 写入接口字段 `accountId` |
+| `name` | string | ✅ | 账号名 → 写入 `accountName` |
+| `platformType` | integer | 建议 | 平台编码 → 写入 `accountPlat`（facebook=1、x=2、instagram=3、threads=5、youtube=6、tiktok=7） |
+| `platform` | string | 建议 | 平台名（供人读） |
+| `followers_count` | integer | 建议 | 粉丝数 |
+| `interactions` | integer | 可选 | 近 30 天均篇互动 |
+| `issue` | string | 可选 | 关注话题串，如 `"真无线耳机;数码评测;"` |
+| `dataSource` | string | 建议 | 数据来源（`target` / `social` / `AI_LLM`）→ 优先写入 `accountSource` |
+| `score` | number 0-1 | 可选 | 相关度分数；**仅当无 `dataSource` 时**作为 `accountSource` 的回退值 |
+| `page_content` | string | 建议 | 账号描述正文 |
+| `metadata` | object | 强烈建议 | 完整画像对象（`用户画像`、`发文` 等）。**整个 user 对象会原样 JSON 序列化存入 `frofileInfo`**，字段越全，后续页面回显与二次分析越完整 |
+
+## 三、生成规则（生成侧模型必须遵守）
+
+1. **账号必须来自真实数据源**：`userList` 的账号对象必须从账号池（如 `product-account-matching` 技能的 `accounts.json`，用 `query_accounts.py --full` 取完整档案）或对话引用中**原样复制**，禁止虚构 id/name/粉丝数等任何字段。
+2. **ID 不编造**：`taskId` / `actionId` 只能取自当前对话上下文；用户没给就先问，不要猜。
+3. **同名覆盖语义要告知**：目标系统里已存在同名 `targetAudience` 时，执行脚本会**先删除旧受众（连带其传播节点关系表与脆弱点关联）再新建**。生成前如已知会覆盖，需在回复中向用户说明。
+4. **群体划分有依据**：`targetAudience` 的划分角度（垂类/场景/人群）与 `recReason` 的理由需与账号池数据（内容垂类、关注话题、发文、受众画像）对得上，理由中可引用具体账号名。
+5. **输出为纯 JSON**：写入 `.json` 文件时最外层就是对象，不要包裹 markdown 代码块、注释或多余文本。
+6. **数量适中**：单次建议 2-6 个受众组，每组 3-15 个账号；超出时按 `score` 与推荐优先级裁剪。
+
+## 四、校验失败常见原因
+
+脚本会前置校验载荷，以下错误会直接退出（不做任何写入）：
+
+- `taskId` / `actionId` 不是整数（如传了 `"101"` 字符串）
+- `audienceList` 为空或缺失
+- 某组 `targetAudience`（或 `groupName`）为空/纯空格
+- 某组 `userList` 不是数组（如传了对象或字符串）

+# add-audience 技能 · 安装与调用说明
+
+把「添加受众目标」的完整接口链路封装给大模型调用：模型写好受众 JSON → 脚本登录任务系统 → 自动执行查重、删除同名（含关系表）、创建受众与账号关联 → 把每个接口的入参与调用结果如实回报给用户。
+
+## 一、安装
+
+**方式 A（推荐）**：在技能管理界面上传 `add-audience.skill`（本质是 zip，内含 `add-audience/` 目录：SKILL.md + config + scripts）。
+
+**方式 B（手工）**：把 `add-audience/` 目录解压到 DeerFlow 后端的 `skills/custom/` 下，然后调用一次 `POST /skills/reconcile-custom` 收编注册。
+
+安装后技能名：`add-audience`。若安装到 public，文档中的 `/mnt/skills/custom/...` 路径对应换成 `/mnt/skills/public/...`。
+
+## 二、配置（config/audience_api.json）
+
+| 配置项 | 默认值 | 说明 |
+| --- | --- | --- |
+| `base_url` | `http://127.0.0.1:4913` | 任务系统地址（到端口，不带 `/api`）；按实际环境修改，如 `http://192.168.1.11:3912` |
+| `username` / `password` | `admin` / `ch@user` | 登录账号，取自前端登录页写死的默认值，可自行修改 |
+| `auth.*` | `/api/auth/login` + `Authorization: Bearer {token}` | 登录路径、token 字段与请求头拼装规则，一般不用动 |
+| `endpoints.*` | `/api/task/task-action-design` 等 | 完整链路涉及的全部接口路径 |
+| `request.verify_ssl` | `false` | **已关闭 HTTPS 证书校验**，适配自签证书内网；公网环境建议改 `true` |
+| `request.timeout_seconds` | `30` | 单请求超时 |
+
+环境变量覆盖：`AUDIENCE_API_BASE_URL`、`AUDIENCE_API_USERNAME`、`AUDIENCE_API_PASSWORD`、`AUDIENCE_API_VERIFY_SSL`。
+
+## 三、鉴权与请求头
+
+1. 脚本先 `POST {base_url}/api/auth/login`，请求体 `{"username": "...", "password": "..."}`；
+2. 从响应取 `access_token`；
+3. 后续所有业务请求附加请求头 `Authorization: Bearer {access_token}`（即 `auth.header_name` + `auth.header_template`）。
+
+证书校验通过 Python ssl 上下文关闭（`verify_ssl=false` 时），HTTPS 自签名证书可直接访问。
+
+## 四、完整调用链
+
+对载荷中的每个受众组依次执行：
+
+| 步骤 | 接口 | 说明 |
+| --- | --- | --- |
+| 1 | `POST /api/auth/login` | 登录换 token |
+| 2 | `GET /api/task/task-action-design?filter=taskId&filter=actionId` | 查当前行动下已有受众（查重） |
+| 3a | `GET /api/task/task-action-design-pathway-relation?filter=actionId` | 查关系表，找同名受众的 pathwayId |
+| 3b | `DELETE /api/task/task-action-pathway-account/{pathwayId}` | **逐条删除关系表记录**（同名时） |
+| 3c | `DELETE /api/task/task-action-design/deleteDesignVulns?designId={id}` | 删除受众关联脆弱点（同名时） |
+| 3d | `DELETE /api/task/task-action-design/{id}` | 删除同名旧受众本身 |
+| 4 | `POST /api/task/task-action-design` | 创建受众目标，`parentTargetAudience` 固定 `大模型生成`，`recReason` 自动清洗 `<n>` 引用标记 |
+| 5 | `POST /api/task/task-action-design-account`（每账号一次） | 字段映射：`accountId←user.id`、`accountName←user.name`、`accountPlat←user.platformType`、`accountSource←user.dataSource`（缺失回退 `user.score`）、`frofileInfo←整个user对象JSON`、`designId←步骤4返回id` |
+
+## 五、载荷格式
+
+```json
+{
+  "taskId": 101,
+  "actionId": 201,
+  "audienceList": [
+    {
+      "targetAudience": "18-30岁智能穿戴尝鲜用户",
+      "recReason": "对新形态设备接受度高……",
+      "userList": [ { "id": "...", "name": "...", "platformType": 1, "dataSource": "target", "...": "完整user对象" } ]
+    }
+  ]
+}
+```
+
+`targetAudience` 也可写作 `groupName`（对齐前端对话链路字段名）。
+
+## 六、输出与验证
+
+脚本 stdout 输出单段 JSON：
+
+- `入参摘要`：taskId/actionId 与各受众组（名称、清洗后理由、账号数）
+- `calls`：每个接口的 method/url/请求体（密码、token 脱敏）/HTTP 状态/响应
+- `groups`：每组结果（designId、新增账号数、删除的旧受众及关系表记录数）
+- `summary` / `人读摘要`：统计与人读结论
+
+验证是否真正入库：`GET {base_url}/api/task/task-action-design?filter=taskId||$eq||{taskId}` 与 `.../task-action-design-account?...` 应能看到新建记录。
+
+## 七、注意事项
+
+- 密码明文存于 config，部署环境请控制文件访问权限，或改用环境变量注入。
+- 同名受众默认「先删后建」（与前端对话链路一致）；需要跳过语义时应先改造脚本再加策略参数。
+- 业务失败（如创建受众返回非 201）时脚本继续处理其余受众组，整体 `success=false`，退出码 2；登录失败立即退出，退出码 1。
