-## 小红书 / XiaoHongShu (xhs-cli)
+## 小红书 / XiaoHongShu（多后端）
 
-### 稳定可用的命令
+小红书有三个后端，**先跑 `agent-reach doctor --json` 看 xiaohongshu 的 `active_backend` 是哪个**，再用对应命令组。
+
+### 后端 A：OpenCLI（桌面首选，复用浏览器登录态）
 
 ```bash
-# 搜索笔记（推荐入口）
-xhs search "query"
+# 搜索笔记
+opencli xiaohongshu search "query" -f yaml
 
-# 阅读笔记详情（必须用搜索结果中的 URL 或 ID，不能裸 note_id）
-xhs read NOTE_ID_OR_URL
+# 读笔记正文+互动数据（用搜索结果里的完整 URL，含 xsec_token）
+opencli xiaohongshu note "NOTE_URL" -f yaml
 
-# 查看评论
-xhs comments NOTE_ID_OR_URL
+# 评论（支持楼中楼）
+opencli xiaohongshu comments NOTE_ID -f yaml
 
-# 浏览热门
-xhs hot
+# 首页推荐 feed
+opencli xiaohongshu feed -f yaml
 
-# 推荐 feed
-xhs feed
+# 用户主页公开笔记
+opencli xiaohongshu user USER_ID -f yaml
 ```
 
-### 已知不稳定的命令（v0.6.4）
+> 要求 Chrome 打开且装了 OpenCLI 扩展。报 AUTH_REQUIRED 说明浏览器里没登录小红书，让用户在 Chrome 里登录一次即可。
+
+### 后端 B：xiaohongshu-mcp（服务器场景）
 
 ```bash
-# 以下命令当前可能返回 API error，谨慎使用：
-xhs user USER_ID          # 可能返回 {code: -1}
-xhs user-posts USER_ID    # 可能返回 {code: -1}
-xhs favorites              # 可能返回 API error
+# 未登录时：先查状态，再取二维码给用户扫
+mcporter call 'xiaohongshu.check_login_status()' --timeout 120000
+mcporter call 'xiaohongshu.get_login_qrcode()' --timeout 120000
+
+# 搜索
+mcporter call 'xiaohongshu.search_feeds(keyword: "query")' --timeout 120000
+
+# 笔记详情+评论（feed_id 和 xsec_token 从搜索结果取）
+mcporter call 'xiaohongshu.get_feed_detail(feed_id: "...", xsec_token: "...")' --timeout 120000
 ```
 
-### 重要注意事项
+> 首次调用会自动下载约 150MB 无头浏览器，务必带 `--timeout 120000`。未登录时 search 会挂死，先 check_login_status。
 
-> **安装**: `pipx install xiaohongshu-cli`，然后 `xhs login`（自动从浏览器提取 Cookie）。
+### 后端 C：xhs-cli（存量备选，上游 2026-03 起停更）
+
+```bash
+xhs search "query"          # 搜索
+xhs read NOTE_ID_OR_URL     # 读笔记（必须用搜索结果中的 URL/ID，不能裸 note_id）
+xhs comments NOTE_ID_OR_URL # 评论
+xhs hot                     # 热门
+xhs feed                    # 推荐
+```
+
+> 已知不稳定：`xhs user` / `xhs user-posts` / `xhs favorites` 可能返回 API error（上游停更无人修）。新装用户建议直接走后端 A/B。
+
+### 通用注意事项
+
+> **xsec_token 限制**: 小红书强制 xsec_token 机制，**不能直接用裸 note_id 去读**。正确流程：先搜索/feed 拿结果，再用结果中的完整 URL/ID 去读。三个后端都一样。
 >
-> **xsec_token 限制**: 小红书强制 xsec_token 机制，**不能直接用裸 note_id 去读**。正确流程是：先 `xhs search` 或 `xhs feed` 获取结果，再用结果中的 URL/ID 去 `xhs read`。直接构造 note_id 会被拦截。
+> **频率控制**: 高频请求（批量搜索、深翻评论）会触发验证码，平台限制无法绕过。每次操作间隔 2-3 秒。

-> **频率控制**: 高频请求（批量搜索、深翻评论）会触发验证码，这是平台限制无法绕过。建议每次操作间隔 2-3 秒。

-> **POST 操作风险**: 发帖(post)、评论(comment)、点赞(like) 等写操作在 v0.6.x 可能因签名问题返回 406。如需使用，建议降级到 v0.3.5 (`pipx install xiaohongshu-cli==0.3.5`)。
