docs(readme): full-pass audit — purge pre-v1.5 worldview from both READMEs

Two factual errors and a batch of stale-world copy found by auditing the full README against v1.5.0 reality: - "what install does" claimed twitter-cli/rdt-cli are installed by default — they never are (opt-in via --channels); now describes the real flow incl. the channel menu step - zero-config examples listed "read a tweet" — Twitter is tier 1, not zero-config; list now shows truly free channels (incl. bili search) - FAQ rewrites: xiaohongshu (OpenCLI-first, mcp for servers, xhs-cli as legacy fallback), Reddit (login mandatory, OpenCLI first, pinned rdt source), free-cost answer (tool list updated, proxy rescoped to restricted networks) - platform table stops advertising write ops (发推/Post·Comment·Like) — aligned with the skill's fetch-only boundary - bilibili pain-point line updated to the 412 reality - credits gain OpenCLI and xiaohongshu-mcp - README_en: same FAQ/table/doctor-sample fixes Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

 ## 设计理念

-**Agent Reach 是一个脚手架（scaffolding），不是框架。**
+**Agent Reach 是一个能力层（capability layer），不是又一个工具。**

-你给一个新 Agent 装环境的时候，总要花时间去找工具、装依赖、调配置——Twitter 用什么读？Reddit 怎么绕封？YouTube 字幕怎么提取？每次都要重新踩一遍。
+它比任何具体实现高一层——负责**选型、安装、体检、路由**，不负责底层读取本身。读取由 Agent 直接调用上游工具完成，没有包装层。

-Agent Reach 做的事情很简单：**帮你把这些选型和配置的活儿做完了。**
+你给一个新 Agent 装环境的时候，总要花时间去找工具、装依赖、调配置——Twitter 用什么读？Reddit 怎么登录？小红书的 CLI 停更了换什么？每次都要重新踩一遍。Agent Reach 做的事情很简单：**当下最稳的接入方式，我们替你选好、装好、体检好。接入方式会换代（2026 年 3 月一批单平台 CLI 集体停更，我们换了路由），你不用操心。**

-安装完成后，Agent 直接调用上游工具（twitter-cli、rdt-cli、xhs-cli、yt-dlp、mcporter、gh CLI 等），不需要经过 Agent Reach 的包装层。
+### 🔌 每个平台 = 首选 + 备选的有序后端列表

-### 🔌 每个渠道都是可插拔的
-
-每个平台背后是一个独立的上游工具。**不满意？换掉就行。**
+换接入方式 = 调整列表顺序，不是重写代码。`agent-reach doctor` 会告诉你每个平台**当前在用哪个后端**。

-### 抖音 / 小红书脚本提取的可选实现
-
-如果你不只是想“解析抖音视频信息”，还想统一处理：
-
- 抖音视频脚本提取
- 小红书视频笔记脚本提取
- 小红书图文笔记正文 + 图片文字提取
- 固定输出 `script.md` 和 `info.json`
-
-可以把 `douyin` 这个 mcporter alias 指向另一个兼容实现：
-
- [social-post-extractor-mcp](https://github.com/JNHFlow21/social-post-extractor-mcp)
-
-这个实现保留了旧工具名兼容性：
-
- `parse_douyin_video_info`
- `get_douyin_download_link`
- `extract_douyin_text`
-
-同时新增统一工具：
-
- `parse_social_post_info`
- `extract_social_post_script`
-
-所以从 Agent Reach 的视角看，它依然只是一个 `mcporter` 里的 `douyin` server，只是能力更完整。
+> 📌 这些都是「当前选型」，基于真机实测定期复核。某条路失效了我们换下一条——`agent-reach doctor` 永远告诉你现在走的是哪条。

+OpenCLI (github.com/jackwener/opencli) drives the user's real Chrome via a

+zero per-platform configuration, desktop-only (no headless).
+
+Probing notes (verified live):
+  - `opencli doctor` AUTO-STARTS the daemon — a side effect, so health
+    checks must use `opencli daemon status` (pure query) instead.
+  - Exit codes are always 0; status must be parsed from text output.

+    service worker sleeps and any real opencli command wakes it up
+    (verified: status flips disconnected→connected after one call).

-# 微信公众号配置指南
-
-## 功能说明
-读取微信公众号文章。需要 Playwright 来处理微信的反爬机制。
-
-## Agent 可自动完成的步骤
-
-1. 检查 Playwright 是否安装：
-```bash
-python3 -c "import playwright; print('installed')" 2>&1
-```
-
-2. 安装 Playwright + 浏览器：
-```bash
-pip install playwright
-playwright install chromium
-```
-
-3. 安装完成后测试：
-```bash
-curl -s "https://r.jina.ai/https://mp.weixin.qq.com/s/一个测试链接" -H "Accept: text/markdown"
-```
-
-## 需要用户手动做的步骤
-
-请告诉用户：
-
-> 微信公众号的配置很简单，只需要安装一个浏览器组件（约 150MB）。
->
-> 我来帮你安装，你不需要做任何事情。安装过程大约 1-2 分钟。
->
-> 安装好之后就可以直接读取微信公众号文章了，不需要登录。
-
-## Agent 操作流程
-
-1. 安装 Playwright：`pip install playwright`
-2. 安装 Chromium：`playwright install chromium`
-3. 测试：读一篇微信文章
-4. 反馈："✅ 微信公众号已配置！发给我任何公众号文章链接，我都能读取。"

-17 平台工具集合。根据用户意图选择对应分类。
+13 平台、多后端。**本 skill 存在时必须用它访问这些平台，不要自己发明方案。**
+
+## 常驻规则（全程适用）
+
+1. **动手前先体检**：多后端平台（小红书/Reddit/B站/Twitter）先跑
+   `agent-reach doctor --json`，按各平台 `active_backend` 字段选命令组。
+2. **声明你在用什么**：开始干活前说一句「使用 agent-reach 的 X 平台 / Y 后端」。
+3. **失败按 references 里的重试链处理**，不要瞎猜命令。
+4. **全网调研类任务**：组合多平台（Exa 搜索 + Twitter/Reddit 看讨论 + 小红书/B站看中文场景），并行收集再汇总。
+5. **替用户盯版本**：完成一次较大的调研/多平台任务后，顺手跑
+   `agent-reach check-update`（很快，一个 API 调用）。有新版就在收尾汇报里附一句：
+   「Agent Reach 有新版 vX.Y.Z，复制这句话给我即可更新：帮我更新 Agent Reach：
+   https://raw.githubusercontent.com/Panniantong/agent-reach/main/docs/update.md」。
+   不要中断当前任务去更新，也不要重复提醒同一个版本。

-Upstream tools for 17 platforms. Call them directly.
+13 platforms, multiple backends each. **When this skill exists, use it for
+these platforms — do not invent your own approach.**

-Run `agent-reach doctor` to check which channels are available.
+## Standing rules (apply for the whole session)

-## ⚠️ Workspace Rules
+1. **Health-check before acting**: for multi-backend platforms (XiaoHongShu /
+   Reddit / Bilibili / Twitter), run `agent-reach doctor --json` first and
+   pick the command group matching each platform's `active_backend`.
+2. **Announce what you use**: say "using agent-reach, platform X via backend Y"
+   before starting.
+3. **On failure, follow the retry chains in references/** — never guess
+   commands.
+4. **For broad research tasks**: combine platforms (Exa for web search +
+   Twitter/Reddit for discussions + XiaoHongShu/Bilibili for Chinese
+   perspectives), collect in parallel, then synthesize.
+5. **Watch versions for the user**: after finishing a substantial
+   multi-platform task, run `agent-reach check-update` (fast, one API call).
+   If a new version exists, append one line to your wrap-up: "Agent Reach
+   vX.Y.Z is available — paste this to me to update: 帮我更新 Agent Reach：
+   https://raw.githubusercontent.com/Panniantong/agent-reach/main/docs/update.md".
+   Never interrupt the current task to update; never nag about the same version twice.

-**Never create files in the agent workspace.** Use `/tmp/` for temporary output and `~/.agent-reach/` for persistent data.

+小红书、Twitter/X、B站、V2EX、Reddit。

-## 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

+
+# 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。

-### 安装与配置
-
-`douyin-mcp-server` 是 **stdio 模式**的 MCP server，需先安装再注册到 mcporter：
-
-```bash
-# 1. 安装
-pipx install douyin-mcp-server
-
-# 2. 查找安装路径
-pipx runpip douyin-mcp-server show -f 2>/dev/null | grep "Location" \
-  || find ~/.local -name "douyin-mcp-server" 2>/dev/null | head -1
-
-# 3. 注册到 mcporter（使用 stdio 模式，将路径替换为上一步的输出）
-mcporter config add douyin --command "/path/to/douyin-mcp-server" --scope home
-```
-
-> **注意**：`agent-reach install --channels douyin` 暂不支持抖音渠道（抖音在"可选渠道待解锁"列表）。
-> HTTP 模式（`mcporter config add douyin http://localhost:18070/mcp`）**无法正常工作**，请使用上方 stdio 方式。
-
-### 用法
-
-```bash
-# 解析视频信息
-mcporter call 'douyin.parse_douyin_video_info(share_link: "https://v.douyin.com/xxx/")'
-
-# 获取无水印下载链接
-mcporter call 'douyin.get_douyin_download_link(share_link: "https://v.douyin.com/xxx/")'
-
-# 提取视频文案
-mcporter call 'douyin.extract_douyin_text(share_link: "https://v.douyin.com/xxx/")'
-```
-
-> **无需登录**
+> **写操作（发帖/评论/点赞）**: 建议只读。xhs-cli v0.6.x 写操作可能因签名问题返回 406。

 ## Design Philosophy

-**Agent Reach is a scaffolding tool, not a framework.**
+**Agent Reach is a capability layer, not yet another tool.**

-Every time you spin up a new Agent, you spend time finding tools, installing deps, and debugging configs — what reads Twitter? How do you bypass Reddit blocks? How do you extract YouTube subtitles? Every time, you re-do the same work.
+It sits one level above any specific implementation — it handles **selection, installation, health checks, and routing**, not the reading itself. Reading is done by your Agent calling upstream tools directly; there is no wrapper layer.

-Agent Reach does one simple thing: **it makes those tool selection and configuration decisions for you.**
+Every time you spin up a new Agent, you spend time finding tools, installing deps, and debugging configs — what reads Twitter? How do you log into Reddit? What replaces a discontinued XiaoHongShu CLI? Every time, you re-do the same work. Agent Reach does one simple thing: **the most reliable access path for each platform, chosen, installed, and health-checked for you. Access paths come and go (in March 2026 a batch of single-platform CLIs went unmaintained — we re-routed), so you don't have to care.**

-After installation, your Agent calls the upstream tools directly (twitter-cli, rdt-cli, xhs-cli, yt-dlp, mcporter, gh CLI, etc.) — no wrapper layer in between.
+### 🔌 Every platform = an ordered backend list (primary + fallbacks)

-### 🔌 Every Channel is Pluggable
-
-Each platform maps to an upstream tool. **Don't like one? Swap it out.**
+Switching access paths means reordering the list, not rewriting code. `agent-reach doctor` tells you **which backend each platform is currently using**.

-Each channel file only checks whether its upstream tool is installed and working (`check()` method for `agent-reach doctor`). The actual reading and searching is done by calling the upstream tools directly.
+Each channel file **actually probes** its candidate backends in order (not just checking that a command exists) — the first fully working one becomes the active backend, and broken ones come with a fix prescription. The actual reading and searching is done by the Agent calling the upstream tools directly.

-<summary><strong>How to extract scripts from both Douyin and XiaoHongShu with one MCP?</strong></summary>
-
-If you want one MCP server that can handle:
-
- Douyin videos
- XiaoHongShu video notes
- XiaoHongShu image notes
-
-and directly write `script.md` + `info.json`, you can point the existing `douyin` mcporter alias at:
-
- https://github.com/JNHFlow21/social-post-extractor-mcp
-
-It keeps backward compatibility with:
-
- `parse_douyin_video_info`
- `get_douyin_download_link`
- `extract_douyin_text`
-
-and adds unified tools:
-
- `parse_social_post_info`
- `extract_social_post_script`
-
-This is useful when your agent workflow is “paste a link, get a script file”.
+On desktop, prefer **OpenCLI** (`agent-reach install --channels opencli`) — it reuses your browser's logged-in session, so if you've browsed XiaoHongShu you're set; one Chrome Web Store click installs the extension. Then `opencli xiaohongshu search "query"` / `opencli xiaohongshu note URL`. On servers use [xiaohongshu-mcp](https://github.com/xpzouying/xiaohongshu-mcp) (bundled headless browser, QR login). Existing xhs-cli installs keep working as a fallback backend (upstream unmaintained since 2026-03, not recommended for new setups).

+If yes: `agent-reach install --channels opencli` and guide them through the

 ### Step 4: Coexistence (DO NOT uninstall old tools)

-**IMPORTANT: Never uninstall any existing tools the user already has installed.** Old tools (bird, browser_cookie3, miku_ai, etc.) may still be working on the user's machine even if their upstream repos are archived or deleted. Agent Reach supports both old and new tools as fallback. Only install new tools alongside existing ones.
+**Never uninstall tools the user already has.** Retired backends (e.g. yt-dlp
+no longer serves Bilibili; xhs-cli is no longer installed by default) keep
+working as fallbacks where they still function. Agent Reach routes around
+them automatically — removal is the user's call, not yours.

 ### Step 5: Verify

 agent-reach doctor
 ```

+Running `agent-reach doctor` (text mode) also auto-syncs the bundled skill
+(SKILL.md + references) into every detected agent skill directory — no
+separate skill-update step is needed.
+
 Check the doctor output:
- All channels should show ✅ or ⚠️ (with clear instructions)
- If any channel that was working before now shows ❌, investigate:
-  - Twitter: needs `twitter-cli` + browser cookies (run `xhs login` pattern)
-  - Reddit: needs `rdt-cli` (should be installed in Step 3)
-  - XiaoHongShu: needs `xhs-cli` + login (run `xhs login`)
-  - WeChat: should work via Exa (zero config)

-### Step 6: Update SKILL.md (if installed)
+- Every channel shows ✅ / [!] with a clear message, and multi-backend
+  channels (小红书/Reddit/B站/Twitter) report `当前后端：…`
+- If a previously-working channel now shows [X]/error, the message contains
+  the exact fix (e.g. a venv-reinstall prescription) — run it, then re-check
+- `--json` gives the same data machine-readably (`active_backend` per channel)
