+# OpenCLI
+
+> **Make any website your CLI.** 操控 Chrome 无风控风险，复用登录，CLI 化全部网站。
+
+OpenCLI 是一个 AI Native 的 CLI 工具，通过 Chrome 浏览器 + Playwright MCP Bridge 扩展，将任何网站变成命令行工具。
+
+## ✨ 特性
+
+- 🌐 **CLI 化全部网站** — 支持 Bilibili、知乎、GitHub、Twitter、V2EX、Hacker News 等
+- 🔐 **零风控风险** — 复用 Chrome 已登录状态，无需存储密码
+- 🤖 **AI Native** — AI agent 可直接探索网站并自动生成新命令
+- 📝 **声明式 YAML** — 用 YAML 定义 pipeline，无需写代码
+- 🔌 **TypeScript 扩展** — 复杂场景用 TS 编写适配器
+
+## 🚀 快速开始
+
+```bash
+# 安装依赖
+cd ~/code/ai-native-cli && npm install
+
+# 列出所有命令
+npx tsx src/main.ts list
+
+# 公共 API（无需浏览器）
+npx tsx src/main.ts hackernews top --limit 10
+npx tsx src/main.ts github search --keyword "typescript"
+
+# 浏览器命令（需要 Chrome + Playwright MCP Bridge 扩展）
+npx tsx src/main.ts bilibili hot --limit 10
+npx tsx src/main.ts zhihu hot --limit 10
+npx tsx src/main.ts twitter trending --limit 10
+```
+
+## 📋 前置要求
+
+浏览器命令需要：
+1. Chrome 浏览器正在运行
+2. 安装 [Playwright MCP Bridge](https://chromewebstore.google.com/detail/playwright-mcp-bridge/mmlmfjhmonkocbjadbfplnigmagldckm) 扩展

+
+## 安装
+
+```bash
+cd ~/code/ai-native-cli
+npm install
+```
+
+## 使用方式
+
+```bash

+
+## 前置要求
+
+浏览器命令需要：
+1. Chrome 浏览器正在运行
+2. 安装 [Playwright MCP Bridge](https://chromewebstore.google.com/detail/playwright-mcp-bridge/mmlmfjhmonkocbjadbfplnigmagldckm) 扩展
+3. 点击扩展图标批准连接
+
+公共 API 命令（hackernews、github search）无需浏览器。
+
+## 内置命令
+
+### 数据查询
+
+```bash
+# Bilibili
+opencli bilibili hot --limit 10          # B站热门视频
+opencli bilibili search --keyword "rust"  # 搜索视频
+opencli bilibili me                       # 我的信息

+opencli bilibili history --limit 20       # 观看历史
+opencli bilibili feed --limit 10          # 动态时间线
+opencli bilibili user-videos --uid 12345  # 用户投稿
+
+# 知乎
+opencli zhihu hot --limit 10             # 知乎热榜
+opencli zhihu search --keyword "AI"      # 搜索
+
+# GitHub
+opencli github trending --limit 10       # GitHub Trending
+opencli github search --keyword "cli"    # 搜索仓库（无需浏览器）
+
+# Twitter/X
+opencli twitter trending --limit 10      # 热门话题
+
+# V2EX
+opencli v2ex hot --limit 10              # 热门话题

+
+### 管理命令
+
+```bash
+opencli list                # 列出所有可用命令
+opencli list --json         # JSON 格式输出
+opencli validate            # 验证所有 CLI 定义
+opencli validate bilibili   # 验证指定站点
+```
+
+### AI 工作流（为 AI Agent 设计）
+
+```bash
+opencli explore <url>                 # 探索网站，生成 API 发现成果物
+opencli synthesize <site>             # 从探索成果物合成候选 CLI
+opencli generate <url> --goal "hot"   # 一键：探索 → 合成 → 注册
+opencli verify <site/name> --smoke    # 验证 + Smoke 测试
+```
+
+## 输出格式
+
+所有命令支持 `--format` / `-f` 选项：
+
+```bash
+opencli bilibili hot -f table   # 默认表格
+opencli bilibili hot -f json    # JSON
+opencli bilibili hot -f md      # Markdown
+opencli bilibili hot -f csv     # CSV
+```
+
+## 调试
+
+```bash
+opencli bilibili hot -v         # 显示 pipeline 每步详情
+```
+
+## 创建新的 CLI 适配器
+
+### YAML 方式（声明式，推荐）
+
+在 `src/clis/<site>/<name>.yaml` 创建文件：
+
+```yaml
+site: mysite
+name: hot
+description: Hot topics on mysite
+domain: www.mysite.com
+strategy: cookie        # public | cookie | header | intercept | ui
+browser: true
+
+args:
+  limit:
+    type: int
+    default: 20
+    description: Number of items
+
+pipeline:
+  - navigate: https://www.mysite.com
+
+  - evaluate: |
+      (async () => {
+        const res = await fetch('/api/hot', { credentials: 'include' });
+        return await res.json();
+      })()
+
+  - select: data.items
+
+  - map:
+      rank: ${{ index + 1 }}
+      title: ${{ item.title }}
+      score: ${{ item.score }}
+
+  - limit: ${{ args.limit }}
+
+columns: [rank, title, score]
+```
+
+### TypeScript 方式（编程式，更灵活）
+
+在 `src/clis/<site>/<name>.ts` 创建并在 `clis/index.ts` 中 import：
+
+```typescript
+import { cli, Strategy } from '../../registry.js';
+
+cli({
+  site: 'mysite',
+  name: 'search',
+  strategy: Strategy.COOKIE,
+  args: [{ name: 'keyword', required: true }],
+  columns: ['rank', 'title', 'url'],
+  func: async (page, kwargs) => {
+    const data = await page.evaluate(`
+      async () => {
+        const res = await fetch('/api/search?q=${kwargs.keyword}', { credentials: 'include' });
+        return await res.json();
+      }
+    `);
+    return data.items.map((item, i) => ({
+      rank: i + 1,
+      title: item.title,
+      url: item.url,
+    }));
+  },
+});
+```
+
+## Pipeline 步骤参考
+
+| 步骤 | 说明 | 示例 |
+|------|------|------|
+| `navigate` | 导航到 URL | `navigate: https://example.com` |
+| `fetch` | HTTP 请求（使用浏览器 cookie） | `fetch: { url: "...", params: { q: "${{ args.keyword }}" } }` |
+| `evaluate` | 执行 JavaScript | `evaluate: \| (async () => { ... })()` |
+| `select` | 选取 JSON 路径 | `select: data.items` |
+| `map` | 映射字段 | `map: { title: "${{ item.title }}" }` |
+| `filter` | 过滤 | `filter: item.score > 100` |
+| `sort` | 排序 | `sort: { by: score, order: desc }` |
+| `limit` | 限制数量 | `limit: ${{ args.limit }}` |
+| `snapshot` | 获取页面快照 | `snapshot: { interactive: true }` |
+| `click` | 点击元素 | `click: ${{ ref }}` |
+| `type` | 输入文本 | `type: { ref: "@1", text: "hello" }` |
+| `wait` | 等待 | `wait: 2` 或 `wait: { text: "loaded" }` |
+| `press` | 按键 | `press: Enter` |
+
+## 模板语法
+
+使用 `${{ expression }}` 进行模板替换：
+
+```yaml
+# 引用参数
+${{ args.keyword }}
+${{ args.limit | default(20) }}
+
+# 引用当前 item（在 map/filter 中）
+${{ item.title }}
+${{ item.data.nested.field }}
+
+# 索引（从 0 开始）
+${{ index }}
+${{ index + 1 }}
+```
+
+## 环境变量
+
+| 变量 | 默认值 | 说明 |
+|------|--------|------|
+| `OPENCLI_BROWSER_CONNECT_TIMEOUT` | 30 | 浏览器连接超时（秒） |
+| `OPENCLI_BROWSER_COMMAND_TIMEOUT` | 45 | 命令执行超时（秒） |
+| `OPENCLI_BROWSER_EXPLORE_TIMEOUT` | 120 | Explore 超时（秒） |
+| `OPENCLI_EXTENSION_LOCK_TIMEOUT` | 120 | 扩展锁超时（秒） |
+| `PLAYWRIGHT_MCP_EXTENSION_TOKEN` | — | 自动批准扩展连接 |
+
+## 错误排查
+
+| 错误 | 解决方案 |
+|------|----------|
+| `npx not found` | 安装 Node.js: `brew install node` |
+| `Timed out connecting to browser` | 1) 确认 Chrome 已打开 2) 安装 Playwright MCP Bridge 扩展 3) 点击扩展图标批准 |
+| `Extension lock timed out` | 等待其他 opencli 命令完成，浏览器命令需串行运行 |
+| `Request timed out` | 增大 `OPENCLI_BROWSER_COMMAND_TIMEOUT` 或检查网络 |
