chore(release): 1.2.0 — chrome-use test (browser test suites)

feat(test): chrome-use test <suite.yaml> — re-runnable browser test suites
Turn repetitive browser checks into unit-test-style YAML suites. Steps reuse chrome-use's own commands; assertions (url/visible/hidden/text/count/eval) compile to a single truthy `eval`. The runner re-invokes the binary per step (inherits all flag/launch/daemon/ref semantics; the daemon stays up so each step is a fast socket call), launches an isolated browser by default, captures a screenshot on failure, and exits non-zero for CI. `setup: account:` injects a cookie-use login. Ships a `test` skill (skills get test). Unit-tested step/assert compilation.

+
+<sub>最初基于 [vercel-labs/agent-browser](https://github.com/vercel-labs/agent-browser)（Apache-2.0）；现已是独立项目 —— 隐身/扩展中继架构、反检测、humanize、多 agent 隔离与 CLI 都已大幅分化。</sub>
+
+## 把你**已经登录好**的浏览器，交给你的 AI agent
+
+**不用开新 Chrome。不用重新登录。不用跟"你是不是机器人"较劲。**
+
+chrome-use 让**任意** agent（Claude Code、Cursor、Codex、你自己的脚本）直接操作你**已经登录了所有网站**的那个 Chrome。它在**你的窗口里**点击，你看着它干活，撞到 2FA / 验证码的瞬间你接管一下，它接着跑。因为它**就是你的真实浏览器**（一键装的扩展、原生消息、无调试端口），网站眼里它 100% 是人：**[CreepJS 实测 0% 机器人](#反检测)。**
+
+**为什么不用……**
+
+- **Playwright / Puppeteer / browser-use？** 它们开的是**空**浏览器 —— 每个登录你重做、每个验证码你硬扛、最后还被标成自动化。我们直接用你**现成的**会话。
+- **Claude 的 Chrome 插件？** 很好，但**只能给 Claude 用**。我们给**任意** agent / CLI 用。
+- **裸 `--remote-debugging-port`**（web-access 等）？ Chrome 136+ **每次连都弹** "Allow remote debugging?"。我们**永不弹** —— 商店一键装，原生消息。

+
+## 为什么选 chrome-use
+
+<img src="assets/fingerprint.png" alt="真实但不可检测的指纹" width="300" align="right" />
+
+**常规浏览器自动化**（Playwright / Puppeteer，或全新 `--launch`）启动的是空 profile 的全新浏览器：你得重新登录，网站也能看出是自动化。
+
+**chrome-use** 连接你**现有**的 Chrome —— cookies、会话、浏览器指纹全是真的，因为它**就是**你的真实浏览器。
+
+| | 常规自动化 | chrome-use |
+|---|---|---|
+| 浏览器 | 启动新 Chrome | 连接你的 Chrome |
+| 登录态 | 空，要重新登 | 你现有的会话 |
+| 指纹 | 带自动化标记 | 你的真实指纹 |
+| 协作 | 独立窗口 | 同一窗口，随时接管 |
+| 验证码 | Agent 卡住 | 你点一下，Agent 继续 |
+
+## 工作原理
+
+![工作原理](assets/how-it-works.png)
+
+你的 **chrome-use CLI** 通过 Chrome **原生消息（native messaging）** 和一个小**浏览器扩展**通信 —— 这是本机进程间通道，**无网络端口、无 token、无远程服务器**。扩展用 `chrome.debugger` 驱动你指定的标签页（在你**已登录**的 Chrome 里），再把结果交还给 CLI。全程都在你本机。
+
+![架构](assets/architecture.png)
+
+每个 `--session` 拿到**自己的彩色标签组**，多个 agent 共用同一个真实浏览器、互不干扰，也不动你自己的标签页。
+
+## 安装
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/leeguooooo/chrome-use/main/install.sh | sh
+```
+
+从最新的 [GitHub Release](https://github.com/leeguooooo/chrome-use/releases) 下载对应平台的预编译二进制，安装 `chrome-use`（以及 `abs` 别名）。无需 npm，无需 token。
+
+### 安装 AI agent skills
+
+```bash
+npx skills add leeguooooo/chrome-use
+```
+
+把 `skills/chrome-use` 拉进当前项目，让你的 AI agent 拿到正确的用法和预授权的 bash 权限。
+
+## 连接你的 Chrome
+
+**推荐 —— 浏览器扩展（一键，无弹窗）。** 从 Chrome 应用商店安装 [**chrome-use** 扩展](https://chromewebstore.google.com/detail/chrome-use/knfcmbamhjmaonkfnjhldjedeobeafmk)，再注册一次本地桥：
+
+```bash
+chrome-use extension install      # 注册原生消息 host（一次性）
+chrome-use open https://x.com/home
+```
+
+之后 `chrome-use open` 就通过**原生消息**驱动你真实、已登录的 Chrome —— 无调试端口、无 token、**永远不弹 "Allow remote debugging?"**。扩展自动更新、重启不掉，零确认（适合无人值守 / agent 场景）。
+
+<details>
+<summary>备选 —— 裸 remote-debugging 端口（会弹同意框）</summary>
+
+不装扩展时，chrome-use 退回用 CDP 连接，而 Chrome 只在带 remote-debugging 端口启动时才暴露它：
+
+```bash
+# macOS
+open -a "Google Chrome" --args --remote-debugging-port=9222
+# Linux
+google-chrome --remote-debugging-port=9222
+# Windows: 给 Chrome 快捷方式 target 加 --remote-debugging-port=9222
+```
+
+然后 `chrome-use open <url>` 自动发现端口。首次连接 **Chrome 136+ 会弹 "Allow remote debugging?"** —— 点一次 Allow（该 Chrome 会话内持续有效）。上面的扩展则完全避开这个框。
+</details>
+
+## 用法
+
+```bash
+# 连接你的 Chrome 并导航
+chrome-use open https://example.com
+
+# 一切都在你已登录的浏览器里进行
+chrome-use click "Post"
+chrome-use fill "Title" "Hello World"
+chrome-use screenshot ./page.png
+```
+
+Agent 在你的 Chrome 里操作 —— 你能实时看到开标签、加载、点击。任意时刻都能接管（比如手动过验证码），然后让 agent 继续。
+
+### 独立模式（`--launch`）
+
+```bash
+# 临时：全新空 profile —— 无 cookie 无登录（适合 CI / 测试）
+chrome-use --launch open https://example.com
+
+# 保留登录：用你真实的 Chrome profile 启动
+chrome-use --launch --profile auto open https://x.com/home
+```
+
+## 反检测
+
+连接你真实 Chrome 时，我们**零** JS 注入 —— 浏览器指纹完全是真的。指导原则是 **native CDP/Chrome 覆盖优先于 JS 谎言**：被重定义的 getter 本身可被检测，原生覆盖则不会。
+
+- `navigator.webdriver = false` 走 `Emulation.setAutomationOverride`（原生，CreepJS 类说谎检测查不出）。
+- **`Runtime.enable` 默认关闭** —— 活着的 `Runtime` 域是可被检测的 CDP 信号（patchright/rebrowser 的 "runtime leak"），即便连的是你真实 Chrome。只在你主动开启 console/错误捕获时才启用。
+
+**实测结果（连接真实 Chrome，中继路径）：**
+
+| 检测站 | 结果 |
+|---|---|

+
+`--launch` 独立模式下会改用一整套隐身补丁，同样过上述检测。
+
+### 类人输入（行为隐身）
+
+指纹隐身只是一半——最强的反爬厂商（Akamai、PerimeterX、DataDome）还会给**行为**打分。点击时光标瞬移到元素正中心、没有接近轨迹、按下即抬起,这本身就是破绽,**哪怕我们的 CDP 事件是 `isTrusted`**。
+
+开启 humanize 后,光标像手在动:点击走带减速的贝塞尔曲线、落在元素内**偏离正中心**的抖动点;打字用变速的击键间隔;滚动分段缓动;拖拽走曲线。而且**自适应**——每次导航探测页面是否有已知反爬厂商(cookie/脚本/全局变量),命中就自动升到全套类人动作,普通站点保持瞬时(零开销)。
+
+页面自己的 `mousemove` 流看到的(行为检测器分析的正是这个):
+
+| | 轨迹 |
+|---|---|
+| **off**（默认） | 直线 · 死磕正中心 · 瞬时 |
+| **human** | 曲线 · 先慢后快再慢 · 落点偏移 |
+
+用 `--humanize off\|fast\|human` 或 `AGENT_BROWSER_HUMANIZE` 控制。默认 `off`,自适应检测器按页面自动升档。
+
+### 静默操作
+
+操作你的真实 Chrome 不该打断你的工作。agent **全程在后台操作**:新标签后台打开(在自己的彩色会话标签组里),**从不强制把标签拽到前台**,并用 `Emulation.setFocusEmulationEnabled` 让每个 agent 标签照常渲染、`document.hasFocus()` / `visibilityState` 仍报 `visible`。于是截图正常、页面不被降频,"标签全程隐藏"也不会变成新的机器人信号。你在自己的标签里照常工作,agent 在旁边默默干活。(想置顶某个标签仍可显式调用命令。)
+
+## chrome-use 的独特之处
+
+- **默认 auto-connect** —— `chrome-use open` 连你现有的 Chrome 而非启新的
+- **扩展中继传输** —— 一键安装的 Chrome 商店扩展 + 原生消息，无调试端口、无 "Allow remote debugging?" 弹框
+- **CDP 原生隐身** —— 反检测走 Chrome/CDP 覆盖而非 JS 补丁；连真实 Chrome 零补丁，仅 `--launch` 用全补丁
+- **Humanize** —— 类人光标轨迹 + 自适应反爬处理
+- **多 agent 隔离** —— 多个 agent 通过 per-session 标签组共享同一个真实 Chrome，互不串扰
+- **静默运行** —— 后台操作，绝不抢你的前台标签

+//! Human-like input behaviour for stealth.
+//!
+//! When chrome-use drives a real Chrome over CDP, the input events it
+//! dispatches are already `isTrusted` — but a click that teleports the cursor
+//! straight to an element's exact centre, with no approach path and zero delay
+//! between move/press/release, is a behavioural tell that advanced anti-bot
+//! vendors (Akamai, PerimeterX, DataDome) look for.
+//!
+//! This module produces **human-like motion plans** — curved, eased cursor
+//! trajectories and variable keystroke timing — as *pure data*. It performs no
+//! I/O and knows nothing about CDP: callers turn the returned steps into
+//! `Input.dispatchMouseEvent` / `dispatchKeyEvent` calls. Keeping the maths pure
+//! makes the easing/jitter/detection logic unit-testable and deterministic
+//! (every randomised value comes from a caller-supplied seed).
+//!
+//! Design (see brainstorm 2026-06-11):
+//! - Three levels: [`HumanizeLevel::Off`] (instant, today's behaviour),
+//!   `Fast` (a few cheap eased steps), `Human` (full curved trajectory + jitter).
+//! - Baseline is `Off`; the daemon escalates a session to `Human` when
+//!   [`detect_level`] spots a known anti-bot vendor on the page. `--humanize` /
+//!   `AGENT_BROWSER_HUMANIZE` force a fixed level.
+//! - Humanization only changes *how* the cursor reaches a target, never *which*
+//!   element is hit: the landing jitter stays inside the caller-provided bounds.

+//! Relay between the `ab-connect` browser extension and the daemon's `CdpClient`.
+//!
+//! The extension speaks a small CDP-over-WebSocket "envelope" protocol (adapted
+//! from openclaw-browser-relay) and drives the user's real tabs via per-tab
+//! `chrome.debugger`. The daemon's `CdpClient`, however, expects a **browser-
+//! level** CDP endpoint (`Target.getTargets` / `Target.attachToTarget` → a
+//! `sessionId`, then per-session commands). This relay bridges the two: it
+//! tracks the targets the extension reports, answers the browser-level
+//! `Target.*` discovery commands LOCALLY, and forwards everything else to the
+//! extension as `forwardCDPCommand`. That keeps `CdpClient` and `browser.rs`
+//! unchanged.
+//!
+//! ## Multiple clients (concurrent agents on one shared browser)
+//!
+//! Several chrome-use daemons (one per `--session`) can connect to the same
+//! relay/Chrome at once. The extension is a single peer, so the relay must
+//! demultiplex: every forwarded command is re-keyed to a relay-global id mapped
+//! back to the originating client, and the extension's reply is routed to **only
+//! that client** (with its original id restored). Command ids from different
+//! clients therefore never collide, and one client never sees another's command
+//! replies. CDP *events* (no id) fan out to all clients, which ignore events for
+//! sessions they didn't attach.
+//!
+//! This module is the pure translation core (no I/O) so the protocol can be
+//! unit-tested; the tokio WebSocket server that drives it lives alongside.

+
+RULES:
+- You MUST use the agent_browser tool for every browser action. NEVER claim you performed an action without calling the tool.
+- If the user asks you to do something, call the tool first, then describe the result.
+- If a request is outside your capabilities (e.g. system operations), say so honestly. Do not improvise or pretend.
+- One tool call per command. Do not chain with `&&` or `;`.
+- Do not add `--json`.
+- Do not run non-chrome-use programs.
+- Keep responses concise.
+- For screenshots, omit the path argument so they save to the default location (which will be displayed inline). Screenshots from tool calls are ALREADY shown to the user. Do NOT re-display them with markdown image syntax in your text response. Never use `![...]()` to reference screenshots.
+- To create a new session: add `--session <name>` to any command (e.g. `chrome-use --session my-session open https://example.com`). If the session does not exist, it will be created automatically.
+- To use a different browser engine: add `--engine <engine>` (e.g. `chrome-use --session lp-session --engine lightpanda open https://example.com`). Supported engines: chrome (default), lightpanda.
+
+The following skill references describe chrome-use capabilities in detail. Use them when deciding which commands to run and how to approach tasks.

+//! `chrome-use test <suite.yaml>` — a tiny, re-runnable browser test runner.
+//!
+//! Turns repetitive browser checks into unit-test-style suites for the frontend.
+//! A suite is a YAML file of cases; each case is a list of `steps` (which reuse
+//! chrome-use's own commands) followed by `assert`s (which compile to a single
+//! `eval` expression read back as a boolean). The runner drives the session by
+//! re-invoking the chrome-use binary per step, so it inherits every flag /
+//! launch / daemon / `@ref` semantic for free; the daemon stays up for the
+//! session, so each step is just a fast socket round-trip.
+//!
+//! ```yaml
+//! suite: chatgpt smoke
+//! setup:
+//!   - account: chatgpt/huayue        # cookie-use injects this login (optional)
+//! cases:
+//!   - name: home loads logged in
+//!     steps:
+//!       - open: https://chatgpt.com/
+//!       - wait: { load: networkidle }
+//!     assert:
+//!       - url: { contains: chatgpt.com }
+//!       - visible: "#prompt-textarea"

+<h2>三、商店信息(直接复制以下文案)</h2>
+
+<h3>名称 / Name</h3>
+<pre>chrome-use</pre>
+
+<h3>简介 / Summary（≤132 字符）</h3>
+<pre>Let your own chrome-use CLI drive your logged-in Chrome — a local automation bridge. No remote server, no token.</pre>
+
+<h3>详细描述 / Description</h3>
+<pre>chrome-use is the in-browser half of the open-source chrome-use CLI. It lets the
+command-line tool you installed on this same computer automate the Chrome you're already logged
+into — opening pages, clicking, filling forms, reading the DOM — driven entirely by you.
+
+How it works
+- The extension talks ONLY to the local chrome-use CLI over Chrome native messaging (a local
+  inter-process channel — no network socket, no token, no remote server).
+- When you run an automation command, the extension relays Chrome DevTools Protocol operations to
+  the tab you target, then returns the result to the CLI.
+
+Privacy
+- No analytics, no trackers, no data collection.
+- Nothing is sent to any remote server. The only message peer is the local CLI.
+- Source is open (Apache-2.0): https://github.com/leeguooooo/chrome-use
+
+You need the chrome-use CLI installed and paired (run: chrome-use extension install) for this
+extension to do anything.</pre>

+
+<h3>语言 / Language</h3>

+
+<h2>四、隐私实践（Privacy practices 标签页 —— 必填）</h2>
+
+<h3>Single purpose（单一用途）</h3>
+<pre>Bridge the user's locally-installed chrome-use CLI to their own logged-in Chrome so the CLI can
+automate pages the user is working with, entirely on the user's machine and at the user's command.</pre>
+
+<h3>各权限理由 / Permission justifications</h3>
+<table>
+  <tr><th>权限</th><th>理由（复制到对应输入框）</th></tr>
+  <tr><td class="field">debugger</td><td>Attaches the Chrome DevTools Protocol to the user's own active tab so the paired local chrome-use CLI can automate it (navigate, click, read DOM) only while the user is running a command. Commands arrive solely from the local CLI via native messaging; there is no remote endpoint.</td></tr>
+  <tr><td class="field">tabs</td><td>Enumerate and target the correct open tab to attach automation to.</td></tr>
+  <tr><td class="field">tabGroups</td><td>Organizes the tabs the local chrome-use CLI drives into a labeled, colored Chrome tab group per automation session, so the user can see at a glance which tabs are under automation and they stay visually separated from the user's own tabs.</td></tr>
+  <tr><td class="field">nativeMessaging</td><td>The sole communication channel: a local native-messaging connection to the chrome-use CLI installed on the same machine. No network is used.</td></tr>
+  <tr><td class="field">storage</td><td>Persist small local pairing/configuration state for the extension.</td></tr>
+  <tr><td class="field">alarms</td><td>Keep the MV3 service worker alive during longer automation sessions.</td></tr>
+  <tr><td class="field">webNavigation</td><td>Detect page loads/navigations so automation can wait for the right moment before acting.</td></tr>
+  <tr><td class="field">host permissions（若被问）</td><td>The extension declares none; tab access is mediated through the debugger attach the user initiates.</td></tr>

+<h3>数据用途勾选 / Data usage</h3>
+<ul>
+  <li>不勾选任何"collects user data"类别。</li>
+  <li>三个合规声明全部勾选可以为真:不卖数据 / 不挪作无关用途 / 不用于判断信用资质。</li>

+<h2>五、隐私政策 URL</h2>
+<p>商店要求一个公开可访问的隐私政策地址。GitHub Pages <strong>已开启</strong>,直接填这个(渲染好看):</p>

+<ol>
+  <li>提交审核 → 等几天。审核通过且状态变 <em>Published</em> 后告诉我。</li>
+  <li>我会把 <code>extension install</code> 的 force-install <code>update_url</code> 切到商店地址并发布新 fork;之后用户 <code>extension install</code> → 批准一次描述文件 → 静默装好(商店扩展不再 <code>[BLOCKED]</code>);或者用户在商店页一键 <span class="field">Add to Chrome</span>。</li>

+<div class="ok">
+  <strong>今天的临时可用方案:</strong> 在你这台 Mac 上 <code>chrome://extensions</code> → 打开开发者模式 → Load unpacked → 选 <code>extensions/ab-connect</code>,30 秒手动装一次,native messaging + <code>extension connect</code> 立即可用。等商店过审再切静默路径。
