chore(release): 0.27.0-fork.37 — complete humanize (bbox jitter + wheel/drag easing)

Completes the humanize suite:
- Clicks land on a jittered point inside the element's box (Fast/Human) instead
  of its exact centre. `resolve_element_center` now also returns the element
  width/height (box_model_dims); the CSS-selector path reports zero size → land
  on centre (no jitter, no regression). Jitter is clamped to the inner box so the
  click never misses.
- Wheel scrolls split into eased, jittered segments (humanize::scroll_segments,
  unit-tested) instead of one instant jump.
- Drag follows the curved trajectory at Fast/Human (linear 10-step at Off).

Off is unchanged throughout. 9/9 unit tests; verified headless — jittered click
still lands (→ iana.org), segmented scroll moves the page.

 Stealth fork of [agent-browser](https://github.com/vercel-labs/agent-browser) — connects to your real Chrome, shares your login sessions, and is undetectable by anti-bot systems.
 
 For basic usage, commands, and API reference, see the [upstream documentation](https://github.com/vercel-labs/agent-browser).
 
+## Give your AI agent the browser you already live in
+
+**No fresh Chrome. No re-login. No "are you a robot?" walls.**
+
+agent-browser-stealth points **any** agent — Claude Code, Cursor, Codex, your own scripts — at the **Chrome you're already signed into everything on**. It clicks in *your* window, so you watch it work and grab the wheel the moment it hits a 2FA prompt or captcha. And because it's literally your real browser (over a one-click extension, native messaging — no debug port), sites read it as 100% human: **[CreepJS scores it 0% bot](#anti-detection).**
+
+**Why not just use…**
+
+- **Playwright / Puppeteer / browser-use?** They boot an *empty* browser — so you redo every login, fight every captcha, and still get flagged as automation. We use the session you already have.
+- **Claude's Chrome extension?** Great, but it only drives Claude. This drives *any* agent or CLI.
+- **A raw `--remote-debugging-port`** (web-access, etc.)? Chrome 136+ pops **"Allow remote debugging?"** on *every* connect. This never does — one-click Store extension, native messaging.

+## How it works
+
+![how it works](assets/how-it-works.png)
+
+Your **agent-browser CLI** talks to a tiny **browser extension** over Chrome
+**native messaging** — a local inter-process channel, *no network socket, no
+token, no remote server*. The extension uses `chrome.debugger` to drive the tabs
+you target in **your own, already-logged-in Chrome**, then hands results back to
+the CLI. Everything stays on your machine.
+
+![architecture](assets/architecture.png)
+
+Each `--session` gets its **own colored Chrome tab group**, so multiple agents
+can share one real browser concurrently without stepping on each other — or your
+own tabs.
+
+## Why the extension (not a raw debug port)
+
+Other local tools drive Chrome over a raw `--remote-debugging-port` (CDP). Since
+**Chrome 136**, every such connection pops a blocking **"Allow remote debugging?"**
+consent dialog — and the port has to be enabled up front. Our extension uses
+native messaging instead: **install once, then zero per-use confirmation.**
+
+| | **agent-browser-stealth** (this extension) | web-access (raw CDP port) | Claude in Chrome (chrome.debugger) |
+|---|---|---|---|
+| Connect method | native messaging — no port, no token | `--remote-debugging-port` | `chrome.debugger` |
+| **"Allow remote debugging?" popup** | **never** ✅ | **every connection** 🔴 | no |
+| Uses your real login | yes | yes | yes |
+| `Runtime.enable` (CDP) leak¹ | **off by default → clean** ✅ | domain enabled | n/a |
+| CreepJS stealth score² | **0% stealth · 0% headless** ✅ | real Chrome | real Chrome |
+| Per-session tab groups / concurrent agents | **yes** ✅ | no | no |
+| Built for the agent-browser CLI | yes | a separate proxy | a single-app assistant |
+
+> ¹ Verified against [rebrowser-bot-detector](https://bot-detector.rebrowser.net/):
+> our relay reports `runtimeEnableLeak: 🟢 No leak` and `navigatorWebdriver: 🟢`.
+> ² Verified against [CreepJS](https://abrahamjuliot.github.io/creepjs/) on the
+> connected real-Chrome path — see [Anti-detection](#anti-detection).
+>
+> The consent dialog isn't hypothetical: a raw-port tool pops it on **every**
+> attach (Chrome 136+ security). The extension path never does.

-## Setup (one time)
+## Command names
 
-Enable Chrome DevTools Protocol in your Chrome:
+`agent-browser`, `agent-browser-stealth`, and `abs` are **the same binary** —
+`abs` is just a short alias. There is no separate "stealth executable"; stealth
+is a runtime behavior (see [Anti-detection](#anti-detection) below), applied
+automatically based on whether you attach to your real Chrome or `--launch` a
+fresh one.
 
-1. Open `chrome://inspect/#remote-debugging` in Chrome
-2. Toggle the switch on
+## Setup: connect to your Chrome
 
-That's it. This setting persists across Chrome restarts.
+**Recommended — the browser extension (one click, no popups).** Install the
+[**agent-browser-stealth** extension from the Chrome Web Store](https://chromewebstore.google.com/detail/agent-browser-stealth/knfcmbamhjmaonkfnjhldjedeobeafmk),
+then register the local bridge once:
+
+```bash
+agent-browser extension install      # register the native-messaging host (one-time)
+agent-browser open https://x.com/home
+```
+
+`agent-browser open` then drives your real, logged-in Chrome over **native
+messaging** — no debug port, no token, and **no "Allow remote debugging?" dialog,
+ever**. The extension auto-updates and survives Chrome restarts, so it stays
+connected with zero per-use confirmation (ideal for unattended/agent use).
+
+<details>
+<summary>Alternative — raw remote-debugging port (pops a consent dialog)</summary>
+
+Without the extension, agent-browser attaches over the Chrome DevTools Protocol,
+which Chrome only exposes when **launched with a remote-debugging port** (a
+startup flag — the `chrome://inspect` toggle alone is not enough):
+
+```bash
+# macOS
+open -a "Google Chrome" --args --remote-debugging-port=9222
+# Linux
+google-chrome --remote-debugging-port=9222
+# Windows: add --remote-debugging-port=9222 to your Chrome shortcut's target
+```
+
+Then `agent-browser open <url>` auto-discovers the port. On first attach,
+**Chrome 136+ shows an "Allow remote debugging?" dialog** — click Allow once (it
+persists for that Chrome session). The extension above avoids this entirely.
+</details>
+
+**No setup / don't want to touch your real Chrome?** Use
+`agent-browser --launch open <url>` to spawn a fresh isolated stealth browser
+(full anti-detection patches applied; see below). This always works without any
+port setup and is what CI uses automatically.

 ## Anti-detection
 
-When connected to your real Chrome, we inject **zero** JavaScript patches. Your browser's fingerprint is completely genuine.
+<img src="assets/shield.png" alt="stealth shield" width="320" align="right" />
 
-The only thing we do is call `Emulation.setAutomationOverride` via CDP to set `navigator.webdriver = false` at the native Chrome level — undetectable by lie-detection systems like CreepJS.
+When connected to your real Chrome, we inject **zero** JavaScript patches. Your browser's fingerprint is completely genuine. The guiding rule is **native CDP/Chrome overrides over JS lies** — a re-defined getter is itself detectable; a native override isn't.
+
+- `navigator.webdriver = false` via `Emulation.setAutomationOverride` (native, undetectable by CreepJS-style lie tests).
+- **`Runtime.enable` is left OFF by default.** A live `Runtime` domain is a detectable CDP signal (the patchright/rebrowser "runtime leak") — even when attached to your real Chrome. We only enable it when you opt into console/error capture (see below). `click`, `fill`, `eval`, etc. work without it.
 
 **Test results (connected to real Chrome):**
 
 | Test site | Result |
 |---|---|
-| [CreepJS](https://abrahamjuliot.github.io/creepjs/) | 0% stealth, 0% headless |
-| [bot.sannysoft.com](https://bot.sannysoft.com) | All green |
-| [Cloudflare Turnstile](https://nowsecure.nl) | Passed |
+| [CreepJS](https://abrahamjuliot.github.io/creepjs/) | **0% stealth · 0% headless** (no override traces at all) |
+| [bot.incolumitas.com](https://bot.incolumitas.com/) | all checks OK — `overflowTest`, `overrideTest`, `puppeteerExtraStealthUsed`, worker consistency |
+| [bot.sannysoft.com](https://bot.sannysoft.com) | all green |
+| [BrowserScan](https://www.browserscan.net/bot-detection) | Webdriver · User-Agent · CDP all clean |
+| [Cloudflare Turnstile](https://nowsecure.nl) | passed |
 
-When using `--launch` mode (standalone browser), a full suite of 32 stealth patches is applied for headless Chrome.
+`0% stealth` on CreepJS is the key number: because the connect path patches **nothing**, there is no override for a lie-detector to catch. (Dashboards that read `navigator.languages` order or IP geolocation may show a soft "navigator"/"location" flag — that tracks *your real Chrome's* language list and network, not an automation tell.)
+
+When using `--launch` mode (standalone browser), a full suite of stealth patches is applied instead, and it still passes the suite above.
+
+### Verify it yourself
+
+Don't take our word for it — point your connected Chrome at the toughest public detectors and compare:
+
+- **[CreepJS](https://abrahamjuliot.github.io/creepjs/)** — the most thorough fingerprint / lie detector
+- **[bot.incolumitas.com](https://bot.incolumitas.com/)** — behavioral + fingerprint scoring with a public methodology
+- **[BrowserScan](https://www.browserscan.net/bot-detection)** — Webdriver / User-Agent / CDP / Navigator
+- **[bot.sannysoft.com](https://bot.sannysoft.com)** — the classic automation-marker checklist
+- **[pixelscan.net](https://pixelscan.net/)** · **[iphey.com](https://iphey.com/)** — consistency & identity
+
+We deliberately **don't ship our own bot detector** — the strongest, most honest benchmark is the market's best detectors run against your real browser.
+
+### Tuning knobs (environment variables)
+
+| Variable | Default | Effect |
+|---|---|---|
+| `AGENT_BROWSER_CAPTURE_CONSOLE` | off | Enable `Runtime` domain so `console` / `errors` capture page output. Off keeps the stealthiest profile. |
+| `AGENT_BROWSER_TIMEZONE` | unset | `--launch` only. An IANA id (e.g. `Asia/Tokyo`) sets the timezone natively (Intl + Date follow, no JS lie) to match a proxy; `auto` derives one from the locale. |
+| `AGENT_BROWSER_BLOCK_WEBRTC` | auto | `--launch` only. Auto-forces WebRTC through the proxy when one is set (no real-IP leak). `1` hides the local IP without a proxy; `0` opts out. |
+| `AGENT_BROWSER_HIDE_CANVAS` | off | `--launch` only. Adds session-stable canvas/audio fingerprint noise. Off by default (noise is itself a "lie"). |
+| `AGENT_BROWSER_ADAPTIVE_REF` | on | When a saved `@ref` moves and the role/name re-query fails, relocate it by fingerprint similarity (high score + clear margin required, else it fails loudly). `0` disables. |
+| `AGENT_BROWSER_CLICK_MODE` | _(auto)_ | Click strategy. Default scrolls the target into view, dispatches a coordinate click, and falls back to a DOM `.click()` if a floating layer occludes the point. `dom` always uses `.click()` (best for autocomplete/menu items that close on blur); `coord` is strict coordinate-only (hard-fail on occlusion). |

+<img src="assets/fingerprint.png" alt="真实但不可检测的指纹" width="300" align="right" />
+
+**agent-browser**（上游）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。
+
+**agent-browser-stealth** 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。
+
+| | agent-browser | agent-browser-stealth |
+|---|---|---|
+| 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 **agent-browser 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/agent-browser-stealth/main/install.sh | sh
+```
+
+从最新的 [GitHub Release](https://github.com/leeguooooo/agent-browser-stealth/releases) 下载对应平台的预编译二进制，安装 `agent-browser`（以及 `abs` 别名）。无需 npm，无需 token。
+
+### 安装 AI agent skills
+
+```bash
+npx skills add leeguooooo/agent-browser-stealth
+```
+
+把 `skills/agent-browser` 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 [**agent-browser-stealth** 扩展](https://chromewebstore.google.com/detail/agent-browser-stealth/knfcmbamhjmaonkfnjhldjedeobeafmk)，再注册一次本地桥：
+
+```bash
+agent-browser extension install      # 注册原生消息 host（一次性）
+agent-browser open https://x.com/home
+```
+
+之后 `agent-browser 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，agent-browser 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 `agent-browser 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
+agent-browser open https://example.com
+
+# 一切都在你已登录的浏览器里进行
+agent-browser click "Post"
+agent-browser fill "Title" "Hello World"
+agent-browser 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）
+agent-browser --launch open https://example.com
+
+# 保留登录：用你真实的 Chrome profile 启动
+agent-browser --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 |
+|---|---|
+| [CreepJS](https://abrahamjuliot.github.io/creepjs/) | **0% stealth · 0% headless**（零 override 痕迹） |
+| [bot.incolumitas.com](https://bot.incolumitas.com/) | 全部 OK（overflowTest / overrideTest / puppeteerExtraStealth / worker 一致性） |
+| [rebrowser-bot-detector](https://bot-detector.rebrowser.net/) | `runtimeEnableLeak` 🟢 · `pwInitScripts` 🟢 |
+| [bot.sannysoft.com](https://bot.sannysoft.com) | 全绿 |
+
+`--launch` 独立模式下会改用一整套隐身补丁，同样过上述检测。
+
+## 与上游的差异
+
+基于 [agent-browser v0.27.0](https://github.com/vercel-labs/agent-browser)：
+
+- **默认 auto-connect** —— `agent-browser open` 连你的 Chrome 而非启新的
+- **CDP 原生隐身** —— `Emulation.setAutomationOverride` 而非 JS 补丁
+- **双隐身模式** —— 真实 Chrome 零补丁，`--launch` 全补丁
+- **`--launch` / `--new`** —— 显式启动独立浏览器
+- **CI 自动检测** —— 设了 `CI` 环境变量时走独立模式
+
+所有上游功能（命令、快照、截图、录制、标签、会话等）保持一致。

+//! When agent-browser 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.

+// The pure motion maths above are stateless. The daemon drives one active page
+// at a time, so we keep the *current* humanize level and last cursor position
+// in process-global slots rather than threading them through every call site.
+// (The adaptive detector flips the level per navigation; `dispatch_click` reads
+// the level + cursor here, so no signature in the click/type call graph has to
+// change.)

+//! 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 agent-browser 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.

+
+The chrome.debugger attach + CDP Target handling in `background.js` is adapted
+from **openclaw-browser-relay** by chengyixu
+(https://github.com/chengyixu/openclaw-browser-relay, MIT per its README).
+
+Changes for agent-browser-stealth: rebranded to "agent-browser connect"; the
+transport is rewritten from a localhost WebSocket + shared token to Chrome
+**native messaging** (host `com.agent_browser.connect`) — no port, no token,
+Chrome authenticates the extension to the host by id. WebSocket/token/options
+code removed.

+//
+// Bridges the user's real Chrome tabs to the local agent-browser daemon over a
+// Chrome **native messaging** channel (no localhost port, no token: Chrome
+// authenticates this extension to the host by id). It attaches chrome.debugger
+// to eligible tabs and relays CDP both ways via a tiny envelope:
+//   host → ext : {id, method:"forwardCDPCommand", params:{method,params,sessionId}}
+//   ext → host : {id, result|error}                      (command reply)
+//   ext → host : {method:"forwardCDPEvent", params:{sessionId,method,params}}
+//
+// Target/discovery semantics (getTargets/attachToTarget) are emulated on the
+// daemon side; here we just attach tabs and announce them as
+// Target.attachedToTarget so the daemon's CDP client sees them appear.

+
+<p>为什么必须走商店:实测 Chrome 149 在<strong>非企业托管</strong>的 Mac 上,会把"非 Web Store"的 force-install 扩展直接标成 <code>[BLOCKED]</code>。商店扩展不受此限。这也是 codex / claude 扩展都发商店的原因。</p>
+
+<div class="warn">
+  <strong>评审风险(务必知道):</strong> 本扩展用了 <code>debugger</code> 权限,这是 Chrome Web Store 审核最严的权限之一。理由必须写清楚"只在用户本机、用户主动发指令时驱动用户自己的标签页,无远程服务器"。类似工具(如 claude-in-chrome)能过审,但可能被多问一轮、审核时间偏长(几天到一两周)。
+</div>
+
+<h2>一、前置(你来做,一次性)</h2>
+<ol>
+  <li>用一个 Google 账号登录 <code>https://chrome.google.com/webstore/devconsole</code></li>
+  <li>首次需付 <strong>$5</strong> 一次性开发者注册费</li>
+  <li>(隐私政策需要一个公开 URL,见第四节 —— 我可以帮你开 GitHub Pages 托管 <code>privacy.html</code>)</li>

+
+<h2>二、上传</h2>
+<ol>
+  <li>devconsole → <span class="field">New item</span> → 上传 <code>extensions/ab-connect.zip</code></li>
+  <li>上传后确认分配到的 Item ID = <code>ciiljdlhdpfckdcfkphgmfalanpdejep</code>(因为 manifest 里保留了 <code>key</code>,id 会被锁成这个,native messaging 的 allowed_origins 才对得上)。<strong>若 id 不是这个,告诉我,我重签。</strong></li>

+
+<h3>名称 / Name</h3>
+<pre>agent-browser-stealth</pre>
+
+<h3>简介 / Summary（≤132 字符）</h3>
+<pre>Let your own agent-browser CLI drive your logged-in Chrome — a local automation bridge. No remote server, no token.</pre>
+
+<h3>详细描述 / Description</h3>
+<pre>agent-browser-stealth is the in-browser half of the open-source agent-browser 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 agent-browser 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/agent-browser-stealth
+
+You need the agent-browser CLI installed and paired (run: agent-browser extension install) for this
+extension to do anything.</pre>
+
+<h3>类别 / Category</h3>
+<pre>Developer Tools</pre>
+
+<h3>语言 / Language</h3>
+<pre>English</pre>
+
+<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 agent-browser 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 agent-browser 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 agent-browser 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 agent-browser 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>
+</table>
+
+<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>
+  <li><span class="field">Privacy policy URL</span>:填 <code>privacy.html</code> 的公开地址(见下)。</li>
+</ul>
+
+<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>
+<pre>https://leeguooooo.github.io/agent-browser-stealth/extensions/store/privacy.html</pre>
+<p>(部署需 1–2 分钟生效。raw 备用直链:<code>https://raw.githubusercontent.com/leeguooooo/agent-browser-stealth/main/extensions/store/privacy.html</code>。)</p>
+
+<h2>六、截图 / Screenshots（至少 1 张，1280×800 或 640×400）</h2>
+<p>可以截一张 CLI + Chrome 并排的演示图。<em>需要的话我用 cua-driver 截一张合规尺寸的图给你。</em></p>
+
+<h2>七、提交后</h2>
+<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>
+</ol>
+
+<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。
+</div>

+## Before you automate: pick the cheapest tool
+
+Driving a browser is the heavy option. agent-browser earns its keep when you
+need a **real, logged-in browser** — not for reading text off a public page.
+
+| You need | Use |
+|---|---|
+| Discover what exists / find sources | `WebSearch` |
+| Specific facts from a static or public page | `WebFetch` or `curl` (no browser) |
+| Login state, interaction, JS-rendered or anti-bot pages | **agent-browser** (this skill) |
+| A page the user saved before / an internal system | `agent-browser find-url <keywords>` (their bookmarks), then open it |
+| The user's **own already-open, logged-in** Chrome window | the **extension connect** flow (below) |
+
+Don't hand-build deep URLs with query params — links discovered by *interacting*
+with the site carry the right hidden context and dodge anti-bot checks; a
+hand-constructed URL often doesn't.
+
+### Driving the user's real, already-open Chrome (extension)
+
+When the task needs the user's *live* logged-in window (their real session, the
+window they're looking at — not a fresh browser), use the extension connect flow.
+One-time setup:
+1. `agent-browser extension install` — registers the native-messaging host.
+2. Install the **agent-browser-stealth** extension. Easiest (and restart-stable):
+   the **Chrome Web Store**, one-click *Add to Chrome*:
+   <https://chromewebstore.google.com/detail/agent-browser-stealth/knfcmbamhjmaonkfnjhldjedeobeafmk>
+   (Dev fallback: `chrome://extensions` → Developer mode → *Load unpacked* →
+   `extensions/ab-connect`. Load-unpacked can be disabled on Chrome restart, so
+   prefer the Store build for unattended setups.)
+
+Once installed, plain `agent-browser open <url>` auto-connects through the
+extension relay — `auto_connect_cdp` **prefers the live relay over a raw
+`--remote-debugging-port`**, so Chrome 136+'s "Allow remote debugging?" consent
+popup never fires. `agent-browser extension connect` is the explicit form of the
+same path. Zero-confirmation, zero-token. Use `--launch` instead when a fresh,
+isolated browser is fine.
+
+**If you DO hit the "Allow remote debugging?" dialog**, don't keep retrying (every
+attempt re-pops it). One of two things is true:
+
+1. **You're on a stale build.** The relay-preference that avoids this dialog
+   landed in **fork.30**. Run `agent-browser --version`: if it's below
+   `0.27.0-fork.30`, upgrade and retry:
+   ```bash
+   curl -fsSL https://raw.githubusercontent.com/leeguooooo/agent-browser-stealth/main/install.sh | sh
+   ```
+   If `which -a agent-browser` shows more than one install, an old **npm/pnpm**
+   copy (the npm registry lags behind — Releases are the source of truth) may be
+   shadowing the upgraded one; remove the stale copy
+   (`npm rm -g agent-browser-stealth` / `pnpm rm -g agent-browser-stealth`) so the
+   `install.sh` build wins. A tool that bundles its *own* pinned copy
+   (e.g. `node .../agent-browser-stealth@0.24.x/.../agent-browser`) needs that
+   copy upgraded too.
+2. **The extension/relay isn't live.** Tell the user to install the Store
+   extension (one click, above); after that the relay stays up and the dialog
+   never returns.
+
+Each `--session` that connects gets its **own colored Chrome tab group** (named
+after the session) and drives only its own tabs — multiple agents share the one
+real browser without cross-talk, and the user's own tabs are never grouped. CDP
+drives the page without moving the user's mouse/keyboard, so it doesn't fight
+them for control. **Anti-detection ranking: this real logged-in Chrome (extension
+connect) > a headed launched browser > headless (forbidden).** A genuine human
+browser has no headless/automation tells at all, so prefer it for anything
+anti-bot-sensitive.
+
+## Two ways to drive a page — and when to drop to `eval`
+
+You have a **real Chrome with the user's DOM**. Two layers, mix them freely:
+
+1. **Structured** (`snapshot` + `@ref`, `find`, typed actions) — convenient and
+   readable; best for straightforward forms and navigation. But the a11y view is
+   *lossy and fragile*: refs go stale on any change, hidden inputs never show up,
+   overlays can block coordinate clicks.
+2. **eval-first** (`agent-browser eval "<js>"`) — your eyes and hands on the real
+   DOM: read hidden inputs, reach into Shadow DOM / iframes, inspect
+   `form.elements` and `.validity`, extract the exact shape you want, or call
+   `el.click()` directly. **The moment the structured path fights you, drop to
+   `eval` instead of retrying it** — it's the fast way to find *why* something
+   failed (e.g. a hidden `point_choice=none` the UI never exposes).
+
+```bash
+# "what's actually in this form / why won't it submit?"
+agent-browser eval "[...document.forms[0].elements].map(e=>[e.name,e.type,e.value,e.checked])"
+agent-browser eval "document.querySelector('[name=point_choice]')?.value"
+agent-browser eval "[...document.forms[0].elements].filter(e=>!e.validity.valid).map(e=>e.name+': '+e.validationMessage)"

+### Remember a site's quirks (site notes)
+
+A site behaves the same every time you visit it. When you work out something
+durable — a working selector, a URL pattern, a hidden field a form needs, an
+anti-bot trap, what requires login — **write it down so the next run doesn't
+re-discover it.** Keep one markdown file per domain (these are your own notes,
+not shipped with the skill):
+
+```
+~/.agent-browser/site-patterns/<domain>.md
+```
+
+**Before** working on a domain, read its file if it exists (use your normal file
+tools — this is plain markdown you own). Treat it as *hints, not guarantees* —
+sites change; verify before relying. **After** a successful session that taught
+you something durable, create or update it. Suggested shape:
+
+```markdown
+---
+domain: app.example.com
+updated: 2026-06-05
+---
+## Platform traits
+SPA; form renders ~1s after load (wait --text). Cloudflare on /login.
+
+## Working patterns
+- Address pick: the `<li>` closes on blur — select with CLICK_MODE=dom.
+- Submit needs hidden `point_choice` set (eval), the UI never exposes it.
+- Stable selector for "Continue": button[data-testid=submit]
+
+## Known traps (date them)
+- 2026-06-05: @ref to the basket button goes stale after the mini-cart opens;
+  re-snapshot or use `find role button --name "Checkout"`.
+```
+
+This is how repeat visits get fast and reliable instead of re-solving the same
+page every time.

+## Drive your real, logged-in Chrome (extension — zero confirmation)
+
+Chrome 136 blocked `--remote-debugging-port` on the default profile, so to drive
+the user's *existing* logged-in window, agent-browser uses a Chrome **extension**
+over native messaging — no port, no token, no per-use confirmation (the
+codex/claude approach).
+
+One-time setup:
+```bash
+agent-browser extension install        # writes the native-messaging host manifest
+```
+
+The native-messaging host accepts **both** extension origins, so either install
+works — but prefer the Store build:
+
+1. **Chrome Web Store (recommended)** — one-click *Add to Chrome*:
+   <https://chromewebstore.google.com/detail/agent-browser-stealth/knfcmbamhjmaonkfnjhldjedeobeafmk>
+   Restart-stable and auto-updating (store id `knfcmbamhjmaonkfnjhldjedeobeafmk`).
+2. **Load unpacked (dev)** — load `<repo>/extensions/ab-connect` from source;
+   its pinned `key` gives the stable id `ciiljdlhd…`. NOTE: Load-unpacked
+   extensions can be disabled/dropped on Chrome restart (Developer-mode handling),
+   which silently drops the relay — so for unattended setups use the Store build.
+
+For Load unpacked — a GUI step (Chrome's `chrome://extensions` is privileged; the
+CLI can't load an unpacked extension):
+
+> chrome://extensions → enable **Developer mode** (top-right) → **Load unpacked** →
+> select `<repo>/extensions/ab-connect` (it appears in the list as
+> **agent-browser-stealth**)
+
+Once loaded, the relay goes live and plain `agent-browser open <url>` connects
+through it automatically — `auto_connect_cdp` prefers the live extension relay
+over a raw `--remote-debugging-port`, so Chrome 136+'s "Allow remote debugging?"
+consent popup never appears. `agent-browser extension connect` is the explicit
+form of the same path.
+
+**You can do this load step yourself with a computer-use / GUI-automation tool**
+(e.g. the `cua-driver` skill) — drive `chrome://extensions`, toggle Developer
+mode, click *Load unpacked*, pick the folder in the Open dialog. If the extension
+is already loaded, clicking its **Reload** (↻) button after a code change is
+enough. Notes from doing this live: tools that send *synthetic keystrokes* (e.g.
+peekaboo) often don't reach Chrome — **`cua-driver` works** because it reads
+Chrome's accessibility tree and clicks real elements. The native "Open" file
+dialog is the fiddly part; if keystroke entry there fails, ask the user to pick
+the folder (one click). After it loads, Chrome assigns the extension a fixed id
+(pinned in its manifest) and auto-connects the host.
+
+Then, any time (pure CLI, zero confirmation):
+```bash
+agent-browser extension connect        # auto-attaches to the live, logged-in tabs
+agent-browser tab                      # list the real tabs it now controls
+agent-browser tab t3                   # switch the session to one of them
+agent-browser snapshot -i / eval / click ...   # drive it like any session
+agent-browser extension status         # is the host installed?
+agent-browser extension uninstall      # remove the host manifest
+```
+
+Security: the extension↔host link is authenticated by Chrome (extension id); the
+host↔agent-browser CDP link uses an unguessable URL in a 0600 file. Use this when
+you need the user's real cookies/login on their actual machine. (`--extension
+<path>` is unrelated — that loads an extension into a *launched* browser.)
+

+### Finding a page the user saved (`find-url`)
+
+Search the user's local Chrome/Edge **bookmarks** by keyword — for internal
+systems or previously-saved pages that public search can't reach. Local read, no
+browser/daemon needed.
+
+```bash
+agent-browser find-url jira board          # all keywords must match (name or url)
+agent-browser find-url --limit 10 invoices
+agent-browser find-url --browser edge --profile "Profile 1" wiki
+agent-browser find-url grafana --json      # {results:[{name,url,folder}], count}
+```
+
+Results are most-recently-added first. `javascript:`/`data:` bookmarklets are
+skipped. (Visited-history search isn't included yet — bookmarks only.)
+
+### Debugging forms / hidden state with `eval`
+
+The a11y `snapshot` shows visible, interactive elements — it does **not** show
+hidden inputs or a control's actual submitted value. When a form "looks filled"
+but submit-validation rejects it, go straight to the DOM with `eval` instead of
+guessing from the snapshot. This is usually the fastest way to find the real
+problem (e.g. a hidden `point_choice=none` that the visible UI never exposes):
+
+```bash
+# Dump every field's name → value, including hidden inputs and unchecked radios
+agent-browser eval "JSON.stringify([...document.forms[0].elements].map(e=>({name:e.name,type:e.type,value:e.value,checked:e.checked})).filter(e=>e.name))"
+
+# Inspect one hidden field directly
+agent-browser eval "document.querySelector('[name=point_choice]')?.value"
+
+# Why won't it submit? Ask the browser's own validity API
+agent-browser eval "[...document.forms[0].elements].filter(e=>!e.validity?.valid).map(e=>e.name+': '+e.validationMessage)"
+```

+
+### Click reliability
+
+`click` auto-scrolls the target into view first, then dispatches a coordinate
+click. If that fails (a floating layer fails the occlusion guard, or the point
+won't resolve) it falls back to a DOM-dispatched `.click()` on the intended
+element. If a click *reports success but the page didn't react* — common for
+autocomplete/menu `<li>` items that close on the input's blur — retry that one
+with `AGENT_BROWSER_CLICK_MODE=dom` (a DOM dispatch doesn't move focus the way a
+real pointer press does, so the item still selects). `=coord` disables the
+fallback when you specifically want a hard failure on occlusion.
