 This drops `skills/agent-browser` (and the specialized `skill-data/{core,electron,slack,dogfood,agentcore,vercel-sandbox}`) into your project so your AI agent gets the right usage patterns and pre-approved bash permissions for `agent-browser`, `agent-browser-stealth`, and `abs`.

-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.
+Attaching uses the Chrome DevTools Protocol, which Chrome only exposes when it is
+**launched with a remote-debugging port**. This is a startup flag, not a setting
+— the `chrome://inspect` toggle alone is **not** enough (it only enables target
+discovery, not the CDP attach).
+
+**Recommended — fully quit Chrome, then relaunch with the port:**
+
+```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 run `agent-browser open <url>` — it auto-discovers the port and attaches.
+On first attach, **Chrome 136+ shows an "Allow remote debugging?" dialog — click
+Allow once** (it persists for that Chrome session).
+
+**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.

-If you need a separate browser (CI, testing, etc.):
+Spawn a separate browser instead of attaching to your running Chrome:
 
 ```bash
+# Throwaway: fresh, EMPTY profile — no cookies, no login (good for CI/testing)
 agent-browser --launch open https://example.com
+
+# Keep your login: launch with your real Chrome profile (cookies/sessions intact)
+agent-browser --launch --profile auto open https://x.com/home
+# or name it explicitly: --profile Default / --profile "Profile 1"
 ```
 
+> ⚠️ Plain `--launch` (no `--profile`) uses a **temporary empty profile** — you will
+> NOT be logged into anything. For logged-in sites use `--profile auto` (picks the

+### 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). |

+
+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.

+// agent-browser connect — MV3 service worker.
+//
+// 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.

+<h3>名称 / Name</h3>
+<pre>agent-browser connect</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 connect 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><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">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">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>
+  <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。

+
+<p><strong>Summary: this extension collects no personal data, contains no analytics or
+trackers, and sends nothing to any remote server.</strong> It is a local bridge that lets the
+user's own <code>agent-browser</code> command-line tool, running on the same computer, drive the
+user's logged-in Chrome.</p>
+
+<h2>What the extension does</h2>
+<p>agent-browser connect pairs Chrome with the locally-installed <code>agent-browser</code> CLI over
+Chrome <em>native messaging</em> (a local inter-process channel; no network socket, no token). When
+the user issues an automation command in the CLI, the extension relays Chrome DevTools Protocol
+operations to the tab the user targets. Everything happens on the user's machine, initiated by the
+user.</p>

 submits, dynamic re-renders, dialog opens. Always re-snapshot before your
 next ref interaction.
 
+## 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:
+`agent-browser extension install` once, load `extensions/ab-connect` in
+`chrome://extensions` once (a GUI step you can perform with a **computer-use /
+GUI-automation tool** like the `cua-driver` skill — see
+`references/commands.md` → "Drive your real, logged-in Chrome"), then
+`agent-browser extension connect`. After that it's zero-confirmation, zero-token
+CLI. Use `--launch` instead when a fresh, isolated browser is fine.
+
+## 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)"

-Rule of thumb: snapshot + `@eN` refs are fastest and most reliable for
-AI agents. `find role/text/label` is next best and doesn't require a prior
-snapshot. Raw CSS is a fallback when the others fail.
+Escalation ladder: snapshot + `@eN` refs are quickest for straightforward
+pages → `find role/text/label` when you'd rather skip the snapshot → raw CSS

+occluded clicks). Don't retry a flaky structured locator three times; drop to
+`eval` and act on the DOM directly.
+
+`click` auto-scrolls into view and, if the coordinate click is occluded, falls
+back to a DOM `.click()`. If a click *reports success but nothing happened* —

+### 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"`.

+## 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
+```
+Then load the extension **once** — this is 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`
+
+**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.
