Assert a page condition, polling until timeout: element exists/visible (optionally with count or containing text), text on page, tab url/title. Patterns: substring, or "/…/" for regex. Recorded flows replay it as a test.

Click an element by CSS selector or by a ref (n1, n2…) from get_interactives or navigate. A real pointer sequence: it can submit, open a dialog or navigate — use wait_after. Not idempotent; a native confirm() blocks the bridge: handle_dialogs first. Returns page_changed (url, title and DOM deltas: nodes, text, open, expanded, checked, dialogs, focus): the effect, without a screenshot.

Read or write the system clipboard (text). Activates the tab first. write overwrites whatever the user had copied, which is not recoverable.

Open a new tab, optionally at a URL, and make it the implicit target of later commands in this session. Each call creates another tab: reuse a tab_id or navigate() to move an existing one instead of piling up tabs.

Dismiss cookie banners/modal overlays: OneTrust, Cookiebot, Usercentrics, then generic heuristic. Idempotent.

Screenshot cropped to one element or to a viewport region (PNG), optionally enlarged. Read-only. The cheapest image in the set, because it carries only the box you asked for — and with scale the way to read fine print: crop the box, zoom it, verify.

Run JavaScript in the page (MAIN world). Requires the extension's "Allow user scripts" toggle; errors explain setup if disabled.

Read repeated non-tabular structures — product cards, list items, search results — as one record per item: item_selector matches the repeating block, fields map output names to selectors relative to it. Read-only, deterministic, parsed server-side from the main-document HTML.

Batch fill form fields with React-compatible events. Handles input, select, checkbox, radio, and textarea. With submit_selector it also submits, so a repeated call submits twice — not safe to retry blindly. Each field reports value_after and mismatch; page_changed carries the DOM delta.

Where is a setting in an unknown admin panel: follows the panel's menu links (same origin) until a page contains the keyword and reports the menu path. Navigates the tab, leaves it on the page found, stops at max_pages.

Find text on the page: parent selector, context, visibility, position per match. Attaches nearby interactive elements (with refs for click/type_text/hover) for the first visible match.

Full-page capture by scrolling: stitched segments of ~2 viewports (≤1568px), or one image per viewport with stitch=false. Expensive: ~2.7k image tokens per segment, only max_segments returned, the rest via segment_offset. Reading the text you need is cheaper by an order of magnitude — prefer read_page, extract or find_text unless layout is the question.

List frames (main + iframes) with frameId, parent, URL — for the frame_id parameter of DOM tools.

List actionable elements (buttons, links, inputs, [role], [onclick]) with ready-to-use CSS selector, label, position, flags. Prefer this over dumping HTML to discover selectors.

Get page metadata: meta tags, scripts, stylesheets, links, and forms

Check bridge status: extension connection, server mode (primary/relay), port, version

List every open tab with id, url, title, active flag and mine (created by this session). Read-only. Find a tab_id when the implicit target is not the one you mean. include_windows adds position, size, state and type of each window — needed before moving or tiling.

Auto-accept/dismiss future JS dialogs (alert/confirm/prompt), logging them. reset restores native dialogs and returns the log.

Hand the browser to the user for what only a person can do — 2FA, CAPTCHA, login, a choice — and wait: a banner in the page shows your message with Done/Cancel, the call returns on click or timeout, redirects included. pick_element: the user clicks an element and you get its selector. Never type credentials yourself. ask: the user types a reply in the banner ("which of the three?") and you get it as answer. pick_max: with pick_element, up to N elements; the user presses Done when finished.

Hover over an element (mouseenter/mouseover), by CSS selector or ref.

HTTP request sent from the browser, with the logged-in user's cookies: fetches what a server-side request gets a login page for (invoices, authenticated JSON, exports). Text bodies inline (capped by max_length); save_to writes the bytes — the way to read a PDF, since read_page returns nothing on a PDF tab.

Monitor network requests. source=page: XHR/fetch hook (installed on first call); source=browser: all requests incl. static assets; source=websocket: connections and messages. format=har exports HAR 1.2.

Move an existing tab into another window (chrome.tabs.move), keeping id, history and page state; works on chrome-untrusted:// tabs too. The **destination** must be a normal window: out of an app/popup window is fine, into one is refused. A ChromeOS Terminal tab can be pulled out (new_window, window_type popup) but never merged back: extensions cannot create app windows.

Navigate a Chrome tab to a URL. Returns a preview of interactive elements with refs usable in click/type_text/hover.

Send a key to the focused element (or to selector, focusing it first) as a real keydown/keypress/keyup sequence, so framework handlers fire. For typing a value use type_text; this is for Enter, Tab, Escape, arrows and shortcuts. Not idempotent: two calls send the key twice.

Query DOM elements by CSS selector, returning structure, attributes, bounding rect, and computed styles.

Read console messages captured since page load, incl. uncaught errors and unhandled rejections.

Read a form as the user filled it — label, type, value, checked/selected, required-but-empty, browser validity — to check it against the project's documents before an irreversible Submit. Password and card values come back [redacted]. Read-only, on request.

Read the page as text (default), markdown, raw HTML, or accessibility tree. Read-only. markdown keeps headings, links and tables at a fraction of the HTML cost. Expensive on big pages: HTML on a large table costs tens of thousands of tokens for data you filter anyway — prefer extract_table/extract for repeated content, get_interactives for click targets.

Screenshot of the visible viewport only (PNG), at the current scroll position, or one per viewport preset with presets. Read-only. Activates the tab in the background without stealing window focus, then restores the previous tab. Downscaled to ≤1568px: for fine print, element_screenshot with scale.

Scroll. action=to: once to element/coordinates; action=until: repeatedly until element visible, network idle, or no new content (infinite scroll).

Tab lifecycle: close, activate, reload, back, forward, discard, mute, duplicate, close_session (only tabs this session created). close drops unsaved work and cannot be undone — it may be the user's tab. reload drops injected CSS, emulations and hooks. duplicate works where create_tab is forbidden (chrome-untrusted://) and lands in the source window, app windows included. discard replaces the tab id.

Tile Chrome windows over one monitor in equal parts with no gap. Only Chrome windows. The monitor is the one of a window already on it, whose work area is read from a page there: at least one target needs a scriptable tab (not chrome://). Maximized windows are restored first, since maximized ignores bounds.

Put text into an input, textarea or contenteditable, by selector or ref. Replaces the whole value through the native setter (React/Vue controlled inputs register it) and fires input and change. mode=keys emits keydown/input/keyup per character for autocomplete and masked fields: slower, use it only when mode=set leaves the field empty. Returns value_after; mismatch=true means the field did not keep the value: retry with mode=keys.

Set a file on input[type=file] from the server filesystem via DataTransfer (max 10MB).

Block until a condition holds: element, text, function (JS expression; needs the "Allow user scripts" toggle), navigation (mode=spa for client-side routes), network_idle. Polls until timeout (10s element/function, 15s the rest) then **returns `found: false` with a reason instead of raising**: check it, or a failed wait reads as success. Read-only.

Keep watching a page in the background — "tell me when the pipeline is green / the Approve button appears / this number changes" — checked every interval_s by the extension. Events are collected, not pushed: action=poll, or a script blocking on "chrome-bridge watch --wait <name>". Survives extension idling, not a browser restart.

Save the current window arrangement under a name, restore, list or delete. save overwrites silently. Window ids do not survive a browser restart: restore matches windows by the overlap of their tab URLs and reports the ones it cannot recognise instead of guessing.
