Cdpm

Saves the page as a PDF (receipts, articles, etc.). Without path, saves to the user's Downloads folder named after the page title. Doesn't change the screen or window.

Lists or answers Chrome permission bubbles ("site wants to: access other apps and services on this device / show notifications / know your location…"). They are browser UI: not in snapshot/screenshot, page tools can't click them, and the page often waits until they are answered. The header warns when one is open. Without button: shows the open bubbles with their exact button names. With button: presses that button (exact name as listed, e.g. "허용", "Allow", "Block", "Allow while visiting the site"). Windows, windowed slots only.

Description is built at runtime.

Reloads the page (same as Chrome reload). ignore_cache=true bypasses the cache. Careful: unsaved user input on the page is lost.

Captures the visible area of the tab as PNG, even background tabs (without switching). Never changes window size or viewport, so full-page capture is unsupported (scroll then capture, or use snapshot/text).

Scrolls a ref element into view, or by dy pixels (positive = down, negative = up, default 600). Reports the actual resulting position.

Picks an option in a <select> dropdown (by value or visible text; partial match OK). Focuses the dropdown and moves with keys (arrow keys on Windows/Linux, typing the first letters on macOS), so the page gets real events and no list popup opens. If nothing matches, lists the available options.

Reads the tab as accessibility-tree text. Clickable/typable elements get refs like [e12]. Long pages are split; only page 1 (top) is shown (page=2 to continue; refs stay the same across pages). find="text" shows only matching elements with their parent context; ref="e40" shows only that element's subtree. Refs change when the page changes, so re-snapshot before acting.

Shows running Chrome slots (1-30) with their tabs, opener, last action and one-line summary. Pass slot for just that slot.

Closes a tab. tab is required.

Opens a new tab in the slot and returns its ID. When agents share a slot, open your own tab and work only by its ID to avoid mixing.

Brings a tab to the front of its Chrome window. Changes what the user sees, so use only when the user wants it. (Background tabs can be read, operated and captured; no need to bring them forward to work.)

Slot tab list: number, ID, title, URL, opener, last action, per-tab summary (updated only by actions with summary). "·front" marks the tab currently in front in its window (one per window).

Reads the page body text (main/article if present). With ref, only that element's text. Shorter and easier than a snapshot for articles/documents. Use page for long text.

Types text into a ref element, sending real key events (keydown/keypress/input/keyup) per character like a human. clear=true clears existing content; submit=true presses Enter after. Verifies the resulting value and reports a mismatch. fast=true inserts very long text at once without key events. Date/time inputs get the value set directly in their format (time "19:30", date "2026-10-08"; change event then has isTrusted=false).

Puts files into a file input (no OS file picker shown to the user). Give ref of the file input (<input type=file> or its label), or for a site's custom "attach" button, click it first with browser_click (CDPM intercepts the picker) and call without ref. The site gets the same events as a human file pick.

Waits until text appears; gone: that text disappears; url: the URL changes; enabled: that button/input becomes enabled; response: a network response for that URL completes (returns its body); network_idle: the network goes quiet; otherwise for seconds. For SPAs (search results, lists, etc.), instead of reading the page, getting the data response (JSON) with response="/api/search" after a click is faster and more accurate (it searches from this agent's last action on that tab, so responses that arrived during the click are caught). Only reads, never touches the page, so the user's input is not …

Shows your unread messages. With wait (seconds), waits up to that long for a new message (for real-time conversation). Messages already delivered in another tool's header are not unread; when there are no new ones, recently received ones are noted for reference.

Use only when the user says to pause (e.g. "pause 3"); agents never call it on their own. All action tools on the slot are refused and any browser_wait in progress stops at once. An action already sent to Chrome finishes. Reading still works. Applies immediately to agents in other Claude sessions too. all=true pauses every running slot.

Use only when the user says to resume (e.g. "continue 3"); the agent owning a paused slot never calls it on its own. Unpauses and messages every agent on the slot to wake it (agents re-read the page and continue). all=true resumes every paused slot.

Sends a message to other agents (real-time collaboration). slot = the slot the recipient owns (to reach another slot's agent, use that slot number). Omit to to send to everyone on that slot. Recipients get it instantly if waiting in slot_inbox wait, otherwise in their next tool result header (a running browser_wait stops at once). When you finish a step, notify waiting agents right away.
