Pinchtab

Pinchtab Skill 🦀

This skill provides efficient, HTTP-based browser control for AI agents using Pinchtab. It's designed for faster, cheaper, and more robust web automation, leveraging accessibility trees for precise interaction and token efficiency.

Functions:

start_server(port=9867, token=None, headless=True)

Starts the Pinchtab HTTP server in the background. If a server is already running, it will attempt to connect to it.

Parameters:

• port (integer, optional): The port Pinchtab should listen on. Defaults to 9867.
• token (string, optional): An authentication token for the Pinchtab API. If not provided, it will attempt to retrieve PINCHTAB_API_TOKEN from secrets.db.
• headless (boolean, optional): If True, Chrome runs in headless mode (no visible window). Defaults to True.

Returns: A string indicating the Pinchtab server status and URL.

stop_server()

Stops the running Pinchtab server process.

Returns: A string indicating the server's shutdown status.

navigate(url, tab_id=None)

Navigates the browser to the specified URL.

Parameters:

• url (string, required): The URL to navigate to.
• tab_id (string, optional): The ID of the tab to navigate. Defaults to the first tab.

Returns: A string indicating successful navigation or an error.

get_snapshot(tab_id=None, filter='interactive', format='text', max_tokens=None, selector=None)

Gets an accessibility tree snapshot of the current page. Optimized for token efficiency.

Parameters:

• tab_id (string, optional): The ID of the tab to snapshot. Defaults to the first tab.
• filter (string, optional): Filter for snapshot. 'interactive' (buttons, links, inputs) or 'full'. Defaults to 'interactive'.
• format (string, optional): Output format. 'text' (indented plain text), 'compact' (one-line-per-node), or 'json'. Defaults to 'text'.
• max_tokens (integer, optional): Truncate output to ~N tokens.
• selector (string, optional): CSS selector to scope the tree to a subtree.

Returns: A string containing the formatted page snapshot.

get_text(tab_id=None, mode='readability')

Gets readable page text, either via readability extraction or raw innerText.

Parameters:

• tab_id (string, optional): The ID of the tab. Defaults to the first tab.
• mode (string, optional): Extraction mode. 'readability' (strips nav/ads) or 'raw' (innerText). Defaults to 'readability'.

Returns: A string containing the extracted page text.

click_element(ref, tab_id=None)

Clicks an element on the page using its accessibility tree reference (e.g., 'e5').

Parameters:

• ref (string, required): The accessibility tree reference of the element to click.
• tab_id (string, optional): The ID of the tab. Defaults to the first tab.

Returns: A string indicating success or failure.

type_text(ref, text, tab_id=None)

Types text into an input field identified by its accessibility tree reference.

Parameters:

• ref (string, required): The accessibility tree reference of the input element.
• text (string, required): The text to type.
• tab_id (string, optional): The ID of the tab. Defaults to the first tab.

Returns: A string indicating success or failure.
