PinchTab Skill

Description

PinchTab is an HTTP server that provides programmatic control over a browser. It supports launching browser instances, navigating to pages, extracting page structure, and interacting with elements like buttons or forms.

When to Use

Use this skill for tasks like:

• Automating browser workflows (e.g., logins, form submissions).
• Extracting data or snapshots from web pages.
• Testing interactive web elements.

Quick Start

Below is a guide to using the PinchTab skill:

1. Launching a Browser Instance

You can launch a new browser instance via the API:

bash

bash scripts/launch_browser.sh

2. Navigating to a URL

Navigate to a URL with the following command:

bash

bash scripts/navigate_to_url.sh https://example.com

3. Extracting Page Snapshot

Get the page structure and save it locally:

bash

bash scripts/get_page_snapshot.sh

4. Clicking an Element

Simulate a button click on a webpage:

bash

bash scripts/click_element.sh "<css_selector>"

5. Taking Screenshots (Base64 Decode + Send to Telegram)

Capture a screenshot, decode the base64, and send to Telegram:

Bash:

bash

export PINCHTAB_TOKEN="your_token"
export TELEGRAM_BOT_TOKEN="your_bot_token"
bash scripts/screenshot_and_send.sh <tab_id> <telegram_chat_id>

Python (more features):

bash

export PINCHTAB_TOKEN="your_token"
python3 scripts/decode_screenshot.py <tab_id> \
  --output /path/to/screenshot.jpg \
  --send-telegram <chat_id> \
  --caption "My screenshot"

Example: Google Homepage

PinchTab successfully navigated to Google and extracted the page structure:

This demonstrates:

• Browser launch and page navigation
• Interactive element extraction (About, Store, Advertising links, etc.)
• Ready for automation (clicking, form filling, data extraction)
