fast-browser-use

What This Skill Does

The fast-browser-use skill, developed by dalessandro07, provides a high-performance, Rust-based engine for browser automation. By leveraging direct Chrome DevTools Protocol (CDP) communication, it avoids the heavy overhead typical of language-heavy automation frameworks. It is designed to be the "go-to" tool for tasks requiring high-speed DOM extraction, complex session persistence, and stealth-oriented navigation. Its core strength lies in its ability to interact with modern web applications while maintaining a lightweight footprint, making it ideal for integration within AI agent workflows that require real-time web context.

Installation

To integrate this skill into your environment, use the OpenClaw command-line interface. Execute the following command in your terminal:

clawhub install openclaw/skills/skills/dalessandro07/fast-browser-use-src

Ensure that you have a compatible version of Chromium or Google Chrome installed on your host system, as the binary relies on an existing browser installation to execute the automation commands via CDP.

Use Cases

This skill is built for professional-grade web interaction. Use it to:

• Stealth Scaping: Use the human emulation feature to navigate sites with strict anti-bot measures by simulating mouse jitter and natural timing.
• Session Management: Authenticate into private portals once and reuse session cookies for long-term data collection tasks without repeating manual logins.
• Infinite Scroll Harvesting: Automatically scroll through social feeds or search results to aggregate data from pages that load content dynamically.
• Site Analysis: Parse sitemaps and structural layouts to map out a website's information architecture for SEO or research purposes.

Example Prompts

1. "Navigate to the Reddit feed for /r/technology, scroll down 5 times to load more content, and extract all article titles into a JSON file."
2. "Log into my account at this URL [link] using my existing auth.json file, then take a full-page screenshot of the dashboard and save it as dashboard_capture.png."
3. "Analyze the structural layout of the documentation page at [url] and identify all main headings and navigation links, saving the structure to a file."

Tips & Limitations

• Tip: Always use the --human-emulation flag when interacting with sites that rely on Cloudflare or other bot-detection services, as standard headless requests are easily flagged.
• Tip: For large-scale data extraction, use the --output flag frequently to ensure your data is persisted even if a session is interrupted.
• Limitation: The binary is optimized for speed; however, extremely heavy dynamic pages (like complex WebGL-based apps) may occasionally require a slight increase in --delay to allow the DOM to settle before extraction.
