agent-browser-core

What This Skill Does

The agent-browser-core skill acts as the primary interface for the OpenClaw agent to interact with the web. Built on a Rust-based CLI with a robust Node.js fallback, it provides a deterministic, machine-readable way to perform web automation. Instead of relying on brittle pixel-based screen scraping, this skill utilizes DOM-based snapshots and unique element references (refs). This approach allows the AI to perceive the browser content as a structured JSON object, making it significantly more reliable for complex workflows like form filling, data extraction, and multi-step navigation. It is designed for production-grade automation where predictability and auditability are critical.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/lion504/agent-browser-core-1-0-1

Ensure that you have a compatible browser runtime installed (such as Chromium or Playwright) as the CLI requires a browser engine to render web pages and generate snapshots.

Use Cases

• Automated Data Research: The agent can navigate to search engines or news portals, extract text data, and compile it into a structured summary.
• Form Submission Automation: Navigate through complex web forms, interact with specific input fields using refs, and submit data securely.
• Regression Testing: Capture before-and-after snapshots of web elements to verify that UI updates have not negatively impacted functionality.
• Account Management: Log into authorized services, perform routine tasks, and handle authentication workflows with session-based persistence.

Example Prompts

1. "Open the browser and go to github.com/openclaw, find the 'Latest Releases' section using the latest snapshot, and list the versions."
2. "Navigate to the registration page for our internal dashboard, fill in the fields with the provided credentials, and confirm the submission succeeds."
3. "Search for the latest documentation on agent-browser core, extract the main installation steps, and format them into a JSON output."

Tips & Limitations

To maximize effectiveness, always trigger a snapshot immediately after a navigation event or DOM change. This ensures the AI is making decisions based on the most current state of the page. Use the --json flag consistently to ensure the agent receives clean input.

Limitations: This skill is not designed for streaming heavy media or executing arbitrary JavaScript on untrusted sites. It is strictly constrained by safe-mode defaults to prevent unauthorized network access or file system modification. Avoid heavy tasks that require long-running browser sessions, as this can exhaust system resources and lead to performance degradation.
