HTML to Image Skill (via agent-browser)

This skill utilizes OpenClaw's agent-browser composition to render a URL, local HTML file, or raw HTML string into an image. It executes a lightweight Bash script wrapper.

Usage Guide

When using this skill to generate an image, provide the source_type and source_content.

• source_type: The content format (url, file, or code).
• source_content: The target URL, absolute file path, or HTML code block.
• format: The desired image format (png, jpeg, or webp). Default is png.
• width: The width of the browser viewport. Default is 1200px.
• full_page: Set to true to take a full page screenshot instead of just the viewport.
