Can it extract structured data from APIs?

Yes, Strategy 4 allows the skill to intercept network requests (like GraphQL or REST calls) to read JSON payloads directly, providing cleaner data than DOM scraping.

How does Web Extractor handle virtual scrolling?

The skill identifies the specific scroll container, systematically moves through it in viewport-sized increments, and merges the captured text while deduplicating overlapping sections.

What should I do if WebFetch returns a 403 error?

Trigger the Web Extractor skill; it uses browser-based automation to render the page fully, which often bypasses basic bot detection and permission errors.

Can this skill scrape text from Unity or WebGL games?

Yes, it uses a specialized strategy involving mouse wheel scrolling and screenshot transcription to extract content that is rendered purely as pixels inside a canvas element.

Does it work on pages requiring authentication?

Yes, as long as you have the site open in a connected Chrome instance where you are authenticated, the skill can read the rendered DOM content directly.

Web Scraping & Data Collection

Extracts complete text content from complex, dynamically-loaded, and canvas-rendered web pages where standard tools fail.

The Web Extractor skill enables Claude to scrape and read content from modern web environments that standard HTTP fetches cannot access. It specializes in navigating Single Page Applications (SPAs), virtual scrolling documents, and hardware-accelerated canvas elements like Unity WebGL. By employing sophisticated strategies—including DOM analysis, scroll-and-capture loops, API interception, and visual transcription from screenshots—it ensures comprehensive data extraction from platforms like Google Docs, Notion, and Confluence, even when content is protected by authentication or lazy loading.

Key Features
