content-extraction

Installation
SKILL.md

This skill extracts ALL content from an existing website and outputs it as structured, reusable data files. It crawls every page, downloads every asset, and produces a complete content inventory.

The user provides: the URL of the site to extract from, and optionally the target format (TypeScript, JSON, Markdown).

What Gets Extracted

For each page on the site:

Content type Output
Text Headings, paragraphs, lists, quotes — preserved with hierarchy
Metadata <title>, <meta description>, OG tags, canonical URL, lang
Images Downloaded to public/images/ with original filenames. Alt text cataloged
Links Internal + external, with anchor text and destination URL
PDFs & assets Downloaded to public/assets/. Filenames and original URLs cataloged
Forms Field names, types, labels, validation rules, action URLs
Navigation Menu structure, link hierarchy, active states
Structured data JSON-LD, microdata, schema.org markup

Extraction Process

Step 1: Discover all pages

Use browser automation (agent-browser or Playwright) to:

1. Start at the site root
2. Extract all internal links from navigation, footer, sitemap.xml
3. Follow every internal link recursively
4. Build a complete page list with URLs
5. Detect and note any client-side routing (SPA)

Step 2: Extract content per page

For each discovered page:

1. Navigate to the page
2. Wait for full load (networkidle)
3. Extract the DOM structure:
   - All headings (h1-h6) with hierarchy
   - All paragraphs and text blocks
   - All lists (ordered/unordered)
   - All images (src, alt, dimensions)
   - All links (href, text, target)
   - All forms (fields, labels, actions)
4. Extract <head> metadata
5. Take a full-page screenshot for reference
6. Save structured data to output files

Step 3: Download assets

1. Download all images to public/images/{page-slug}/
2. Download all PDFs to public/assets/
3. Download favicons, OG images, other static assets
4. Preserve original filenames where possible
5. Note any broken/404 asset URLs

Step 4: Generate output files

content-inventory.md

Human-readable summary of everything extracted:

# Content Inventory — {site-name}

## Pages ({count})

### / (Homepage)
- Title: "Site Name — Tagline"
- Description: "Meta description here"
- H1: "Main Heading"
- Sections: Hero, Features (3), CTA, Testimonials (4)
- Images: 8 (hero.jpg, feature-1.png, ...)
- Links: 12 internal, 3 external
- Forms: none

### /about
...

src/data/*.ts (TypeScript format)

Structured data files ready for import:

// src/data/pages.ts
export interface Page {
  slug: string;
  url: string;
  title: string;
  description: string;
  headings: { level: number; text: string }[];
  sections: Section[];
}

// src/data/navigation.ts
export interface NavItem {
  label: string;
  href: string;
  children?: NavItem[];
}

// src/data/images.ts
export interface ImageAsset {
  originalUrl: string;
  localPath: string;
  alt: string;
  width?: number;
  height?: number;
  page: string;
}

Full-page screenshots of every page for visual reference.

Agent Team Integration

When used as a teammate in website-refactor, this skill runs as the content-extractor agent:

  • Owns: src/data/, scripts/extract/, public/images/, public/assets/, content-inventory.md, screenshots/
  • Outputs: Structured data files that designer and content-verifier teammates consume
  • Signals completion: By marking its task complete and confirming content-inventory.md is written

Standalone Usage

Can be invoked independently for:

  • Content audits: "How much content does this site have?"
  • Migration planning: "Extract everything from the old site before we rebuild"
  • Competitive analysis: "What content does competitor X have?"
  • Archival: "Save a complete copy of this site's content"

Output Formats

The default output is TypeScript (.ts files). Pass format preference as an argument:

  • typescript (default) — src/data/*.ts with interfaces and typed exports
  • json — content/*.json files
  • markdown — content/*.md files with frontmatter

Common Pitfalls

  • SPAs and client-side routing: Some sites don't render content without JavaScript. Always use a real browser (Playwright/agent-browser), not HTTP fetches.
  • Lazy-loaded content: Scroll the full page before extracting to trigger lazy-loaded images and infinite scroll sections.
  • Authentication walls: Some content may be behind login. Note these pages as "requires auth" in the inventory.
  • Rate limiting: Add delays between page fetches to avoid being blocked. 1-2 seconds between requests is safe.
  • Duplicate content: The same content may appear on multiple pages (shared sections, footers). Deduplicate in the data files.
  • Relative URLs: Always resolve to absolute URLs before cataloging or downloading.
