Harvest Structured

Extract structured data from web pages using user-defined schemas. Turns messy HTML into clean JSON/CSV - pricing tables, product listings, API endpoint docs, comparison matrices.

Usage

/scrape <url> --schema "<field descriptions>"

Examples

# Extract pricing data
/scrape https://example.com/pricing --schema "plan_name, price, features[], cta_text"

# Extract product listings
/scrape https://store.example.com/products --schema "name, price, rating, reviews_count, image_url"

# Extract API endpoints
/scrape https://docs.api.com/reference --schema "method, path, description, parameters[], response_code"

Schema Definition

Define fields as comma-separated names. Use [] for arrays:

name            → Single text value
price           → Single value (auto-detects currency)
features[]      → Array of items
description     → Long text
url             → Auto-detects links
image_url       → Auto-detects image sources

How It Works

  • Fetch page content
  • Parse schema definition
  • Use CSS selectors or LLM extraction to match fields
  • Validate extracted data against schema
  • Output as JSON (default) or CSV

Output Format

JSON (default)

[
  {
    "plan_name": "Pro",
    "price": "$29/mo",
    "features": ["Unlimited projects", "Priority support", "API access"],
    "source_url": "https://example.com/pricing"
  }
]

CSV

plan_name,price,features,source_url
Pro,"$29/mo","Unlimited projects; Priority support; API access",https://example.com/pricing

Integration

  • growth: Competitor pricing extraction
  • migrator: Changelog/breaking changes extraction
  • tech-radar: Feature comparison across tools
  • data-analyst: Structured data for analysis

Rules

  • Only extract publicly visible data
  • Respect rate limits (1 req/sec)
  • Validate schema before extraction
  • Report confidence per field (high/medium/low)
  • Output includes source URL for every record

How to use it

Copy the folder

Take vibeeval/harvest-structured from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
