Firecrawl Scraper Skill

SkillWeb & browsing

This skill uses Firecrawl to turn web pages into clean text your AI can read and work with. Once added, your AI can pull content from single pages or entire sites, including pages that rely on JavaScript or block automated access. It also avoids 10 documented mistakes that commonly break web scraping.

Available today. Use it from your connected AI after setup.

Add the skill, then share a web page address and ask your AI to scrape it or pull out specific details. You can also ask it to re-check a page later to see what has changed.

Then ask your AI: use the Firecrawl Scraper Skill skill

What your AI can do with it

  • Scrape any web page into clean, readable text
  • Crawl entire websites and map their structure
  • Extract structured data from pages
  • Track when a page's content changes
  • Read PDF and DOCX documents
  • Process many pages at once with batch operations

What this skill tells your AI

Trigger Conditions & Endpoint Selection

Choose Firecrawl endpoint based on user intent:

  • scrape: Need to extract content from a single web page (markdown, html, json, screenshot, pdf)
  • crawl: Need to crawl entire website with depth control and path filtering
  • map: Need to quickly get a list of all URLs on a website
  • batch-scrape: Need to scrape multiple URLs in parallel
  • crawl-status: Given crawl job ID, check crawl progress/results (optional --wait)
  • batch-status: Given batch job ID, check batch scrape progress/results (optional --wait)
  • batch-errors: Given batch job ID, retrieve batch scrape errors

Recommended Architecture (Main Skill + Sub-skill)

This skill uses a two-phase architecture:

  1. Main skill (current context): Understand user question → Choose endpoint → Assemble JSON payload
  2. Sub-skill (fork context): Only responsible for HTTP call execution, avoiding conversation history token waste

Execution Method

Use Task tool to invoke firecrawl-fetcher sub-skill, passing command and JSON (stdin):

Task parameters:
- subagent_type: Bash
- description: "Call Firecrawl API"
- prompt: cat <<'JSON' | node scripts/firecrawl-api.cjs <scrape|crawl|map|batch-scrape|crawl-status|batch-status|batch-errors> [--wait]
  { ...payload... }
  JSON

Response Format

All endpoints return JSON with:

  • success: Boolean indicating success
  • data: Extracted content (format depends on endpoint)
  • For crawl: Returns job ID, use crawl-status (or GET /v2/crawl/{id}) to check status
  • For batch-scrape: Returns async job response ({ success, id, url }), use batch-status (or GET /v2/batch/scrape/{id}) to poll status
  • Batch status response includes status, total, completed, creditsUsed, expiresAt, next, data[]
    • next: pagination URL for large/incomplete results (script returns raw response; follow manually if needed)
