firecrawl-scraper（Firecrawl scraper 搜索）

Firecrawl Scraper Skill

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)

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 .claude/skills/firecrawl-scraper/firecrawl-api.cjs <scrape|crawl|map|batch-scrape|crawl-status> [--wait]
  { ...payload... }
  JSON
