Workflow Routing (SYSTEM PROMPT)
CRITICAL: This workflow implements progressive escalation for URL content retrieval.
When user requests scraping/fetching URL content: Examples: "scrape this URL", "fetch this page", "get content from [URL]", "pull content from this site", "retrieve [URL]", "can't access this site", "this site is blocking me", "use Bright Data to fetch" → READ: ${PAI_DIR}/skills/brightdata/workflows/four-tier-scrape.md → EXECUTE: Four-tier progressive scraping workflow (WebFetch → Curl → Browser Automation → Bright Data MCP)
When to Activate This Skill
Direct Scraping Requests (Categories 1-4)
- "scrape this URL", "scrape [URL]", "scrape this page"
- "fetch this URL", "fetch [URL]", "fetch this page", "fetch content from"
- "pull content from [URL]", "pull this page", "pull from this site"
- "get content from [URL]", "retrieve [URL]", "retrieve this page"
- "do scraping on [URL]", "run scraper on [URL]"
- "basic scrape", "quick scrape", "simple fetch"
- "comprehensive scrape", "deep scrape", "full content extraction"
Access & Bot Detection Issues (Categories 5-7)
- "can't access this site", "site is blocking me", "getting blocked"
- "bot detection", "CAPTCHA", "access denied", "403 error"
- "need to bypass bot detection", "get around blocking"
- "this URL won't load", "can't fetch this page"
- "use Bright Data", "use the scraper", "use advanced scraping"
Result-Oriented Requests (Category 8)
- "get me the content from [URL]"
- "extract text from [URL]"
- "download this page content"
- "convert [URL] to markdown"
- "need the HTML from this site"
Use Case Indicators
- User needs web content for research or analysis

When Each Tier Is Used:
- Tier 1 (WebFetch): Simple sites, public content, no bot detection
- Tier 2 (Curl): Sites with basic user-agent checking, simple bot detection
- Tier 3 (Browser Automation): Sites requiring JavaScript execution, dynamic content loading
- Tier 4 (Bright Data): Sites with CAPTCHA, advanced bot detection, residential proxy requirements
Configuration: No configuration required - all tools are available by default in Claude Code
Examples
Example 1: Simple Public Website
