name: brightdata description: | Progressive four-tier URL content scraping with automatic fallback strategy.

USE WHEN user says "scrape this URL", "fetch this page", "get content from", "can't access this site", "use Bright Data", "pull content from URL", or needs to retrieve web content that may have bot detection or access restrictions.

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)
