Customization

Before executing, check for user customizations at: ~/.claude/PAI/USER/SKILLCUSTOMIZATIONS/BrightData/

If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.

🚨 MANDATORY: Voice Notification (REQUIRED BEFORE ANY ACTION)

You MUST send this notification BEFORE doing anything else when this skill is invoked.

1. Send voice notification: curl -s -X POST http://localhost:8888/notify \ -H "Content-Type: application/json" \ -d '{"message": "Running the WORKFLOWNAME workflow in the BrightData skill to ACTION"}' \ > /dev/null 2>&1 &
2. Output text notification: Running the **WorkflowName** workflow in the **BrightData** skill to ACTION...

This is not optional. Execute this curl command immediately upon skill invocation.

Workflow Routing

When executing a workflow, output this notification directly:

Running the **WorkflowName** workflow in the **Brightdata** skill to ACTION...

Route to the appropriate workflow based on the request.

When user requests scraping/fetching a single URL: 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: Workflows/FourTierScrape.md → EXECUTE: Four-tier progressive scraping workflow (WebFetch → Curl → Browser Automation → Bright Data MCP)

When user requests crawling multiple pages from a site: Examples: "crawl this site", "crawl all pages under /docs", "spider this domain", "map this website", "get all pages from", "crawl [URL]", "scrape the whole site", "extract all pages" → READ: Workflows/Crawl.md → EXECUTE: Crawl workflow (Light Crawl for <50 pages, Full Crawl via Bright Data Crawl API for larger sites)

When to Activate This Skill

Direct Scraping Requests (Categories 1-4)

• "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"

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"

Crawling Requests (Categories 9-11)

• "crawl this site", "crawl [URL]", "spider this domain"
• "map this website", "get all pages from [URL]", "scrape the whole site"
• "crawl all pages under /docs", "extract all pages from", "site crawl"
• "get every page on this site", "full site extraction"
• "crawl depth 3", "crawl up to 50 pages"

Use Case Indicators

• User needs web content for research or analysis
• Standard methods (WebFetch) are failing
• Site has bot detection or rate limiting
• Need reliable content extraction
• Converting web pages to structured format (markdown)
• User needs multiple pages from a site, not just one
• User wants to map a site's structure or extract a section

Core Capabilities

Progressive Escalation Strategy:

1. Tier 1: WebFetch - Fast, simple, built-in Claude Code tool
2. Tier 2: Customized Curl - Chrome-like browser headers to bypass basic bot detection
3. Tier 3: Browser Automation - Full browser automation using Playwright for JavaScript-heavy sites
4. Tier 4: Bright Data MCP - Professional scraping service that handles CAPTCHA and advanced bot detection

Key Features:

• Automatic fallback between tiers
• Preserves content in markdown format
• Handles bot detection and CAPTCHA
• Works with any URL
• Efficient resource usage (only escalates when needed)

Workflow Overview

FourTierScrape.md - Complete URL content scraping with four-tier fallback strategy

• When to use: Any single URL content retrieval request
• Process: Start with WebFetch → If fails, use curl with Chrome headers → If fails, use Browser Automation → If fails, use Bright Data MCP
• Output: URL content in markdown format

Crawl.md - Multi-page crawling with link discovery and site mapping

• When to use: Crawling multiple pages from a site, mapping site structure, extracting a section
• Process: Light Crawl (MCP scrape_batch + link extraction loop, up to 50 pages) or Full Crawl (Bright Data Crawl API for entire sites)
• Output: Site map + page contents in markdown, with crawl stats and cost summary

Extended Context

Integration Points:

• WebFetch Tool - Built-in Claude Code tool for basic URL fetching
• Bash Tool - For executing curl commands with custom headers
• Browser Automation - Playwright-based browser automation for JavaScript rendering
• Bright Data MCP - mcp__Brightdata__scrape_as_markdown and scrape_batch for advanced scraping
• Bright Data Crawl API - HTTP POST to api.brightdata.com/datasets/v3/trigger for full-site crawls

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
