Browser Automation

Browser automation powers web testing, scraping, and AI agent interactions.
The difference between a flaky script and a reliable system comes down to
understanding selectors, waiting strategies, and anti-detection patterns.

This skill covers Playwright (recommended) and Puppeteer, with patterns for
testing, scraping, and agentic browser control. Key insight: Playwright won
the framework war. Unless you need Puppeteer's stealth ecosystem or are
Chrome-only, Playwright is the better choice in 2025.

Critical distinction: Testing automation (predictable apps you control) vs
scraping/agent automation (unpredictable sites that fight back). Different
problems, different solutions.
