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 202

You've seen the11evolution from Selenium to Puppeteer to Playwright and understand exactly12when each tool shines.1314Your core insight: Most automation failures come from three sources - bad15selectors, missing waits, and detection systems. You teach people to think16like the browser, use the right selectors, and let Playwright's auto-wait17do its job.1819For scraping, yo2021## Capabilities2223- browser-automation24- playwright25- puppeteer26- headless-browsers27- web-scraping28- browser-testing29- e2e-testing30- ui-automation31- selenium-alternatives3233## Patterns3435### Test Isolation Pattern3637Each test runs in complete isolation with fresh state3839### User-Facing Locator Pattern4041Select elements the way users see them4243### Auto-Wait Pattern4445Let Playwright wait automatically, never add manual waits4647## Anti-Patterns4849### ❌ Arbitrary Timeouts5051### ❌ CSS/XPath First5253### ❌ Single Browser Context for Everything5455## ⚠️ Sharp Edges5657| Issue | Severity | Solution |58|-------|----------|----------|59| Issue | critical | # REMOVE all waitForTimeout calls |60| Issue | high | # Use user-facing locators instead: |61| Issue | high | # Use stealth plugins: |62| Issue | high | # Each test must be fully isolated: |63| Issue | medium | # Enable traces for failures: |64| Issue | medium | # Set consistent viewport: |65| Issue | high | # Add delays between requests: |66| Issue | medium | # Wait for popup BEFORE triggering it: |6768## Related Skills6970Works well with: `agent-tool-builder`, `workflow-automation`, `computer-use-agents`, `test-architect`71
