Playwright Web Automation

Browser automation via Chromium + playwright-core over CDP. No MCP server needed — scripts run as .mjs files.

Prerequisites

# Install playwright-core (no browser download — uses existing Chromium)
npm install playwright-core

# Verify Chromium exists
which chromium || ls /Applications/Chromium.app/Contents/MacOS/Chromium

Launch Chromium with CDP

# Kill any existing debug instance
pkill -f "remote-debugging-port=9222" 2>/dev/null
