Description

Uses Playwright MCP to launch a browser, navigate to your app (localhost or remote URL), and systematically test functionality and mobile responsiveness. Takes snapshots to understand page structure, interacts with elements (clicks, types, selects), validates expected behavior, resizes the browser to mobile/tablet viewports to verify responsive design, and generates a test report with pass/fail results and screenshots of failures.

Execution

This skill runs using Claude Code with subscription plan. Requires the Playwright MCP server to be configured and available. All browser interactions use Playwright MCP tools (browser_navigate, browser_snapshot, browser_click, browser_type, etc.).
