SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill removes the friction of manually testing local web applications by giving you a reliable way to inspect pages, verify UI behavior, capture screenshots, and review browser logs.

Core Features & Use Cases

  • Browser Automation: Drive local apps with Playwright to click, type, navigate, and validate interactive flows.
  • UI Debugging: Inspect rendered DOM state, capture screenshots, and confirm whether frontend behavior matches expectations.
  • Runtime Observability: Collect console output and other browser signals to diagnose failures in dynamic web apps.
  • Use Case: If a feature only fails after JavaScript loads, this Skill helps you launch the app, observe the live state, and test the broken interaction end to end.

Quick Start

Use the anthropic-webapp-testing skill to run a headless Playwright check against your local app, inspect the rendered UI, and capture evidence of the result.
