Webapp Testing Skill
Anthropic's Webapp Testing skill guides an assistant through local web interactions, screenshots and browser logs using Playwright.
Overview
This skill is for developers with a running web application who need to check buttons, forms or visual regressions. It supplies testing guidance and helper scripts rather than a hosted testing service. A compatible assistant and local browser dependencies are required.

Setup
Enable the skill from Anthropic's official repository using your client's instructions. Prepare Python, Playwright and browser dependencies. Start the app and give the assistant its URL, test steps and expected results using test data.
Risk note
