Webapp Testing is an Agent Skill toolkit for interacting with and testing local web applications using Playwright. It supports verifying that frontend functionality works, debugging UI behavior, capturing browser screenshots, and viewing browser logs. Use it when you want Claude to actually drive a running local web app to confirm a change works rather than reasoning about it statically.
