A skill for testing local web apps with Playwright Python scripts, including a helper that starts and stops dev servers.

The SKILL.md tells Claude to write native Python Playwright scripts, with a decision tree for static HTML versus dynamic apps. A bundled scripts/with_server.py manages one or more servers so a script can run against them.

It targets verifying frontend behavior, debugging UI, capturing screenshots and reading browser logs. It ships in the example-skills bundle of the anthropics/skills marketplace.

What the badge means

Source verified means the source URL for this entry responded with HTTP 200 on . That is the whole claim. Nobody has read, scanned or run this code on your behalf, and the badge does not mean Anthropic or anyone else endorses it.
