# Verify local web apps with Playwright scripts and managed dev servers

Use Anthropic's webapp-testing skill to spin up one or more local servers, wait for them to become reachable, and run native Playwright checks against the rendered app. It is for agent-led verification and UI debugging of local web apps, not for listing Playwright as a generic browser framework.

## Prerequisites

Python, Playwright, and one or more local web application server commands

## Installation

Choose whichever fits your setup:

1. Copy this skill folder into your local skills directory.
2. Clone the repo and symlink or copy the skill into your agent workspace.
3. Add the repo as a git submodule if you manage shared skills centrally.
4. Install it through your internal provisioning or packaging workflow.
5. Download the folder directly from GitHub and place it in your skills collection.

Install command or upstream instructions:

```
Clone or install anthropics/skills, run python skills/webapp-testing/scripts/with_server.py --help, then wrap your native Python Playwright script with the helper so the required local server processes are started and awaited automatically.
```
