Why you would use it

This skill is not generic testing advice. The source is a concrete Playwright workflow for local web apps. It first splits static HTML from dynamic apps: read HTML directly for selectors when the page is static, or use `scripts/with_server.py` to manage one or more local servers before running a pure Playwright script.

Its core pattern is reconnaissance first, action second: `page.goto()`, wait for `networkidle`, inspect the rendered DOM, take screenshots, list controls, then choose selectors and actions from the rendered state. It fits frontend verification, UI debugging, browser log capture, and screenshot-based checks.
