DO NOT read the source until you try running the script first and find that a customized solution is abslutely necessary. These scripts can be very large and thus pollute your context window. They exist to be called directly as black-box scripts rather than ingested into your context window. To start a server, run --help first, then use the helper: Single server: Multiple servers (e.g., backend + frontend): To create an automation script, include only Playwright logic (servers are managed automatically): Inspect rendered DOM : Identify selectors from inspection results Execute actions using discovered selectors ❌ Don't inspect the DOM before waiting for networkidle on dynamic apps ✅ Do wait for page.wait_for_load_state('networkidle') before inspection - scripts/with_server.py - Manages server lifecycle (supports multiple servers) - Inspect rendered DOM : page . screenshot ( path = '/tmp/inspect.png' , full_page = True ) content = page . content ( ) page . locator ( 'button' ) . all ( ) - Identify selectors from inspection results - Execute actions using discovered selectors - Use bundled scripts as black boxes - To accomplish a task, consider whether one of the scripts available in scripts/ can help. These scripts handle common,...
