playwright-dev

The 'playwright-dev' skill is designed to guide developers through the process of extending and maintaining the Playwright framework. It addresses the challenges of modifying a complex testing framework by providing structured guidance on adding new APIs, integrating tools, managing dependencies, and updating browser versions. By consolidating this information, the skill helps developers efficiently navigate the Playwright monorepo, understand the architecture, and implement changes consistently while adhering to project conventions.

Key features of the skill include detailed guides on library architecture, API development, MCP tools, CLI commands, and vendor dependencies. It also covers practical tasks such as updating the WebKit Safari version, bisecting published versions to reproduce regressions, and working with the Playwright dashboard. Each guide provides step-by-step instructions, best practices, and references to relevant documentation files, ensuring developers can implement features and fixes reliably across client, server, and protocol layers.

This skill is primarily aimed at software engineers and contributors working with Playwright who need to extend its functionality or maintain its codebase. Use cases include developing new APIs, adding CLI commands, managing external dependencies, testing across browser versions, and debugging regressions. It is especially valuable for teams working in monorepo environments, where understanding the structure and interdependencies of the framework is crucial for efficient development and consistent code quality.
