The Agent Skills Directory

[SAFE]: The skill is a legitimate tool designed for frontend performance auditing. It uses established browser automation practices and follows a professional, measurement-first methodology.\n- [EXTERNAL_DOWNLOADS]: The skill references and uses well-known, industry-standard packages such as @modelcontextprotocol/server-playwright, lighthouse, and webpack-bundle-analyzer. These dependencies are appropriate for the stated purpose of browser automation and performance analysis.\n- [COMMAND_EXECUTION]: Standard shell commands like grep, ls, npm, and npx are used to verify local configurations and analyze build artifacts. These operations are transparent, scoped to the developer's environment, and necessary for the skill's functionality.\n- [DYNAMIC_EXECUTION]: The skill employs browser_evaluate to execute JavaScript in a browser context for the purpose of collecting metrics (e.g., Core Web Vitals, memory usage, and network activity). The executed scripts are predefined templates for data collection and do not process unvalidated external input in a way that poses a security risk.
