该技能是 mastra-ai 项目中的 E2E 测试生成工具，专门用于 packages/playground-ui 和 packages/playground 目录。当你修改 React 组件、重构 UI、添加新 playground 功能或修复影响 Studio UI 的 Bug 时，必须使用此技能。它基于 Playwright 生成端到端测试，重点验证产品行为而不仅仅是 UI 状态变化。这些测试确保 UI 交互、数据流和业务逻辑的正确性，适用于在 Cursor、Claude Code、Codex 等 AI 编码代理环境中使用。该技能通过 SKILL.md 文档定义了触发条件和生成测试的基本原则，帮助开发者自动创建高质量、行为驱动的 E2E 测试套件。
