LambdaTest/agent-skills ? reverse-engineered prompt

Build me a repo of ready to install AI skills for TestMu AI that helps coding assistants write good test automation for common frameworks like Selenium, Playwright, Cypress, Appium, pytest, JUnit, and the other popular ones in this space.

I want it to be easy for someone to clone, add the skills they need, and then ask their assistant to generate tests, update existing tests, and run them on the TestMu AI cloud. Include clear setup steps, environment variables for the TestMu AI username and access key, and simple examples for using the skills with a few different frameworks. It should also support local app testing through tunnel setup, and have a way to list all available skills and install just one skill at a time.

Please make the README friendly and beginner oriented, and add whatever files are needed so the whole thing feels polished and ready to use. If you need to check current docs or best practices, look them up online.
