A tester agent is like a dedicated detective for your code. It checks every part of your software to find bugs and problems before users do. Testing means running many checks to make sure everything works as expected.
This agent handles different kinds of tests. It can test small pieces of code with unit tests. It checks how parts work together with integration tests. It also runs full user flows with end-to-end tests. The agent even looks for slow performance and security holes.
Using this skill helps you catch errors early. Your code becomes more reliable and safer. Developers can focus on building new features while the tester agent keeps quality high.
