I built an agent and tested it without writing a single line of code. Here is how to create a digital twin of your agent, mock every tool it touches, and simulate every function it runs without affecting production. I'm using Claude Code here. Probably the closest thing to magic you'll see this month. This will test and discover problems with your agent that you didn't even know were possible. It will then tell you how to fix everything it finds.
