Do you have experience working with agent development? Have you heard anything about it?

Yes, I am familiar with agent development, particularly with Java Agent — a special component that connects to the JVM and allows modification of class bytecode during loading or execution. It is commonly used for monitoring, profiling, logging, or injecting additional logic without changing the source code.

Example of application: an agent can implement call tracing or collect performance metrics. This is done using the java.lang.instrument API, which implements the premain or agentmain method.

Agents can also be used in system analysis for dynamic behavior modification of applications.
