These utilities provide deep visibility into how your code behaves while it is actively executing. By monitoring resource consumption, function latency, and memory allocation in real time, they allow you to pinpoint performance bottlenecks that static analysis often misses. When selecting a tool, prioritize those that integrate seamlessly with your existing stack and offer low-overhead capturing to ensure that your measurement process does not degrade final product speed.

AI agent observability. One decorator, that's it.
