How does this skill help with Python 3.13 features?

It provides specific instructions on enabling and benchmarking the experimental JIT compiler and free-threaded (no-GIL) mode to assess real-world performance gains and compatibility.

Can I use this for profiling production services?

Yes, the skill includes patterns for using py-spy to attach to running processes by PID, allowing you to profile live workers without modifying or restarting the code.

Does it cover memory leak detection?

It focuses on memory optimization techniques and utilizes memory_profiler for line-by-line analysis to identify high-usage areas and inefficient data structures.

Is this skill compatible with AsyncIO applications?

Absolutely. It identifies common async anti-patterns, such as blocking the event loop with synchronous calls, and provides high-performance concurrent patterns using asyncio.gather and to_thread.
