When should I use this skill instead of just rewriting code?

You should use this skill whenever your application fails to meet production performance requirements, as it helps identify if the issue is algorithmic, I/O-bound, or CPU-bound.

How does this skill identify slow Python code?

It provides a structured workflow starting with cProfile and line-by-line profiling to identify exact bottlenecks before suggesting algorithmic or architectural changes.

Does it support high-performance libraries like NumPy?

Yes, the skill offers specific guidance on vectorization with NumPy, JIT compilation with Numba, and using Cython for performance-critical hot paths.

Can this skill help with memory leaks?

Yes, it includes specialized patterns for memory profiling, checking for high consumption, and using generators to handle large datasets without exhausting RAM.
