Which profiling tools does this Claude Code skill support?

The skill provides guidance and implementation patterns for PyInstrument (statistical profiling), cProfile (deterministic profiling), and memray (memory profiling).

How does it help with Python memory management?

It offers strategies for using generators to handle large datasets, deque for fast queue operations, and tools to generate flamegraphs for visualizing memory consumption.

Can this skill help with automated performance testing?

Yes, it includes specific patterns for using pytest-benchmark to establish performance baselines and detect speed regressions during CI/CD.

Does it provide specific code-level optimization tips?

Absolutely; it includes best practices for O(1) lookups using sets/dicts, efficient string building techniques, and using lru_cache for expensive computations.
