Distributed computing for larger-than-RAM pandas/NumPy workflows. Use when you need to scale existing pandas/NumPy code beyond memory or across clusters. Best for parallel file processing, distributed ML, integration with existing pandas code. For out-of-core analytics on single machine use vaex; for in-memory speed use polars.

Excellent skill with comprehensive coverage of Dask distributed computing. The Description is extremely clear about when to use Dask vs alternatives (vaex, polars). SKILL.md provides outstanding structure with a decision-tree approach to choosing components (DataFrames/Arrays/Bags/Futures/Schedulers), complete with quick examples and clear references to detailed documentation files. Task knowledge is extensive, including common patterns, performance optimization rules, debugging workflows, and anti-patterns. The skill meaningfully reduces token costs for complex distributed computing tasks that would otherwise require extensive documentation lookup and trial-and-error. Structure is exemplary: concise overview in SKILL.md with systematic references to detailed guides. Novelty is strong since configuring Dask properly (scheduler selection, chunking strategies, avoiding common pitfalls) requires significant expertise that this skill encapsulates effectively.
