## What it does and how to use it

A **skill** that teaches Claude Code to do scientific tasks well. It is packaged knowledge the model uses whenever it is relevant.

1. Install the skill (command above).
2. In Claude Code, describe what you need - the skill turns on by itself when the context fits.
3. No commands to memorize: you talk in plain language and the skill does the rest.

## Install (Claude Code)

```bash
mkdir -p .claude/skills/best-practices && curl -fsSL https://doutorai.pt/data/lib/skills__best-practices.md -o .claude/skills/best-practices/SKILL.md
```

Paste this command into the terminal, in your project folder, and the component installs automatically.

# Dask Best Practices

## Performance Optimization Principles

### Start with Simpler Solutions First

Before implementing parallel computing with Dask, explore these alternatives:
- Better algorithms for the specific problem
- Efficient file formats (Parquet, HDF5, Zarr instead of CSV)
- Compiled code via Numba or Cython
- Data sampling for development and testing

These alternatives often provide better returns than distributed systems and should be exhausted before scaling to parallel computing.

### Chunk Size Strategy

**Critical Rule**: Chunks should be small enough that many fit in a wo
