dask

dask is a skill for Claude Code from agentlas-ai/agentlas-desktop. It costs 69 tokens per session (3,872 once invoked), scanned A, a copy of dask, Apache-2.0.

A Python library for processing data in parallel and in pieces, including data that is larger than a computer's memory. It extends familiar pandas and NumPy-style workflows to multiple CPU cores or machines.

In plain words
What is it for?
Use it for out-of-memory data frames, parallel file processing, distributed calculations, and machine-learning data preparation across a cluster.
Why use it?
It helps existing data-processing code handle larger datasets without loading everything into memory at once. It also reduces the need to rewrite pandas or NumPy workflows for cluster computing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dask scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Dask

Overview

Dask is a Python library for parallel and distributed computing that enables three critical capabilities:

  • Larger-than-memory execution on single machines for data exceeding available RAM
  • Parallel processing for improved computational speed across multiple cores
  • Distributed computation supporting terabyte-scale datasets across multiple machines

Dask scales from laptops (processing ~100 GiB) to clusters (processing ~100 TiB) while maintaining familiar Python APIs.

Current upstream: dask 2026.3.0 (PyPI, March 2026). Docs: docs.dask.org. Since 2025.1.0, the expression-based DataFrame API with query planning is the only implementation — do not install dask-expr separately or set dataframe.query-planning: False.

Quick Start

Installation

uv pip install "dask>=2025.1"

For a typical pandas/NumPy workflow with the distributed scheduler and dashboard:

uv pip install "dask[complete]"

Remote object storage (S3, GCS, Azure):

uv pip install s3fs    # s3:// paths
uv pip install gcsfs   # gs:// paths

Requires Python 3.10+ (3.9 support dropped in 2024.12). DataFrame I/O requires PyArrow 16+ (as of dask 2026.1.2).

When to Use This Skill

This skill should be used when:

  • Process datasets that exceed available RAM
  • Scale pandas or NumPy operations to larger datasets
  • Parallelize computations for performance improvements
  • Process multiple files efficiently (CSVs, Parquet, JSON, text logs)
  • Build custom parallel workflows with task dependencies
  • Distribute workloads across multiple cores or machines

Core Capabilities

Dask provides five main components, each suited to different use cases:

1. DataFrames - Parallel Pandas Operations

Purpose: Scale pandas operations to larger datasets through parallel processing.

When to Use:

  • Tabular data exceeds available RAM
  • Need to process multiple CSV/Parquet files together
  • Pandas operations are slow and need parallelization
  • Scaling from pandas prototype to production
