dask

dask is a skill for Claude Code from K-Dense-AI/scientific-agent-skills. It costs 67 tokens per session (4,075 once invoked), scanned A, original, MIT.

A Python tool for processing pandas and NumPy data in parallel, including datasets too large to fit in computer memory or spread across several machines.

In plain words
What is it for?
Use it for parallel file processing, larger-than-memory data analysis, and distributed machine-learning workflows while working with familiar pandas and NumPy code.
Why use it?
It lets existing data-processing code handle larger datasets without loading everything into memory at once. It can also divide work across processor cores or a computing cluster.

About the project

Scientific Agent Skills is a collection of reusable procedures that give AI agents capabilities for scientific research across areas such as biology, chemistry, medicine, and drug discovery. It is used by researchers and by people building AI scientist workflows with compatible coding agents. The catalogue contains many of the project's skills and supporting instructions.

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 14d 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

Capacity depends on partition sizes, intermediate data, concurrency, storage, and available memory.

Reviewed release: dask/distributed 2026.8.0 (September 30, 2026 review). 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[array,dataframe]==2026.8.0"

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

uv pip install "dask[complete]==2026.8.0"

Remote object storage (requires provider credentials for private data):

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

Requires Python 3.10+, pandas 2+, PyArrow 16+. Zarr, HDF5, SciPy, Xarray, Dask-ML, and cluster deployment packages are separate optional dependencies. See review and validation for tested versions, source links, and limits. File paths and undefined application functions below are illustrative. Put process scheduler/Client() execution in a main() guarded by if __name__ == "__main__": in scripts; close clients and clusters afterward.

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

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dask is a skill published in the GitHub repository K-Dense-AI/scientific-agent-skills (50,453 stars, last pushed today), licensed MIT. It adds 67 tokens to every session and 4,075 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
