domino-distributed-computing

domino-distributed-computing is a skill for Claude Code, Codex from dominodatalab/domino-claude-plugin. It costs 62 tokens per session (2,124 once invoked), scanned A, original, MIT.

A Domino skill for running computing work across multiple machines with Spark, Ray, Dask, or MPI. These frameworks split large data-processing or machine-learning workloads into parallel tasks.

In plain words
What is it for?
Use it to configure on-demand clusters, process large datasets with Spark, distribute training or tuning with Ray, scale pandas and NumPy with Dask, or run scientific workloads with MPI.
Why use it?
It helps workloads that are too slow or large for one machine run across a cluster. The framework choices clarify which approach fits data processing, distributed training, or parallel Python work.

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

domino-distributed-computing 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 5d 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.

Domino Distributed Computing Skill

Description

This skill helps users work with distributed computing frameworks in Domino - Spark, Ray, and Dask clusters for scaling compute-intensive workloads.

Activation

Activate this skill when users want to:

  • Run Spark, Ray, or Dask clusters in Domino
  • Scale data processing or ML training
  • Configure distributed cluster settings
  • Understand when to use each framework

Supported Frameworks

Framework Best For
Apache Spark Large-scale data processing, SQL, ETL
Ray Distributed ML, hyperparameter tuning, RL
Dask Parallel pandas, NumPy at scale
MPI Scientific computing, HPC workloads

When to Use Each Framework

Spark

  • Processing terabyte-scale data
  • SQL analytics on big data
  • ETL pipelines
  • Structured data processing

Ray

  • Distributed model training
  • Hyperparameter optimization
  • Reinforcement learning
  • Generic Python parallelization

Dask

  • Scaling pandas workflows
  • Parallel NumPy operations
  • Lazy evaluation needed
  • Familiar pandas/NumPy API preferred

Launching On-Demand Clusters

Via Domino UI

  1. Start a workspace or job
  2. Check Attach compute cluster
  3. Select:
    • Cluster Type: Spark, Ray, or Dask
    • Worker Count: Number of workers
    • Hardware Tier: Resources per worker
    • Auto-scaling: Enable/disable
  4. Launch

Via Python SDK

from domino import Domino

domino = Domino("project-owner/project-name")

# Start workspace with Spark cluster
workspace = domino.workspace_start(
    hardware_tier_name="medium",
    cluster_config={
        "clusterType": "Spark",
        "workerCount": 4,
        "workerHardwareTier": "medium",
        "masterHardwareTier": "medium"
    }
)

Apache Spark

Connecting to Spark

from pyspark.sql import SparkSession

# Domino auto-configures Spark
spark = SparkSession.builder.getOrCreate()

# Check configuration
print(f"Spark version: {spark.version}")
print(f"Executors: {spark.sparkContext.defaultParallelism}")

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.

domino-distributed-computing is a skill published in the GitHub repository dominodatalab/domino-claude-plugin (6 stars, last pushed 1mo ago), licensed MIT. It adds 62 tokens to every session and 2,124 once invoked, about $0.0003 per session on Opus 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.
