What it does and how to use it

A skill that teaches Claude Code to do general 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)

mkdir -p .claude/skills/wshobson-agents__spark-training-gotchas && curl -fsSL https://doutorai.pt/data/lib/skills__wshobson-agents__spark-training-gotchas.md -o .claude/skills/wshobson-agents__spark-training-gotchas/SKILL.md

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

# Spark Training Gotchas

DGX Spark's GB10 chip (Grace Blackwell, SM121, 128GB unified
memory, aarch64) has ten recurring failure modes across
launch, memory, thermals, bandwidth, and precision. Each is
named G1–G10 so it can be checked by number - the numbering
is load-bearing for tooling that runs these checks
