Analysis Spec Builder is a production-ready Claude Code skill (quality score 70/100) in the physics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/analysis-spec-builder/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user asks to create or update an analysis spec, requests plots/histograms for a dataset, or describes a quick analysis task that should be formalized into a specification document.
The Analysis Spec Builder skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It is part of the open ClaudSkills registry, a community-curated catalog of 15,000+ capabilities you can install for Claude Code — the Claude CLI agent.
mkdir -p ~/.claude/skills/analysis-spec-builder curl -L https://claudskills.com/skills/analysis-spec-builder/SKILL.md \ -o ~/.claude/skills/analysis-spec-builder/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/analysis-spec-builder/. Claude Code auto-discovers it on next session.
