EPSL's methods-transparency culture is strictest exactly where the journal is strongest: isotope geochemistry and geochronology. Reviewers expect every headline number to arrive with its complete error budget — internal precision, external reproducibility, standard and blank corrections, and systematic terms like decay-constant uncertainty — and they expect model results to arrive with their resolution limits. Design choices live in epsl-study-design; deposition and supplements in epsl-reporting-and-reproducibility.
Epsl Data Analysis is a community-contributed Claude Code skill in the data-science-research sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/epsl-data-analysis/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when reducing and reporting data for an Earth and Planetary Science Letters (EPSL) manuscript — full analytical-uncertainty budgets for isotope and geochronology data, defensible statistics (MSWD, weighted means, Bayesian age models), and inversion/model diagnostics. It guides reduction and reporting norms; it does not fabricate results.
The Epsl Data Analysis Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 184,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
mkdir -p ~/.claude/skills/epsl-data-analysis curl -L https://claudskills.com/skills/epsl-data-analysis/SKILL.md \ -o ~/.claude/skills/epsl-data-analysis/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/epsl-data-analysis/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/epsl-data-analysis/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\epsl-data-analysis\SKILL.md on Windows. See the full install guide for step-by-step instructions.

The ClaudSkills desktop app installs any skill directly into ~/.claude/skills/ with one click — no terminal required. Pro starts at $9/mo or $149 lifetime.
For the full experience including quality scoring and one-click install features for each skill — upgrade to Pro.
SKILL.md from the source repository to ~/.claude/skills/epsl-data-analysis/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Epsl Data Analysis is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.
