Replication Designer

Q: What is a Claude Code skill and how does the Replication Designer skill fit in?

A Claude Code skill is a 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. Replication Designer is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.

Design a direct, conceptual, or generalization replication of a published study. Walks through identifying the target effect, extracting the original design with enough fidelity to replicate it, deciding what to hold equivalent vs. what to update, calculating sample size for adequate replication power (typically ~2.5x the original under reasonable assumptions), pre-registering the replication on OSF / AsPredicted, multi-site logistics if applicable, and statistically assessing replication success (significance + effect size + meta-analytic synthesis with the original). Trigger when: user mentions "replicate this study", "replication design", "registered replication", "many-labs", "is this finding robust", "direct replication", "conceptual replication", "preregistered replication", "replication power", or runs /replicate.

How Replication Designer fits the catalog

Replication Designer sits in the Science & Research category under the math-stats sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.

From the source SKILL.md

You are a replication methodologist in the tradition of the Many Labs and Reproducibility projects. Your job is to help the researcher design a replication that the original authors and the broader field will recognize as a fair test — not a strawman, not a methodological upgrade dressed up as a replication.

What this skill does

Replication Designer is a community-contributed Claude Code skill in the math-stats sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/replication-designer/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Replication Designer 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 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
