Replication Designer

| 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.
