## Prompt

```text
Help me write a pre-registration for my study before I collect or look at the data.

**Registry or template:** [e.g. "OSF standard", "AsPredicted", "clinical trial registry", or "not sure"]
**Research question and hypotheses:** [DETAILS]
**Design:** [experimental, observational, conditions, within/between]
**Participants or data source:** [population, recruitment, inclusion/exclusion]
**Planned sample size and justification:** [NUMBER and basis, or "need help"]
**Measures and variables:** [IVs, DVs, covariates, how each is measured or scored]
**Planned analyses:** [models or tests I intend to use]

Draft these sections: hypotheses (each directional and falsifiable), design, sampling plan and stopping rule, variables with operational definitions, primary vs. secondary analyses, inference criteria (alpha, corrections for multiple comparisons), data exclusion rules, handling of missing data and outliers, and what counts as exploratory.

Then run a check: list every analytic decision still left open (researcher degrees of freedom), and ask me to decide each one now.

Return the pre-registration text with headings, plus a list of open decisions marked [DECIDE]. Do not invent measures, sample sizes, or prior effect sizes; mark gaps [ADD].
