What is preregistration-guide?

A guide to preregistration, which records a research study’s hypotheses, methods, and analysis plan before data collection or analysis. It also covers registered reports and open science practices.

Use it to write preregistrations for OSF, AsPredicted, or similar services, and to plan studies transparently before collecting or analysing data.

It helps separate planned hypothesis tests from later exploration and reduces selective reporting or changing the analysis after seeing the results.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked

Security

Grade A, and why

preregistration-guide scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Preregistration Guide

Preregistration is the practice of documenting your research plan before conducting a study — specifying hypotheses, methods, and analyses in advance. It separates confirmatory research (testing hypotheses) from exploratory research (generating hypotheses), reducing the risk of questionable research practices such as p-hacking, HARKing (hypothesising after results are known), and selective reporting.

What Is Preregistration?

Definition: A time-stamped, immutable record of your research intentions, created before you collect or analyse data.

Purpose:

Distinguish confirmatory from exploratory research
Reduce researcher degrees of freedom (flexibility in analysis choices)
Prevent selective reporting of significant results
Increase transparency and credibility

Benefits:

Higher credibility for published findings
Clearer thinking during study design
Protection against reviewer requests for post-hoc analyses
Evidence of research integrity for funders and institutions

When to Preregister

Stage	Preregistration Type	Description
Before data collection	Full preregistration	Hypotheses, design, sample size, analysis plan all specified in advance
Before data analysis	Secondary data analysis / Registered Report	Hypotheses and analysis plan specified before analysing existing data
After data collection, before analysis	Partial preregistration	Analysis plan specified; hypotheses may be informed by data patterns

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
