What it does
Aer Preregistration is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Use when the project collects primary data or runs a field, lab, or survey experiment, before the intervention begins — write the pre-analysis plan, size the sample from a power calculation, and register with the AEA RCT Registry. Apply after the design is chosen in aer-identification and before any outcome data are seen.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/pap-template.md`).
The repository describes itself as: 🔬 A curated collection of 23,000+ agent skills for empirical research across 8 social science disciplines. | 精选 23,000+ AI Agent 技能库，覆盖8大社会科学学科的实证研究。CoPaper.AI…
When your agent uses it
- The project collects primary data
- Survey experiment
- Before the intervention begins — write the pre-analysis plan
- Size the sample from a power calculation
Example prompts
- “/aer-preregistration”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Hypotheses — each stated as a signed, testable prediction, not a topic
- Primary outcomes — a short list (ideally 1-3). Everything else is
- Estimating equation — the exact regression, fixed effects, covariates,
- Sample and inclusion rules — who is in the analysis and how attrition is
- Multiple-testing correction — the family and the method (e.g. Romano-Wolf,
- Heterogeneity — the subgroups you will test, fixed in advance; all others
- Power — the MDE and the assumptions behind it (below).
What it can do on your machine
Read from SKILL.md and the folder at commit 9fa87d8. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
go
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Aer Preregistration loads about 1.9k tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 86 tokens; SKILL.md has 855 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 855 words (~1,882 tokens).
“For experimental and prospective-data AER-track work, credibility is bought before the data exist. This skill writes the pre-analysis plan (PAP), sizes the sample from a power calculation, and registers the study. Its job is to make the eventual results un-p-hackable…”

When should I use Aer Preregistration?
Aer Preregistration fits situations like: the project collects primary data; survey experiment; before the intervention begins — write the pre-analysis plan; size the sample from a power calculation.
How do I install Aer Preregistration in Claude Code?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill aer-preregistration -a claude-code`. Or copy the skill folder (skills/50-brycewang-aer-skills/skills/aer-preregistration in brycewang-stanford/Auto-Empirical-Research-Skills) into .claude/skills/aer-preregistration in your project. Claude Code loads it when a task matches its description.
How do I install Aer Preregistration in Codex?

Can I use Aer Preregistration in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill aer-preregistration -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/aer-preregistration, .gemini/skills/aer-preregistration, .github/skills/aer-preregistration and .opencode/skills/aer-preregistration in your project.
What does Aer Preregistration need to run?
Going by SKILL.md and its folder, Aer Preregistration needs the command-line tools its instructions call (go).
Does Aer Preregistration access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Aer Preregistration safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Aer Preregistration use?
Aer Preregistration has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Aer Preregistration use?
About 1.9k tokens (SKILL.md is roughly 7.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.4k tokens, read only when the agent opens those files.
