What it does
Aer Identification is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Use when selecting, implementing, or stress-testing the causal identification strategy for an empirical economics manuscript — difference-in-differences (including staggered designs), instrumental variables (including weak-IV-robust inference), regression discontinuity, synthetic control, or shift-share / Bartik. Apply before writing the introduction or results.
Its SKILL.md is about 3k 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/estimator-playbook.md`).
It sits in Research & Science, covering Econometrics and empirical research. 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
- Instrumental variables (including weak-IV-robust inference)
- Regression discontinuity
- Synthetic control
- Shift-share / Bartik
Example prompts
- “/aer-identification”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Goodman-Bacon decomposition to show the share of weight from "forbidden" comparisons under TWFE
- Event-study plot with the imputation or Callaway-Sant'Anna estimator
- Pre-trends test reported as the joint test, not just the visual
- Heterogeneity by treatment cohort
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
No scripts in the folder and no shell commands in SKILL.md.
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 Identification loads about 3k tokens when it runs, and up to ~7.3k if it reads all its reference files. Until then it costs about 96 tokens; SKILL.md has 1,261 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 1,261 words (~2,960 tokens).
“In AER-track empirical economics, identification is the paper. This skill routes among canonical designs, modern defaults, and referee-facing diagnostics.”

Aer Identification is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Use when selecting, implementing, or stress-testing the causal identification strategy for an empirical economics manuscript — difference-in-differences (including staggered designs), instrumental variables (including weak-IV-robust inference), regression discontinuity, synthetic control, or shift-share / Bartik.
When should I use Aer Identification?
Aer Identification fits situations like: instrumental variables (including weak-IV-robust inference); regression discontinuity; synthetic control; shift-share / Bartik.
How do I install Aer Identification in Claude Code?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill aer-identification -a claude-code`. Or copy the skill folder (skills/50-brycewang-aer-skills/skills/aer-identification in brycewang-stanford/Auto-Empirical-Research-Skills) into .claude/skills/aer-identification in your project. Claude Code loads it when a task matches its description.
How do I install Aer Identification in Codex?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill aer-identification -a codex`. Or copy the skill folder (skills/50-brycewang-aer-skills/skills/aer-identification in brycewang-stanford/Auto-Empirical-Research-Skills) into .agents/skills/aer-identification in your project. Codex loads it when a task matches its description.
Can I use Aer Identification 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-identification -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-identification, .gemini/skills/aer-identification, .github/skills/aer-identification and .opencode/skills/aer-identification in your project.
What does Aer Identification need to run?
SKILL.md names no scripts, command-line tools or credentials: Aer Identification is instructions for the agent only.
Does Aer Identification 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 Identification 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 Identification use?
Aer Identification 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 Identification use?
About 3k tokens (SKILL.md is roughly 12k 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 4.3k tokens, read only when the agent opens those files.
What are the alternatives to Aer Identification?
Skills that share tags, products or a category with Aer Identification: Stata (dylantmoore/stata-skill, 291 stars), Stata C Plugins (dylantmoore/stata-skill, 291 stars), Example Datasets (pymc-labs/CausalPy, 1.2k stars) and Stata Audit (SepineTam/mcp-for-stata, 264 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Aer Identification?
brycewang-stanford (a GitHub user) maintains it in brycewang-stanford/Auto-Empirical-Research-Skills, which has 4,556 GitHub stars. The repository holds 383 skills in this directory. The repository was last updated on October 5, 2026.
