A research-design tool that turns empirical-study notes into a Stata execution plan or, when requested, a starter do-file. Stata is software commonly used for statistical analysis and econometrics.

Use it to plan data preparation, descriptive statistics, correlations, baseline models, mechanism and subgroup tests, robustness checks, and table export in Stata.

It puts data merges, variable construction, regressions, and robustness checks into a clear order. It flags uncertain variable names instead of silently inventing them.

Per session 37 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 695 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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
Fable 5.1	$0.00037	$0.00695
Opus 5	$0.00018	$0.00347
Sonnet 5	$0.00007	$0.00139
Haiku 4.5	$0.00004	$0.00069

Measured 10d ago against content hash b5d25f3869b8, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

stata-plan 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 10d 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.

What it actually says

/stata-plan

把 wiki 中的变量、数据和模型信息转成 Stata 层面的执行顺序。默认生成计划；只有用户传 --write-do 时才创建 .do 骨架。

Workflow

Step 1: Read Design and Data Context

读取：

指定的 wiki/outputs/empirical-design-*.md，或按 topic 匹配最近设计文档
wiki/variables/*.md
wiki/datasets/*.md
wiki/models/*.md
wiki/robustness/*.md
wiki/heterogeneity/*.md
wiki/identification/*.md（设计涉及 DID / PSM / IV / RDD / TWFE 时优先读对应预置策略卡）
tools/stata-templates/*.do（预置模板：twfe / did_staggered / psm / iv_2sls / rdd；--write-do 时以匹配的模板为骨架起点，按设计文档改写变量与参数）
项目中的 .do、.dta、.xlsx、变量字典和 README

Step 2: Produce Stata Execution Plan

输出结构：

# Stata 执行计划

## 1. 输入数据
## 2. 主键与合并顺序
## 3. 样本筛选
## 4. 变量构造
## 5. 缩尾与缺失值处理
## 6. 描述性统计
## 7. 相关性分析
## 8. 基准回归
## 9. 机制检验
## 10. 异质性检验
## 11. 稳健性检验
## 12. 表格导出
## 13. 复核清单

每一步尽量写成 Stata 伪代码或代码块，但不要假造不存在的变量名。变量名不确定时用占位符并标记“需确认”。

Step 3: Optional Do File

只有用户传 --write-do 时，创建：

wiki/outputs/stata-plan-{slug}-{YYYY-MM-DD}.do

默认只写：

wiki/outputs/stata-plan-{slug}-{YYYY-MM-DD}.md

Step 4: Log

python3 tools/research_wiki.py log wiki "stata-plan | <topic> | output: outputs/<file>"

Constraints

不覆盖用户已有 .do 文件。
不假设 Stata 包已经安装；需要 reghdfe、esttab 等时在计划里列出安装命令。
代码骨架必须保留复核点，如样本量检查、merge 结果检查、变量分布检查。
对中文路径和空格路径使用引号。

Changes

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.

stata-plan is a skill published in the GitHub repository Lambenthan/empiricalwiki (82 stars, last pushed 2mo ago), licensed MIT. It adds 37 tokens to every session and 695 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
