robustness-checks

robustness-checks is a skill for Claude Code, Codex from wentorai/research-plugins. It costs 17 tokens per session (1,776 once invoked), scanned A, original, MIT.

A Stata workflow for robustness checks, which test whether a statistical result stays similar when additional possible confounding factors are included. It adds groups of controls step by step and compares the models.

In plain words
What is it for?
Use it to build sequential regression models, add blocks of contextual, health, psychological, or behavioural factors, calculate treatment effects, and compare estimates and standard errors.
Why use it?
It makes it easier to see whether an estimated relationship depends heavily on a particular set of control variables.

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.

Security

Grade A, and why

robustness-checks 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 6d 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.

Robustness Checks

A skill for conducting sequential robustness checks in Stata, systematically adding blocks of potential confounders to assess estimate stability.

Quick Start

* Base model
svy: regress outcome controls treatment
estimates store m1

* Add confounder block
svy: regress outcome controls treatment confounder1 confounder2
estimates store m2

* Compare
esttab m1 m2, se star(+ 0.1 * 0.05 ** 0.01)

Key Patterns

1. Sequential Model Building

* Define base controls
local control_var i.batch age i.race i.gender i.education
estimates clear

* Model 1: Base model
svy: regress outcome `control_var' treatment
margins, dydx(treatment) post
estimates store m1

* Model 2: Add contextual factors
svy: regress outcome `control_var' treatment covid health_insurance
margins, dydx(treatment) post
estimates store m2

* Model 3: Add health factors
svy: regress outcome `control_var' treatment cci_charlson any_encounter
margins, dydx(treatment) post
estimates store m3

* Model 4: Add psychological factors
svy: regress outcome `control_var' treatment depression anxiety
margins, dydx(treatment) post
estimates store m4

* Model 5: Add behavioral factors
svy: regress outcome `control_var' treatment i.smoke_status bmi
margins, dydx(treatment) post
estimates store m5

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.

robustness-checks is a skill published in the GitHub repository wentorai/research-plugins (287 stars, last pushed 2mo ago), licensed MIT. It adds 17 tokens to every session and 1,776 once invoked, about $0.0001 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.
