Causal inference toolkit for when experiments are not possible: estimate treatment effects from observational data with assumption checks and mandatory caveats. Invoke as /causal. Trigger on "causal", "caused", "impact of", "effect of", "attribution", "counterfactual", "difference-in-differences", "DiD", "propensity matching", "pre-post". If randomization IS possible, route to /experiment design instead.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill: /causal — OpenCausalInf Causal Inference Toolkit ## Purpose Multi-mode skill for causal inference when experiments aren't possible. Helps users estimate treatment effects from observational data with explicit assumption checking, sensitivity analysis, and mandatory caveats. Uses coded helpers from `helpers/stats/experiment_stats/causal/`. ## When to Use Invoke as `/causal [mode]` or trigger on causal inference intents: - "Did this feature actually cause the improvement?" - "We can't run an experiment, but..." - "Was this change responsible for the metric movement?" - "Can we measure the impact retroactively?" ## Modes ### `/causal select` **Purpose:** Walk the method selection decision tree and recommend a causal method. **Agent:** `agents/causal/causal-method-selector.md` **Flow:** 1. Ask 4-6 diagnostic questions: - Can you randomize? → Route to `/experiment design` - Do you have a comparison group? - Do you have pre-treatment data? - Are there observable confounders you can measure? - How many time periods do you have? 2. Recommend: Pre-Post, DiD, PSM, Regression Adjustment, or "not feasible" …

How to install
mdr add ai-analyst-lab/ai-analyst/causal@sha256:e7ec17d3f7b0b236The line at the top of this page pins the label git:20260828.01c26bc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
