Selects and executes a credible causal identification strategy - RCT, natural experiment, difference-in-differences, regression discontinuity, instrumental variables, or matching - ranked by assumption strength, with a confounder checklist, falsification tests, and a defensible effect estimate. Use when someone asks "did X actually cause Y", "how do I measure impact without an A/B test", "is this correlation causal", or needs to defend an effect estimate from observational data. Do NOT use for…
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
# Causal Inference A confident effect estimate built on a broken identification strategy is worse than no estimate: it triggers real decisions with fake evidence. This skill forces the choice of design before any regression is run, states the assumptions each design buys, and requires falsification tests before an effect is reported as causal. ## Inputs to collect Gather these before choosing a design. If the user cannot supply one, propose a default and label it a guess. 1. **Treatment**: the intervention, precisely defined (who received it, when, at what intensity). 2. **Outcome**: the measured variable and its timing relative to treatment. 3. **Unit of analysis**: person, account, store, region - and how many units exist on each side. 4. **Assignment mechanism**: how units ended up treated - randomized, threshold rule, policy rollout, self-selection. This single fact determines which designs are available. 5. **Data availability**: pre-treatment periods (how many), untreated comparison units, candidate instruments, covariates. 6. **Decision at stake**: what action the estimate will drive, and how costly a wrong sign or 2x-off magnitude would be. ## Operating procedure …

How to install
mdr add skillmedev/skills/causal-inference@sha256:e93a06a0a67d60b4The line at the top of this page pins the label git:20261005.bea4ea5, 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.
