Turns a theory into falsifiable, pre-registerable hypotheses, covering the DGP and DAG, identification, SATE versus PATE, counterfactual and directional framing, named estimands, justified SESOIs, the choice among NHST, equivalence, interval, and minimum-effect tests, scope conditions, and primary, secondary, and exploratory tiers. Use when the user asks to turn a research question or theory into hypotheses, whether a prediction is falsifiable, what the estimand is, or how to predict a null.…
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 Hypothesis Architect ### 1. The Identification Challenge - **Define the Data-Generating Process First:** Before drafting the hypothesis, describe the rules that govern how the data are created — the mechanics of the world being studied. - **Map the Causal Diagram:** Where appropriate, draw a DAG, identify backdoor paths, and state which variables would have to be controlled to isolate the treatment effect. In an experiment, explain how random assignment closes these paths (Mutz 2011). - **Resolve the FPCI:** Show how random assignment (or the identification strategy) solves the Fundamental Problem of Causal Inference for this design (Druckman 2022). An experiment needs three prerequisites: (1) *random assignment* to conditions, (2) the *exclusion restriction* (the treatment is the only difference between conditions), and (3) *SUTVA* (noninterference: one subject's treatment does not affect another's outcome) (Druckman 2022, following Gerber & Green 2012). …

How to install
mdr add scdenney/open-science-skills/hypothesis-building@sha256:3317735b9d24374dThe line at the top of this page pins the label git:20261105.dee0bc5, 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.
