Use when a product decision depends on an uncertain claim and needs a bounded, falsifiable check.
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
# Hypothesis Validation Use this method when a product or research decision depends on an uncertain, observable claim. This task-skill inherits the caller's model to follow Datarim's vendor-default assignment policy for structured research and content work. It helps a researcher state what would change their mind and choose a proportionate way to learn. It does not run experiments, grant permission, establish market demand, or make a result transferable beyond its recorded scope. ## When to use it Use this method after the problem and relevant segment are stated, when a consequential assumption needs a discriminating check. A check can be a desk review, usability task, interview protocol, prototype walkthrough, log analysis, or controlled comparison. Not every test is an A/B test. Select a design that can observe the claim without implying stronger causal evidence than it can provide. Stop at a draft when the outcome is not observable, the disconfirming observation is missing, required inputs are unresolved, or a necessary side-effect grant is absent. Do not invent probabilities, participant access, observations, or permission. Keep all examples in this skill synthetic. …

How to install
mdr add arcanada-one/datarim/hypothesis-validation@sha256:1e162dccf026630bThe line at the top of this page pins the label git:20261014.e0361eb, 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.
