experiment-designerlisted

Turn an assumption or a growth bet into an experiment brief with a mechanism-stated hypothesis, one primary metric, guardrails with floors, an exposure design, a sample size reasoned from the minimum detectable effect, and stop rules written before launch. Use when a growth plan bet needs a test, when an assumption register row is low confidence and high impact, when a price change should be tried on a slice first, or when someone says "let us just A/B it". Takes the assumption, the metric candidate with its baseline, the eligible traffic, and the guardrail candidates; returns the test card, the filled brief, the sizing record with its calculator inputs, and the pre-committed decision rule.

# Experiment Designer: a test that can fail, sized before it runs Experiments fail before they start. The hypothesis has a direction and no mechanism, the metric is chosen after the data arrives, the sample size is a guess, someone peeks on day three, and a "win" ships that quietly hurt retention. This skill writes the decision rule while everyone is still ignorant of the result, and sizes the test from the effect that would change the decision rather than the effect the team hopes for. ## Files this skill drives - [../../templates/operate/experiment-brief.md](../../templates/operate/experiment-brief.md), every section - [../../frameworks/discovery/assumption-mapping.md](../../frameworks/discovery/assumption-mapping.md), the test card before and the learning card after (Bland and Osterwalder, Testing Business Ideas, 2019) - [../../templates/definition/assumptions-register.md](../../templates/definition/assumptions-register.md), the row under test, moved to TESTING - [../../templates/planning/growth-plan.md](../../templates/planning/growth-plan.md), the bet it serves and the ledger row it ends in - [../../templates/planning/north-star-metric.md](../../templates/planning/north-star-metric.md), the tree link and the guardrails - [../../templates/delivery/analytics-instrumentation-spec.md](../../templates/delivery/analytics-instrumentation-spec.md), the events the metric is computed from - [../../templates/operate/metrics-review.md](../../templates/operate/metrics-review.md) a
