description	Use when the user asks to "design an A/B test", "set up a creative/landing test", "run an incrementality test", or "is this result statistically and practically material?"; produces a hypothesis, variant matrix, sample-size/duration/power plan, and a documented effect/uncertainty read from own exported results. It applies only a precommitted owner-approved action rule; the statistical helper never chooses a business action. Not for producing variants — use ad-creative-builder; not for reading back one shipped change — use paid-measurement-loop. 广告AB测试设计/实验设计/显著性判定/增效测试

when_to_use	Use when designing a creative/landing A/B/n or incrementality test, or when reading effect size, uncertainty, and guardrails from a finished own-data test. Apply a business action only when its owner and decision rule were precommitted; otherwise return decision UNDECIDED. Not for generating variants (use ad-creative-builder) or reading back one already-shipped change (use paid-measurement-loop).

Ad Test Designer

Designs paid-ad creative/landing A/B/n and incrementality tests and reads them out: hypothesis, variant matrix, sample-size/duration/power plan, effect size, uncertainty, practical-effect status, and guardrail state. This skill owns experiment design + statistical interpretation. It may apply an owner-approved, precommitted action rule, but it never treats a p-value or helper output as an automatic business decision. It does not produce variants (ad-creative-builder), read back one already-shipped change (paid-measurement-loop), or do cross-channel reporting (performance-analyzer).

Quick Start

Design an A/B test for two landing-page hero variants. Baseline CVR is 3%, I want to detect a 15% lift. Goal is DR.

I have 4 RSA creative variants to test on a prospecting set. Build the variant matrix, sample size, and run duration.

Here's my finished test results CSV (variant, sessions, conversions). Is the winner significant — promote or kill?

Skill Contract

• Expected output: a test design (hypothesis, variant matrix, immutable test/variant/measurement binding, primary/secondary/guardrail metrics, sample-size + duration + power plan) and/or a read-out bound to that exact design (effect estimate, interval, statistical flag, practical-effect flag, guardrails, and either an owner-governed recommendation or decision: UNDECIDED).
• Reads: what the user wants to test, the ROAS profile (direct-response|prospecting|incremental-profit), baseline CVR/CTR and traffic volume, stable control/candidate refs, the exact creative or landing artifact hash, and the measurement-contract ref/hash; for a read-out, the user's own exported results CSV (variant, sessions/impressions, conversions/clicks) plus the original binding.
• Writes: a user-facing test-design or read-out doc plus a ### Handoff Summary.
• Promotes: the chosen hypothesis, design parameters, calculated read-out, and any explicitly owner-approved action (ask before writing memory).
• Done when: a falsifiable hypothesis is stated; the matrix isolates one variable per variant; the control, candidate, variant hash, signal spec, and measurement contract are bound; baseline, MDE, alpha, power, multiplicity/sequential policy, duration, and guardrails are declared; and a read-out reports effect/interval/statistical/practical flags with Calculated provenance against the same binding. A mismatch returns ; without a precommitted action rule and owner, return .
