# 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

```text
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.
```
```text
I have 4 RSA creative variants to test on a prospecting set. Build the variant matrix, sample size, and run duration.
```
```text
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 `NEEDS_INPUT/UNDECIDED`; without a precommitted action rule and owner, return `decision: UNDECIDED`.
- **Primary next skill**: [ad-creative-builder](../ad-creative-builder/SKILL.md) (to produce the winning direction) or [paid-measurement-loop](../../scale/paid-measurement-loop/SKILL.md).

### Handoff Summary

> Emit the standard shape from [skill-contract.md §Handoff Summary Format](../../../references/skill-contract.md).

## Data Sources

> See [CONNECTORS.md](../../../CONNECTORS.md) for tool category placeholders. Every input is the user's **own data, manually exported**. Keyed ad-platform APIs (Google Ads SDK, Meta Marketing API) are an optional Tier-2/3 MCP convenience — never required to design a test or read one out.

> **Statistical facts (keyless):** `python3 "${CLAUDE_PLUGIN_ROOT}/scripts/connectors/experiment.py" proportion --control <conv> <n> --variant <conv> <n> --alpha <alpha> --min-lift <relative-bar>` returns rates, effect size, intervals, p-value, and separate statistical/practical flags. Revenue/AOV-style samples use `continuous`; prospective sizing uses `samplesize`. Every derived value is `Calculated`; the helper deliberately returns no winner, promote, rollback, or kill action.

| Need | Source export (own data) | Category |
|------|--------------------------|----------|
| Baseline CVR/CTR, traffic volume | campaign report | `~~ad platform` |
| Test results (variant, sessions, conversions) | experiment/results CSV export | `~~ad platform`, `~~web analytics` |
| Conversion truth set for the read-out | GA4 / ecommerce export | `~~web analytics`, `~~ecommerce` |

**With manual data only:** for a design, ask for the baseline CVR/CTR, traffic/day, and the minimum lift worth detecting. For a read-out, ask for the results CSV with
