## What it does

This skill configures subscription A/B tests through RevenueCat MCP tools. An experiment compares two to four offerings, contrasting control `offering_a` against variants `offering_b` through `offering_d`. The assistant inspects setups via `list-offerings` and prepares a draft with `create-experiment`.

RevenueCat MCP server access is required. If an app renders paywalls via custom native code and `paywall_id` is `null`, this skill cannot modify the layout: you must edit such paywalls directly in your application codebase. Newly generated variant paywalls remain in draft status, so they require manual publishing via `publish-paywall` before enrollment begins.

Calling `start-experiment` demands explicit user approval because live traffic gets redirected. Stopping a test with `stop-experiment` is final. You cannot resume a stopped experiment, and enrolled users drop back to the default offering immediately. For modifying paywall design or store items, the workflow references `revenuecat-paywall-design` and `revenuecat-store-state`.

## When to use it
- prepare variant offerings and paywalls for an A/B test
- create an experiment draft with target metrics in RevenueCat
- swap products or introductory offers in package configurations
- publish treatment paywalls prior to starting enrollment
- manage experiment states during testing runs

## Example prompts
- Set up a draft A/B test comparing our current offering against a discounted variant.
- Duplicate our control offering into offering_b and publish its treatment paywall.
- Pause the active RevenueCat experiment to halt new customer enrollments.

# Setting up and managing experiments

A RevenueCat experiment compares two to four offerings: `offering_a` (the control) against `offering_b`–`offering_d` (the treatments). Enrolled customers are served their variant's offering instead of the project's current offering. Setting up an experiment means preparing one offering per variant, then creating the experiment as a draft.

Refer to the MCP tool schemas for the exact parameters of each tool; the `create-experiment` schema also lists the available experiment types with their recommended primary and secondary metrics.

## Preparing the variants

Keep the variants identical except for the one aspect under test, otherwise results cannot be attributed to the change. For example, when measuring the impact of a lower subscription price, both variants should share the same paywall design and packages, differing only in the price of the products.

**Control.** When the control variant is "what production does today", pass the current offering (`is_current` in `list-offerings`) directly as `offering_a_id` — do not duplicate it. Duplicate only when control itself needs changes relative to production.

**Treatments.** First check with `list-offerings` whether an offering already exists that matches what the treatment should serve, and reuse it instead of duplicating. Otherwise, start each treatment from a duplicate of the offering closest to it (usually the control offering). `duplicate-offering` copies the packages (attaching the same existing products) and, if the source offering has a paywall, also copies it as a new unpublished draft; it returns the new offering, including its new `paywall_id`. Pass `source_paywall_version: published` so the treatment copies the paywall customers see in production rather than unfinished draft edits; this fails when the source paywall was never published, so use the default (`draft`) only then. Then apply the one change under test:
```
