theoutlines/growth-skills

Claude skills for growth work on mobile subscription apps, made for product designers. Share the screens of any part of the user's journey and get a score for what can be changed on screen, store and dark-pattern flags, and a ranked list of tests backed by published A/B tests and public benchmarks.
Made by a monetization design lead for day-to-day work on onboarding, paywalls, upsells, retention and churn.
Works with: Claude Code and the Claude app as one plugin, and any agent that supports the open Agent Skills format (Codex, Gemini CLI, Cursor, GitHub Copilot). See Install.
## What's inside
Skills follow the user's journey. Not sure which one you need? Start with growth-router: share the screens and it picks.
| Part of the journey | Skill | What it reviews |
| Start here | growth-router | Sorts screens or a question to the right skill, or combines two |
| Web funnel | web2app-teardown | Ad landing, web quiz, plan screen, web paywall, checkout, the way into the app, and the in-app "buy on the web" screen |
| Onboarding | onboarding-teardown | First launch to the first paywall and what happens when it's closed |
| Onboarding + paywall | flow-teardown | Onboarding, the first paywall and the seam between them as one system: tactics on the wrong side of the seam |
| Upsells | upsell-teardown | Locked features, limits and counters, contextual paywalls, upgrade screens for payers, AI credits |
| First weeks to renewal | retention-teardown | Welcome after purchase, notification ask, reminders, streaks, recaps, trial-ending notice, welcome back, rating ask |
| Cancel flow | cancel-flow-teardown | Manage subscription, reason survey, save offers, confirmation, resubscribe |
| The whole journey | growth-map | Which growth levers the app uses and which nobody has touched, stage by stage, and where to start |
| Your own numbers | funnel-check | Your funnel against public benchmarks with matching definitions; finds the leakiest step and the teardown for it. Can pull numbers from Amplitude, Mixpanel, RevenueCat or Adapty when connected |
| A variant before launch | variant-check | Paywall or onboarding A vs B before live traffic: which mechanics B changes, whether the test can see it, what the winning versions had that B lacks, a clarity pretest to run first. Figma frames, screenshots or a description |
| A finished test | test-readout | Did B really win? Trust checks, the likely range, where the difference came from (how many paid vs which plans), keep / kill / iterate. Pulls the numbers from Amplitude, Mixpanel, RevenueCat or Adapty when connected |
Included: everything in Subscription Skills, for the paywall itself and the numbers:
| Skill | What it answers |
| subscription-benchmarks | Routes a numbers question to the right report and keeps denominators apart |
| state-of-subscription-apps-2026 | RevenueCat: download→trial, trial→paid, LTV, retention, renewals, refunds |
| state-of-in-app-subscriptions-2026 | Adapty: LTV curves, retention by plan, prices by region, placement, AI apps |
| state-of-web2app-2026 | FunnelFox: web funnels, web pricing, upsells, web vs app LTV |
| subscription-pricing-index | Adapty Pricing Index: weekly, monthly and annual prices in 64 countries |
