What it does
This skill teaches an AI agent to act as a conversion specialist for in-app upgrade moments, such as a feature lock, a usage limit, or a trial ending. When installed, the agent asks about your free and paid plans, suggests when to show the upgrade prompt, drafts paywall copy and layouts, and proposes A/B tests. It also includes a reference guide for consumer iOS and Android subscription apps covering topics like yearly-first plans, trials, and store fees.
Great for
- Product managers or founders running a freemium or trial-based app who want to improve upgrade conversion
- Mobile app developers planning a subscription paywall inside onboarding or after key actions
- Growth marketers designing trial expiration or usage-limit upgrade prompts
Skip it if
- Public pricing page work, which the skill itself says belongs to the cro skill instead (wrong tool for that job)
- Setting the actual price level or pricing model, which the skill refers to the separate pricing skill for
- Dark-pattern tactics such as hidden close buttons or fake countdowns; the skill lists these as anti-patterns, but the agent should not be used to implement them
Try asking
- “Help me design a paywall for when free users hit their 3-project limit in my app.”
- “Write a trial expiration screen for a subscription app that warns at 7, 3 and 1 days.”
- “Suggest A/B tests to improve trial-to-paid conversion in my mobile app.”
- “Review my feature lock upgrade modal and tell me how to make it less pushy.”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Give the agent your current conversion rate, free tier limits, and what your users do before they hit the paywall, so recommendations fit your product.
- If you have a product marketing context file (such as .agents/product-marketing.md), the skill will read it first, so keep it updated.
- Ask for mobile-specific advice explicitly if you build a consumer iOS or Android app, so the agent loads the mobile reference guide.
