    shopify app launch builder

    Example session with this skill installed

    I want to build a Shopify app that automatically generates and emails AI-powered personalized restock reminders to customers based on their purchase history. Use a Node/React stack.

    • Read your context and instructions
    • Compiled the shopify app launch

    Plan for: AI Restock Automator

    I have designed a production-ready blueprint for your restock reminder app. This includes a multi-tenant architecture, specific webhook handling for order history, and a red-team analysis of your background job strategy.

    App Launch Blueprint: AI Restock Automator

    1. Merchant Validation

    • Value Hypothesis: Increases Customer Lifetime Value (LTV) by reducing churn and shortening the repurchase cycle.
    • Pain Points: Manual tracking of customer usage, missed revenue opportunities, and generic marketing emails.
    • Go/No-Go: Secure 5 pilot merchants who agree that a 5% lift in repeat orders justifies a $29/mo fee.

    2. Technical Architecture

    • Tenancy: Multi-tenant PostgreSQL using shop_id scoping on all tables.

    Billing: Shopify Billing API using a recurring_application_charge (Basic: $29/mo) + usage_charge ($0.10 per AI-generated email).

    Extensions: Theme App Extension for "Notify Me" blocks on product pages; Admin Action for manual reminder triggers.

    Webhooks: Listen for orders/paid to update customer purchase timelines. Use BullMQ for processing with exponential backoff (10 retries).

    3. Commercialization Plan

    • Pricing: Free (up to 50 emails) / Pro ($29/mo + usage).
    • SEO Keywords: Restock alerts, back in stock, AI marketing, personalized reminders, customer retention.

    4. Red-Team Risk Register

    RiskSeverityMitigation Plan
    Shopify API Rate Limit (429)HighImplement leaky bucket throttling in the Node client.
    Webhook Race ConditionMediumUse updated_at timestamps to ensure older data doesn't overwrite new data.
    Data LeakageCriticalMiddleware to inject shop_id into every database query context.
    Mailer BlocklistMediumIntegrate Postmark/SendGrid via specialized background providers rather than direct SMTP.

    Next steps

    1. Initialize the project using shopify app init with the Node template.
    2. Set up the orders/paid webhook handler with an idempotency check.
    3. Register the app/uninstalled webhook to trigger the mandatory data cleanup job.

    About this skill

    The problem

    Building a Shopify app requires more than just code. Developers often struggle with complex multi-tenancy logic, webhook idempotency, and the specific security requirements needed to pass Shopify's strict App Store review.

    What it does

    • Generates a full technical architecture including tenancy models, GraphQL strategies, and background job retry logic.
    • Designs the Shopify Billing API integration with specific plan schemas and proration logic.
    • Identifies required app extensions, UI surfaces, and mandatory webhook listeners like app/uninstalled.
    • Produces a commercialization roadmap with pricing tiers and App Store SEO keywords.
    • Performs a red-team analysis to identify edge cases like API rate limits and data isolation leaks.

    Frameworks & tools

    Shopify CLI, Shopify Admin API (GraphQL), Shopify Billing API, Node.js, Ruby on Rails, PostgreSQL, Redis, and Shopify App Bridge.

    Why this beats prompting it yourself

    General LLMs often overlook Shopify-specific failure modes like webhook race conditions or mandatory GDPR webhooks. This skill applies a systematic five-phase engineering review that forces you to account for production-grade concerns before you write the first line of code.

    Use cases

    • Designing a multi-tenant SaaS application on the Shopify ecosystem.
    • Refining a technical blueprint to ensure it meets Shopify App Store requirements.
    • Stress-testing an existing app architecture for potential security or billing leaks.
    • Creating a developer-ready spec from a vague merchant problem statement.

    Known limitations

    Requires an initial app idea or problem statement to function. Recommendations are strictly limited to Shopify's public APIs and ecosystem constraints.

    Requires a core app idea to start. All output is strictly scoped to the Shopify ecosystem and public API capabilities.
