What's Missing in Standard NestJS + PostgreSQL + Stripe Architecture
Stripe handles subscription billing perfectly, but it doesn't track usage or enforce feature limits. You'd need to manually check subscription status and implement your own usage tracking in PostgreSQL. Stripe webhooks fire for payment events, but not for usage milestones.
Standard NestJS + PostgreSQL + Stripe Flow vs Optimized Skene Flow
User subscribes via Stripe
Subscription status stored in PostgreSQL
Features accessible but no usage limits enforced
Track usage in PostgreSQL 'subscriptions' and 'usage' tables
Detect when free tier user hits limit (e.g., 100 API calls)
Block feature access and trigger upgrade prompt email
Track conversion from free to paid

How Skene Fixes This
This Skene Prompt installs freemium gating into NestJS + PostgreSQL + Stripe by monitoring PostgreSQL usage tables and Stripe subscription status. When free users hit limits, it automatically blocks features and triggers upgrade prompts.
Implementation Comparison
Using Skene Infrastructure
Install via Prompt
@task: Initialize Skene.
@action: Analyze my local code, validating subscription via `npx skene login`, and generate `skene.config.ts` to implement the Freemium Gating pattern for NestJS + PostgreSQL + Stripe.Copy Skene Prompt for Cursor
Generated skene.config.ts
