What's Missing in Standard NestJS + PostgreSQL + Stripe Architecture
NestJS + PostgreSQL + Stripe manages data correctly, but lacks the infrastructure to track user activity and automatically segment users by engagement levels without custom implementation.
Standard NestJS + PostgreSQL + Stripe Flow vs Optimized Skene Flow
User completes onboarding
User activity tracked manually (if at all)
No automated re-engagement when activity drops
Monitor PostgreSQL 'events' table for user activity patterns via triggers
Detect when user becomes dormant (session count dropped 80%)
Trigger re-engagement email sequence with personalized content
Track re-engagement success and adjust campaigns

How Skene Fixes This
We created a Skene configuration that tracks user activity in PostgreSQL and correlates it with authentication session data. When users become dormant, it automatically sends personalized re-engagement emails that reference their last actions.
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 Retention Loop pattern for NestJS + PostgreSQL + Stripe.Copy Skene Prompt for Cursor
Generated skene.config.ts
// skene.config.ts - The Automated Way
import { defineLoop } from '@skene/sdk';
export default defineLoop({
