Does Skene work with Next.js + PlanetScale + NextAuth?

Yes! Skene is tool-agnostic and works with Next.js + PlanetScale + NextAuth and any tech stack. The Skene SDK integrates with your existing codebase by analyzing your database schema, API routes, and authentication setup. After running `npx skene init`, Skene automatically detects your stack and generates the appropriate configuration.

Is the manual implementation code secure?

The manual code shown above is a simplified example and has several security concerns: it lacks proper input validation, doesn't handle SQL injection risks, and has no rate limiting. Additionally, the polling approach creates unnecessary database load. Skene handles all of these concerns automatically with built-in security best practices, proper error handling, and optimized queries.

How long does it take to implement Retention Loops manually vs with Skene?

Implementing Retention Loops manually typically takes 2-3 days of development time, including setting up workers, writing database queries, handling edge cases, and testing. With Skene, you can install the same functionality in under 5 minutes by copying the prompt into Cursor or Claude Code. Skene automatically generates the `skene.config.ts` file and integrates with your existing infrastructure.

What's Missing in Standard Next.js + PlanetScale + NextAuth Architecture

Next.js + PlanetScale + NextAuth manages data correctly, but lacks the infrastructure to track user activity and automatically segment users by engagement levels without custom implementation.

Standard Next.js + PlanetScale + NextAuth Flow vs Optimized Skene Flow

Standard Flow

1

User completes onboarding

2

User activity tracked manually (if at all)

3

No automated re-engagement when activity drops

Skene Flow

1

Monitor PlanetScale 'events' table for user activity patterns via branching

2

Detect when user becomes dormant (hasn't logged in for 14 days)

3

Trigger re-engagement email sequence with personalized content

4

Track re-engagement success and adjust campaigns

How Skene Fixes This

The Skene setup for Next.js + PlanetScale + NextAuth tracks user activity and segments users by engagement. It automatically triggers retention campaigns for dormant users and celebrates milestones for active users.

Implementation Comparison

Using Skene Infrastructure

Auto-managed state. Installed via Prompt.

Install via Prompt

cursor.mdc

@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 Next.js + PlanetScale + NextAuth.

Copy Skene Prompt for Cursor

Generated skene.config.ts

skene.config.ts

// skene.config.ts - The Automated Way
import { defineLoop } from '@skene/sdk';

export default defineLoop({
  type: 'retention',
  opinion: 'Detect dormant users and trigger personalized re-engagement campaigns',
  steps: [
    {
      trigger: {
        type: 'schedule',

      condition: {
        type: 'query',
        query: `SELECT * FROM users WHERE last_activity_at < NOW() - INTERVAL '7 days' AND re_engagement_sent = false`,
