# I Created a Pagination Challenge… And AI Missed the Real Problem

📄 Pagination looks simple. Page → limit → slice → done. That’s what I thought. So I created a small challenge on VibeCode Arena. And things got interesting. 🚨 The Problem The logic works perfectly… on static data. But real systems are not static. Data keeps changing. Users keep adding and removing items. 🧠 What Goes Wrong? In real-world scenarios: New data gets inserted Old data gets deleted Users refresh pages And suddenly: 👉 You see duplicate data 👉 Or you miss some records This is a very common production bug. 🤯 What I Observed When AI models tried this: Most gave basic slice-based logic Some didn’t consider dynamic data Very few suggested cursor-based pagination The code works. But the system is unreliable. 🔥 Try It Yourself I created this challenge to test real-world API thinking. 👉 Try it here: https://vibecodearena.ai/duel/b772342a-30ee-4d38-838c-c2c888dfffa7 Can you: Prevent duplicate records? Handle dynamic data? Design a scalable pagination system? 💡 Final Thought Pagination
