What they did
They asked Replit Agent to create the full app from scratch. The agent pulled regional population data from the American Kennel Club and used it to assign rarity values for dog catches, then finished the dog-themed collecting experience.
How it went
The app was completed as a collect-them-all dog game. No problems or missing features were reported in the outcome.
Tips
If your app depends on outside data, make sure the source is reliable and the rarity rules are easy to verify. Stop the agent to review anything that changes live data, store content, or launch settings before it goes further.

Create the full app, including browsing, collecting, and a visible collection screen. Before you make any irreversible changes, deployments, purchases, deletions, or submissions, pause and ask for my approval. When the app is ready, deploy it and show me where the rarity tiers come from.
