PROTOTYPE CODE IS NOT PRODUCTION CODE (AND THAT'S OKAY)

Summary from the TLDR Design newsletter

Prototype code and production code serve fundamentally different purposes: prototype code explores ideas quickly without constraints, while production code must operate at scale with proper security and reliability considerations. Modern AI coding tools make it dangerously easy to skip the crucial distinction by encouraging developers to generate and ship code in a single step. The solution is maintaining two protected spaces with a deliberate pathway between them - one for unconstrained exploration and another for rigorous production engineering.
