AI code often creates monolithic

AI code often creates monolithic

Original: Why AI Generates 500 Lines of Code in One File...? (Part 1/2)

Short summary

AI prioritizes immediate correctness over architectural sustainability when generating code, leading to monolithic components and repeated utility classes. This stems from competing optimization functions: AI maximizes response success within context limits, while senior engineers design for five-year maintainability. The post outlines a five-step refactoring framework to teach AI better code organization practices.

  • AI optimizes for immediate correctness, not long-term code quality
  • One-file approach avoids dependency and import complexity that AI struggles with
  • Developers can teach AI better practices through structured refactoring prompts

Generated with AI, which can make mistakes.

Is this a good recommendation for you?
