Poor Code Quality in AI-Generated Projects

AI-generated codebases frequently have duplicated logic, inconsistent patterns, missing error handling, no TypeScript strict mode, and poor separation of concerns. This makes maintenance and feature additions increasingly difficult.

Frequently Asked Questions

Is AI-generated code inherently bad quality?

Not always, but AI tools optimize for working output rather than maintainable architecture. The code works but often lacks the structure, consistency, and error handling that professional developers build in.
