Why AI Assistants Write This Bug

AI tools add build tooling, testing frameworks (jest, vitest), and types directly into dependencies instead of devDependencies.

AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.
