Building Maintainable AI Code: Why Session Structure Beats Prompt Quality

The deterioration of AI-generated code over time isn't a limitation of AI tools like Claude—it's a consequence of treating each session as an isolated request rather than a step in an ongoing architectural process. Developers who structure their workflow to maintain context across sessions, verify output against existing patterns, and treat each interaction as a deliberate handoff build systems that remain maintainable long-term. This insight reframes AI-assisted development as a discipline requiring structured workflow practices, not merely better prompts.
