How AI Collaboration Silently Degrades Code Coherence

The problem with AI-assisted development isn't prompt quality—it's architectural coherence. Claude optimizes locally within each session, making individually reasonable decisions that silently degrade system-wide consistency. This 'hidden AI debt' emerges because the model lacks awareness of your architecture, naming conventions, and design boundaries. The solution lies not in better prompts but in explicit architectural contracts and session-based context briefings that keep AI and developer working from the same system model.
