The blog post 'The Shapes of AI Code' by Srijan R. Shetty discusses three different coding modes when integrating AI: Pristine Core, Slop Shell, and Side Stuff. The author explains their workflow involving AI-generated code, emphasizing the importance of defining test cases first and balancing creative freedom in less critical code sections with rigorous testing in the core areas. This pragmatic approach allows developers to leverage AI effectively without jeopardizing critical business functions.
