Working with Existing Code

'Working With Existing Code' is about learning to see code the way AI sees it — as fragments, and without context. It's also about understanding how to provide clarity, boundaries, and intent that let AI act safely within 'an existing system'. This topic teaches us how to reveal just the right parts of the codebase, how to describe relationships that AI 'cannot infer', and how to collaborate with AI in a way that preserves structure, purpose, and architectural integrity.
