Why Your Claude-Generated Code Falls Apart Three Weeks Later (And What to Do About It)

You open the project three weeks after you shipped it. Something simple needs changing. And then you realize: you don't fully understand the code anymore. Half of it was generated in sessions you barely remember, and Claude's decisions made sense at the time but left no trail. This isn't a Claude problem. It's a workflow problem. The Pattern I Keep Seeing Most developers who struggle with AI-assisted coding aren't writing bad prompts. The prompts are fine. The problem is that they're treating each session like a fresh request rather than a step in an ongoing build. The result: three weeks of context, decisions, and structural choices that exist only in Claude's output — not in any system you actually control. When something breaks, you're not debugging code. You're archaeologizing it. What's Actually Happening When you build something that works in a single session, confidence is high. The output is good. Claude understood the task. You ship it. But a few weeks later you need to extend
