When I first started using Claude Code, I had a naive approach to working with it. I would describe the task directly in the prompt, press Enter, and cross my fingers. If the agent made mistakes, I would tell it how to fix them. For small tasks, this can be good enough, but as the task grows in complexity, this approach reveals several significant drawbacks. When Simple Doesn’t Scale The first problem is that the conversation becomes the only source of truth about the task.
