A large codebase makes an AI assistant slower, not faster, because the model cannot hold it. PIM, for Prompt, Iterate, Modularise, is the habit that keeps code small enough for the machine to reason about.

AI coding tools produce working code fast. The problem is the code nobody can safely change six months later. Here is what that costs and how to tell if you have it.
