Stop Re-Explaining Your Codebase to Claude Code Every Session

Claude Code doesn't remember anything between sessions. You already know this. What you might not have measured is how much time you actually lose to it. Developers who tracked their Claude Code sessions found 59+ documented compactions in a single project. Each one wiped working knowledge mid-session. Each session start required the same re-orientation: re-explain the architecture, re-establish the naming conventions, re-litigate decisions that were already settled two sessions ago.
