I Built a Self-Improving RAG System for Claude Code. Here is What It Learned.

De I was debugging the same authentication error for the third time this month. Same error. Same root cause. Same fix. Claude Code had solved this exact problem two weeks ago - but it didn't remember. Each session starts fresh. No memory of what worked, what failed, or what patterns emerged. That's a massive waste of debugging time. So I built a system to fix it. The Problem With Stateless AI Claude Code is powerful, but it has a fundamental limitation: every session starts from zero.
